2503SA BCWRRF and Lab HVAC Improvements

This project involves the removal and installation of HVAC equipment, ductwork, valves, pumps, and piping at the Greene County Sanitary Engineering Department facility located at 667 Dayton-Xenia Road, Xenia, Ohio. The scope includes draining and flushing of hot water piping, system testing and balancing, and all necessary electrical and control connections, requiring full compliance with applicable industry standards such as ASTM, AISC, AWS, and NFPA. Materials must be delivered with manufacturer labels indicating specifications, fire hazard indexes, and maximum use temperatures, and must remain in original packaging until installation. Stainless steel components require pickling, passivation per ASTM A380, and the use of graphite-free anti-seize compounds on bolting. All equipment must feature permanent nameplates made of brass or rigid black plastic with legible engraved markings, and valves over three inches require engraved brass or 316 stainless steel tags with size, pressure ratings, and manufacturer details. Bar-code identification nameplates are mandatory for all equipment to support maintenance and inventory tracking. The contract is structured under a local ARTICLE-based format rather than federal FAR clauses, with provisions for change orders, field orders, and alternates to accommodate modifications. The bid deadline is June 9, 2026, and the bid must be submitted either electronically via BidExpress or as a hard copy. The estimated contract value is approximately $155,000, with pricing broken into bid items such as mobilization, traffic control, fire hydrant installation, and copper service line installation. Evaluation for award will prioritize the “lowest and best” bid, giving substantial weight to the bidder’s work history, including prior experience on similar projects, timeliness, cooperation with the owner and design team, and claims history. The contractor must hold a valid Ohio contractor license, ensure supervisory personnel have either three years of trade experience or state licensure, and certify compliance with Ohio’s Drug-Free Workplace Act and prevailing wage laws. Insurance requirements mandate primary, non-contributory coverage with a waiver of subrogation in favor of Greene County, and coverage must remain active for one year after final payment. All work must adhere to local building codes, and inspections may occur at the manufacturer’s facility, shop, or project site, with the contractor responsible for arranging and paying for all required tests and certifications, including Greenguard and AISC certifications.
