Rio Consumnes Correctional Center New Potable Water Tank

Sacramento County is soliciting bids for design and construction of a new 350,000-gallon potable water prestressed concrete tank at Rio Consumnes Correctional Center, with sealed bids due October 15, 2026 at 2:00 p.m. and a mandatory pre-bid meeting on September 16, 2026 at 10:00 a.m. A Class A California contractor license is required, and the project is subject to prevailing wage requirements under California Labor Code sections 1720 and 1770.

The tank contractor must meet stringent minimum qualifications: at least ten years of experience designing and constructing AWWA D110 Type I strand-wound, prestressed concrete tanks, with five of those ten tanks located in seismic zones with mapped spectral response acceleration (Ss) of 0.626g or greater and in successful service for at least five years. The contractor must submit sealed design drawings and calculations by a California-registered engineer suitable for building permit approval.

Scope includes site preparation, construction of a gravel access road surrounding the tank, installation of water lines and electrical conduit connecting the tank to the existing water treatment facility, and all associated civil, structural, and electrical work. The tank must be 46 feet inside diameter with 30-foot water depth, designed per AWWA D110, ACI 350.3, and ASCE 7-10 standards. The contractor or designated tank prestressor must operate two operable automated strandwrapping systems and two operable automated shotcrete machines with continuous electronic monitoring capability.

The estimated construction cost is $4,906,288. Contract duration is 380 calendar days from execution. Liquidated damages are $4,778 per calendar day for delays beyond completion. The three lowest bidders must submit escrow bid documents. Bid security of ten percent is required as a bid bond, certified check, or cashier's check; performance and payment bonds each equal 100 percent of contract price must be provided by the successful bidder.

All personnel entering the secure facility require background security clearance via the process detailed in Appendix C, submitted at least five business days prior to entry. Contractors must comply with California's CALGreen waste diversion mandate (65 percent minimum recycling of construction and demolition debris), submit waste management and erosion-control plans, and adhere to all facility regulations. Questions on the bid are due September 30, 2026 at 2:00 p.m., with County responses due October 7, 2026.
