Z--C&O CANAL NATIONAL HISTORICAL PARK - FY26 REPAIR I

Solicitation 140P3026R0002 is a request for proposals for construction services to repair Inlet Lock 2 at the Chesapeake and Ohio Canal National Historical Park in Potomac, Maryland. The scope of work includes replacing deteriorated lock gates and miter sills, repairing stone masonry, removing sediment and debris, and repairing berms upstream of Violette's Lock. This is a 100% total small business set-aside under NAICS code 237990, with an estimated magnitude between $500,000 and $1,000,000. The resulting contract will be a firm-fixed price award with a performance period from September 30, 2026, to August 31, 2027, requiring completion within 335 calendar days of the notice to proceed. The government will utilize a best value tradeoff process for the award, where technical capability and past performance are weighted more heavily than price. Proposals must be submitted electronically by September 18, 2026, and must include a signed SF-1442, a bid bond for 20% of the proposed price or $3 million, and a limitation on subcontracting report. Key requirements include adherence to the Secretary of the Interior Standards for Treatment of Historic Properties, OSHA safety guidelines, and Davis-Bacon Act prevailing wage rates. The project includes a base requirement for the lock repair and several optional CLINs for dry stack wall repairs, additional repointing, and bridge work.
