UNSPSC 73181906: Projection welding services

UNSPSC 73181906 Projection welding services (Commodity) spans field and shop welding, fabrication, and repair work across water, transit, utility, education, and municipal infrastructure assets. State and local governments procure this code for on-call and periodic welding maintenance on specialized equipment—rail systems, water treatment infrastructure, bridge railings, tank components, gate and door systems, and facility metalwork—where certified welders perform repairs to ensure structural integrity and regulatory compliance. The issuing bodies range across transit authorities (Charlotte Area Transit System, Bay Area transit districts), municipal water departments and water treatment utilities (Alameda County Water District, Austin Water, Tampa Water, New Smyrna Beach Utilities), county and municipal facilities and public works operations (Hillsborough County, Greenville County, City of Atlanta), school districts (Austin Independent School District, Mt. San Antonio Community College District), and special-purpose districts (North Texas Municipal Water District). Recent solicitations show sustained activity with no clear concentration among a single jurisdiction type—water utilities and transit systems appear frequently, but municipalities, counties, and school districts also compete for these contracts.

Geographic activity spans Texas (Austin, North Texas, Tampa), California (Alameda County, Mt. San Antonio, Santa Clara), North Carolina (Charlotte), Georgia (Atlanta, DeKalb County, Greenville County), Connecticut, and Florida across recent postings from January through July 2026. Representative recent opportunities include the Charlotte Area Transit System's Blue Line track welding services RFP (response due August 20, 2026 / rebid version due March 6, 2026), covering turnkey maintenance and repair in compliance with Federal Railroad Administration and Maintenance of Way standards; the City of Tampa's Water Department ITB for as-needed welding and fabrication services on water infrastructure with an estimated contract value of $70,000 and a 5% bid discount for certified Small Local Business Enterprises (response due July 31, 2026); the Alameda County Water District's IFB for on-call field and shop welding requiring 1,500 field hours and 500 shop hours annually under a two-year base term (response due May 2, 2026); and the Hillsborough County Board of County Commissioners' ITB for mobile welding services at solid waste facilities with an estimated value of $207,429.10 over a term through July 31, 2028 (response due June 29, 2026). Greenville County's RFP for Laurel Creek Pedestrian Bridge railings (response due August 5, 2026) exemplifies specialized welding scope—244 linear feet of bridge railings requiring certified welders holding current AWS D1.1 certifications and weathering steel conforming to ASTM specifications, with performance bonding and liability insurance ($1 million per occurrence / $2 million aggregate) required. These procurements consistently demand current welding certifications (AWS, 6G pipe certification, TIG/MIG/arc methods depending on materials), experience serving comparable entities, and robust insurance and bonding structures; several include set-asides or preferences for small, local, and disadvantaged-owned firms. Contract terms typically span one to three years with renewal options; pricing structures range from hourly labor rates to lump-sum or unit-price arrangements with firm pricing in year one and CPI-U-capped escalation thereafter.
