PILE TEST SERVICES

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 test.

• Lateral pile load test.

Resources:

• A group of highly skilled workforce under permanent pay-roll.

• Large fleet of advanced equipments

Geotechnical Survey

Geotechnical 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.
