UNSPSC 73181907: Brazing services

UNSPSC 73181907 Brazing services (Commodity) encompasses field and shop welding, brazing, and metal fabrication services that state and local governments procure to repair and maintain infrastructure, equipment, and facilities. The code captures a broad range of metal-joining work: portable and shop welding on water system vaults and piping, stainless steel welding and plasma cutting for treatment plant access plates, rail track welding for light-rail systems, structural steel repairs on pedestrian bridges, and general-purpose welding services for municipal solid waste and transportation equipment. Issuing bodies span departments of public works and water utilities, transit authorities, school districts, community colleges, and county facilities departments. Work is solicited as both as-needed on-call contracts with hourly billing and fixed-price project work, and the code reflects active procurement across all public-sector tier sizes—from small municipal utilities to large county and city departments and independent school districts.

Recent activity concentrates in Texas, California, Georgia, North Carolina, and Florida. The City of Tampa's Water Department posted an ITB in June 2026 for as-needed welding and fabrication on black-iron steel water infrastructure with a $70,000 estimated value, sheltered to certified Small Local Business Enterprises at a 5% bid discount. Greenville County (South Carolina) issued an RFP in July 2026 for fabrication and installation of 244 linear feet of weathering steel bridge railings on the Swamp Rabbit Trail, requiring AWS D1.1-certified welders and demanding performance bonds and $1 million liability insurance. The Charlotte Area Transit System posted a rebid in January 2026 (due March 6) for comprehensive Blue Line track welding services including rail end, thermite, and frog welding under FRA and MOW standards, with 24/7 emergency on-call mobilization. The Alameda County Water District solicited on-call field and shop welding with an estimated 1,500 annual field hours and 500 shop hours, firm labor rates for two years plus three one-year renewals, and a March 31, 2026 questions deadline. Hillsborough County (Florida) issued an ITB in June 2026 for mobile welding services at four solid waste facilities with estimated value $207,429 through July 2028, requiring AWS certifications in TIG, MIG, and Arc with four-hour standard response and one-year warranty. Set-asides and preferences appear in several recent awards—SLBEs in Tampa, DBE goals in Atlanta BeltLine Phase 2 on-call services (30% participation goal including structural welding), and Texas local-vendor preferences in school district gate and door maintenance contracts that bundle welding and fabrication with mechanical repair work.
