Construction Services: DCWWTP Primary Sedimentation Basin Rehabilitation Project

The City of Roseville is soliciting proposals for the Dry Creek Wastewater Treatment Plant Primary Sedimentation Basin Rehabilitation Project under solicitation 08-177. This competitive negotiation process seeks a qualified contractor to rehabilitate a 220-foot-long section of the primary sedimentation basin consisting of four trains. The primary objectives are to restore watertightness, mitigate corrosion and structural degradation, and extend the service life of the facility. The scope of work includes replacing expansion joints, installing miscellaneous metals and materials, and the operational integration of the chain and flight mechanized clarifier system. The project is structured as a Guaranteed Maximum Price contract and includes a mandatory project allowance of 1,000,000 dollars for additional structural rehabilitation, such as concrete resurfacing and crack injection. The contract requires the selected proposer to provide 100 percent performance and payment bonds and maintain a valid Contractor State License Board license. All work must adhere to ASTM, SSPC, ACI, and AWWA standards, with specific requirements for near-white metal blast cleaning and high solids epoxy coatings. The project timeline specifies that all four refurbished basins must be operationally ready within 252 consecutive calendar days from the Notice to Proceed, with a 15-working-day allowance for weather delays. A one-year warranty is required following final completion. Proposals are due by October 27, 2026, and will be evaluated based on a 100-point scale considering the most advantageous proposal to the City, with potential interviews for top candidates.
