Written by GovTribe AI · Jun 10, 2025

These are engineering design plans for the Military Ocean Terminal Concord (MOTCO) Berms Construction and Dredging Project, prepared by the U.S. Army Corps of Engineers San Francisco District. The comprehensive set of technical drawings details multiple critical project components, including dredging limits for Wharves 2 and 3 to a depth of -35 feet (MLLW), construction of two detention basin cells with specific fill elevations and berm configurations, and a designated borrow area. The project involves complex site preparation, including Munitions and Explosives of Concern (MEC) screening, material transportation, liner installation, and effluent water discharge, with precise engineering specifications for earthwork, slopes, and material placement across various project locations within the MOTCO facility in Contra Costa County, California.

The project documents include detailed site plans, cross-sections, and geospatial coordinates for each project element, with specific technical requirements such as 1:2 horizontal to vertical slope ratios, compaction specifications (92% laboratory maximum dry density), and precise elevation markers for fill and berm construction. The design incorporates existing infrastructure considerations, including railroad tracks, highways, and security checkpoints, with specific provisions for UXO technician support, environmental controls, and staged construction methodologies. The solicitation (W912P725BA013) indicates an estimated project cost between $10-25 million, with full and open competition procurement approach under NAICS code 237990.
