Our Geotechnical Division goal is to define and evaluate subsurface conditions and their potential impact on proposed or existing development. We can assist in all aspects of the project from site planning, to earthwork observation and testing, to final construction and beyond. Geotechnical services: • Geotechnical Feasibility Studies • Soil Improvement / Stabilization • Earthquake Engineering • Slope Stability Analysis • Soil Structure Dynamic Interaction • Seismic Refraction / Rock Rippability • Landslide Evaluations • Pavement Design • Geologic Hazard Reconnaissance • Seismic / Liquefaction Analysis • Fooundation Evaluations • Fault Investigations • Hydrogeologic Investigations • Geotechnical Instrumentation • Drainage / Seepage Studies • Field Permeability Testing
