UNSPSC 73181905: Spot welding services

UNSPSC 73181905 Spot welding services is a Commodity code that encompasses repair, fabrication, and maintenance welding performed on-site or in vendor facilities across diverse state and local infrastructure, equipment, and construction projects. State and local governments procure under this code for mobile welding services on solid waste and water equipment, structural steel restoration on storage tanks and bridges, specialized welding in confined spaces such as water treatment facilities, track maintenance for transit systems, and general fabrication support for facility operations. Issuing bodies span city water departments, county solid waste management operations, transit authorities, state procurement offices, school districts, and universities. Welding services are often bundled with complementary work—plasma cutting, grinding, brazing, metal fabrication, and protective coating application—and typically structured as multi-year on-call or annual contracts with unit pricing, hourly labor rates, and material markups.

Recent activity is geographically distributed across Texas (Huntsville, Austin, Tampa), Florida (Hillsborough County, Tampa), California (Mt. San Antonio Community College District, Santa Clara County), Georgia (Kennesaw State University, Augusta, Statesboro, Greenville County in South Carolina), North Carolina (Charlotte Area Transit System), Rhode Island, and Oregon. Representative opportunities include the City of Huntsville, Texas ITB for restoration and pit welding of a half-million-gallon welded steel water storage tank (Bid NO. 27-05, due October 27, 2026) requiring approximately 250 pit welds deeper than 1/8 inch alongside structural repairs and coating; Mt. San Antonio Community College District RFQ for purchase and installation of forty-seven flexible vent extraction arms in its Welding Lab (due July 16, 2026, with 3% DVBE goal); Kennesaw State University task-order RFP for comprehensive metal fabrication and welding services supporting maintenance and renovation across both campuses (due October 29, 2026); and the State of Rhode Island Master Price Agreement (MPA 433) for statewide repair, maintenance, and fabrication welding on state equipment and facilities performed at multiple Rhode Island Department of Transportation service locations and other state agency sites (question period through March 1, 2031). Hillsborough County Board of County Commissioners posted two mobile welding ITBs for on-site repairs at solid waste facilities (estimated $207,429.10 over three years, with four-hour response times during business hours and 24-hour emergency completion windows). The Charlotte Area Transit System solicited proposals for Blue Line track welding services (Rebid #3, due August 20, 2026). Austin Water issued an IFB for plasma cutting and welding of stainless steel filter access plates requiring AWS D1.6 certification and confined-space entry program compliance (due May 21, 2026). Local preferences, prevailing wage compliance, and set-asides such as DVBE, SLBE, and small business discounts appear in multiple jurisdictions.
