Boiler Retube Repair for a Cleaver-Brooks CB200-250-150ST

The McAlester Army Ammunition Plant in Oklahoma is seeking qualified small businesses to respond to a Request for Information regarding the repair of fire tubes on two Cleaver-Brooks CB200-250-150ST boilers located in Building 165. This solicitation, identified as W519TC26Q3178, is a Total Small Business Set-Aside under NAICS Code 811310 and is intended to identify capable vendors prior to potential award. The work requires a certified boiler mechanic to remove damaged fire tubes and install government-furnished replacements, performing flush patching or tube ligament repairs as needed, with all welding conducted in compliance with ASME codes. The contractor must mobilize within thirty calendar days of notification and complete all work during normal business hours Monday through Friday, excluding federal holidays, unless otherwise authorized. All personnel must be U.S. citizens and pass a background check to gain access to the secure facility, and coordination of gate entry and escorts must occur at least two business days prior to arrival. The performance location is specifically at the McAlester Army Ammunition Plant in McAlester, Oklahoma, with a zip code of 74501. The contractor is responsible for supplying all specialized tools, piping, hardware, and electrical components required for the job, while the government will provide and stage the replacement fire tubes. Work must include a hydrostatic test to verify structural integrity, followed by formal closing and sealing of both the waterside and fireside of the boilers. Daily housekeeping is required, with all contractor-generated waste disposed of in government-provided dumpsters. Compliance with OSHA guidelines and USACE EM 385-1-1 safety standards is mandatory, and the contractor assumes full liability for any damage caused by their personnel or equipment. No pricing, line items, or evaluation criteria are included as this is an RFI stage to gauge industry interest and capability, not a formal solicitation for bids. All responses must be submitted by June 29, 2026, to Regina L. Gibson at regina.l.gibson7.civ@army.mil.
