Description

The City of Riverside is seeking bids to replace a 66‑inch butterfly valve at its Regional Water‑Quality‑Control Plant. The city has already purchased the new valve; the contractor must remove the existing valve, install the new valve, and provide all necessary couplings, gaskets, and temporary steel blocking plates. Work must be completed within a 20‑day contract period after the Notice to Proceed, with a maximum shutdown of 8 hours per isolation event and a two‑week grace period between shutdowns. The project includes re‑bar scanning, installation of anchoring for the temporary plate, and testing of the valve to verify proper operation.
