Backflow, valves and chiller replacements

The Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) is procuring mechanical services for backflow preventers, valve replacements, and chiller pipe repairs at their National Laboratory Center in Beltsville, Maryland. The contract requires installation of four backflow preventers (two 8-inch, one 4-inch, and one 1.5-inch Zurn/Wilkins or equivalent units), replacement of two 8-inch main gate valves on the effluent side, and repair of up to 8 feet of leaking 10-inch schedule 40 weld pipe in the chiller room ceiling. The procurement will use a Lowest Price Technically Acceptable (LPTA) evaluation method, where only the lowest-priced quote meeting technical requirements will be awarded. Contractors must submit two volumes: a technical volume demonstrating capability and past performance (6 pages maximum each) and a separate pricing volume. The solicitation closing date was extended to September 16, 2025 at 3:00 PM ET, with an optional site visit conducted on September 11, 2025, and contractors required to complete police check inquiries for facility access.

This opportunity is designated as a 100% small business set-aside under NAICS code 238220 (Plumbing, Heating, and Air-Conditioning Contractors) with a size standard of $19 million. The contract will be structured as a firm fixed-price purchase order with a performance period from September 15, 2025 to September 14, 2026, though the actual work is expected to be completed within 180 days of award. All work must be performed during off-hours to minimize disruption to government operations, and the contractor must provide equipment within 6 weeks of award. The project includes comprehensive safety requirements, including the use of smoke eaters during welding operations and fire safety equipment, with all work monitored by ATF building engineers. The contractor must provide a one-year warranty on all aspects of the project and submit weekly progress reports throughout the performance period.
