Surveying and Geotechnical Engineering

The contract entails topographic and boundary surveying along with subsurface soil testing and geotechnical analysis for a development project situated on former rail corridors and areas adjacent to wetlands. This work is critical to establishing accurate land contours, property lines, and subsurface conditions necessary for safe and compliant construction in environmentally sensitive and historically altered terrain. The scope ensures that engineering designs account for potential soil instability, groundwater interaction, and regulatory constraints tied to wetland proximity and former industrial use. The project is administered by the City of Pittsburg, California, with a NAICS code of 541370 indicating it falls under engineering services. The contract is classified as a subcontract with a posted date of July 30, 2026, and performance is required within the city of Pittsburg, zip code 94565. The geotechnical data collected will inform foundation design, drainage systems, and mitigation measures to comply with environmental and structural standards, ensuring the development proceeds with reduced risk of land movement, erosion, or ecological disruption. All surveying and testing must adhere to local regulations and industry best practices for sites with complex geohydrological conditions.
