UNSPSC 73152107: Machining equipment rebuild and refurbishment service

Rebuilding and refurbishment of machining equipment beyond normal maintenance and repair

UNSPSC 73152107, Machining equipment rebuild and refurbishment service, is a Commodity code under which state and local governments solicit repair, rebuild, and refurbishment of industrial and commercial mechanical equipment, particularly HVAC systems, chillers, cooling towers, and ancillary mechanical infrastructure. The code reflects work that goes beyond routine maintenance to encompass complete system rebuilds, component replacement, technical refurbishment, and restoration to operational specifications. Recent solicitations show state and local buyers purchasing chiller rebuilds with Freon recovery and cleaning, cooling tower replacement with stainless-steel fabrication, energy recovery ventilator component replacement, rooftop unit replacement with controls integration, and specialized HVAC equipment refurbishment performed by factory-certified technicians. Issuing bodies include higher-education institutions (Angelo State University), county governments (Dougherty County, Gwinnett County, Henry County, DeKalb County School District), city governments (Albany, Detroit, Bartow, Santa Monica, Augusta), fire and rescue authorities (Tualatin Valley Fire & Rescue), water and wastewater districts (Madison Metropolitan Sewerage District, Kissimmee Utility Authority, Sacramento County Water Agency), and school districts. Repeat buyers and high-activity jurisdictions include Gwinnett County (multiple HVAC replacement projects at pump stations and fire stations), city of Albany (chiller and air-handling-unit replacement), and Detroit (design-build HVAC upgrades at multiple municipal facilities).

The code spans active geographic markets including Georgia (Gwinnett County, DeKalb County, Henry County, Augusta, Albany), Florida (Dougherty County, Hillsborough County, Pinellas County Schools, Valencia College, Kissimmee Utility Authority), Texas (Angelo State University, Giddings State Juvenile Correctional Facility, Tualatin Valley Fire & Rescue in Oregon, Midwestern State University), Michigan (Detroit), California (Santa Monica, Sacramento County), and other states. Representative recent opportunities include the City of Albany's RFP for HVAC chiller rebuild and cooling tower installation at Dougherty County Jail (RFP #27-031, due November 13, 2026), requiring Trane-certified technicians, 5-year warranty, and specialized cooling-tower refurbishment; Tualatin Valley Fire & Rescue's RFQ for on-call HVAC services across 34 fire stations (SR3414200018196, due November 2, 2026), offering unit-rate pricing for labor and materials; DeKalb County School District's RFP for HVAC water treatment services across 98 facilities (RFP 27-812, due October 22, 2026), covering cooling-tower and chilled-water treatment; and Gwinnett County's sealed-bid procurement for pump-station grinder and slide-gate replacement with HVAC infrastructure modifications (BL152-26, due November 20, 2026). The code shows strong activity in higher-education, municipal facilities, water-treatment, fire-rescue, and school-district segments, with contracts typically spanning one to five years and incorporating prevailing-wage requirements, multi-award structures on rotating task-order distribution, performance bonds, comprehensive insurance, and factory-training or certification mandates.
