Incorporated in 1964, Geotechnical Consultants, Inc. (GTC) provides consulting services in geotechnical engineering, engineering geology, and hydrogeology, primarily for public infrastructure projects in California.  We have applied our expertise in these disciplines to a wide range of projects such as the planning, design, and construction of dams, reservoirs, tunnels, pipelines, roads, bridges, light rail systems, airports, water and wastewater treatment facilities, pump stations, buildings, outfalls, and port facilities.  These projects have required research; geologic field mapping; aerial photo interpretation; subsurface exploration using drilling and trenching methods and cone penetrometer testing; land and marine geophysical surveys; in-situ and laboratory testing; geologic, engineering, and seismic risk analyses; construction observation and testing; and value engineering.
