Deva - HVAC replacements

The National Park Service is soliciting proposals for comprehensive HVAC and evaporative cooler replacements across 22 facilities at Death Valley National Park in California. The project involves demolishing failed or failing HVAC systems and installing new equipment including central heat pumps, mini-split systems, air exchangers, and electric boilers, along with all necessary electrical and plumbing connections, testing, training, and documentation. Contractors must demonstrate technical competence, provide detailed scheduling approaches, and show relevant past performance experience, with these evaluation factors considered approximately equal in importance under a best value tradeoff methodology. The solicitation requires electronic submission of both technical and price proposals, and a mandatory pre-proposal site visit was scheduled for August 21, 2025. The original proposal submission deadline was September 15, 2025, with an amended performance period now running from September 27, 2025, to January 31, 2026.

This procurement is designated as a Total Small Business set-aside under NAICS code 238220 for Plumbing, Heating, and Air-Conditioning Contractors, with an estimated contract value between $250,000 and $500,000. The work involves replacing HVAC systems in 23 contract line items across various Death Valley National Park locations including Furnace Creek, Cow Creek, Stovepipe Wells, Emigrant, Grapevine, and Scotty's Castle, with equipment quantities ranging from 1 to 6 units per location depending on the facility size and requirements. The contractor will have 90 calendar days to complete the work once all HVAC units and materials are confirmed in-hand and ready for installation. Work hours are restricted to 06:00-16:30 for operational buildings and 07:00-17:00 for residential buildings, with strict adherence to National Park Service regulations and environmental protection requirements. The project must comply with Davis-Bacon Act wage determinations and maintain a minimum SEER2 rating of 15.2 for energy efficiency standards while preserving the historical integrity of park facilities.
