1.0 General Introduction

The practical training conducted by the engineering and non engineering students at the

respective industrial units related to their subjects is termed as "Industrial Training". For

example a civil engineering student requires practical exposure at the building

construction sites, road construction projects etc. The industry-institute interaction is a

need of the hour. No institute or technical board could ever boast of a perfect syllabi

scheme without the inclusion of industrial training format. The industrial training is a part

of continuous learning process. So this field exposure that uplifts the knowledge and

experience of students needs to be properly documented in the form of report, which can

be termed as “Industrial report". A properly prepared industrial training report can

facilitate the presentation of the field experience is an orderly, precise and interesting

manner, which can off course well serve as a guide to the new entrant engineers. The

purpose of industrial training as:-

1) To provide field exposure to the students.

2) To have better understanding of engineering practices.

3) To make them adapt to industrial conditions.

4) To provide opportunities to the students to handle tasks independently.

5) To help students to understand about the duties of an engineer and other supervisory

staff in an organization.

6) To make them aware with the common industrial problems.

7) To impart intensive training to the students to enable them to learn and use working of

latest field equipments machine.

10.0 STEPS OF CONSTRUCTION WORK

These are the steps which are mainly followed for the begging of construction.

1) Types of building:-First select the type of building whatever we want to construct,

depending on the need like villas, flats, apartments, penthouses, malls, industrial

buildings or group housing.



2) Site Selection: - Site for construction of building can be selected according to the

space required and whatever the area and the people demands, in accordance with the

population and bearing in mind the geographical and industrial point of view for

further development.

3) Survey: - By survey we measure all the dimensions and plot the real position or place

wherever we want to construct our structure. This includes many aspects like

financial survey, economical survey, topographical survey etc. etc.

4) Site Investigation: -By this we investigate about the type of the soil, bearing capacity

of the soil, nature of the bed, the topographical feature of the area, which in turn helps

the structural designer to design the footing for our project.

5) Architectural Drawings: - Architectural drawings are the heart to the project, which

is the master document or the copy with which we have to stick completely and do

accordingly; these drawings have all the plans and construction details about the

particular project.

6) Structure Design: - Structural Designer is that person who gives life to an

Architectural Drawing; it infuses the correct data and interpret the correct meaning

which an Engineer knows. He suggests the type of foundation, columns, beams and

slabs etc. which are needed for the construction and also provides the amount of steel

and its size.

7) Construction: - After all these steps, Construction of the proposed project starts. The

construction is done at the site in which different section is divided like Civil, Electric

and Mechanical work.

11.0 Methodology of Work



a) Site Clearance: - The very first step is site clearance which involves removal of grass

and vegetation along with any other objections which might be there in the site location.

b) Positioning of Central coordinate and layout: - The centre point was marked with

the help of a TOTAL STATION, thread and plumb bob as per the grid drawing. With

respect to this center point, all the other points of columns were to be decided so its exact

position is very critical.

c) Excavation: - Excavation was carried out both manually as well as mechanically.

Adequate precautions are taken to see that the excavation operations do not damage the

adjoining structures. Excavation is carried out providing adequate side slopes and

dressing of excavation bottom. The soil present beneath the surface was too clayey so it

was dumped and was not used for back filling. The filling is done in layer not exceeding

20 cm layer and then it’s compacted. Depth of excavation was 2.0 meter from Ground

Level. There are some points which should be kept in mind at the time of excavation:-

1. Upon identifying warning tape of any service, mechanical excavation shall be stopped

and manual excavation shall be done.

2. In areas where the trench is close to the buildings, depending on the type of

foundation of the building, shoring shall be done by planking, strutting or trench

sheets.

3. In other areas it will be stepped open excavation with battered slopes.

4. Dewatering system shall continue to run until backfilling is completed up to the level

of the natural water table.

5. Bottom of the trench shall be cleaned, free of loose material; rock projections and the

surface will be leveled and moistened uniformly before commencing compaction.

Leveled bottom surface shall be compacted as per the specification.



Fig.:-8 Excavation Fig.:-9 Layouts Marking

d) Laying of P.C.C. (Plain Cement Concrete):- After the process of excavation, laying

of plain cement concrete that is PCC is done. A layer of 100mm with projection was

made in such a manner that it was not mixed with the soil. It provides a solid base for the

raft foundation and a mix of 1:4:8 that is, 1 part of cement to 4 parts of fine aggregates

and 8 parts of coarse aggregates by weight were used in it. Plain concrete is vibrated to

achieve full compaction. Concrete placed below ground should be protected from falling

earth during and after placing. When joint in a layer of concrete are unavoidable, and end

is sloped at an angle of 30 and junctions of different layers break joint in laying upper

layer of concrete. The lower surface is made rough and clean watered before upper layer

is laid.

Fig.-10 Laying of P.C.C.



e) Raft Foundation: - At our site, Raft foundations are used to spread the load from a

structure over a large area, normally the entire area of the structure. Normally raft

foundation is used when large load is to be distributed and it is not possible to provide

individual footings due to space constraints that are they would overlap on each other.

They are often needed on soft or loose soils with low bearing capacity as they can spread

the loads over a larger area.

f) Construction of Pedestal: - As the steel of raft is laid down the reinforcement of

pedestal is started. The purpose of pedestal is to distribute the load uniformly of column

to footing. It provides the support to plinth beam and column. The size of pedestal is

greater than to column size.

g) Plinth Beam: - This is a band which provided at the plinth level, on the top of

foundation these bands are provided for decreasing the chances of uneven settlement of

structure and it also serve the purpose of damp proof course. During the earthquake these

band are responsible to hold the structure as a single unit when the ground shake. Before

the concreting of plinth beam the level of beam must be checked so that commencement

of work can be done accurately.

h) Column: - A column is an important component of RCC structure. It is a vertical

member which is used to transfer the load of super structure such as super structure, floor,

balconies, slab etc. The method of construction of column is follow:-

I. Placing vertical steel of columns: - As according to structural drawing (column

schedule) vertical bars were placed through top reinforcement of raft on the

position marked earlier (6.5) above the bottom reinforcement of raft.



II. Layout of columns: - After casting of raft again the layout of column is done in

order to check the actual position of vertical bars of columns. The layout is also

helpful to place the shuttering on actual position, so that the column should be in

proper position according to drawing (Column layout drawing).III. Bar binding and column starter: - Shear reinforcement was tied as according to

structural drawing (column schedule) up to the height determined from framing

plan. At bottom instead of making column starter a T shaped bar was weld with

vertical steel on the layout of column so the shuttering can be fixed on desired

accurate position.

IV. Formwork: - The shuttering either conventional or system is fixed around

column and plumb of this shuttering is checked out. At bottom the T shaped bars

keeps the shuttering on position and at top and middle cover blocks are fixed so

that proper cover could be provide to reinforcement. The T shaped bar at bottom

and cover blocks at middle and top ensure the straightness of vertical

reinforcement.

i) Laying of Beam and Slab: - A structural member which supports lateral load and

resist bending is known as beam. Slabs are plane structural member whose thickness is

quite small as compared to its other dimension. Slab support mainly transverse loads and

transfer them to end supports by bending action in one or more directions. The steps

which are followed for the construction of column are written as below:-

I. Fixing Beam bottom and slab formwork: - Beam bottoms are fixed along with

the vertical reinforcement of columns using a specially made arrangement called

“BEAM SUPPORTER”. Then sides of beams are fixed and then main slab’s

shuttering is laid according to architectural drawing (framing plan). The gaps are

filled and uniform horizontal platform is made to support the slab. Generally

beam bottom and slab’s shuttering is made of plywood and rests on vertical steel

pipe arrangement called “probes”. Note: All the sunken portions and sections

according to co-ordinate framing plan should be taken into consideration while

fixing the beam bottoms and slab’s shuttering. II. Laying reinforcement of beams and slab: - First of all reinforcement of primary

beams is laid and then secondary beams on a certain height above the shuttering



according to structural drawing (beam detail). After all beams are tied and are

placed on their respective position slab reinforcement is laid according to

structural drawing (slab reinforcement detail) and bar bending schedule. Cover

blocks are placed in between shuttering and slabs reinforcement. Note: All the

section should read carefully and dowel required for any section or staircase

should be placed before casting.

III. Leveling of slab: - To check exact level of slab (both bottom and top) a certain

level is marked above the finished floor level on columns bars as convenient. A

thread is tied throughout that mark on the column bars at the marked level and

level of slab (bottom and top) is measured by measuring the perpendicular length

from thread level to the top level of slab by the help of measuring tape or a

graduated bar.

g) Laying of Stair and Lift: - A series of steps or flight of steps that go from one level to

another is called stair. The form work can be made up with plywood or framing lumber.

The first step is to cut the side forms according to the drawing. Add wooden member as

bracing against the outward movement and depending on the width of stair additional

bracing should be provided at centre. Make sure that the forms are plumb and level



before proceeding further. After that concrete is prepared from R.M.C. and poured into

Frame work. Concrete should be poured from the bottom step. Once you pour it, it should

be spread evenly. Use a spade or a rod to remove trapped air bubbles. A screed board is a

piece of lumber somewhat longer than width is used for the finishing purpose. Last step is

curing, it can be done be gunny bags or by pounding method.

Lift is a vertical access that moves up and down inside a building and carries

peoples from one floor to another floor. The lift frame is made of R.C.C. and construction

method is same as other member. There is one precaution must be considered that it

should be vertical straight and leveled. The formwork should be strong enough to take the

dead load and live load during construction. It should be watertight and easily removed

after placing of concrete.

14.0 Information about Material

The various materials used for constructing and supporting the building are termed as

Building Materials. The different building materials in use such as soil, aggregates,



cement, sand and steel are to be tested before using them in building construction. The

materials which are used at site as below:-

a) Cement: - Cement is a binding material that has cohesive and adhesive property in the

presence of water. There are two type of cement is used at the site-1)OPC 43(Ordinary

Portland cement) 2) PPC (Pozzolona Portland cement).The company name is SHREE

ULTERA CEMENT. The capacity of one bag is 35liter or 50Kg bag and area is 0.3square

meter. OPC cement is used in the construction of foundation, column, beam and slab.

PPC cement is used for the finishing work like plastering, pointing and brick work.

Curing period for the OPC is 28 days and for PPC is 90 days so that’s why OPC cement

is used for structure parts. Cement is to be store in WARE HOUSE the capacity of site

ware house is 5000 bags. The rate of one bag is 260 rupees for the company.

Fig-18 Ware House

b) Brick: - An artificial masonry unit in the form of rectangular block of prepared clay is

called a brick. The main constituents of brick are Alumina, Silica and lime. The standard

size of brick is 190X90X90mm but at the site size of brick is 220X110X75mm.The site

brick is considered in Category ‘B’ which is irregular in shape and strength lies more than

75kg/cm2.The quantity of bricks in one cubic meter is 500No.The main points which

should be kept in made while laying are Brick should not construct more than 5 feet in



one day. Frog should be placed at the top face for proper bonding. It should not break

when it is fall from height of 3feet.The rate of brick is 4000rupess per 100 no.

Fig.-19 Brick Stock

c) Sand and Aggregate: - Sand is a filling material which is used in concrete, mortar and

plastering. Sand is basically consisting of small grains of silica which is formed by the

decomposition of sandstones due to various effects of weather. The sand which is used at

sites coming from Phtankoat river of two sizes-fine sand and coarse sand(lies2.36-

4.75).There is one factor which effects batching i.e. Bulking of sand. The presence of

moisture in sand increases the volume of sand. This is due to the fact that moisture causes

film of water around sand particles which results in the increase of volume of sand.

Fig.-20 Sand and Aggregate

Mix Proportion=M20 (1:1.5:3) and 18% bulk age and volume of one bag is 35 liters.

according to that volume of sand required is 70 liters but due to bulking volume of sand



required 70 x 118/100 = 82.5 liters. From we can see that there is too much effect on

volume of sand.

Aggregate are the inert material which forms the bulk of cement concrete. The

aggregate are bound together by mean of cement. The size of aggregate which is used at

the site is 10mm and 20mm.The rate of 10mm aggregate is 23.5 rupees per cubic

feet(920rupees per cubic meter) and 20mm aggregate is 22 rupees per cubic feet(780

rupees per cubic meter).There are three types of aggregate according to shape is Rounded

aggregate, Angular aggregate and irregular aggregate. The shape of aggregate at site is

angular because it provides good bonding.

d) Steel: - Steel is most commonly used as reinforcing material as tension member

because is satisfying all characteristics requirement for an ideal reinforcing material.

There are basically four grade which are available in market of HYSD group is Fe415,

Fe415D, Fe500, Fe500D, Fe550, Fe550D, Fe600. The grade which is used at the site is

500D of sizes 8mm, 10mm, 12mm, 16mm, 20mm, 25mm. Size of 8mm,10mm and 12mm

is used in slab and 16mm,20mm is used in beam and column. Due to ribs present on steel

bars, it develops good bond with concrete.

Fig.-21 Steel

The strength of grade 500 and 500D is same but the difference is only there is

elongation. 500D grade has more percentage elongation as compared to Fe500. TATA

steel has introduced Fe500D grade in market with percentage elongation of 16% more as

compared to Fe500.The rate of steel is 48000 rupees per tonne i.e.48 rupees per Kg. The

company of steel which is used at site is TATA, SAIL, and BHEL. The steel is coming in



form of coil less than 12mm which is shown in figure. As the size of steel is decrease, the

rate is increase.

e) Admixture: - Admixture is the materials which are used to improve the quality of

concrete. The admixture which is used at the is coming from STP Limited company. The

capacity of one drum is 250 Kg and rate of one Kg. is 30 rupees. This admixture is helps

to increase the setting time and maintain the strength of concrete.

Fig.-22 Admixture Tank

F) Miscellaneous: - Miscellaneous materials are those which are also important except

basic materials. There are numbers of materials which are used for construction at site

which are:-

1) Plastic pipes 2) G.I. pipes 3) Electric Wires 4) Fiber Sheets5) Bitumen 6) Water proofing7) Termite proofing 8) Fire resistance 9) Paint and Varnish 10) Glass 11) Wooden Doors 12) Chips13) Marble 14) POP

16.0 Information about Test

There are number of tests which are performed at the site on different material. The tests

which we have performed at the site are below:-



a) Slump Test: - This test is used to check the workability of concrete at site. Steel mould

is used which is in the form of frustum of cone whose dimensions are 300mm at bottom

dia., 200mm at top dia. and height is 100mm.

Observation and calculations:-

Proportion of sample = M25

Water Cement Ratio = 0.446

Slump Value = 105mm

Standard Value

Sr. No. Slump value Degree of Workability Uses at site1 Less than 25 Very Low Precast work2 25-75 Low Road pavement3 75-100 Medium R.C.C footing4 Greater than 100 High Column, beam

Result- Our sample is coming in category 4. When concrete is transported through pump

then its value should be taken more as to standard.

Fig.-23 Slump Test

b) Bulking of Sand: - The increase in volume of sand due to presence of surface

moisture up to certain extent is known as bulking of sand. The bulking of sand has

importance when batching is done by volume. Bulked sand occupies more volume than

dry sand. To compensate the bulking effect, extra sand is added. Otherwise concrete mix

becomes deficient in sand and will have tendency to segregate. The observation is as

follow:-

Observation and calculation:-



Height of loose sand = 150mm

Height of saturated sand = 144 mm

Percentage of Bulking = 4.16%

Result:- Value of bulking of sand is 4.16%. This value should not be greater than 5% as

per standard.

Fig.-24 Bulking of Sand

c) Compressive Test: - The compressive strength of a cube is an indication of the

strength of concrete. With the help of this we can check the characteristics strength of

concrete. The size of cube is taken as 15cm3. At least three specimen should be made for

testing which is to be performed at 7, 21, 28 days.

Observation and calculations:-

Proportion of concrete = M25

Cross-section Area = 15x15=225 cm3

Breaking Load = 770 KN

Compressive strength after 28 days = 34.2 KN/mm2

Result:- Compressive Strength of concrete sample after 28 days is 34.2N/mm2. Whereas

strength requirement is 25 N/mm2, hence tested sample is safe.



Fig.-25 Compressive Strength of Concrete

d) Silt Content: - Silt is a material of particle sizes between 0.002mm to 0.06mm. It is

usually found in sands obtained from natural sources such as river bed. If it is present in

excess quantity then is preventing a bond between cement and aggregate. Silt value is to

be increase more than 6% by volume. This test is to be easily performed in beaker of size

250ml.

Observation and Calculation:-

Height of sample = 150ml

Height of silt after 3 hours = 6ml

Percentage of Silt = 4%

Result:- Its value does not increase more than 6% by volume.

e) Weight of Steel: - This is a field test which is performed on steel to check wt. meter

length because there are number of impurities will be added in the materials due to

temperature variations so that its wt. will varies from the standard value. There is a

chance of corrosion and rusting over steel bar

Result:- From the result we can check most of value is matching with each other.

f) Compressive Test of Brick: - This test is used to check the compressive strength of

brick. Brick laid in building are generally under compression. The Brick are divided into

four categories Class A, B, C, and D. from this test we can examine that which type of

brick is used at site. Generally five numbers of brick are randomly selected and frog is

filled with cement mortar of ratio 1:1. Load is applied at rate of 140 kg per minutes.


Area of Brick: - 25300 mm2

Load at failure: - 19860 kg

Compressive strength: - 78.5 kg/cm2

Result: - Compressive strength of brick is 75 kg/cm2, so that is coming under Class B.

Fig.-26 Compressive Strength of Brick

g) Efflorescence Test: - This test is performed to know the presence of any alkaline

matter in the brick. Nil- there is no perceptible deposit of efflorescence. Slight- when not

more than 10% of the area of the brick is covered with a thin deposit of salt. Moderate-

there is a heavier deposit covering up to 50% of area. Heavy- When there is too much salt

in brick exceed 50%.



Result:- Our sample is coming under Slight group.

Fig-27 Efflorescence Test Fig.28 Water Absorption of brick

h) Water absorption test: - The strength of brick depends upon its water absorption

capacity. If the brick has more water absorption capacity, it will loosen its strength earlier,

because using the brick, it should, therefore, be tested for its water absorption capacity

which should not be more than 20% by weight for Ist class brick.


Weight of Sample: - 3.86 kg

Weight of Dry sample: - 3.5 kg

Water absorption:- 10.1%

Result- The water absorption of brick sample is 10%. It should not be increase 20% for

Ist class brick.

i) Grading of Aggregate: - The art of doing gradation of an aggregate as determined by

sieve analysis is known as grading of aggregate. The principal of grading is that the

smaller sizes particles will the voids between large particles. There are four type of

grading which are Continuous grading, Poor grading, Gap Grading, and Well Grading.

There is no universal ideal grading curve satisfactory concrete can be made with various

grading of aggregate. However ISI has specified certain limit, within which a grading

curve must lie to produce a satisfactory concrete.

Silt Content- The value less than 150 micron is considered as silt.

j) Moisture Content of Soil sample:-

This test is done to determine the water content in soil by calcium carbide method as per

IS: 2720 (Part II) – 1973. It is a method for rapid determination of water content from the

gas pressure developed by the reaction of calcium carbide with the free water of the soil.

From the calibrated scale of the pressure gauge the percentage of water on total mass of

wet soil is obtained and the same is converted to water content on dry mass of soil.

Apparatus Required:-

i) Metallic pressure vessel, with a clamp for sealing the cup, along with a gauge

calibrated in percentage water content ii) Counterpoised balance, for weighing the sample

iii) Scoop, for measuring the absorbent (Calcium Carbide) iv) Steel balls – 3 steel balls of

about 12.5mm dia. and 1 steel ball of 25mm dia. v) One bottle of the absorbent (Calcium

Carbide)

PREPARATION OF SAMPLE

Sand – Coarse powders may be ground and pulverized. Cohesive and plastic soil – Soil is

tested with addition of steel ball in the pressure vessels. The test requires about 6g of

sample.



Fig.:-29 Moisture Content

Procedure to determine Water Content In Soil By Calcium Carbide Method

i) Set up the balance, place the sample in the pan till the mark on the balance arm

matches with the index mark. ii) Check that the cup and the body are clean. iii) Hold the

body horizontally and gently deposit the leveled, scoop-full of the absorbent (Calcium

Carbide) inside the chamber. iv) Transfer weighed soil from the pan to the cup. v) Hold

cup and chamber horizontally, bringing them together without disturbing the sample and

the absorbent. vi) Clamp the cup tightly into place. If the sample is bulky, reverse the

above placement, that is, put the sample in the chamber and the absorbent in the cup. vii)

In case of clayey soils, place all the 4 steel balls (3 smaller and 1 bigger) in the body

along with the absorbent. viii) Shake the unit up and down vigorously in this position for

about 15 seconds. ix) Hold the unit horizontally, rotating it for 10 seconds, so that the

balls roll around the inner circumference of the body. x) Rest for 20 seconds. xi) Repeat

the above cycle until the pressure gauge reading is constant and note the reading. Usually

it takes 4 to 8 minutes to achieve constant reading. This is the water content (m) obtained

on wet mass basis. xii) Finally, release the pressure slowly by opening the clamp screw

and taking the cup out, empty the contents and clean the instrument with a brush.

17.0 Information about Equipment



1) Mixer Plant: Mixer plant provides the facility to mix the various ingredients of

concrete in required proportions at the in order to fulfill the quantities of concrete and

without more lead distance. A concrete plant, also known as a batch plant, is a device that

combines various ingredients to form concrete. Some of these inputs include sand, water,

aggregate, fly ash and cement and the centre of the concrete batching plant is the mixer.

These employ computer aided control to assist in fast, accurate measurement of input

constituents or ingredients, as well as ties toghter the various parts and accessories for

coordinated and safe operation.

Fig.:-30 Mix Plant

2) Transit Mixer: It is used to transport the concrete from the place of production to the

site. Nominal capacity of Transit mixer is 6M3 and Total Geometric volume is 9M3. It is a

equipment which is used for transpoting the concrete from batching plant directly to the

place where it is to be poured. It has a wide range of application specially for mass

concreting works like high rise building construction and Dam and airports etc.The angle

of drum is 15° and drum speed varies from 0-14 rpm. It optimized the position of spiral

ensures maximum discharge of concrete. Weight of mixer is varies from 2500 kgs-

3760kgs. At our site there are 8 no of transit mixer which are used in different pocket.



Fig.:-31 Transit Mixers

3) Boom Placer: The use of static concrete pumps with stationary placing booms has

increased, especially for building construction. It is commonly referred to as a line

pump or trailer-mounted concrete pump. This pump requires steel or flexible concrete

placing hoses to be manually attached to the outlet of the machine. Those hoses are

linked together and lead to wherever the concrete needs to be placed. Line pumps

normally pump concrete at lower volumes than boom pumps and are used for smaller

volume concrete placing applications such as swimming, sidewalks, and single family

home concrete slabs and most ground slabs It is used to lift material from the bottom and

take it to the heights of building which would have been very difficult by labour. The

length of Boom Placer is 36m at our site.

4) Needle Vibrator: The Needle Vibrator, also known as immersion or poker vibrator

have a power unit and long flexible tube at the end of which a vibrating head is attached.

Wherever compaction is to be done, the vibrating head is inserted in the concrete.

Concrete vibrators consolidate freshly poured concrete so that trapped air and excess

water are released and the concrete settles firmly in place in the formwork. Improper

consolidation of concrete can cause product defects, compromise the concrete strength,

and produce surface blemishes such as bug holes and honeycombing. An internal

concrete vibrator is a steel cylinder about the size of the handle of a baseball bat, with a

hose or electrical cord attached to one end. The vibrator head is immersed in the wet

concrete.

Fig.:-33 Needle Vibrators

5) Tilted Drum Mixer: A concrete mixer (also commonly called a cement mixer) is a

device that homogeneously combines cement, aggregate such as sand or gravel, and

water to form concrete. For smaller volume works portable concrete mixers are often

used so that the concrete can be made at the construction site, giving the workers ample

time to use the concrete before it hardens. The entire drum rotates around its axis as

metals are loaded through a charge chute at one end of the drum and exit through a

discharge chute at the opposite end of the drum. Mixing blades are mounted on the inside

surface of the drum and as the drum rotates the blades mix by lifting and dropping the

materials during each rotation. Once the materials are sufficiently mixed the rotation of

the drum is reversed and the blade arrangement pushes the concrete through to the

discharge end of the mixer.

6) Bar Straighter Machine: This machine is used for cutting the bar as per requirement

in large quantities. The machine can do the operation of cutting up to 12mm dia. and for

bar having dia. greater than 12mm than Bar Cutter is used.

Fig.:-35 Bar Straighter Machine

7) Concrete Pump: Concrete is transported by pumping through steel pipeline from the

mixer to the place of deposit. It is also known as compressor. In this system, concrete is

conveyed from a central mixing plant to a place of pouring, by an arrangement of pumps

and pipelines. This pipeline is made of steel tubes each 3m in length and 100 to 125 mm

in diameter. Concrete can be pumped for maximum distance of about 400m in

horizontally and 80m in vertically. It is generally mounted below the concrete mixer so

that the mixed concrete can be fed straight into the hopper.



Fig.:-36 Pressure Pump

8) JCB Excavator: Excavators are heavy construction equipment consisting of a boom,

stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop

an undercarriage with tracks or wheels. A cable-operated excavator uses winches and

steel ropes to accomplish the movements. They are a natural progression from the steam

shovels and often called power shovels.

Fig.:-37 JCB Excavator Fig.:-38 Hydra (Cranes)

9) Hydra (Cranes): - These are used taking off heavy objects and also to transport them

from one to other place at the site. A crane is a lifting machine that principally works with

the use of pulleys and cables. For the construction industry, cranes are valuable assets

because they make working with heavy machinery and construction materials easy. The

invention of cranes made things easy for humankind because without them, loading,

unloading, and lifting had to be done by human hands, would consume more time, and

the entire system was not efficient at all.



Safety Measures on Operating Plants and Machineries

Before you operate a machine, ensure that the dangerous part of the machine has

been installed with a guard.

Avoid going to any area with insufficient lighting as there may be some dangerous

places which have not been provided with fencing.

Keep vigilant all the time and watch out for moving cranes, hooks or other lifting

equipment.

Before you use any electrical installation or tool, check the condition of its

electric cables.

Avoid dragging electric cables on the ground or allowing the cables to come into

contact with water.

Use electrical tools installed with an earth leakage circuit breaker.

Use and handle chemicals with care

l) 19.0 Safety Measure and Campaign

m) In Civil engineering construction project, accidents cannot be avoided. An event

can happen any time and unexpectedly during construction. About 80 percent of

accidents are mainly caused due to unsafe practices and shear negligence of the

workers. Safety measures are required to be built properly to motivate and

encourage the workers to work at the given site or industry without any fear,

tension or worry in mind about his security of life. Good safety measures are

essential to increase the output of work by generating safety free environmental

sense of contentment among the workers. Safety

measure can be efficiently handled by properly educating and training workers

about the safe rules and their importance. It is the foremost duty of construction

management to appoint separate safety engineer to undertake safety measure and

to prevent the occurrence of accidents. The causes of accidents should be properly

investigated and suitable measures should be adopted to control these accidents.

Thus, safety measures prevent:

1. Reduced workers’ compensation claims

2. Reduced expenses related to injuries and illnesses

3. Reduced absenteeism and Lower employee complaints

4. Loss of Life and Increased productivity

5. Improved employee morale and satisfaction

6. Reduction of hidden cost and Reduced insurance cost

Fig:-39 Safety Measures

o) Personal Safety

Wear protective equipment. Always wear safety helmet, safety vast and safety

footwear at construction site.

Do not drink or take drugs while working.

Pay attention to personal hygiene.

Do not play in the workplace.

Report to your supervisor immediately if you notice any unsafe condition

p) Public Safety

Pay attention to public safety. Members of the public are often unaware of or do

not understand the work carried out on construction sites and the hazards

involved.

Take great care to prevent the fall of materials from height.

Do not stack materials on floor edges or on scaffolds.

q) Safety Campaign:- An organized movement launched by an enterprise or

construction firm to advocate the safety rules and regulations among its workers

to reduce the number of accidents is termed as safety campaign. The following

points should be kept in mind for launching safety campaign.

1. The safety campaign must be placed under the charge of a very competent,

experienced and able manager, who may be termed as safety Director.

2. The worker should be frequently addressed in a small group in their language or

easy accessible language to explain about safety rules.

3. Do’s and Don’ts during construction work should be displayed in bold letter along

with diagram on chart paper

4. Advertisement films, Documentaries and CD should be shown to the workers on

off days, explaining about the need for safety measures.

5. Safety Slogans and safety Quotations should be made an integral part of safety

campaign to educate the illiterate and poor workers.

6. Training in first-aid should be provided to workers and supervisors for trating

minor cuts and injuries.

7. Safety journals should be brought about by the concerned management and

distributed free of cost to the workers.

r) 20.0 Intelligent Building

s) An intelligent building is one that provides a productive and cost effective

environment through optimization of its four basic elements- structure, systems,

services and management-and the interrelationships between them.

ad) The development cost of an Intelligent Building is 8 -10% higher than that of an

ordinary building. But this can be justified by the resulting energy saving, which

is only 25 ±35% of energy required by normal building.

ah) 21.0 Inspection and Quality Control

ai) Inspection is the process of carrying out vigilant checks during the construction of

project against any serious defect or lack of progress. Inspection of work is

carried from beginning of work up to the completion of project at various stages

or levels by competent authority. Quality control is the comparison of materials,

construction techniques and finishing products etc. with the laid down standards.

The quality control and inspection should ensure that the quality of work is the

accordance with the prescribed specification.

aj) Stages of construction:

a) Layout stage: It is the first stage of work to be inspected when the layout of

building is carried out. The layout should be properly checked for right angles and

dimensions must be measured as per plan.

b) Earthwork completion stage: At this stage, quality inspectors check the

adequate depth and width of excavation trench to ensure desired the depth of

foundation.

c) Foundation laying stage: At this stage, the quality engineer mainly inspects the

material reached at the site, such as quality of cement, sand, bricks and aggregate

to be used in foundations. The materials must be of the same quality as has been

inspected at the supplier’s premises. In general, a contractor always tries to use

over burnt or jhama bricks for the foundation for the foundation work which

should be objected.

d) D.P.C. laying stage: It is the one of the critical stage, which must be inspected by

the quality engineer. It is the completion of foundation stage, when damp proofing

course is laid at the top of foundation layer to protect the building from moisture.

At this stage, once again layout of building should be exactly checked as per the

building plan to ensure proper internal dimensions of rooms and its component.

e) Formwork erecting stage: Erecting formwork is one of the major stage of the

construction work, which must be given due attention by the quality inspectors.

The shape, strength and finishing surfaces of concrete in beams, column and slabs

mainly depend upon type of form work. For large project, only steel form work

should be used. For concrete construction forms or shuttering in the forms of

wooden planks or steel plates are used for keeping the green concrete in position

till it hardens. This helps in giving the desired shapes to different components of

the structure

ak)Removal of formwork

For columns = 24 to 48 hours

For slab up to 4.5 m span = 7 days

For slab more than 4.5m span = 14 days

For beams up to 6m span = 14 days

For beams above 6m span = 21 days

al) The good formwork should satisfy the following requirements:-

1. The material of the formwork should be practically water proof so that it can’t

absorb water from concrete.

2. It should be strong enough to withstand the pressure or the load of the fresh

concrete, live load of the worker coming on it.

3. The formwork should be so made that it can be removed easily without causing

the least injury to the surface of nearly constructed concrete members.

4. The inside surface of formwork should be smooth so as to give good appearance

to the resulting newly constructed concrete members.

f) Reinforcement laying stage: The strength of the structure member like beams,

column and slab depends upon the reinforcement provided. So, when the

reinforcement stage is laid over the formwork erected, it is right time for quality

engineers to inspect the work for identification of any defect with respect to

inadequate reinforcement detail.

ay) 23.0verall Benefits of Training

az) Internship is a class healed at site to provide an enhanced understanding of the

outside working environment before the student graduate. Student like civil and

urban engineering and other fields also take this practice. The main aim of this

practice (internship) is that to teach students communication with different

workers or employees, to improve practical skill what they learned at class, up

grading the theoretical knowledge in addition to the class, improve their

leadership skill, team playing skill and etc. I have acquired much knowledge in

different tasks as explained below in different section. That different knowledge

gets me a good performance in the internship period and I gain an experience that

helps me after the graduation in the upcoming working era of mine.

ba) Improving practical skill

bb) The aim of the internship is to address more practical knowledge for student. So, I

found a practical knowledge at the site as much possible within the four month.

The knowledge we have learn in the class is helpful to get those practical or real

work in the site and totally different from the actual knowledge gained from the

class. Thus I found some knowledge in the site which helps me to work with the

site environment or site peoples.

bc) Some of the practical knowledge I gain from the internship class was:

Construction of formwork and false work for some reinforced concrete structure.

In any construction work the first stage before casting of concrete is designing

and constructing of form work. As I explained in the work procedure the

formwork and false work must be stiff and must resist the fresh concrete till the

concrete gain its strength. Thus the construction stage of form work was new to

me since I‘m new for the practical world now I gain practical knowledge about

how it is worked and erected.

Bar bending, positioning, splicing and tying, according the specified drawing.

After the formwork and false work is ready the bar bending, positioning and tying

work goes next. This work is done based on the working drawing provided in the

working drawings (structural drawing) by the design team of that specified

structure. In most case it was new for me to see such work since it is a practical

work only performed at the site.

Surveying on building construction. We conduct the surveying class in the field

for its lab session of the course in the normal class. But we don‘t know about how

it is going to be in building construction in particular and in which particular stage

of the construction work it used either the super structure or sub structure.

Concrete is a vital material in any construction of reinforced concrete and is the

main constituent or ingredient of any reinforced concrete structure. Thus it is

mandatory to know this material in practice including how it is treated, placed

(poured), mixed and the equipment used for those work. I got the practical

knowledge in terms of those listed aspects of concrete.

Different construction equipment (machines) and their use in construction site.

Many of great structures before are a product of numerous human power and

countless days inspired by great powers. Machines are capable of handling tough

work which may be beyond the scope of human labor to be performed. They can

be expected to work with fair degree of effectiveness even under adverse weather,

climate or topographical conditions. I generally know how equipment‘s are used

in the site including their specific purpose.

bd) Upgrading the theoretical knowledge

be) The internship class is not only depending on the practical aspect but it also help

students to upgrade or increase knowledge on already that they have. I try to

integrate the practical knowledge with that of the theory learned in the class in

different place in order to get more knowledge than the theory we learned on the

class. I got the internship class very interesting in terms of upgrading a theoretical

knowledge and I learned from the site some theories that we haven‘t learn in the

class room by searching different related literature. Some of this is:

Quantity surveying

Structural design of shear wall and its advantage

Construction equipment

Report writing

bf) I learned those things in exclusive cause it is hard to read and understand

everything from books and asking some peoples at site to those things ashamed

me. Generally I change myself alit bit after the internship period in my knowledge

than before I took it.

bg)Upgrading interpersonal communication skill

bh) Communication is sharing or exchanging information or ideas with others in order

to get some messages and knowledge. The communications systems within the

building design and construction enterprise has taken on a large role in the

achievement of profitability and efficiency. A basic understanding of

communication systems is beneficial to all building professionals and trades, as

they all play a part in the success of the construction. Construction is one of the

places that ask a good communication skill either managing every trade of work

or asking what is gowning on over there. So, communication is an important way

of learning, which can be defined formally as the act, process, or experience of

gaining knowledge or skills and sharing what we know. Cool communication is

important in the real constructions world and it can appear in different forms as

speaking, writing, and listening. In the site the most things I gain is due to

communication with other workers like engineers, skilled and non-skilled

workers, Forman etc. in some place/case it is very difficult to talk workers and ask

them what we want because of that they underestimate us and sometimes they are

not eager to tell.

bi) Improving team playing skill

bj) Team playing skill for construction work Team works, especially for engineers,

involve in every piece of task and achieving good team playing skill is essential

for Effective completion of tasks and Increasing productivity. This skill already

exists in my personality in the campus due to different assignment and project

works that I work together with student. But this skill is more than this in the

construction site. In the construction site the work is already a team work and it

needs more closeness of workers to solve problems arise in different aspects,

misunderstanding in the drawing or working methodology and consult every

work. We the student at the site also works together as a team to get more

understanding and share ideas. More or less I improve my team work status by

working together with different professionals, student and workers as a whole in

the civil engineering works and consulting.

bk) Improving leadership skill

bl) Leadership is the process of influencing individuals or groups to accomplish an

organizational goal or mission. I have seen how each worker is controlled and

organized to perform its day to day activities. Among all other managements i

have seen that human resource management is the most important one. i have

actually observed the method of controlling the working time and amount of work

done by each worker so that the work proceeds according to the work plan

(schedule).Leadership is a skill to guide, control and monitor peoples. For

effective leadership i understood that personal values like confidence, effective

communication and devotion are very important.

bm) In order to be good Leadership the following criteria should be fulfilled.

bn) Those are:-

Be technically proficient (skilled with different knowledge‘s).

Seek responsibility and take responsibility for your actions.

Make sound and timely decisions.

Know your people and look out for their well-being.

Keep your workers informed.

Develop a sense of responsibility in your workers.

Ensure that tasks are understood, supervised, and accomplished.

Use the full capabilities of your organization.

Listening to others.

Being organized.

Able to communicate clearly and efficiently.

bo) In the site it was impossible to us to lead anything because we go to the site to

learn about the site work and we don‘t have enough ability to handle such works

in such short time but we have learned how to become a good leader and the main

signal of a good leader.

bp) Finally what I take hold of is Becoming a leader isn‘t easy because it takes a

conscious commitment and consistent effort to develop one‘s leadership skills

bq)Work ethics and related issues

br) The concept of work ethics may be summarized as the overall quality in one‘s

behavior towards appreciating the process of work flow and performing rather

well on the job so that this work flow will not be jeopardized in the long run.

During my internship program, I could say that I have managed to do my side of

the job description with a high spirit and enthusiasm so that there was a smooth

flow of activities both in the office and on construction site. Work ethics involve

such characteristics as honesty, responsibility, reliability, accountability and etc.

bs) Punctuality is one of the major issues that could be raised when talking about

work ethics and on my side I tried meet this criteria by attending to my working

station in time so that there will not be any delay on the activities planned for that

day. The behavior that one shows towards his peers and colleagues is also one

manifestation of the concept of work ethics. Personally, I always respected and

gave priority the employers of the company. Elements of work ethics that worth

mentioning are:-punctuality, honesty, reliability, office discipline, corporation and

responsibility.

bt) We us a student should follow the rules and regulations set by the company and

avoid complaining any work load, activity or assignment that may arise on the site

or office. It is a pleasure of supervisors if we have a good work ethics and we are

responsible for any given tasks. Since the aim of internship is to let students know

the outside environment pertinent to their field, which includes of such the above

dealt qualities, I was with the great interest that I tried to meet my responsibilities

and work ethics that I suppose to be fulfill by my side.

cm) The entire period of Industrial Training has given me good & important

practical exposure of construction work. At the end of the Industrial Training

under N.K.G. Construction Limited, Jalandhar Cantt, I feel myself better

equipped and ready to face the field problems related to Civil Engineering works.

In these four& half months, I have learnt how to deal with Authorities and

workers under supervision and I have become familiar with the fact that the field

work is much difficult from theoretical knowledge. But until you don’t have the

theoretical knowledge, the practical work is very difficult to carry-out and

understand.

cn) Working with experienced engineers has enhanced my technical skills to a

great extent for which I am grateful to them. Their professional approach towards work is

appreciable.

co) The training has provided me with much needed field exposure to shape

up my thinking in a better way as a professional making me a lot more capable to face the

challenges of life.
