NIGP 91076: Welding Maintenance and Repair Services (incl. Brazing, Casting, and Soldering)

NIGP 91076 Welding Maintenance and Repair Services (including Brazing, Casting, and Soldering), an Item code, covers on-call and as-needed welding, fabrication, and metal repair work across water utilities, transit systems, school districts, cities, and counties. State and local governments procure portable and shop welding services for infrastructure maintenance—water vault repairs, equipment fabrication, rail track welding, bridge railing installation, tank structural repairs, and emergency mobile welding—typically performed by certified welders holding AWS or AISC credentials and managing response times from same-day to 72-hour mobilization depending on urgency. Issuing bodies span utilities (Alameda County Water District, Austin Water, City of Tampa Water Department, North Texas Municipal Water District), transit authorities (Charlotte Area Transit System), school districts (Austin Independent School District, Mt. San Antonio Community College District, Northside Independent School District), counties (Greenville County, Hillsborough County, DeKalb County, Santa Clara County), and cities (Atlanta, Austin, New Smyrna Beach, Statesboro). Water systems and transit authorities appear as repeat buyers for track and pipeline maintenance, while school districts solicit for facility repairs and equipment installation.

Recent opportunities cluster in the Southeast and Southwest. The Charlotte Area Transit System posted two separate rebids for Blue Line track welding services (due March 6 and August 20, 2026); Greenville County issued an RFP for fabrication and installation of 244 linear feet of weathering-steel bridge railings on the Swamp Rabbit Trail due August 5, 2026, requiring AWS D1.1-certified welders; and the City of Tampa issued an ITB for as-needed welding and fabrication services on water vaults with an estimated value of $70,000 and a 5% bid discount for certified Small Local Business Enterprises, due July 31, 2026. The Alameda County Water District solicited on-call field and shop welding services (anticipated 1,500 field hours and 500 shop hours annually) with bids due May 1, 2026. Hillsborough County issued an ITB for mobile welding services across four solid waste facilities with an estimated project value of $207,429.10 through July 31, 2028, due June 29, 2026.

New Smyrna Beach Utilities (Florida) posted an ITB for steel repair and protective coating work on a corroded water treatment plant walkway with performance in 30 days, due May 12, 2026. Geographic activity is concentrated in California (Santa Clara County JOC, Alameda County Water District, City of Austin, Mt. San Antonio College), Florida (Tampa, Hillsborough County, New Smyrna Beach), Georgia (Atlanta, Charlotte CATS, DeKalb County, Greenville County, Statesboro), and Texas, with additional activity in North Carolina, Massachusetts, and South Carolina. Set-asides and preferences are present in some procurements—Tampa designated SLBEs for bid discount consideration; Austin Water applied Local Business and Small Business preferences; and Atlanta BeltLine established a 30% DBE goal for capital repair services. Most solicitations require AWS, AISC, or ASME certifications, commercial general liability insurance in the $1 million to $2 million range, performance and payment bonds, and prevailing wage compliance in California and selected other jurisdictions.
