ABSTRACT

The Indus Valley civilization shows that Indian subcontinent had a leadership in

the advancement in construction Technology and Industry over the world But

unfortunately this part of the sub-continent especially Bangladesh could not

cope with the modern technological advancementConstruction technologies can on the basis of their content of labor and

equipment be classified as equipment intensive labor intensive and labor basedtechnology In recent years technological innovation in design analysis

construction materials construction methods etc have resulted in significant

changes in construction industry Computer aids have improved capabilities for

generating worth designs reducing th time requirement to produce alternative

designs to ensure safety with economy New technologies not only haveenhanced the quality of construction but also have shortened the time for shop

fabrication and field erection Construction methods have advanced throughvarious stages of mechanization and automation including the latest

development of construction robotics That means trend is advanced

technologyIn this study 25 numbers of six to nine storied buildings and 4 numbers of

twenty to thirty storied buildings have been studied It has been observed that

the construction industry in Bangladesh dominated by labor-intensive

technology lower grade material and primitive construction procedure In mostof the cases 29 more cost involvement has been observed These madeconstruction indl1stry of Bangladesh an inefficient one Use of high qualitymaterial easily saves huge monitory loss in this sector This will require active

participation of Engineers in design house and in field Further detail study may

enhance this fact elaboratelyDifferent sizes 10 numbers building of different excavation depth have been

studied Of these considering PWD stpound jard rate of works it has been observed

that for deeper excavation excavator or equipment intensive technology ischeaper than labour intensive excavation For ending conclusion of equipment

intensive excavation require further detailed investigationBangladesh cOl1ld regain leadership in the construction industry over the world

through accepting and participating in the advancement of the modern

technologies The scopes are waiting ahead Entrepreneur especially the

Engineers should come forward to take the challenge to advance Bangladesh in

that directionAuthor

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

Specific objectives of this study are

bull To study the exiting technological parameters in present day building

construction in Bangladesh

bull To study the economy of scale and factors as they relate to-

(a) Humnware

(b) Infoware and

(e) Hardware

CHAPTER 2

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

51

4218 Analysis and Result

For analysis purpose here considered a six storied building The analysis has

been performed by STAADIPro software 3-D model of assumed building amp

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

ABSTRACT

The Indus Valley civilization shows that Indian subcontinent had a leadership in

the advancement in construction Technology and Industry over the world But

unfortunately this part of the sub-continent especially Bangladesh could not

cope with the modern technological advancementConstruction technologies can on the basis of their content of labor and

equipment be classified as equipment intensive labor intensive and labor basedtechnology In recent years technological innovation in design analysis

construction materials construction methods etc have resulted in significant

changes in construction industry Computer aids have improved capabilities for

generating worth designs reducing th time requirement to produce alternative

designs to ensure safety with economy New technologies not only haveenhanced the quality of construction but also have shortened the time for shop

fabrication and field erection Construction methods have advanced throughvarious stages of mechanization and automation including the latest

development of construction robotics That means trend is advanced

technologyIn this study 25 numbers of six to nine storied buildings and 4 numbers of

twenty to thirty storied buildings have been studied It has been observed that

the construction industry in Bangladesh dominated by labor-intensive

technology lower grade material and primitive construction procedure In mostof the cases 29 more cost involvement has been observed These madeconstruction indl1stry of Bangladesh an inefficient one Use of high qualitymaterial easily saves huge monitory loss in this sector This will require active

participation of Engineers in design house and in field Further detail study may

enhance this fact elaboratelyDifferent sizes 10 numbers building of different excavation depth have been

studied Of these considering PWD stpound jard rate of works it has been observed

that for deeper excavation excavator or equipment intensive technology ischeaper than labour intensive excavation For ending conclusion of equipment

intensive excavation require further detailed investigationBangladesh cOl1ld regain leadership in the construction industry over the world

through accepting and participating in the advancement of the modern

technologies The scopes are waiting ahead Entrepreneur especially the

Engineers should come forward to take the challenge to advance Bangladesh in

that directionAuthor

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

Specific objectives of this study are

bull To study the exiting technological parameters in present day building

construction in Bangladesh

bull To study the economy of scale and factors as they relate to-

(a) Humnware

(b) Infoware and

(e) Hardware

5

13 Methodology

CHAPTER 2

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

technological system and it includes for example the organizations for the

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

ABSTRACT

The Indus Valley civilization shows that Indian subcontinent had a leadership in

the advancement in construction Technology and Industry over the world But

unfortunately this part of the sub-continent especially Bangladesh could not

cope with the modern technological advancementConstruction technologies can on the basis of their content of labor and

equipment be classified as equipment intensive labor intensive and labor basedtechnology In recent years technological innovation in design analysis

construction materials construction methods etc have resulted in significant

changes in construction industry Computer aids have improved capabilities for

generating worth designs reducing th time requirement to produce alternative

designs to ensure safety with economy New technologies not only haveenhanced the quality of construction but also have shortened the time for shop

fabrication and field erection Construction methods have advanced throughvarious stages of mechanization and automation including the latest

development of construction robotics That means trend is advanced

technologyIn this study 25 numbers of six to nine storied buildings and 4 numbers of

twenty to thirty storied buildings have been studied It has been observed that

the construction industry in Bangladesh dominated by labor-intensive

technology lower grade material and primitive construction procedure In mostof the cases 29 more cost involvement has been observed These madeconstruction indl1stry of Bangladesh an inefficient one Use of high qualitymaterial easily saves huge monitory loss in this sector This will require active

participation of Engineers in design house and in field Further detail study may

enhance this fact elaboratelyDifferent sizes 10 numbers building of different excavation depth have been

studied Of these considering PWD stpound jard rate of works it has been observed

that for deeper excavation excavator or equipment intensive technology ischeaper than labour intensive excavation For ending conclusion of equipment

intensive excavation require further detailed investigationBangladesh cOl1ld regain leadership in the construction industry over the world

through accepting and participating in the advancement of the modern

technologies The scopes are waiting ahead Entrepreneur especially the

Engineers should come forward to take the challenge to advance Bangladesh in

that directionAuthor

CHAPTER 1

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

Specific objectives of this study are

bull To study the exiting technological parameters in present day building

construction in Bangladesh

bull To study the economy of scale and factors as they relate to-

(a) Humnware

(b) Infoware and

(e) Hardware

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

also they are not interested to go for such type of management

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

ABSTRACT

The Indus Valley civilization shows that Indian subcontinent had a leadership in

the advancement in construction Technology and Industry over the world But

unfortunately this part of the sub-continent especially Bangladesh could not

cope with the modern technological advancementConstruction technologies can on the basis of their content of labor and

equipment be classified as equipment intensive labor intensive and labor basedtechnology In recent years technological innovation in design analysis

construction materials construction methods etc have resulted in significant

changes in construction industry Computer aids have improved capabilities for

generating worth designs reducing th time requirement to produce alternative

designs to ensure safety with economy New technologies not only haveenhanced the quality of construction but also have shortened the time for shop

fabrication and field erection Construction methods have advanced throughvarious stages of mechanization and automation including the latest

development of construction robotics That means trend is advanced

technologyIn this study 25 numbers of six to nine storied buildings and 4 numbers of

twenty to thirty storied buildings have been studied It has been observed that

the construction industry in Bangladesh dominated by labor-intensive

technology lower grade material and primitive construction procedure In mostof the cases 29 more cost involvement has been observed These madeconstruction indl1stry of Bangladesh an inefficient one Use of high qualitymaterial easily saves huge monitory loss in this sector This will require active

participation of Engineers in design house and in field Further detail study may

enhance this fact elaboratelyDifferent sizes 10 numbers building of different excavation depth have been

studied Of these considering PWD stpound jard rate of works it has been observed

that for deeper excavation excavator or equipment intensive technology ischeaper than labour intensive excavation For ending conclusion of equipment

intensive excavation require further detailed investigationBangladesh cOl1ld regain leadership in the construction industry over the world

through accepting and participating in the advancement of the modern

technologies The scopes are waiting ahead Entrepreneur especially the

Engineers should come forward to take the challenge to advance Bangladesh in

that directionAuthor

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

CHAPTER 2

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

Page 5: TECHNOLOGY FORCONSTRUCTION INDUSTRY OFBANGLADESH

ABSTRACT

The Indus Valley civilization shows that Indian subcontinent had a leadership in

the advancement in construction Technology and Industry over the world But

unfortunately this part of the sub-continent especially Bangladesh could not

cope with the modern technological advancementConstruction technologies can on the basis of their content of labor and

equipment be classified as equipment intensive labor intensive and labor basedtechnology In recent years technological innovation in design analysis

construction materials construction methods etc have resulted in significant

changes in construction industry Computer aids have improved capabilities for

generating worth designs reducing th time requirement to produce alternative

designs to ensure safety with economy New technologies not only haveenhanced the quality of construction but also have shortened the time for shop

fabrication and field erection Construction methods have advanced throughvarious stages of mechanization and automation including the latest

development of construction robotics That means trend is advanced

technologyIn this study 25 numbers of six to nine storied buildings and 4 numbers of

twenty to thirty storied buildings have been studied It has been observed that

the construction industry in Bangladesh dominated by labor-intensive

technology lower grade material and primitive construction procedure In mostof the cases 29 more cost involvement has been observed These madeconstruction indl1stry of Bangladesh an inefficient one Use of high qualitymaterial easily saves huge monitory loss in this sector This will require active

participation of Engineers in design house and in field Further detail study may

enhance this fact elaboratelyDifferent sizes 10 numbers building of different excavation depth have been

studied Of these considering PWD stpound jard rate of works it has been observed

that for deeper excavation excavator or equipment intensive technology ischeaper than labour intensive excavation For ending conclusion of equipment

intensive excavation require further detailed investigationBangladesh cOl1ld regain leadership in the construction industry over the world

through accepting and participating in the advancement of the modern

technologies The scopes are waiting ahead Entrepreneur especially the

Engineers should come forward to take the challenge to advance Bangladesh in

that directionAuthor

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

22

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

technology Following software and tools are now using in Bangladesh

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

CHAPTER 2

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

technology Following software and tools are now using in Bangladesh

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

Specific objectives of this study are

bull To study the exiting technological parameters in present day building

construction in Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

new particularly computer based technology

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

51

4218 Analysis and Result

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

Specific objectives of this study are

bull To study the exiting technological parameters in present day building

construction in Bangladesh

bull To study the economy of scale and factors as they relate to-

(a) Humnware

(b) Infoware and

(e) Hardware

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

51

4218 Analysis and Result

For analysis purpose here considered a six storied building The analysis has

been performed by STAADIPro software 3-D model of assumed building amp

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

CHAPTER 1

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

51

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

new particularly computer based technology

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

51

4218 Analysis and Result

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

CHAPTER 2

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

technology Following software and tools are now using in Bangladesh

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

CHAPTER 1

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

technology Following software and tools are now using in Bangladesh

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

Labours and technicians are unskilled

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)

INTRODUCTION

11 Development of Construction Technology

Building is the earliest form of technology In civil engineering construction

From the most primitive times humans required protection from the wild

animal elements of nature changing seasons and predators in natural

shelters such as caves and rock overhangs

Step by step they learned to improve their caves with inlaid stone floors

walls at the entrances and fireplaces Ultimately they began creating entirely

new habitats in locations that had no natural shelter

Shetters built from natural material~ indicate that they had knowledge of the

stress strain and insulation properties (heat cold and water-proofing) of the

materials used The use of hand-made bricks or stone blocks indicated

knowledge of properties such as compression forces The symmetrical

shapes of the designs indicated the knowledge and application of the

principles of geometry

Most communities had their own distinctive styles lor bUilding their houses

and archaeologists have uncovered many examples through the ages

The bUilding trade is the earliest form of civil engineering construction Up to

13 century building technology in the sub-continent fell under three

category (a) Thatchery and mud houses made of thatched roof of bamboo

straw grass reed etc lb) stone masonry which included hewing laying and

carving of stone and (c) Brick masonry construction consisting of lime-surki

mortar in the city areas Between 13 and 18h century the feudal monarchs

and the land lords constructed monumental bUildings After the Industrial

2

revolution in the 180 century construction of factory buildings labor sheds

ware houses etc became the major construction activities With the

invention of the steam engine in the 18 century development of railways

started Besides the construction of roads ports and harbors inland and

offshore navigation developed simultaneously after the Second World War

reconstruction of the war ravaged infrastructure brought a boom In the civil

engineering construction Civil engineering also has attained modernization

an eventually in the seventies the development of chips and micro chips and

the high capacity single chip microprocessor made possible the development

of the micro computers The computer software technology has also

developed very fast simultaneously The development of the optical fiber

and the satellite technology has made a revolution and the internet has

brought the information technology to a stage which was unimaginable even

a decade ago As result knowledge based industries now dominate over the

previous machinery based industries Traditional construction industry as

gradually becomes obsolete and ineffective worldwide in these high tech

eras This new situation put construction industry a new challenge

In modern times the civil engineers built dams sluices regulators barrages

pump houses and p ower generation and many other structures which were

believed to be impossible to construct Gigantic modern off-shore structures

are now built which go to several hundred meters below sea level In the

field of bridge construction enormous progress have been achieved Bridges

has now become relatively cheap and can be built in extremely short timeThe most ambitious bridge development ever realized is certainly the Akashi-

Kaiko Bridge in Japan with a span of 1990 meter This gigantic endeavor at

the early age where only possible due to very sophisticated and heavy

erection equipment developed The successful construction of channel

tunnel Bull twinkle (492 m worlds tallest offshore platform) Louisianan

offshore oil port supertanker unloading capacity of 100000 barrel an houri

Kansai international airport a port reclaimed from sea bed containing

extremely soft soill testify to development capability of the civil engineeringprofession in modern times it will not be out of place to mention that during

the sixties intensive urbanization in many developed countries saw the

3

spectacular revolutionary concepts such as wall frame Interaction tube-in-

tube bundle tubes diagonally braced frame and compOSite construction

pioneered the high rise growth Developments of intelligent buildings that

can respond to earthquake and fire hazards are in the making

In recent years (Information agel technological innovation in design

materials and construction methods have resulted in significant changes in

construction costs Computer aids have improved capabilities for generation

quality designs as well as reducing the time required to produce alternative

designs New equipments and materials not only have enhanced the quality

of constructIOn but also have shortened the time for shop fabrication and

field erection Construction methods have gone through various stages of

mechanization and automation including the latest development of

construction robotics

The Global Trend

Competition in global market for better amp economic building construction is

increasing day by day Construction organizations are realizing that

responsiveness to market demands and adaptability to changing condition

Competitive prices are the hallmarks of successful enterprise Therefore

every construction organization wants to lower the cost by alternate deSign

interchanging material strength amp type uSing modern construction methods

and proper management So construction world is going for new technology

and saving both time and cost

The Bangladesh Context

Bangladesh has come a long way since its independence But a very few

organizations have adopted new construction technology and ability to build

high strength material with quality After 2004 due to WTD and GATS

Bangladesh market has to be made open to outside countries and most of

the organization will face difficult challenges from the competitors of other

countries To face this challenge effectively construction organizations need

4

to be more responsive to market demands lower the prices by choosing

proper construction technology in all stages of construction as well as

improve quality of material If construction organizations of Bangladesh will

able to qualify with other countries in competition they would have to

opportunity to work abroad

Bangladesh is one of the least developed countries in the world Regrettably

In Bangladesh most of the construction methods and design are oriented by

conventional method Though volume of building construction is large but

modern construction method and equipment facilities in most of the cases

are absent Only a small number of projects have been done or ongoing With

theses modern facilities Remarkable new and high strength material are also

not using in Bangladesh Only in some national bridgeroad construction

project modern equipment and material were used in Bangladesh Due to

absent of new and high strength materials new technologies new

equipments quality as well as effiCiency of building construction are very

poor

12 Objective of the Project

Bangladesh is one of the least developing countries Contemporary

construction technology With high strength materials are not often uSing inbUildingconstruction sector The objective of this study IS to find out what

type of technology and materials are being using for building construction In

addition to find out if better technology is available why these are not

being accepted at present in construction sector of Bangladesh

TECHNOLOGIES IN CONSTRUCTION INDUSTRY

21 Introduction to Technology in Construction Industry

McGraw Hill Encyclopedia Defines Technology as 11

Technology is closely related to science and engineering Science deals with

humans understanding of real world around them - the interesting

properties of space matter energy and their interactions Engineering is the

application of objective knowledge to the creation of pians designs and

means for achieving desired objectives Technology deals with tools and

techniques for carrying out the plans

Construction Technology

Basic design and construction topics which include both field and office

activates which facilitate problem definition evaluation solution and

communication ie design electives electrical equipment estimating

formwork mechanical quantity surveying rigging scaffolding scheduling

shop drawings site planning surveying takeoff utilitiesfl9

Construction industry undoubtedly is the backbone and propelling force

behind our progress It has the potential to contribute to peoples lives in

many ways This needs high skill dynamic leadership broad vision great

courage latest technology and communication system

Modern science and technology have provided many useful tools like

computers~CPM-PERT-most productive and efficient machines financial

management procedures and many others But all these become redundant

and unproductive when these sophisticated and efficient tools are worked

by green and inexperienced hands who lack the basic ingredients of work

culture dedication and courage and people who are not imaginative and

innovative

7

22 Construction technologies on the basis of labour and equipment

Construction technologies can on the basis of their content of labour and

equipment be classified as

o Equipment Intensive

o Labour based and

o Labour Intensive Technologies

The choice of the technology may affect the overall cost the overall

duration of the construction and the overall quality of the asset Some

works allow only one type of technology while others can be done in

various ways Graphically equipment intensive labour Intensive and labor

based technologies are shown in below

Potential shift in labour contents by using labour-based methods

221 Equipment Intensive Technology

Equipment intensive technology is defined as the combination of labour and

equipment In which most work is done by labOUHeplacing equipment

supported by a small labour force Although the technology might be

appropriate in circumstances with high wage levels low labour availability

and high skill levels its application is often ineffective at local level where

individual projects are relatiVely small and dispersed over a large

geographical area

8

222 labour Intensive Technology

To avoid a common misconception it is important to distinguish between

labour basedmethods and labour Intensive methods In contrast with labour

based technology labour intensive approaches seek to maximize

employment with a minimum use of mechanized equipment often at the

expense of cost and quality

223 labour BasedTechnology

In selecting the most appropriate technology it is however important that

irrespective of the type of technology resources is used efficiently quality

standards are maintained and time limitations are observed For these

reasons labour based technology has been developed to maXimize

opportunities for the employment of labour (skilled and unskilled) while

supported by light equipment under strict conditions of cost

competitiveness acceptable engineering quality standards and timely

implementation Labour based work methods are competitive only if these

conditions are met and can then provide a lasting alternative to traditional

equipment-intensive construction methods

23 Software Technologies

Normally software means the written instructions executed by some

hardware Ie Programs that are needed to run for execution and manage

the computer and those which are used to solve the problem 111 The

Software technologies have three subdivisions which are

bull Manpower (Humnware)

bull Information (Infoware)

bull Organization (Orgaware)

231 Manpower (Humnwere)

We know manpower (humnware) is the person-embodied component of

technology 111 For construction works require different types of personal but

most of them require technical background Different disciplined engineer

site engineer supervisor foreman rod binders mason skilled labour helper

9

carpenter sanitary technicians electrical technicians and other personal are

the humnware

Productivity in construction IS often broadly defined as output per labor

hour Improvement of labor productivity should be a significant activity in

building construction In construction works vigorously pursue the efficient

utilization of labor So improvement of personnel related to this field is a

vital factor of construction industry

232 Information (Infoware)

Information IInfowarel is usually the document-embodied form of technology

[11 This inciudes the specifications market database for materials theories

charts database drawing codes books journals catalogs and other

documents Requisition and supply management work(s) are also includes in

infoware Infoware constitute a crucial part of construction industry For

construction works every step is related to infoware Proper constructions

need accurate material specification guided by the code(s] Proper

information is the key factor of any construction project

233 Organization (Orgaware)

Within a frame work of the Organization (Orgawarel Manpower

(Humnware) Information (Infoware and Hardware technologies work 111

Organization techniques principles practices and arrangements that govern

the effective use of technology by humnware This includes construction

planning project management QC safety RampD

Organizational systems play the key role in construction industry Both the

success and failure of construction works widely depends on organization

An organization system includes Organization structure organization design

human resource poliCY and practice organization Culture work stress etc

Common organizational structures available in construction industries are-

bull Project organization

bull Matrix organization

bull Line and staff organization

10

24 Hardware Technology

Modern construction especially for large projects has grown in complexity

due to size cost and speed of construction Construction equipment is an

important resource and its planning assumes vital importance With the

rapidly changing technology both in design and construction areas

contractors are now shy of making heavy investment in heavy equipment

New innovation of construction equipment change the older method of

construction method and resultant is quicker and economic construction

Sometimes whole system is enhanced by new innovation Such as two

technological developments namely lilt and modern metal frame removed

the prevailing limitations on the height of the buildings Hardware is object-

embodies form of technology 111 such as Construction

equipmentmachineries all type of materials appliances computer paper

printer

The selection of appropriate construction equipment often affects the

required amount of time and effort and thus the job-site productivity of a

project It is therefore important for site managers and construction planners

to be familiar with the characteristics of the major types of equipment

Various types and important works are involved for construction Industry

Such as excavation loading compaction and grading drilling and blasting

equipment lift and erecting machineries mixing construction tools and

other equipment Different types of work require different type of hardwareand technology

11

Selection of most suitable and available equipment for a particular project is

a frequent problem for contractor Owner contractor and even the engineers

of our country are going for traditional method and material Sometimes due

to old technique and traditional material huge financial loss is the result

Money spent for equipments need to be considering as an investment

which can be recovered with a profit during the useful life of the equipment

241 Excavation

Types of equipment which are used to excavate earth and related materials

are known as excavator Excavation equipment includes the following

machines

1 Power shovels

2 Backhoes

3 Draglines

4 Clamshells and cranes

5 Trenching machines

6 Wheel-mounted belt loaders

Craneshovel consists 01 three major components

bull A carrier or mounting which provides mobility and stability for the

machine

bull A revolving deck or turntable which contains the power and

control units

bull A front-end attachment which serves the special function in an

operation

The type of mounting for all equipments Ihardware) in the above figure is

referred to as crawler mounting which is particularly suitable for crawling

over relatively roughed surfaces at a job site Other types of mounting

include truck mounting and wheel mounting which provide greater mobility

between job sites but require better surfaces for their operation The

revolving deck includes a cab to house the person operating the mounting

andor the revolving deck In the above figure a crane with hook clamshell

[Fig2-1 (f)L drag line [Fig2-1 (c)] bac khoe shovellFig 2-1 laI(b)L pile

driver[Fig2-1 (d)] and other excavation equipment are shown

A tractor consists of a crawler mounting and a non-revolving cab When an

earth-removing blade is attached to the front end of a tractor the assembly

is called a bulldozer When a bucket is attached to its front end the

assembly is known as a loader or bucket loader There are different types of

loads designed to handle most efficiently materials of different weights and

moisture contents

Scrapers are multiple units of tractor-truck and blade-bucket assemblies with

various combinations to facilitate the loading and hauling of earthwork

Major types of scrapers include single engine two-axle or three-axel

scrapers twin-engine all-wheel-drive scrapers elevating scrapers and push-

pull scrapers Each type has different characteristics of rolling resistancemaneuverability stability and speed in operation

242 Compaction and Grading

Compaction grading and soil stabilization are the works of same category

and these are interrelated Many SOilsare subject to differential expansion

and shrinkage when they undergo change in moisture content If pavements

are to be constructed on such soils it IShighly desirable to stabilize them to

prevent or reduce the change volume in order to protect the pavements from

excessive damages

Stabilizations may be applied to a soil In its natural position or as it is placed

in a fill Also stabilization may be applied to the sub-grade sub-base or

base material

14

Some methods of stabilization are

L Blending and miXing heterogeneous soils to produce more

homogenous soils

bullbullbull Incorporating hydrated lime into soils that are high in clay content

bullbullbull Blending asphalt with the soil

t Mixing Portland cement with the soil

t Incorporating various types of slats into the soils

4 Incorporating certain chemicals into the soils

t Compacting the soils thoroughly after they are processed

The function of compaction equipment is to produce higher dense soil

mechanically The basic forces used in compaction are static weight

kneading impact and vibration The degree of compaction that may be

achieved depends on the properties of soil its moisture content the

thickness of the soil layer for compaction and the method of compaction

The function of grading equipment is to bring the earthwork to desired shape

and elevation Many soils are subject to differential expansion and shrinkage

when they undergo changes in moisture content Many soils also move and

rut when subjected to moving wheel loads If pavementsbuildings are to be

constructed on such soils It is usually necessary to stabilize them to reduce

the volume changes and strengthen them to the point where then can carry

the imposed load even when they are saturated

Major types of grading equipment include motor graders and grade trimmers

The former is an all-purpose machine for grading and surface finishing the

latter is used for heavy construction because of its higher operating speed

Many types of compaction equipment are available including the following -

Towed Sheepsfoot [Fig2-2Ia)L Grid Roller [Fig2-2(b)L Self-Propelled [Fig2-

21c)) Segmented Steel Wheel Roller[Fig2-2(dll Self Propelled Tamping Foot

243 Drilling and Blasting

Drilling operation used by the construction and mining industries to drillholes in both rock and earth The task of rock excavation includes looseningloading hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling and blasting

Rock excavation is a risky and hard task ReqUire special equipment andmethods for this operation The degree of difficulty depends on physicalcharacteristics of the rock type which to be excavate Grain sizes planes ofweakness weathering brittleness and hardness of rock strata are the vitalfactors of rock excavation The task of rock excavation includes looseningloadlllg hauling and compacting The loosening operation is specialized forrock excavation and is performed by drilling blasting or rippling

Major types of drilling equipment are percusSion drills and rotary-percussiondrills A percussion drill penetrates and cuts rock by impact while it rotateswithout cutting on the upstroke

Common type of percussion drills includes a jackhammer which is hand heldand others which are mounted on a fixed frame or on a wagon or crawl formobility A rotary drill [Flg2-3(bJJ cuts by turning a bit against the rocksurface A rotary precesSion drill combines the two cutting movements toprovide a laster penetration in rock

Blasting is performed to loosen rock in order that it may be excavated orremoved from its existing position Blasting requires the use of explosivesthe most common of which is dynamite Generally electriC blasting caps areconnected in a circuit with insulated wires Power sources may be powerlines or blasting machines designed for firing electriC cap Circuits Alsoavailable are non-electrical blasting systems which combine the precisetiming and flexibility of electric blasting and safety of non-electricaldetonation

Tractor-mounted rippers are capable of penetrating and prying loose mostrock types The blade or ripper IS connected to an adjustable shank whichcontrols the angle at the tip of the blade as it is raised or loweredAutomated ripper control may be Installed to control ripping depth and tipangle

In rock tunneling special tunnel machines equipped with multiple cutterheads and capable of excavating full diameter of the tunnel are nowavailable Their use has increasingly replaced the traditional methods ofdrilling and blasting

244 Lifting and Erecting Equipment

Liftmg and erecting equipments are used to 11ftloads and to facilitate theerection of steel building frames

Derricks are commonly used to lift equipment of materiais or building

construction A derrick consists of a verticai mast and an inclined boom

sprouting from the foot of the mast Guys hold the mast in position or stiff

legs connected to a base whiie topping lift links the top of the mast and the

top of the inclined boom A hook in the road line hanging from the top of the

inclined boom is used to lift loads Guy derricks may easily be moved from

one floor to the next in a building under construction while stiff leg derricks

may be mounted on tracks for movement within a work area

Horizon boom type tower cranes are most common in high-rise building

construction Inclined boom type tower cranes are also used for erecting

steel structure

245 Mixing

Mixing concrete by hand is expensive In labour and it IS therefore not

surprising that mechanical mixers have been general use for a great many

years

The object of mixing is 10 coat the surface of all aggregate particles with

cement paste and to blend the entire ingredients of concrete into a uniform

mass this uniformity must furthermore not be disturbed by the process of

discharging from the mixer In fact the method of discharging is one of the

bases of classification of concrete mixers Several types exist In the tiltmg

mixer the mixing chamber known as the drum is tilted for discharging In

the non-tilting type the axis of the mixer is always horizontal and discharge

is obtained either by inserting a chute into the drum or by reversing the

direction of rotation of the drum or rarely by splitting of the drum There are

also pan-type mixers rather Similar in operation to an electric cake-mixer

these are called forced action mixers as distinct from the tilting and non-

tilting mixers which reiy on the free fall of concrete in the drum

19

In any mixer It is essential that sufficient interchange of materials between

different parts of the chamber takes place so that uniform concrete is

produced

On a site there is often a tendency to mix concrete as rapidly as possible

and it is therefore important to know what is the minimum mixing time

necessary to produce a concrete uniform in composition and as a result of

satisfactory strength

Concrete mixers are used to mix Portland cement sand gravel and water in

batches

There may be occasions when concrete has to be mixed by hand and

because in this case uniformity is more difficult to achieve particular care

and effort are necessary

A truck mixer refers to a concrete mixer mounted on a truck which is

capable of transporting ready mixed concrete from a central batch plant to

construction sites

246 Construction Tools and Other Equipment

Concrete can be economically pumped at the rates 15 to 200 ydhr for

horizontal distances 300 to 3000 ft and vertical distances 100 to 500 ft

without staging [11

The pumping of concrete of is especially advantageous in placements that

are physically difficult to approach with ready-mix trucks and show best

economy in the range of 20 to 80 ydhr

Air compressors [Fig2-4(al] and pumps [Fig2-4(dl] are widely used as the

power sources for construction tools include drills hammers [Fig2-4(bll

grinders saws wrenches[Fig2-4(clj staple guns sandblasting guns and

concrete vibrators Pumps are used to supply water or to dewater at

construction sites and to provide water jets for some types of construction

Vibrators are used to eliminate entrapped air Of the several types internal

vibrators perhaps the most common one External vibrator is rigidly clamped

to the formwork resting on an elastic support so that both the form and

20

concrete are vibrated Vibrating table can be considered as a case of

formwork clamped to the vibrator instead of the other way round but the

principle of vibrating the concrete and formwork together is unaltered

Besides these surface vibrator used for flat plate electric hammer can be

used as a surface vibrator when fitted with a bit having a large flat area A

vibrating roller is used for consolidating thin slabs

247 Choice of Equipment and Standard Production Rates

The selections of the appropriate type equipment or machines tor

construction often affect the required amount of time and effort and thus

the job site productivity of a project Equipment size determination is also a

very important task for construction Oversize equipments are expensive as

well as consume more time to handle It is therefore important for

construction planners to be familiar with the characteristics of the major

21

types of equipment most commonly used in construction Construction

planners also have to know the sources of construction equipment

Contractors and users of construction equipment frequently concerned with

a decision as to whether to purchase or rent (lease) an equipment Under

certain conditions it is financially advantageous to purchase whereas under

other conditions it is more economical and satisfactory to rent it

248 Building Materials

In recent times some of the important technological breakthroughs in

materials are stabilized soil lime-pozzolana mixes sand-lime bricks fly-ash

bricks clay-fly ash bricks gypsum boards wood-wool sheets plastic

products in utility service ready mix concrete non-shrink grout for machine

foundation super-plasticizers Ferro-cement and other materials Different

types of composite construction are also in very advance stage

In the field of concrete technology also some advances are happened such

as light weight concrete radiation shielding concrete polymer concretes

fiber reinforced concretes super plasticized concretes gap graded concrete

tenser-polymer reinforced concrete roller-compacted concrete ultra high

strength concrete improved techniques in pre-stressing prefabricated

construction and other some remarkable matenals

In low cost housing a number of developments have taken place and

following new techniques are being adopted for reduction in cost These arestone block masonry pre-cast brick panel roofing pre-cast RC channel

roofing ferro-cement tank use of secondary species of timber particle

board lor shutter doorswindows fly ash-lime-gypsum bricks for making

walls pre-cast RCC frames for doors and windows Pre-cast RC lintel (thin]

lower ceiling heights PVC pipes for water supply stabilized soil cement

base floors magneSium oxy-chloride flooring fire retardant treatment of

thatch asphaltic roofing etc Brief descriptions of some of those materials

are below-

22

249 Construction Automation and Robotics

Recent advances in robotic technology and the related experience In

manufacturing industries suggests that greater automation maybe extremely

beneficial for constructed facilities In addition construction in hazardous

environments (not approachable) may be greatly expanded by the use of

construction robots

There are several means by which construction automation and robotics

might repay the additional equipment and development costs associated

With high technology investments First robotics offers opportunities for

extending the scope of practical construction activities into hazardous

environments including outer space nuclear reactors or undersea

construction Even standard construction sites represent hazardous

environments as suggested by the large number job industrial accidents

associated with construction Second robotics may permit the practical

introduction and broader use of nonhuman senses and capabilities on

construction sites

KaJimaCompanys reinforcing bar placing robot can carry up to 20 bars and

automatically place these bars in pre-seiected patterns in both floors and

walls The equipment has achieved 40 to 50 savings in labor and 10

savings in time on several Japanese projects 131

A wall climbing robot called RM3 for tasks such as video inspections of shiphulls gamma-ray inspection of structural welds and high-pressure washing

painting shot-blasting and barnacle removal 131

CHAPTER 3

CONSTRUCTION INDUSTRY IN BANGLADESH

31 Introduction

The contribution of construction industry is quite significant in the national

economy but its existence is absent from the national economy plan

Recently government has made policy considering this sector as an industry

GDP Contribution of construction industry was 606 In 1991-1992 and 619

over the period 1996- 1997 Agriculture sector contributes maximum of

GDP Construction sector contribute about 20 of agriculture sector GDP

which is a remarkable role in Bangladesh economyI1

The construction Industry of Bangladesh comprises of a large number of

predominantly small firms The same can be seen to be true for most other

countries

The actual structure of the industry is not possible to measure as there are

no published papers on the total number of firms There are some 25000

nos of local contracting large medium and small categorized firms

registered with the government agencies with a varying range of financial

capacities [16]

In building construction sectors larger firms are capable to construct

concrete highrise building 30 storied Bangladesh Bank Bhaban 20 storied

Bangladesh Secretariat 20 storied Sena Kalyan Bhaban Building 20 storied

lOB Shaban and many other bUildings are the evidence of the ability to

construction of high rise concrete-building While high rise steel structures

are not yet familiar in Bangladesh but recently a number of high rise steel

structure are under construction In other sector such as bridge roads gas

pipeline electricity supply dam sluice-gate etc are implemented by

international contractors and joint venture companies (foreign and local

firms~ In 1990-91 the construction industry employed 105 and in 1995-

96 183 (statistics 97~ of total labour force In other statistics showed

that the constructing firm employs 20 lacs peoples If each family comprise

24

of four members so total 80 lacs people (615 of total population of the

countryl are dependent on the construction industry for their living The

economical and political significance of the industry ISeven greater than this

figure suggest as it captures the major part of the national investment

About 46 of the total construction labour force are involved in building

50 in construction repair and maintenance of roads and bridge works and

4 are involved in construction repair and maintenance of other activities

16]

Some domestic contractors in the building sectors have access to overseas

market but local contractors are less capable of competing with the foreign

companies due to variety of grounds -

(a) Very Less initiative from the Government to improve the capacity of the

local contractors

bull Easy policy for credit system for construction industry

bull To provide plant machinery hire facilities

bull Skill and manpower development through training

(bl Policy of the rules and conditions of the donor agencies for foreign funds

According to PWD to solve the housing problem 709131 units of houses

are required to construct in every year [15] So it indicates that Bangladesh

has a serious housing problem

12 to 15 millions people now lives in Dhaka city Dhaka the capital of

Bangladesh is now the city of construction Though yearly requirements in

the city is about 65000 housing but all public and private sector together

produce 25000 housing units in a year Percentage of leaving in slums and

squatter settlement is about 30 percent It would take at least 600 billion

taka which IS five times the entire ADP budget of the country to

accommodate house for the above-mentioned population Very little areas

are found in cities which are not occupied by building Every place in the city

is already filled up or construction of building process is ongoing But the

utility service and other facilities for community are not well thought-out

But according to government rules facilities shall be accommodate first

25

before any type of building construction Unfortunately community facilities

including simple parking facilities are still absent for the many new

constructing building in Dhaka city

32 Some large Constructions in Bangladesh

It is very difficult to identify which one is large construction of a country

because of project diversity In Bangladesh there are numerous

constructions many of them are significant in various aspects Although

functions and aesthetic are different of them they accomplish different type

of requirements Following are the some prominent constructions which

indicate Bangladesh building construction industry is fully capable to

construct any type of Building

Equipments used for construction of national assembly building were tower

33 Constructions in Bangladesh Using Pre Fabrication

Prefabricate construction not yet accepted widely in Bangladesh Scenario of

developed country in this respect is totally different Even In Malaysia

Thailand Indonesia India and many other developing countries scenery is

closed to developed countries Prefabricate construction require customize

construction or a huge no of similar type productions Precast units which

normally used in Bangladesh are -

bull Tiles and mosaic

bull Low cost toilet rings and others precast accessories

bull Prestressed precast electric pole

bull Precast column for boundary wall

29

the study on availability

of indigenous materials in

bull Precast slab for surface drain

bull Precast slab for foot path

bull Precast railing and ornamental column

bull Precast lintel

bull Precast pipe for water supply and others

bull Railway sleeper

bull Road divider

In the context of Bangladesh RampD activities are yet to be worthy InBangladesh uHouse and Building Research Institute was established in the

year 1977 with the following objectives -

1 To take technical and scientific studies and research on

various problems of constructions and building materials and

to evolve housing and building technology appropriate to the

requirement and suitable for socia-economic condition of the

country

2 To specifically emphasis on

development and utilization

construction

3 To promote better uses of building materials particularly

commonly used materials improvements methods of learning

and designing of construction works and maintenance

4 To train research personnels and technicians for the purpose

out its research activities

House and Building Research Institute time to time tried to introduce someprecast module Such as -

bull Ferro cement tank

bull Precast Ferro cement channel for roof and floor

bull Prestressed concrete hollow slab for roof and floor

bull Prestressed concrete micro pile

30

bull Precast Ferro-cement folded plate for roof

bull Precast Ferro-cement L panel for inclined roofing

bull RCCdoor and window frames

Between all type of innovation only Ferro cement tank (400 gallon consisting

of cement mortar on wire mesh) is widely used mainly in Dhaka city As

bigger size is not possible with Ferro-cement Its use is limited

Above all precast construction scenario is very poor in Bangladesh This

indicates construction technology not yet advance in Bangladesh in this high

tech era

34 Humnware Infoware and Hardware in Bangladesh

341 Humnware

For construction technology humanware includes labour technicians

engineer and other persons In some way they are related to construction

industry In Bangladesh expense for humanware is cheaper with respect to

other countries because of low wages lin Bangladesh Taka 125 per hour

and for ordinary labour in UK pound6) So utilization of man power through IT is

a great opportunity for construction sector of Bangladesh But unfortunately

we are far way from proper utilization of this huge no manpower

Development of Human resources is in very preliminary stage By generating

employment and working environment general employment conditions need

to be improved Wage systems must be developed and made transparent so

as to give proper remuneration according to qualification and technical skill

It is extremely necessary for the skilled workers to pass their skills on and to

train personnel able to respond to future technological changes Professional

training centers and methods must be developed and be efficiently exercised

upon

In Bangladesh most of the cases we make out unskilled humnware which is

unexpected in this high tech era Also in most of the cases they are

uneducated Due to unskilled and uneducated labour construction qualities

31

are not normally as per requirement Also due to unskilled labor excessive

time is requiring in most of the cases

In Bangladesh labours are mainly trained-up by on-job training In many case

they are habituated from paternal side by born Though some training

institutes exist around Dhaka city but they are certificate-based institute

These institutes deal only overseas job findings peoples

342 Infoware

Infoware IS usually the document-embodied form This includes the

software design specification materials specifications theories charts

database drawing design and others activities Use of software in

Bangladesh for the purpose of analysis and design are in satisfactory leveL

Although most of the organizations are now analyze and design by some

standard software but a big amount of engineers are not stili away from this

Orgaware lOrganization) represents the structural framework of a

technological system and it includes for example the organizations for the

RampD the production the marketing the corporate planning etc It is needed

to produce certain goods and services Within the framework of theorgaware the other technology components work [1]

Most of the organization in Bangladesh is now using computer and software

for different type of works Some organizations are using for analysis and

design some for planning purpose some as a management tools and some

one for data processing and accounting In someway organizations ofBangladesh are taking this technological advantage

In Bangladesh some organizations are doing a number of remarkable works

excellently They are creating photo realistic rendered architectural

perspective models of 3D exterior and Interior elevation and layout

rendering services 3D animation They are also creating architectural fly-by

and walk-through simulations for interactive presentation or TV quality

advertisement GIS works are also done by these organizations

Some of organizations are also working with foreign organizations Mainly

different type of data entry is their main works which are mainly data

conversion rom one format to another Such as conversion from portabledocument format (pdf) to Word processing format (docl hand sketch

J3

bull

conversion to digital drawing (dwg etc) format some modification of

drawing ete The difficulties of our organizations are for any types of

business they require an overseas office This is a very big problem for

entrepreneurs of data exchanging business

344 Hardware

In Bangladesh hardware use of construction industry is not in a suitable

level Moreover specifically modern construction equipment J technology are

not utilizing in Bangladesh most of the cases Only in a few sector such as

deeper excavation in highway construction a few no of building works are

done by modern equipments but in other sectors modern equipment are

ignoring by Bangladeshi construction industry Computer based hardware

widely using in Bangladesh as computer and some computer related

hardware are reasonably priced for middle class people

For construction projects require modern management which is based on

personal computer (PC) In Bangladesh computer based project management

is not yet popular in construction industry Only some foreign aided

government project has some activities on this but also up-to proposal level

only Truly computer based project management in construction sector not

yet Implemented in Bangladesh This is limited to some Gantt chart and

critical path draw works But hardware based computer management easily

save both money and time Probable cause for which not yet go for

computer based project management listing below -

Labours and technicians are illiterate

From Government side there are no plan to facilitate these sector

even in Government project

Our engineers backgrounds are also not upto that extent and

also they are not interested to go for such type of management

CHAPTER 4

TECHNOLOGY ON EXCAVATION amp RCC OF BANGLADESH

Nowadays building construction mainly equipment intensive works allover

the world that is depend on modern technology Similarly construction

industry of Bangladesh going away step by step depends on technology

Technological application sophistication quality etc are different in country

to country but at every steps of construction industry including construction

industry of Bangladesh totally depends on construction technology For

excavation loading compaction grading drilling lifting erecting mixing

and other purposes require some construction hardwareequipment and there

technological approach is different Not only for equipment but in every

steps of construction process depends on technological involvement In this

chapter mainly discussed the effect on excavation due to equipment

intensive and labour intensive works Also for building construction the

effect of alternate combination of material use

41 Technology in Excavation

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground This foundation is mandatory for

every structure ThiS is the reason of start of excavation technology which

is an earliest form of civil engineering construction This technology is used

for excavate earth of foundationbasement Excavated soilrock usually

dumps in other places which is known as loading Many construction

industry of Bangladesh Excavator and Loader are mainly using for

excavation works But use of excavator is mostly Dhaka based In other

places of the country except Dhaka city excavation works are done by

manually which is very unlikable in this high tech era Even in Dhaka city

many excavation works had been done by manually Such as 18 storied

New Market City Complex building with two basements (adjacent of Dhaka

new market) 14 storied CRP building project with two basements at Mirpur-

35

14 Dhaka A few but in some projects huge volume of soil was excavated

manually Excavation operations 01 these many projects are done by

manually because 01 availability and low-priced labor In this chapter try to

focus why this technology (excavator not used in most of the cases

In many project of Bangladesh excavation operation are done by manually

because 01-

Soil Characteristics - Comparatively solt layer 01 earth exists all

around Bangladesh

raquo labour (Humnwarel - labour costs are cheap and available

Non-availability of equipment (Hardware) - Modern equipment

cost is very high for which it is not pOSSiblelor contractor to

buy excavator and other heavy equipments lor a singie project

gt- No and size of the Job - As no 01 projects limited and also

areas of a single projects are not big Use of Excavator and

loader are not economically viable

Rental organization - Renta I organization not yet developed

widely and systematically Above all limited rental organization

and their higher charges of hardware

Topography Most of the lands in Bangladesh are plain So

labors can work comfortably

lacks of technicians - lack of skilled technicians are one of the

reasons to avoid new technology

Time - Peoples of Bangladesh are not anxious about time

Utilization of time is very important lack 01 this awareness is

one 01 the reasons of avoiding tendency of new technology for

excavation

)- Space constrains - Particularly in Dhaka city buildings are not

build in well planned way but very haphazard So in many case

movement 01 excavator is very difficult and in some cases it is

impossible to work due to space constrain

36

bull Weather and Temperature - Luckily most of the seasons are

suitable for labour works Nature is very fever for manual

labour except very little lime through out the year So not

need to take extra precaution lor climate

gt Dumping area - Some time huge amount of dumping is not

possible For that reason avoiding tendency to new technology

of excavation

bull Transportation equipments - Some times transportation of

dumping is not viable and In that type of case manual labour is

preferable

411 Preliminary Stage

The substructure or foundation is that part of a structure which is usually

placed below the surface of the ground and which transmits the load to the

underlying sailor rock As the foundation normally placed below the ground

excavation is must and should be done first for any type of construction

work

More or less for every construction works need excavation some times

these are shallow and some times it is deep Due to basement construction

of high-rise buildings need massive excavation This may need up to three

four months If excavation works are done by manually a huge no of labors

will engage their and require more time

Considering employment it is solVing a substantial social problem like our

developing country by means of giving a large no of employment

opportunity Therefore out side the urban area manual excavation may be

permissible due to solving unemployment problem This might be plaYing a

significant role like our developing country to solve the problem Social

problem from society But owners always try to solve the problem from the

economic view which will figure out later on this chapter

But the scenario in urban areas like Dhaka city is different Dhaka has

already become a mega city with more than ten million inhabitants and its

population is projected to reach 16 million by 2015 which would make it

the worlds seventh most populous city This rapid growth is visible all

37

around the city by constructing new buildings But the citys infrastructure is

not keeping space with the influx of population Transport environment of

Dhaka city may be a clear example with increasing traffic congestion and

delays The ability of Dhakas transport system to sustain economic growth

and reasonable quality of life has been declining steadily

In such a poor situation if we dont use machinery equipment everyday

congestion situation of Dhaka city will escalate due to longer timerequirement of excavation

Already it is an established fact that construction works of Dhaka city is one

of main reasons of traffic congestion To overcome this awlul situation

particularly in the city areas we must have to adopt modern technology in

excavation purpose This will help to reduce construction time money

traffic congestion and other redundant situations

412 Time and Seasonal Effects on Construction

Time

In Bangladesh construction management going on very preliminary stage and

still they dont think time is a vital factor for any project But everyone is

aware the fact money has a time value Thousand Taka today is worth

more the Thousand tomorrow This lact is vividly reinforced when themonthly charge bills are examined This added charge amounts to rent on

the money that is owed and is termed interest

Besides these we know fixed costs are directly related to time variable andother costs are also similar effect ie if time span of a project is longer then

fixed cost will be more and similarly true for all other costs So time span ISa vital factor for any construction project

Again for any project there is a breakeven point which also dependents on

time If construction period is more than the estimated time timerequirement to reach break even will be more

BeSides these there is a possibility to come other competitors due to delay

of construction and sometimes it may become an unprofitable project forever in this competitive market

38

If we Consider revenue side what we see - Suppose a 10 storied office

building spaces are 12000 sq-ft and rent is 501 = Taka per sq-ft ie per day

revenue is 20 Lac Particularly this type of project per day revenue loss will

be a big amount if the construction not timely finish This is unexpected for

any organizationlsJcontractorls)

Season

In many cases for foundation purpose deep excavation is required

Sometimes need shore pile to protect adjacent soil Shore pile is essential

when permanent structure exist adjacent project site As shore pile is a

temporary work in many cases it designs less cautiously Result is that

shore pile failures are a common type of failure in Dhaka city at every year

It is occurred mainly in rainy season due to rainfall If the contractors are

finished their foundation works before rainy season most of the time they

can avoid these repetitive shore pile failure situations

On the other hand in many cases owner of adjacent structure goes to the

court when contractor goes for deeper excavation for their safety and

compensation if shore pile failure occurs Also for shore pile failure delays

the project ie more time consume for project and more money expenses

due to delay or to pay compensation Sometimes it becomes a crucial factor

for the project and as a result of big economical loss for that project Such

type of big economical loss easily can avoid by proper time scheduling ie

should be complete before expected rainy season in case of deeperfoundation works

39

413 Cost Analysis and Result

Assumption made for cost and analysis are follows-

1 For Manual 1000 eft of excavation work (PWDStandard Rates)

al For initial lead of 100_ON and lift of 5_ON

i) Ordinary labour cost Tk 088 per cIt

b) For each additional lift of one loot beyond 5-0 and upto 10_ON

i) Extra ordinary labour cost Tk 004 per cit

c) For each additional lilt of one foot beyond 10-0 and upto 15-0

il Extra ordinary labour cost Tk 006 per cit

d) For each additional lift of one foot beyond 15_ON and upto 20_ON

i) Extra ordinary labour cost Tk 008 per eft

e) Extra each additional lead of 100-0

il Extra ordinary labour cost Tk 014 per eft

2 For Excavator

f) Initial rent Tk 9000000 for upto 10 days

il Extra charge Tkl0OOO00 per day

iii Excavation capacity 10000 eft per day

3 Enough labour Force

gl Enough labour force can be engaged so that there will not be any

significant difference in excavation between these two methods

42 Design and Specifications

421 Material for Building Construction

Wood of course was the only material used by early builders that had more

or less equal tensile and compressive strength Early builders are also

depends on stone brick surki and lime After innovation of reinforced-

concrete and steel previously used material are replaced by concrete and

steel Concrete with reinforcement radically change in the field of building

construction technology After that steel play the vital role and contribute to

build high rise building worldwide though Bangladesh is far from that type

high rise building But recently numbers of steel bUilding are in the process

of construction and we are expecting remarkable progress will be shown

within couple of years Nowadays wood has been relegated largely to

accessory use during construction to use in temporary and secondary

structures and to use for secondary member of permanent construction

Though both concrete and steel are the two most commonly used structural

material worldwide in Bangladesh mainly concrete are common item of

building construction Recently some industrial buildings are constructed by

structural steel Builders in Bangladesh are now reali2ing that steel is also a

competitive and effective material for building construction But they are

going forward very slowly for steel structure

Selection of structural materials must be selected on availability of materials

Also depends on corresponding skill labour relative costs wage scale and

the suitability of the materials for particular structure

In Bangladesh currently carrying out research into rice straw and husks

which are a by-product of major crop of Bangladesh but have already

encountered problems with the strength of the rice straw while fit best rice

45

husks can be regarded as filler and may not contribute significantly to the

tensile strength of earth-mix bricks

Idea of including waste material from the countrys vast jute industry to use

as a binder in the bricks and not merely as rubbish to be burnt

And finally that the integrity of earth-built buildings may be considerably

strengthened and improved by applying simple low-cost principles to the

Internal strengthening structures - mostly tied bamboo frameworks

4211 Material in Bangladesh

Any material which has got application in engineering construction is termed

as engineering material Stones bricks concrete bricks lime cement surki

sand concrete iron steel ferrous alloys non-ferrous metais and alloys

timber timber products aluminums bamboos soils bituminous materials

glass plastics paints varnishes rubber tiles granite marble etc are

commonly used in Bangladesh

Among them major construction materials are now producing in Bangladesh

though maximum raw materials are imported outside from Bangladesh

Though cement raw materials like gypsum and clinker are importing from

outside of country the total cement producing capacity now is more than

countrys per year requirement and quality of cement is standard as per

specification But reinforcement quality is not yet reached to standard level

It is very serious problem for construction industry of Bangladesh

46

4212 Reinforcement

Steel is known as black copper in early ages Iron and steel developed over

2000 years ago It was Henry Bessemer who was especially interested in

good quality steel making for big canons He was the first to produce low

carbon wrought iron In Bangladesh steel also used as reinforcement in many

years before It is difficult to say when and where first time used steel

reinforcement

Concrete reinforcement bar are usually of two types

bull Deformed bar and

bull Twisted bar

Below are the specifications for two types of reinforcement bar-

Table 4-5Steel GradeGrade 40Grade 60

ASTM 616 specifications for Deformed barYield Stre9th (psi Ultimate Stren ths (psi)40000 (minimum) 70000 (minimum)60000 (minimum) 90000 (minimum)

Grade 40 and Grade 60 both type of reinforcement are frequently used InBangladesh for building construction In Bangladesh normally steel areprocessed by the follOWingmethod

(i) Induction furnace melting and(ii) Arc furnace melting

The yearly requirement of steel in Bangladesh is 10 million ton But the

quality steel production rate is only 02 million tonyear That is remaining

08 million ton reinforcement are non-standard 1171 By which our different

construction works are building This is an awful situation of construction

sector in Bangladeshand requires immediate exemption from this situation

47

4213 Concrete

Allover the world concrete with reinforcement are the most commonly used

materials for building construction In Bangladesh it is the main structural

material using as building construction materials Concrete IS a stone like

material obtained by permitting a carefully proportioned mixture of cement

sand and gravel or other aggregate and water to harden in forms of the

shape and dimensions of the desired structure

Bangladesh is now a big cement producing country in respect to their

required capacity Statistics says yearly requirement of cement allover the

Bangladesh is 65 million tons where as production capacity of the entire

cement mill is 120 million tons That means 55 million tons surplus cement

now existing in Bangladesh One of the main reasons of this surplus is that

world top most cement producing companies are now producing cement in

Bangladesh from their factory

The properties that make concrete a universal building material are so

pronounced that it has been used In more primitive kinds and ways than at

present for thousands of years probably beginning in Egyptian antiquity

The facility with which while plastic it can be deposited and made to fill

forms or aids of almost any practical shape is one of these factors Its high

fire and weather resistance are eVident advantages Most of the constituent

materials with the possible exception of cement are usually available at low

cost locally or at small distances from the construction site

In Bangladesh normally concrete strength (cylinder strength fc) varies from

2500 psi to 5000 psi for building construction But in many case it falls to

2000 PSI On the other hand upto 8000 psi concrete was used for

construction of Jamuna Multipurpose Bridge project Also there are many

projects already finished and ongoing where usedusing more than 5000 psi

strength concrete

48

4214 Steel

In 1885 an American engineer names William LeBaron Jenny became the

creator of the modern skyscraper when he realized that an office building

could be constructed using totally different materials He chose structural

steel and incorporated it into a revolutionary system that was to make

possible the soaring office towers that now symbolize the modernmetropolis

Steel is manufactured under controlled conditions its properties are

determined in a laboratory and described in a manufacturers certificate

Thus the designer need only specify the steel as complying with a relevant

standard and the site engineers supervision is limited to the workmanship

of the connections between the Individual steel members So responsible of

contractor is more to provide proper material

Also following are some reasons normally associated with competitiveadvantages of steel over concrete

bull Construction speed particularly during periods of high interest rates

Steel frames go up more rapidly thus reducing construction financing

costs and allowing the building to generate revenue sooner

bull Availability of steel in a variety of grades and shapes that IS suitable

for economical faming of both short and long spans

bull Steel offers economical design approach for retrofit and rehab

projects Steel can be easily modified expanded or converted to suit

future needs of owners and tenants For this reason steel frame isoften referred to as a changeable frame

bull In difficult foundation conditions steel construction may result in

reduced foundation costs because of its light weight Steel frame is

normally 25 to 35 percent lighter than a concrete frame and can

permit the use of less expensive foundation systems

In Bangladesh steel building are not constructing notably Mainly some

factory buildings are constructed with steel as a structural material In

Bangladesh peoples are not serious about time which is main advantage of

steel structure like our COuntry We have to import all the steel materials It

49

also has to PV higher tax Our engineers are not interested to go for new

technology like steel structure 0 technicians oed labors pof Vtrained P fo steel construction Ultimately except time factor steel

structure is OPt very suitable for building construction of Bangladesh Very

recently a few numbers of high-rise buildings are now under construction or

under designing stages which indicates new technology are coming

4215 RCC Grading

Strength of concrete is commonly considered its most important property

although in many practical cases other characteristic such as durability and

impermeability may in fact be more important Nevertheless strength usually

gives an overall picture of the quality of concrete because strength is

directly related to the structure of the hardened cement paste

The strength of concrete of given mix proportions is very seriously affected

by the degree of its compaction It ISvital therefore that conSistence of the

mix be such that the concrete can be transported placed and finished

sufficiently easily and without segregation Following combinations of

reinforcement and concrete are considered for thiS study-

4217 Interdependence of Humnware Infoware and Hardware

For analysis and design purpose humnware infoware and hardware work as

an integrated system During design and analysis period due to different

grade and type material selection software hardware and humnware play

the vital role for alternate attempt Computer utilization in different stages

have improved capabilities for generating quality designs as well as redUCing

the time required to produce alternative designs Without help of these

technological combined services It IS almost impossible to get better and

optimistic design Thats why with the help of Humnware Infoware and

Hardware most economic type analysis and design may achieved within

short time which is almost impossible without these technological help

Manual analysis and design are most of the time assumption based a time

consuming matter and whose ultimate result is economical loss considered

to both time and material requirement

CHAPTER 5

CONCLUSIONS AND RECOMMENDATIONS

51 Discussion

In developed countries civil engineering organizations spend good amount of

money in RampD At national level the universities and other institutions

should be encouraged to undertake strategic research which aims to Improve

understanding and applications of scientific and technical know how which

in turn will provide a basis in the long run proper application of new

techniques and technologies Following are some areas very essential for

construction Industry of Bangladesh

The development and dissemination of new construction equipment and

better safety must be encouraged

Pre-fabrication and use of package materials will enhance the efficiency of

work execution by standardizing specifications and reduce the site work

volumes

The development and dissemination of all weather construction technology

will make it possible to carryon with work even under bad weather

The means of transferring information between designers and constructors

need to be improved The effective use of construction equipment

prefabricated materials and products needs to be considered

The roles and responsibilities of engineers need to be reviewed With regard

to improvements in work efficiency personnel training and strengthening the

management foundation of engineers

52 Conclusion

Excavation

Manual excavation and excavation USing excavator S to 20 ft depth) with

different land areas were studied in Dhaka city Considering labour cost and

excavator rental charge breakeven point for Sft excavation and 20ft excavation

are 19020sft and 3616sft respectively Using PDW97 standard rate of works

it IS observed that for deeper excavation excavator is cheaper than labor-

intensivemanual excavation Labor-intensivemanual excavation works may be

acceptable outside urban areas due to unemployment of labor But excavator is

economic solution in urban areas like Dhaka city

In Bangladesh excavation and loading is a labour-based works but in developed

countries its hardware-based works Further detail study based on socio-

economic environment etc may be required to introduce hardware-based

excavation work replacing manual labor in our country

Material

8 combinations of steel and concrete were studied for a six storied bUilding

Considering material cost Type- ICombination of high strength concrete 44-

ksi with high strength steel 60-ksi) is the most economic Type8 la

combination of low grade concrete 2S-ksi and low grade steel 40-ksi) is the

most uneconomic as it material costs 29 more than the cost due to the Type-

1 Unfortunately Type-8 combination is most widely used in private construction

even by the real estate developer One problem with Type- is that high

strength concrete 144 ksi concrete with 60 ksi steel) demands admixture which

also demand skilled humnware If it is not possible type 2 (36 ksi concrete

with 60 ksi steel) can be easily used without loosing Significant economy lonly

3 more cost than Type-l) Mainly Engineers may play the significant role to

convince ownersentrepreneur to accept this technological advantage and avoid

uneconomical traditional approach

53 Scope for Future Works

Similar studies may be carried out for other components of technology Inamely

different types of hardware technology humnware infoware etc)
