UNSPSC 73181906: Projection welding services

UNSPSC 73181906 Projection welding services (Commodity) covers specialized welding work—particularly repair, fabrication, and restoration of welded structures and equipment—that state and local governments are actively procuring across water infrastructure, solid waste operations, transit systems, and facilities maintenance. Recent solicitations show demand for on-site mobile welding for equipment repairs, structural restoration of large storage tanks, track maintenance for transit systems, and specialized work on confined-space or stainless-steel applications. The issuing bodies span water utilities, county solid waste departments, transit authorities, community colleges, state procurement offices establishing master agreements, and municipal facilities departments. Welding services are often bundled with related metal fabrication, cutting, and equipment repair; many jurisdictions structure these as on-call or task-order contracts with hourly labor rates and unit pricing rather than fixed-price projects.

Activity is geographically distributed across the Southeast, Southwest, and Mid-Atlantic, with recent solicitations posted from Texas (Huntsville, Austin, Tampa), Florida (Hillsborough County, Tampa), Georgia (Kennesaw State University, Augusta, DeKalb County, Statesboro), South Carolina (Greenville County), California (Mt. San Antonio Community College District, Santa Clara County), Rhode Island, North Carolina (Charlotte transit), and Oregon. Representative opportunities include Hillsborough County's mobile welding and fabrication services for solid waste equipment (ITB-26-00389, estimated $207,429.10 over three years, responses due September 16, 2026), the City of Huntsville's half-million-gallon water storage tank restoration including pit welds and coating (Bid 27-05, due October 27, 2026 with mandatory site visit October 15), the State of Rhode Island's master price agreement for on-site and facility-based welding services statewide (MPA 433, Pass/Fail qualification model with mini-bid quotations), Kennesaw State University's open task-order solicitation for metal fabrication and welding across both campuses (responses due October 29, 2026), and the City of Austin's plasma cutting and stainless-steel welding contract for water treatment filter access plates (IFB 2200 BYS1055, requiring AWS D1.6 certification and confined-space compliance, due May 21, 2026 at 2:00 p.m. CT). Prevailing wage requirements, bonding, commercial general liability insurance ($1 million typical), and specific welding certifications (AWS D1.1, AWS D1.6, TIG/MIG/arc methodologies) are standard compliance expectations across recent awards.
