Bridge 01, Hatirjheel Intregrated Development Project1200φ Depth-32m, Nos-86 bored RC pile constructed by IES

5 IES

Long back, in mid fifties of the last century, geotechnical

engineering services i.e. soil investigation and bored pile

construction has been introduced in the then East Pakistan

under the entrepreneurship of Swiss Boring, later, the

company switched over to Soiltech International Ltd in

the year of 1971, just after independence of the country.

Other than Soiltech International Ltd, few other company

grew under the leadership of local engineer, and started

practicing geotechnical engineering in real life project. But

work volume failed to attract others to this profession.

Over time, economy of the country gained momentum and

development work volume amplified but this specialized

geotechnical engineering did not move forward, rather, we

want to say, quality and services declined. Non-professionals

dominated the industry and in most cases people took it

simply as business. Now it's time to set a new benchmark

and set on our missions are to:

• Incorporate updated technology.

• Procure modern equipment and instrument.

• Improve skills of local engineers and entrepreneur.

• Develop human resources.

Philosophy & Mission

6 IES

Setting Up: 1991- 1997IES launched late in 1991 by Engr. Abu Mohammed Masud, without any financial investment and without any employee on payroll. Onset a very small geotechnical laboratory setup in a rented garage. In early 1992, Beximco Engineering Ltd awarded a small contract of bored pile work for Rangunia – Hathazaree electrical transmission line at Chittagong. That was the beginning and later in following years IES did many small diameter bored pile construction project and completed successfully. Few of them are can mentioned here- UGC building, laundry building of Hotel Sonergaon, Parishankhyan Bhaban at Agargaon, Twin tower, Concord Grand at Shantinagar, Concord Regency at Panthapath, Golf Heights at Banani, ShundarbanTechnopark at Darussalam etc and many other small building projects.

Decade for Stabilization: 1998- 2007 Onset IES faced a lot of troubles due to faulty workmanship of out sourced mechanical work that resulted in huge backlog and idle time. To overcome the crisis, IES set-up one mechanical workshop and started repair and maintenance of their own equipment and machines and IES got new momentum in site works.

During this period we have constructed bored pile by conventional method for many prestigious projects having national importance. Off them we may mentioned bored pile for Hatubhanga bridge

on Bangshi river at Mirzapore, Crown Cement Ltd at Mukterpur, Dhaka-Sylhet highway under Ircon International Ltd, Hz Shah Paran Bridge on Sylhet bi-pass road, Lafarge Surma Cement plant at Chattak under Lerson &Toubru Ltd, Kin Bridge Sylhet etc and many other projects.

During this period IES also started non-destructive pile testing work – PIT, Pile integrity test and PDA, High Strain Dynamic Testing for quality assurance test of pile foundation. Also, procured equipment for high tonnage pile load test work and conducted many pile load test having test load more than 500 ton.

Stage of Development: 2007-2012In 2007, we had under taken a large diameter bored pile work for Arch bridge on Gulshan Lake between Banani and Gulshan. Technical specification restricted the rotary boring method to follow. IES have rented one table drive rotary drilling rig for the work but failed to accomplish drilling. As a result, engineers and workers had been humiliated and insulted by the client and consultant. IES took that as challenge and started brain storming to develop a machine to accomplish the job. Finally, collected old components from Dholaykhal and assembled in their own workshop to make a drilling machine and finally succeeded and finished the piling work by newly developed rotary boring machine. This is a mile stone development of IES which boosted engineers and workers to go ahead. Presently, IES have big fleet of

construction and successfully used in many prestigious projects of the country like- Hatirjheel integrated development project, Mirpur-airport road flyover, box girder bridge on river Brhammaputra at Gaffargaon, Y-bridge on river Titas at Bancharampur, bridges on Mahananda at Chapai, Gangachara bridge on river Teesta in Rangpur etc.

Another new division started on by procuring new diesel hammers and pile drivers to undertake many projects. Such as the 22,000 Flat construction project of RAJUK. IES procured new diesel hammers from Delmag, and now, have a fleet of diesel hammers ranging from D22 to D46 with pile drivers and are on the top of the list of contractors having highest number and heaviest diesel hammers and pile drivers.

During this time IES have widened and introduced High Strain Dynamic Pile Test by procuring two sets of Pile Driving Analyzers and Pile Integrity Testers from Pile Dynamics Inc, USA and engineers and technicians obtained certification from overseas training and proficiency test from PDCA & PDI.

IES, procured 2500 ton and 1500 ton test setups and expanded their ability to conduct static pile load test up to 2500 ton. IES also procured half dozen vibrating wire load cells, displacement transducers, 16 channel data loger, readout unit fot instrumentation of static pile load test. This is anew horizon and IES become only service provider for instrumented pile load test.

Advancement with New Technology: 2013 onwardSince inception IES always looked forward with a vision to utilize modern machineries and practices essential for geotechnical engineering; and develop human resources on par with the international geotechnical sector. All their focuses are being collectively directed to become a leader of this nation’s geotechnical service providers. This has already been achieved and become the only piling and testing contractor in the country, who have introduced: Hydraulic drilling rig for bored cast-in-situ pile; fleet of new diesel hammers; CFA piling; performing static axial load tests using the most sophisticated and precise instruments—displacement transducers and load cell; and introducing dynamic testing of piles.

IES have also taken initiatives to modernize the nation’s geotechnical investigation sector. At present, IES is the only geotechnical firm to implement the usage of auto-trip hammer to carryout standard penetration test (SPT) and developed double tube thin walled vacuum sampler for collection of undisturbed soil samples. In addition, the entire operation is digitally recorded and submitted to our clients. In the process, the quality assurance is also guaranteed. Furthermore, it is also in our intention to introduce internationally accepted CPT; and seismic survey to clearly map out geotechnical features of a particular location.

Pile Bored cast-in-situ RC pile technology is the most popular

deep foundation construction method, which introduced

in the country, by few foreign companies, since mid fifties

of last century. Unfortunately, no significant advancement

have been accomplished to improve quality, rather than

acquire few hydraulic powered rotary boring rig by general

contractors in last three to four years. Introduction of such

sophisticated hydraulic rigs is definitely a forward step but

machines by themselves do not ensure good quality.

We are Emphasising on the construction technique that

may ensure quality of bored pile as well as the economy.

We feel that quality of bored pile can be ensured by adding

a few activities in methodology such as skills of worker,

overall management and few techniques. Based on our

past experience and knowledge, we have developed and

established following activities, which can improve quality of

bored pile substantially.

Essence of our services:

• Develop proper methodology.

• Use proper equipment.

• Central quality control management.

• Proper borehole flashing technique.

• Proper concrete pouring technique.

Pile

Timber trunks were used as foundation piles in ancient times

but, with time, steel and concrete took over as the preferred

materials. Driven pile technology was first introduced in

Bangladesh for the first sea port in Chittagong. Large steam

and pneumatic hammers were used in that project. But after

independence of Bangladesh in 1971, the technology not

moved forward.

Currently, Public Works Department and other government

and private organizations emphasis the use of concrete

pre-cast driven piles for building foundations. Considering

the market demand, IES procured numbers of new and

refurbished open end diesel hammers and pile drivers. At

the moment, IES has a fleet of diesel hammer based pile

drivers and skilled workers.

IES, also equipped with sophisticated software GRL WEAP

for drivability analysis and automatic hammer blow counter

ESAXIMETER of Pile Dynamics Inc, USA. Drivability analysis

and hammer performance test enable piling contractor to

select most appropriate hammer for driving piles.

Pile

Load

Test To evaluate movement and deformation of pile

shaft under load are the main objectives of pile load

test. During early stages, IES started pile load test

work, their 1st job was to conduct pile load test in

compression on a pre-cast concrete pile for a bridge

at Talma, PS- Boda, District- Panchagar under Local

Government Engineering Department. Journey

started at Talma with a 60t static axial pile load test,

presently capable and equipped to conduct very high

tonnage load test, up to 2500 ton test. We are now on

the top of the list of pile load testing contractor of the

country.

Apart from these, IES is now fully equipped with all

the latest technology and devices used in industrially

and technologically advanced countries. Very recently,

IES has introduced instrumented pile load test. Few of

them are mentioned below:

• Measuring applied load by load cell, up to 2000

ton,

• Pile movement measured by displacement

transducer.

• Use of hemi-spherical seat to minimize eccentric

load.

• Data logger and electric readout unit for electronic

data acquisition.

• Measuring deformation of concrete pile shaft

by using onetime concrete embedment strain

gauges at different level of pile shaft.

Presently, following pile load test services available

with us:

• High tonnage static axial compression pile load

test by kentledge method using concrete block.

• High tonnage static axial compression pile load

test by anchor method.

• High tonnage static axial uplift/ tensile pile load

Pile Estimation of pile capacity by using driving formula

were introduced in early 1940s by very prominent

engineer including Karl Terzhaghi. About a decade

later EA Smith of Raymond Pile Driving Company

developed a numerical method to estimate pile

capacity using wave propagation. Dynamic formulas

have largely been replaced by more accurate wave

equation analysis and high strain dynamic testing,

although formulas are still occasionally used in spite

of their inaccuracies and the fact that they cannot

predict stresses during driving.

Now a day, the PILE DRIVING ANALYZER system

(PDA) is the most widely employed system for

Dynamic Load Testing and pile driving monitoring

worldwide to asses the capacity of piles, PDA also

evaluates resistance profile, skin and toe resistance.

shaft integrity and investigates driving stresses and

hammer performance during pile installation.

IES procured two PDA hardware set (PAX-8 & PAX-4)

and software and have been practicing since last

few years. Few of IES engineers also took overseas

training to obtain proficiency certificate, please visit

k A pile integrity test is a method of testing deep

foundation to asses the defects, faults, change in

diameter of the pile shaft. The method also known as

low strain dynamic test, sonic echo test, and low strain

integrity test.

The technique is developed based on wave

propagation theory. A light impact is applied to a pile

top that produce a low strain. The impact produces

a compression wave that travels down the pile at a

constant wave speed and reflects when encounter a

change in cross sectional area or void/crack in material

or weak concrete.

This procedure is performed with a hand held hammer

to generate an impact, an accelerometer or geophone

placed on top of the pile to be tested to measure

the response to the hammer impact, and a data

acquisition and interpretation electronic instrument.

The test works well in concrete or timber foundations

that are not excessively slender. Usually the method is

applied to recently constructed piles that are not yet

connected to a structure

This method is standardized by ASTM with designation

D5882 “Standard Test Method for Low Strain Integrity

Testing of Piles”.

Wor

kGeotechnical investigation is an engineering practice

to evaluate soil and rock parameters those are required

for design a appropriate foundation of engineering

structure. Comprehensive, precise, detail and reliable

investigation can reduce construction cost, time

and human safety substantially. On the other hand

improper geotechnical investigation always deceives

or betrays engineers and entrepreneurs. Most of the

foundation designs are being done in Bangladesh

on the basis of SPT N-value. Many design engineers

need only SPT N-value. Due to versatility of SPT, many

correlations are available, which enables engineers

to estimate soil parameters like shear strength, unit

weight, relative density, volume compressibility etc. It

is very important to determine SPT N-value correctly,

precisely without forgery and fraudulent. Improper

instruments, instrumental error, human error,

deliberate intentions, fabrication of data in the field

by manipulation are the major cause of unreliable

SPT N-values. Upon pin pointing the causes, IES

introduced following activities in geotechnical

investigation, which can reduce un-reliabilities:

• Auto trip gear for releasing hammer- ensures

requsit energy and precludes human error.

• Proper instrument- precludes instrumental error.

• Capturization video footage of SPT activity by

digital camera- precludes data fabrication in field.

• SPT N-values re-counted from captured movie.

• Reliable lab test.
