2026 Upper Development, Dam No. 1 Rehabilitation

The Idaho Falls Power is seeking bids for the 2026 Upper Development, Dam No. 1 Rehabilitation project. The project involves removing the existing hydraulic lines, fabricating and installing a new hydraulic system, and replacing existing pipe supports. The new piping will be made of 1-1/4 inch Stainless Steel with a minimum working pressure of 3,100 psi. The project also includes spot treating the upstream and downstream coatings and other surfaces, applying new coatings to prepared surfaces, and removing and replacing existing seals and seal hardware. The project is contingent on Idaho Falls Power's approval from the Federal Energy Regulatory Commission and will take place after a coffer dam has been installed and the water has been drained between the coffer dam and Dam No. 1. • The project requires the removal of existing hydraulic lines and the fabrication and installation of a new hydraulic system. • The new piping will be made of 1-1/4 inch Stainless Steel with a minimum working pressure of 3,100 psi. • The project includes spot treating the upstream and downstream coatings and other surfaces. • The project includes applying new coatings to prepared surfaces. • The project includes removing and replacing existing seals and seal hardware.
