PDC’s geotechnical engineering services included subsurface exploration, site characterization, laboratory testing, developing site preparation and foundation recommendations for planned improvements, and reporting results of our studies. Our services also included assessing cut slope stability and providing mitigation measures to reduce the risk of cut slope instability.

Field exploration consisted of ten test pit excavations. Laboratory testing consisted of grain size distribution and moisture content analyses along with soil classifications based on testing results.

Our geotechnical study recommendations report included detailed recommendations for: site preparation and engineered fills; allowable bearing capacity for conventional shallow foundations; lateral earth pressures; construction dewatering; driveway and parking area pavements; and cut slope stability. Our recommendations considered site development challenges such as steep terrain, loose, soft, and/or compressible soils, surface and groundwater control during construction, and frost-susceptible subgrade soils.
