A government authority in California is seeking a vendor to provide comprehensive geotechnical investigation and land surveying services for a lane bridge project. The scope of work includes subsurface exploration, laboratory testing of soil samples, engineering analysis, and providing foundation design recommendations.

Requirements cover the collection of representative soil samples for laboratory classification and testing, as well as recording groundwater conditions both during and after drilling—should groundwater be encountered. The vendor must provide recommendations for allowable bearing capacity for shallow foundations, propose suitable footing types and necessary embedment depths, and calculate active, passive, and at-rest lateral earth pressure coefficients. Additionally, the project involves a screening-level evaluation of liquefaction potential, with detailed analysis as needed based on site conditions.
