Surveying and Hydrographic Mapping

The contract requires the execution of comprehensive hydrographic surveys before, during, and after dredging operations to confirm that the targeted depth of minus fifty feet mean lower low water is achieved and to accurately measure the volume of material removed. These surveys are critical to verifying compliance with established dredging specifications and ensuring that the project meets regulatory and operational standards. The work involves precise data collection and analysis using hydrographic mapping techniques to track changes in seabed elevation throughout the dredging process. This subcontract is issued under NAICS code 541370 and is managed by the Department of Defense under the W075 Endist San Fran office. The solicitation was posted on April 28, 2026, with a firm deadline for responses on May 28, 2026, at 7:00 PM. The place of performance is not specified in the provided data, but the work is expected to occur at a location where dredging activities are scheduled to meet the mandated depth requirement. All surveying activities must be conducted to support accurate reporting and accountability for the dredging effort under the terms of this agreement.
