Replacement of a Fire Supp System at YOSE Museum

The National Park Service (NPS) is seeking a small business contractor to replace the fire suppression system at the Yosemite Valley Museum and District Ranger Office located in Mariposa County, California. The project involves removing the existing Marioff High Pressure Water Mist System and installing a new system, including replacing nitrogen hoses, recertifying and hydro-testing nitrogen tanks, and installing a new jockey pump. Contractors must perform pressure tests in compliance with National Fire Protection Association (NFPA) standards and provide a passed inspection report. The solicitation (140P8525Q0041) requires potential bidders to provide all necessary mobilization, labor, supervision, materials, equipment, and transportation for the project. An organized site visit is scheduled for June 4, 2025, at 2:00 PM PDT, and interested contractors must RSVP with the contracting officer representative.

The contract is exclusively set aside for small businesses with a contract value between $100,000 and $250,000. The performance timeline is relatively tight, with 10 calendar days to commence work and 30 calendar days to complete the entire project after receiving the notice to proceed. The project site has significant hauling restrictions, with vehicles over 45 feet prohibited and one-way controlled traffic in effect 20 miles east of Mariposa County due to ongoing rockslide repairs. The work will be performed at a historic 1924 building housing valuable museum collections and a research library, making the fire suppression system critical for protecting the building, its contents, staff, and visitors. The contract falls under the NAICS category 238220 for Plumbing, Heating, and Air-Conditioning Contractors and PSC category J012 for Maintenance/Repair/Rebuild of Fire Control Equipment. Proposals are due by June 20, 2025, and the point of contact is Stephanie Bartholomew, Facility Operations Specialist, who can be reached at 209-379-1054.
