UNSPSC 73181901: Arc welding services

UNSPSC 73181901 Arc welding services is a Commodity code that covers on-site and mobile welding repair, fabrication, and maintenance work performed by state and local governments across water infrastructure, equipment servicing, facility renovations, and transit maintenance. State and local governments soliciting under this code purchase shielded metal arc welding (SMAW), gas metal arc welding (GMAW), and gas tungsten arc welding (GTAW) services, often bundled with cutting, grinding, brazing, and plasma operations on steel, stainless steel, and aluminum. Recent opportunities show municipalities and special-purpose districts (water departments, transit authorities, county solid waste operations, community colleges, and state procurement offices) using RFPs, RFQs, ITBs, and IFBs to procure both on-call annual contracts and project-specific welding. The City of Tampa's Water Department (ITB 26-P-00401, bids due August 21, 2026) sought as-needed mobile welding and fabrication for water vault infrastructure with a 5 percent SLBE bid discount capped at $10,000 on a $70,000 estimated value. Hillsborough County Board of County Commissioners (ITB-26-00389, bids due September 16, 2026) requested mobile welding and fabrication services for solid waste equipment at four facility locations across a three-year term with a $207,429.10 estimate. The City of Huntsville, Texas (Bid NO. 27-05, bids due October 27, 2026) solicited restoration and pit welding of a half-million-gallon welded steel water storage tank with mandatory site visit on October 15, 2026, requiring AWS certifications, confined-space entry compliance, and stainless steel welding qualifications.

Activity concentrates in Texas, Florida, Georgia, California, and the Carolinas, with secondary volume across Oregon and Rhode Island. Issuing bodies span city water and wastewater departments (Tampa, Austin, Huntsville), county solid waste operations (Hillsborough, DeKalb), transit authorities (Charlotte Area Transit System—CATS Blue Line track welding, rebid #3, proposals due August 20, 2026), community college districts (Mt. San Antonio Community College District, installation of forty-seven flexible vent extraction arms in welding lab with 3% DVBE goal, bids due July 16, 2026), state procurement offices (Rhode Island Division of Purchases establishing Master Price Agreement 433 for statewide electrical and gas welding services through April 2, 2031, on a pass/fail qualified vendor list with mini-bid pricing), and universities (Kennesaw State University, RFQ for metal fabrication and welding services task order across both campuses, proposals due October 29, 2026). Set-asides and preferences appear in approximately half of recent postings—SLBE bid discounts in Tampa and Austin, DVBE goals in California, and local business preferences in Texas and Georgia—signaling emerging small-business concentration in high-volume jurisdictions.
