Bathymetric Surveying and Pre/Post-Dredge Mapping

This contract requires the execution of high-precision bathymetric surveys to measure seafloor or waterbody depths before and after dredging operations, with the primary objective of validating the exact volume of sediment removed. Accuracy is critical, as the post-dredge depth must not exceed a tolerance of 3 feet beyond the target depth, ensuring compliance with environmental and engineering specifications. The work is conducted as a subcontract under NAICS code 541370, which classifies it as a professional, scientific, and technical service related to surveying and mapping. The activity is associated with the Fish and Wildlife, Region 2 - Northern Central office located in Rancho Cordova, California, indicating the project likely supports habitat restoration, navigation channel maintenance, or ecological preservation efforts under state oversight. All survey data must be rigorously documented and analyzed to substantiate operational outcomes and regulatory adherence.
