Z--HVAC Upgrades, Mammoth Cave National Park

The National Park Service at Mammoth Cave National Park in Kentucky is seeking to upgrade its aging HVAC systems through a contract to replace eighteen units across eleven park buildings. This project aims to install modern, energy-efficient HVAC systems that will enhance reliability, indoor air quality, and temperature control, addressing various facility types including administrative offices, housing, training centers, law enforcement, and operational support buildings. The work will include removal of the existing equipment, installation of new split and packaged systems, integration with current electrical and ductwork, and comprehensive system testing and commissioning. The project is slated to run from early August 2026 through August 2027, with an estimated cost range of $200,000 to $500,000. This procurement is a total small business set-aside and currently in the pre-solicitation phase, inviting interested firms to submit their qualifications by May 27, 2026. Following the assessment of interest, the government anticipates issuing a formal Request for Proposal in early June 2026 via SAM.gov, outlining detailed requirements and evaluation criteria for a firm fixed-price contract award. The contracting office encourages participants to ensure proper registration in the System for Award Management (SAM) and notes that all communications must be directed in writing to the designated contracting officer. A site visit will be offered as part of the formal solicitation process to provide potential contractors an opportunity to assess the project site and scope.
