Z--Lowell National Historical Park; Rehabilitate Bath

The National Park Service, Northeast Region, is soliciting proposals for the renovation and modernization of restroom facilities at the Morgan Cultural Center within Lowell National Historical Park in Lowell, Massachusetts, under solicitation number 140P4326R0014. This firm-fixed price contract is set aside entirely for small businesses under FAR 19.5 and falls under NAICS code 236220 for commercial building construction, with an estimated value between $500,000 and $1,000,000. The work includes selective demolition and new construction of electrical, plumbing, mechanical, and fire protection systems across approximately 560 square feet of space, covering restrooms on the second and third floors of the building, all to comply with the Architectural Barriers Act Accessibility Standards and applicable building, plumbing, mechanical, and electrical codes. Brand-specific products are mandated, including Bradley sink units, DURAFLEX materials, and Koala Kare baby changing stations, and all materials must be delivered in original manufacturer packaging with proper labeling and documentation. The project must meet strict accessibility requirements under the ADA and ABA, and adhere to the Buy American Act for construction materials. Proposals must be submitted electronically via email by the deadline of June 11, 2026, to Mari Tolleson, the Contracting Officer, and organized into two volumes: a technical proposal and a business and price proposal, with each attachment under 30 MB. Offerors are required to demonstrate past performance on comparable restroom renovation projects within the last five years, as failure to do so results in automatic technical unacceptability. Evaluation will follow the Best Value Continuum Tradeoff Process, with non-price factors—such as technical approach, management plan, and past performance—collectively weighted equally with price. The contractor must comply with Davis-Bacon wage determinations, submit required bonding and insurance documentation—including 100 percent performance and payment bonds—and complete the Limitation on Subcontracting Report. The performance period runs from November 16, 2026, to May 14, 2027, with payment processed electronically through the Treasury’s Invoice Processing Platform upon submission of detailed documentation including payment estimates, current schedules, and the CMR Checklist. Contractors must also maintain inspection records, notify the Contracting Officer ahead of key phases, and provide a release of claims using Form DI-137 prior to final payment.
