AI overview

Idaho Falls Power is accepting proposals for the rehabilitation of Dam No. 1 at the Upper Development. The scope of work includes the removal of existing hydraulic lines and the fabrication and installation of a new hydraulic system, including all material, labor, and consumables. New piping must be 1-1/4 inch stainless steel with a minimum working pressure of 3,100 psi, and existing pipe supports are to be replaced. The contractor will also be responsible for spot-treating upstream and downstream coatings and other surfaces by removing rust and flaking coatings, then applying original coatings to prepared surfaces, including cable trench covers.

Additionally, existing seals (side, bottom sill, and middle) must be removed and replaced with new seals, along with all associated seal hardware. The work is contingent upon approval from the Federal Energy Regulatory Commission (FERC), which Idaho Falls Power is pursuing. The project will proceed only after a cofferdam has been installed and the water between the cofferdam and Dam No. 1 has been drained, ensuring a dry work environment.

Key dates include a pre-bid meeting on July 7, 2026 at 1:00 PM MST, and a bid submission deadline of July 16, 2026 at 1:00 PM MST. Proposals are to be submitted to Jason Cooper. The solicitation number is IFP 26-21-2, and the project is classified as a construction bid. The publication date was June 23, 2026, with the bid opening occurring immediately after the submission deadline.

Interested contractors must review the full set of related documents available through the City of Idaho Falls bidding portal. The work involves specialized hydraulic and coatings work on a FERC-regulated hydroelectric dam, requiring experience with similar hydro-mechanical and structural rehabilitation projects. No budget or pricing information has been disclosed in this posting.
