About this opportunity
The Department of the Navy Naval Supply Systems Command is seeking a contractor to perform comprehensive maintenance, repair, and preservation work on two Naval vessels, TWR-7 and TWR-8, located at Puget Sound Naval Shipyard in Bremerton, Washington. The solicitation (N4523A25R1052) requires a qualified contractor to conduct pierside modernization work at their own facility, including extensive hull repairs, system overhauls, tank inspections, mechanical replacements, and sea trials for two 85-foot aluminum vessels. Key contract requirements include facility location within the Puget Sound region (between Olympia and Bellingham, WA), capability to dock and service 95-ton displacement vessels, and adherence to commercial marine industry standards. The government will evaluate proposals using a lowest price technically acceptable methodology, with technical factors including corporate experience, past performance, and facility capabilities. Critical dates include a proposal due date of March 21, 2025, with an anticipated contract award in April 2025 and a performance period from June 3 to November 21, 2025.
The contract is a 100% small business set-aside under North American Industry Classification System (NAICS) code 336611, with a size standard of 1,300 employees. Each vessel (TWR-7 and TWR-8) represents a significant maintenance project with an estimated unit value of $20,000,000, though the contract value is not explicitly stated in the solicitation. The work scope is comprehensive and includes specialized tasks such as sweep blasting hull surfaces, replacing fendering, inspecting and cleaning tanks and voids, overhauling bow thrusters and steering systems, replacing air compressors and HVAC components, and conducting detailed sea trials. Both vessels are 16-year-old aluminum hull vessels with identical dimensions: 85 feet long, 21.5 feet wide, with a 5-foot 8-inch draft and 95-ton full displacement. Contractors must provide a secure office space for government representatives and submit numerous technical reports and documentation throughout the project, with work to be performed entirely at the contractor's facility in the specified Puget Sound region.
