One of our principal activities, which usually requires the combined expertise of our geologists and geotechnical engineers, is the investigation of subsurface conditions for construction of all types of engineering structures.  Working with other design professionals, we perform the appropriate subsurface explorations and analyses.  We provide recommendations and design criteria for foundations and other elements of the project, which depend on subsurface conditions.

GSI provides the required expertise for planning, design, and development of mitigation measures to be implemented during construction, maintenance operations, and major areas of considerations, including the following:
