16292 Steam Boiler Replacement

The Air Force Sustainment Center seeks replacement of the existing steam heat exchanger system in Building 1515 at Hill Air Force Base with a decentralized gas-fired hot water boiler system, with proposals due October 19, 2026 and questions due October 5, 2026. This is a Total Small Business set-aside.

Place of performance is Hill AFB, UT 84056 (6137 Wardleigh Road, Building 1515, 309th SWEG). The estimated award value is between $1,000,000 and $5,000,000, on a Firm Fixed Price basis. The period of performance is weather-dependent and tied to the base steam schedule; design, specifications, and material ordering must complete before steam shut-off (typically April–May), with construction commencing 60 calendar days after steam shut-off, targeting completion by June 30, 2026.

The project is a design-build scope requiring complete mechanical, electrical, and controls engineering; demolition of existing steam and condensate systems; specification and installation of three new high-efficiency gas-fired hot water boilers (RBI Futera III or approved equivalent) with primary/secondary configuration and 4-port hot water buffer tank; natural gas piping and hydronic installation; BACnet-compatible controls integration into the facility's Direct Digital Control/Energy Management Control System; and full commissioning including testing, adjusting, and balancing. Building 1515 comprises four mechanical rooms, each with its own steam-water exchange system. The contractor may propose alternative capacity configurations including N+1 redundancy with 50% sizing per boiler or partial redundancy with 1/3 sizing per boiler. Design submittal (65%) is due 30 calendar days after award; 100% design submittal is due 60 calendar days after award. All work must comply with UFC standards, International Building Code, EPA regulations, EM 385-1-1 safety requirements, and Hill AFB Installation Facilities Standards for natural gas systems, mechanical systems design, and electrical infrastructure. The contractor must provide comprehensive warranties: one-year construction, ten-year boiler heat exchanger, twenty-year thermal shock, and one-year general parts and components. Contractors must hold active SAM registration with a CAGE code. The NAICS code is 238220 (Plumbing, Heating, and Air-Conditioning Contractors); PSC is J045. Award will be made on a Lowest Price Technically Acceptable (LPTA) basis, evaluating preliminary design submission and recommendations, contractor experience (minimum ten consecutive years with three completed similar projects within the last five years), and price. Evaluation considers greater system redundancy, higher energy efficiency, reduced operational risk, and stronger past performance. All questions must be submitted to TSgt Jonathan Graham (jonathan.graham.11@us.af.mil) by 1500 MT October 5; offers are due by 1200 MST October 19 via email. Mandatory site visit attendance on August 12, 2026 at 0900 was required for bid eligibility. A Limited Inspection Report dated August 4, 2026 found no regulated asbestos-containing materials in steam line samples but identified six lead-based paint positive readings on metal pipes and valve handles requiring segregation or abatement prior to removal. Davis-Bacon prevailing wage rates apply, with key classifications including plumber/pipefitter at $46.10/hour plus $15.83 fringe and sheet metal worker at $46.79/hour plus $14.89 fringe (effective May 18, 2026).
