The Department of the Interior's National Park Service is seeking a small business contractor to rehabilitate the irrigation system at the John Muir National Historic Site in Martinez, California. The project requires a comprehensive replacement of an existing 15-30 year old irrigation system covering 9 acres of historic landscape, including orchards, gardens, and areas surrounding the historic John Muir House. Contractors must provide full project management including mobilization, labor, supervision, materials, equipment, transportation, site rehabilitation, clean-up, and demobilization. All questions regarding the solicitation must be submitted via email to Brian Roppolo at brian_roppolo@nps.gov no later than May 15, 2025, with responses to be posted on SAM.gov. Proposals are due by 12:00 P.M. Pacific Standard Time on May 15, 2025, with only emailed submissions accepted.

The solicitation is exclusively set aside for Small Business concerns under NAICS code 238220, with a small business size standard of $19.0 million. The project's construction magnitude is between $100,000 and $250,000, with a performance period from June 1, 2025, to January 17, 2026. Contractors will be required to utilize Hunter irrigation equipment, including a two-wire controller, WiFi module, remote control kit, and wireless weather sensor. The work will involve reconnecting two historic hand-dug, rock-lined wells and using two existing water meters located at the park entrance and near the Martinez Adobe. Certified irrigation technicians with landscape irrigation installation experience are expected to perform the work, adhering to multiple industry standards and codes. The project will require precise installation procedures, quality control testing, and a final system demonstration to National Park Service maintenance personnel.
