Terence Holman, Ph.D., P.E.

Terry Holman is a Senior Principal Engineer with more than 25 years of professional experience focused on the areas of: geotechnical and geostructural engineering; design; construction management; specialty geotechnical construction; heavy-civil construction; and environmental heavy demolition. Terry leads Geosyntec's Geostructural and Construction Engineering initiative.


Developed through his career as a geotechnical engineer, specialty contractor, and construction manager, Terry's technical expertise bridges the fields of design and construction, encompassing: shallow and deep foundations for stadiums, airports, large public assembly structures, large bridge projects, commercial, industrial, institutional, and power plant structures; deep excavations in soft ground; construction dewatering; ground improvement; high seismic hazard areas; working platforms for heavy crane lifts and large equipment; temporary structures; heavy environmental demolition; CQA-CQC; and construction claims and litigation. Examples of key projects where many of these skill sets were employed are the new Los Angeles Sports and Entertainment District in Inglewood, California;  Jacob Javits Convention Center Expansion in New York City;  Manchester Pacific Gateway in San Diego, California; California DGS New Natural Resources Headquarters Building in Sacramento, California; LAX Midfield Satellite Concourse in Los Angeles, California; Maine Medical Center in Portland, Maine; Audi Field in Washington, D.C.; and Humboldt Bay Nuclear Power Plant Decommissioning in Eureka, California.

Terry's practice and client service in geostructural engineering and construction is centered around the philosophy of identifying the most appropriate construction technologies and equipment based on ground and project conditions, and includes developing robust, aggressive designs for major geotechnical structures that are compatible with these constraints and acceptable risk profiles. He is the author or co-author of 21 peer-reviewed technical papers on geostructural and construction-related topics. Terry leads the industry by serving as an elected member of The Moles, a member of the International Association of Foundation Drilling (ADSC), and active membership in the Deep Foundations Institute (DFI), ASCE, and the Geo-Institute. He currently serves as the Co-Chair of the joint ADSC-DFI Working Platforms Group group tasked with developing technical guidance, contract language, and guiding regulation development for heavy foundation equipment safety. He has also served as Chair of the joint ADSC-DFI Micropile Committee, Chair of the DFI Tiebacks and Soil Nailing Committee, and Chair of the ASCE Metropolitan Section Geotechnical Group in New York, New York. Dr. Holman was named as the 2018 Pennoni Alumni Engineering Lecturer by Drexel University's Department of Civil, Architectural, and Environmental Engineering.
