Effluent 66-Inch Valve Replacement

The City of Riverside Public Works Department is soliciting bids for the removal and replacement of a 66-inch butterfly valve at the RWQCP in Riverside, California. The project involves the installation of a pre-purchased valve, requiring the contractor to handle site preparation, field measurements, bypass pumping, and the installation of flexible couplings and nut-bolt gasket kits. Work must be completed within twenty working days from the Notice to Proceed, with strict operational constraints limiting shutdowns to a maximum of ten hours and requiring a two-week grace period between shutdowns to stabilize plant levels. The estimated contract value is 163,000 dollars. The contract will be awarded to the lowest responsive and responsible bidder. Qualification requirements include the submission of three completed projects comparable in scope to valve installation, a notarized bidder's bond for at least ten percent of the proposal amount, and registration with the Department of Industrial Relations. Successful bidders must provide performance and payment bonds for 100 percent of the contract price and comply with prevailing wage rates and non-discrimination standards. Final payment is contingent upon the submission of approved red-lined plans and the completion of all work according to City safety and quality standards.
