Gilpin Geosciences, Inc. (GGI) provides earthquake, engineering geologic and environmental consulting services to public and private sector clients throughout northern California. We are a small specialized firm of five professionals and office support staff that can focus on the acute needs of our clients regarding site development, hazards and planning issues. We work with a number of engineering firms with which we share geotechnical and geological support services.

We conduct all levels of geologic hazard investigations, from preliminary site studies to slope reconstructions. Among the services we perform are:

• Geologic hazard analysis for project feasibility and preliminary planning stages. 
• Geologic investigations for design level planning stages. 
• Geologic and geotechnical input for Environmental Impact Reports and planning projects for both public and private sector clients.
• Geologic investigations for recent geologic failures, such as landslides, sink holes and streambank erosion.
• Hydrogeologic investigations to characterize soil and groundwater conditions for purposes of site remediation and development.

For your preliminary project planning and construction purposes we are capable of rapidly reconnoitering and characterizing your project site because of our broad field mapping and aerial photographic analysis experience in the San Francisco Bay area. Detailed aerial photographic research and analysis, combined with field mapping and subsurface exploration, is used to identify active faulting and slope stability hazards.
