7. 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

8. 6 IES
Setting Up: 1991- 1997
IES 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 DynamicTesting 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: 2007-2012
In 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

mechanical rotary boring machine for bored pile
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 onward
Since 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.

BoredPile 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.

DrivenConcretePile
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.

HighStrainDynamicTestingofPile
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
www.pdaproficiencytest.com to see proficiency
level. Since the beginning we did PDA for projects

PileIntegrityTestingWork 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.
Thisprocedureisperformedwithahandheldhammer
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
Thismethodisstandardizedby ASTMwithdesignation
D5882 “Standard Test Method for Low Strain Integrity
Testing of Piles”.

GeotechnicalInvestigationWork
Geotechnical investigation is an engineering practice
toevaluatesoilandrockparametersthosearerequired
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.
