We provide geotechnical consulting services to facilitate project development. Our experience includes new homes, residence additions, infill to medium size subdivisions, commercial buildings, wineries, parking structures, roadways, bridges, retaining walls and tennis courts.

We also provide geotechnical services to insurance companies, homeowner associations, real estate and legal firms.

In the geologically active Bay Area we provide landslide evaluation and mitigation, as well as provide seismic design criteria to meet current building code requirements.

For building projects we assist with project siting, geologic hazards evaluation, subsurface geotechnical investigations and construction observation.

We evaluate soil, geologic, seismic and groundwater conditions to prepare design criteria and recommendations aimed toward project development, design and construction of foundations and drainage improvements.

The geotechnical criteria provided will aid your architect and engineers to design, and your contractor to build your project in conformance with current building code and construction practices.
