Deepak Parmar

2015 ICC Distinguished Service Award

Deepak ParmarDeepak Parmar has been an active member of the ICC for many years, contributing most extensively to Subcommittee C and working groups related to soil thermal characteristics.

Career Highlights


He holds a B.Sc. in Civil Engineering from Woolwich Polytechnic (1966, London, U.K.) and a Diploma in Management Studies from Slough Polytechnic (1972, U.K.).


During undergraduate studies, he worked at Soil Mechanics Ltd., London, U.K. in the geotechnical laboratory conducting specialized geotechnical and rock mechanics testing. After graduating he joined the firm in the capacity of laboratory manager, in charge of soil and rock mechanical laboratories and specialized field (in-situ) testing. From 1973 to 1978, he worked with two civil engineering consulting firms in Canada specializing in geotechnical and material testing, and instrumentation of tunnels and shafts in soft ground and in rock.

 In 1978, he founded Geotherm Inc., specializing in underground cable-related soil and backfill testing. He was retained on-contract by Ontario Hydro Research for two years to assist in winter earth-work studies as well on thermal aspects of soils and backfills for underground power cable applications. During this time, he worked on EPRI-funded projects for the design and development of the Thermal Property Analyzer and thermal aspects of soil and backfills.

Since 1980, Geotherm have undertaken numerous research contracts for Canadian government agencies as well as for electric utilities and cable manufacturers in Canada, other areas in North America, and overseas. These include:

• Building a database of Canadian soils through field and laboratory testing to correlate geotechnical and thermal parameters
• Evaluation of thermal parameters of soil, backfill and various types of concrete for earth energy storage/utilization (ground and ground water coupled heat pumps)
• Study of buffer materials for the storage and containment of low-level nuclear waste.

 Since founding Geotherm, Deepak has overseen the performance of more than 400 route thermal survey projects for underground and submarine cable crossings. He was a member of the team of experts retained to investigate the well-known cable failures that occurred in Auckland, New Zealand in the late 1990s.

Deepak Parmar received the 2015 Technical Committee Distinguished Service Award with the following citation: For his leadership in the area of thermal resistivity of soils and backfill materials, and testing the properties of those materials.
