UNSPSC 73181000: Machining services

UNSPSC 73181000 Machining services is a Class code under which state and local governments procure metal machining, welding, fabrication, and related equipment repair services, primarily for infrastructure maintenance, water and wastewater system components, and vehicle and equipment restoration. Recent solicitations show that buying bodies order precision machine shop work (turning, boring, milling, polishing, and bushing operations on pumps and motors), welding and fabrication of structural steel and dump bodies, sand blasting and painting of heavy equipment, and rebuilding of clarifier and thickener mechanisms at water treatment facilities. The issuing bodies include county government (Palm Beach County, DeKalb County), municipalities (City of Atlanta), transit authorities (Utah Department of Transportation, Orange County Transportation Authority), and special-purpose districts (Macon Water Authority). Utah Department of Transportation has been a repeat buyer, issuing multiple regional contracts for welding and fabrication services and regional sand-blasting and painting work across its five geographic areas in the state.

Recent activity is most concentrated in Utah and Georgia. The Macon Water Authority issued an Invitation to Bid (ITB) due October 20, 2026, for rebuild of gravity thickeners and clarifiers at Rocky Creek Water Reclamation Facility, with mandatory pre-bid attendance on October 6, 2026, and a 51 percent self-performance requirement for the general contractor. The Utah Department of Transportation posted multiple IFBs and RFPs for regional sand-blasting, painting, welding, and fabrication services, with geographic restrictions (e.g., bidders within 30 miles of zip code 84501 for UDOT Region 4), response deadlines in late August and early September 2026, and multiple anticipated awards. Palm Beach County issued an IFB due June 24, 2026, for off-site precision machine shop services (milling, boring, turning, welding, fabrication) supporting five county water and wastewater facilities, with a Small Business Enterprise price preference and a 12-month contract term with estimated expenditure of $188,750. The Orange County Transportation Authority requested quotes due June 2, 2026, for a Scotchman 50-ton ironworker fabrication machine with delivery and installation within 120 days at an estimated value of $35,772.
