Surveying and Geotechnical Investigation Services

The contract encompasses comprehensive topographic and subsurface surveying, geotechnical borings, and detailed soil analysis to support the design and construction of infrastructure in a low-lying, flood-prone region. These services are critical for understanding ground conditions, assessing flood risk, and ensuring structural stability in an area vulnerable to water inundation and soil instability. The scope includes collecting and interpreting data on elevation, soil composition, groundwater levels, and bearing capacity to inform engineering designs and mitigation strategies. Performed under a subcontract with Caltrans District 4, this work adheres to the NAICS code 541370 for geological and geophysical surveying services and is tied to a project in the Bay Area/Oakland region of California. The investigation will provide essential data to guide foundation design, drainage solutions, and erosion control measures, ultimately supporting resilient and safe construction outcomes. The contract was posted on July 1, 2026, and all activities are focused on enabling long-term infrastructure integrity in a challenging environmental context.
