About this file

Written by GovTribe AI ·

This solicitation seeks proposals to refurbish butterfly valves and associated systems for two generator units at Fort Peck Dam in Montana. The U.S. Army Corps of Engineers will award a contract to refurbish eighteen-foot diameter spiral case inlet butterfly valves, valve operators, bypass piping and valves, spiral case and tunnel drain valves, valve access hatches and platforms, hydraulic power units and controls. Nondestructive examination of penstock tunnels will also be required. The butterfly valves will be refurbished in-place to improve internal bypass leakage, address component end-of-life issues and improve system reliability. Refurbishments will include replacing bronze disc seals and hardware with stainless steel, conducting nondestructive testing, sandblasting and recoating discs, and replacing shaft and thrust bearings. The refurbished penstock systems should provide 50 years of functional service with limited maintenance. Optional bid items include exterior penstock paint repairs and valve disc weld repairs. Bidders must meet all licensing and certification requirements and provide proper personal protective equipment for the project duration. The solicitation closes 27 February 2023.
