Geotechnical Engineering in {{lpg_city}} {{lpg_state}}

DESI takes pride in offering professional Geotechnical Engineering in {{lpg_city}} {{lpg_state}} for major clients in the NY Metro area and North-East Region of the country. Under the guidance of founder and president of the company Ram Tirumala, P.E., who himself is a geotechnical engineer with MS in Geotechnical Engineering from NJIT, DESI has successfully completed many innovative geotechnical projects.

As per a quote from Carl Terzaghi, known as the father of Geotechnical Engineering in {{lpg_city}} {{lpg_state}}, “As soon as we pass from steel and concrete to earth, the omnipotence of theory ceases to exist”.

Steel and concrete are manmade materials and we can control the properties. In contrast, there would be many unknown factors when dealing with sub-surface soils. Keeping this in mind, engineers at DESI strive to ensure that apart from theory, all pertinent project information is reviewed and evaluated during the investigation process to enable development of ideal foundation solution. Geotechnical investigation my cost a few thousand dollars; however, overly conservative designs and costly repairs cost hundreds of thousands of dollars. Geotechnical Investigation is often overlooked during the planning phase due to lack of time and / or budget.

To ensure success of the projects, DESI recommends required investigation during initial consultations with the clients. Due to the ever increasing constraints for any development project in urban environments, owners and clients are pressed for innovative design methods. The constraints include space restrictions for construction equipment, strict regulations of local agencies, unsuitable sub-surface conditions consisting of fill / debris, obstructions due to underground utilities, ducts and tunnels. Construction of major foundation in such urban environment is a challenge and requires modification of traditional design methods. DESI develops project specific design solutions tailored to the means and methods of our clients by interacting with them on a constant basis.

Geotechnical engineers constantly deal with varying sub-surface soil conditions and development of ideal design parameters is beyond basic review of soil boring records and SPT values. Engineers have to derive optimum design parameters keeping all aspects of the project in consideration.
