UNSPSC 72151000: Boiler and furnace construction and maintenance services

The installation and main encasement of boiler and furnace systems and components

UNSPSC 72151000 Boiler and furnace construction and maintenance services, a Class code, encompasses preventive maintenance, repair, testing, inspection, and replacement work on boiler systems serving state and local government facilities ranging from schools and municipal buildings to correctional institutions, hospitals, and utility plants. Recent state and local solicitations show a mix of full boiler replacements, system upgrades, and ongoing maintenance contracts covering everything from routine seasonal servicing to emergency after-hours repair availability. Work involves both standard atmospheric and water tube boilers, associated ancillary equipment such as feed pumps and deaerators, and integration with facility management systems in operational settings.

Issuing bodies soliciting under this code span school districts, county governments, municipal departments, state agencies, and special-district authorities. Repeat buyers include the County of Orange and California Department of General Services, both seeking multiple boiler maintenance contracts across their portfolios. Recent opportunities originate primarily in California, Massachusetts, Connecticut, Georgia, Minnesota, Texas, and Florida, with California showing the highest concentration of activity—including CDCR statewide contracts at 33 locations, county health facilities, and Caltrans offices. Representative recent solicitations include the California Department of Corrections and Rehabilitation's boiler maintenance, inspection, calibration, and repair services IFB (bids due November 9, 2026) spanning all 33 participating CDCR locations statewide with mandatory walk-throughs and a 3% minimum DVBE participation requirement; the County of Orange Sheriff-Coroner's RFP for testing, insulation, and repair of boilers and steam generators at five Sheriff facilities (proposals due October 14, 2026 with 5% OCLSB/DVBE preference); the City of Worcester, Massachusetts boiler replacement at the Library/DPF facility (bids due October 14, 2026); and the California Department of General Services boiler maintenance services at the Joe Serna Jr. building in Sacramento under a 3% DVBE participation mandate with incentive premiums (bids due October 27, 2026). Licensed boiler contractors holding California C-4 or equivalent state credentials and ability to meet prevailing wage and emergency-response requirements remain competitive; several jurisdictions impose set-asides or preferences for SBE, DVBE, and local small-business certification.
