YOSE 228647 Rehabilitate Tuolumne Meadows Water Distribution System.

The Department of the Interior's National Park Service is seeking to rehabilitate the water distribution system at Yosemite National Park's Tuolumne Meadows area through a comprehensive infrastructure project. The Sources Sought Notice outlines a complex water system upgrade involving replacement of 37,940 linear feet of water lines, upgrading a water tank from 100,000 to 200,000 gallons, replacing 14 fire hydrants, and installing approximately 60 water meters. The project is classified under NAICS code 237990 for Other Heavy and Civil Engineering Construction, with a small business size standard of $45M. Interested firms must submit detailed company information, including business classification, bonding capacity, project experience, and capability statements by April 1, 2025, at noon Mountain Time. The National Park Service will use these submissions to evaluate potential contractors and determine whether a small business set-aside is appropriate for the forthcoming Request for Proposals.

The anticipated construction value exceeds $10 million, with a projected performance period of 1,068 days, though actual construction will be limited to the summer season between mid-May and late October. The project will require bid, performance, and payment bonds, and includes strict environmental and archaeological site protection requirements. The water distribution system currently serves visitor use areas and National Park Service buildings, providing an average of 34,000 gallons of potable water daily, with a maximum daily capacity of 73,000 gallons. The National Park Service plans to issue a formal Request for Proposals in Summer 2025, with the ultimate goal of modernizing and expanding the water infrastructure in the Tuolumne Meadows area. Potential contractors should be prepared for a complex project that requires specialized expertise in heavy civil engineering and environmental conservation.
