J--COLONIAL NATIONAL HISTORICAL PARK - REPLACE HVAC

The contract entails the replacement of HVAC systems at the Jamestown Historic Research Center within Colonial National Historical Park in Williamsburg, Virginia, under a total small business set-aside for NAICS code 238220. The project requires the installation of two 5-ton air handlers—one Liebert and one Carrier—and two Goodman heat pumps, all from a single manufacturer and fully compatible with the existing controls system. Work must begin within 14 calendar days of receiving the notice to proceed and be completed within 168 calendar days, with a performance period spanning from July 1 to December 30, 2026. The solicitation mandates strict adherence to Davis-Bacon wage rates under VA20260157, and contractors must provide performance and payment bonds equal to 100 percent of the contract value within 10 days of award, with coverage extending for the full performance period plus one additional year. All work is subject to government inspection at all times, and the contractor retains full responsibility for quality control, material integrity, and site hazard assessment, regardless of government oversight. Proposals must be submitted electronically in two volumes via email to the contracting officer, adhering to specific formatting and file size requirements, with no hard copies accepted. Technical proposals must address equipment selection, ductwork modifications, and control system integration, while management proposals must detail the project manager’s qualifications, technician certifications, staffing plan, subcontractor use, and mobilization capability. Past performance, price, and compliance with federal representations and certifications—including SAM registration, labor standards, and prohibitions on certain international business activities—are evaluated under a lowest price technically acceptable (LPTA) process, where all non-price factors are of equal importance and collectively weigh approximately the same as price. Final acceptance requires correction of all deficiencies, submission of a cut-sheet binder with equipment documentation, warranty information, and operation manuals, and completion of a final walkthrough with National Park Service staff. Payment must be processed through the Treasury's IPP system, with a draft invoice submitted five business days in advance and the final payment contingent upon satisfaction of all contractual obligations, including the submission of a release of claims using Form DI-137.
