ABSTRACT for Mud Mountain Dam Steel Liner Repair

The Mud Mountain Dam Steel Liner Repair project issued by the U.S. Army Corps of Engineers, Seattle District, is a small business set-aside solicitation under NAICS code 237990, with a response deadline of November 19, 2025. The project entails repairing the steel liner within the 9-foot tunnel inlet at Mud Mountain Dam, requiring comprehensive site preparation, dewatering, sediment removal, installation of new steel plates, epoxy patching, and grout injection, all performed within a strict outage window from July 20, 2026, to September 30, 2026. The work must adhere to USACE safety standards, specifically EM 385-1-1, and involve confined space safety protocols, lighting, and ventilation systems. The contractor is responsible for all materials, labor, supervision, and emergency demobilization planning, with the goal of restoring the tunnel's integrity while preventing fish injury and hydraulic issues. The solicitation emphasizes compliance with all applicable federal, state, and local codes and standards but does not specify particular FAR or DFARS clauses within the available documentation. It also does not detail specific contract clauses, evaluation criteria, or award procedures; these are likely included in the full solicitation package. The project’s scope includes site-specific tasks such as sediment disposal at designated onsite locations, maintaining existing drain holes, and ensuring welds and surfaces meet technical standards. While the bid abstract indicates multiple offers with a government estimate of approximately $1.7 million, no explicit pricing schedules or line-item details are provided in the current documents. Proposal submission instructions are minimal, referencing the PIEE portal for document access, but lacking explicit format or volume requirements, with the primary point of contact being Charles Idle. Overall, the contract centers on a technically demanding, time-sensitive repair operation with strict safety and environmental considerations, governed by general federal and USACE standards.
