Chic 240631 construct water treatment plant and maintenance building

The National Park Service Denver Service Center is seeking Design-Build Construction Services to replace the existing water treatment plant and construct a new maintenance building at Chickasaw National Recreation Area in Sulphur, Oklahoma. The water treatment plant replacement will increase design capacity from 25,000 to 43,000 gallons per day and address current maintenance issues, while the new facility will be a 3,490 square-foot maintenance building designed to consolidate facilities and improve emergency response capabilities. This will be a two-phase Design-Build procurement requiring prospective offerors to be registered in the System for Award Management (SAM) and to provide Bid, Performance, and Payment Bonds. The award will be determined through a best-value trade-off process that evaluates technical approach, management approach, schedule, key personnel, and safety factors. The full Request for Proposals (RFP 140P2025R0014) is anticipated to be issued electronically via SAM.gov on or after July 23, 2025, with responses due by August 25, 2025.

This procurement is designated as a Total Small Business set-aside under NAICS code 236220 for Commercial and Institutional Building Construction. The total project value exceeds $10 million and will be awarded as a Firm-Fixed-Price contract with an 810-calendar-day performance period. No current incumbents or contractors are identified in the pre-solicitation notice. The contract structure emphasizes the significant scope of work involving both water infrastructure improvements and new construction, with the extended timeline reflecting the complexity of the design-build approach. Small businesses interested in this opportunity must demonstrate capability in both water treatment facility construction and maintenance building projects to be competitive in this substantial federal construction contract.
