UNSPSC 73181900: Welding and brazing and soldering services

UNSPSC 73181900 Welding and brazing and soldering services is a Class code covering repair, fabrication, and installation work performed on site and at contractor facilities across diverse equipment and infrastructure. State and local governments buy welding services primarily for equipment maintenance and repair (mobile welding at solid waste facilities, water treatment plants, transit authorities), infrastructure restoration (storage tank recoating, bridge railings, pedestrian walkways), educational lab upgrades, and vehicle fleet servicing. Issuing bodies span the full range of state and local procurement: state departments of transportation and wildlife resources, cities and counties (Tampa, Austin, Huntsville, Hillsborough, Statesboro, Union City), water utilities and wastewater treatment agencies, school districts and community colleges, transit authorities (Charlotte Area Transit System), university facilities departments, and special-purpose districts (North Texas Municipal Water District). The geographic spread includes active procurement in Texas, Utah, Florida, Georgia, California, Rhode Island, South Carolina, North Carolina, and Oregon, with Utah showing particular concentration through multiple UDOT regional contracts and geographic-restricted bids for equipment refurbishment and plow repair.

Recent representative opportunities illustrate the variety. The City of Huntsville, Texas issued an IFB (Bid NO. 27-05, due October 27, 2026) for restoration and recoating of a half-million-gallon welded steel water storage tank including pit welds, structural repairs, and surface preparation to near-white blast cleaning standards, with a 90-calendar-day performance window and liquidated damages of $1,500 per day. Mt. San Antonio Community College District solicited bids (ITB 2026067, due July 16, 2026) for purchase and installation of forty-seven flexible vent extraction arms in an educational Welding Lab at Walnut, California, requiring California Contractor's License classification C-20 and DIR registration with a 3% Disabled Veteran Business Enterprise participation goal. The Utah Department of Transportation issued multiple RFPs and IFBs for regional welding and fabrication services across five geographic regions (due August 21 and September 3, 2026) and a Region 4–specific IFB restricted to bidders within 30 miles of zip code 84501 covering sand blasting, painting, and welding of dump bodies, snowplows, and material spreaders. Hillsborough County issued an ITB (ITB-26-00389, due September 16, 2026) for mobile welding and fabrication services at solid waste facilities with four-hour response times during business hours and emergency 24-hour completion requirements, estimated at $207,429.10 over three years. The State of Rhode Island Division of Purchases established a Master Price Agreement (MPA 433, through April 2, 2031) for electrical and gas welding services statewide with pass-fail qualification, prevailing wage requirements, and 0.33% contract administrative fees. Procurement activity reflects strong demand for responsive on-call services, specialized certifications (AWS, stainless steel, confined-space entry), and performance bonds across jurisdictions.
