NIGP 91485: Welding

NIGP 91485 Welding, an Item code, encompasses portable and shop welding services for state and local infrastructure maintenance and capital projects — principally steel fabrication, repairs, and on-site mobile welding for water systems, mechanical equipment, and facility upgrades. State and local governments buy these services on as-needed and term-contract bases from community colleges, state departments, municipal utilities, county medical centers, and corrections facilities. Issuing bodies span Washington state community colleges (Highline, South Seattle, Everett, Big Bend, Lake Washington Institute of Technology, Clover Park, North Seattle, Shoreline, Tacoma, Pierce, and Clark), Washington state agencies (Department of Corrections, Department of Social & Health Services, Department of Children Youth and Families, Department of Veterans Affairs, Department of Ecology), the City of Tampa Water Department, City of Tucson, Maryland Department of Transportation, City of Lubbock, Georgia's Technical College System, Santa Clara County (California), and Augusta, Georgia. Recent procurement activity reflects both emergency repairs and planned capital work: Mt. San Antonio Community College District's welding lab vent extraction arm installation and purchase (IFB, July 2026, $150,000 base estimate, mandatory job walk June 9, 3% DVBE goal); Maryland Department of Transportation's mobile welding services at Centreville and Stevensville shops (IFB, SBE-reserved, September 2026, 24-hour response requirement); City of Tampa Water Department welding and fabrication for water vaults (ITB, SLBE 5% discount capped at $10,000, July 2026, $70,000 estimated value); City of Lubbock water utility welding and machinist services (RFP, August 2026, 70% price weighting, automatic renewal); and Augusta, Georgia welding and fabrication at Deans Bridge Environmental Services Facility (ITB, annual contract, September 2026, Local Bidders Preference where applicable).

Activity concentrates in Washington state — particularly its community college system and state corrections and health agencies — and California, with scattered solicitations in Florida, Texas, Georgia, Maryland, and Arizona. Recent activity shows term contracting (one-year initial periods with renewal options ranging from three to four one-year extensions) as the dominant structure, with pricing remaining firm for the initial 12-month period and escalation thereafter capped by CPI or mutual agreement. Bonding and insurance thresholds are standard: Commercial General Liability of $1 million per occurrence minimum, Workers' Compensation as required by state law, and performance and payment bonds typically at 100% of contract price for projects over defined thresholds. Prevailing wage requirements apply in California public works and Davis-Bacon work in federally funded water projects. Set-asides and preferences include SBE reservations (Maryland), SLBE bid discounts (Tampa), DVBE participation goals (Mt. San Antonio, 3%), and Local Bidders Preferences (Tampa, Augusta, Lubbock). Washington state procurement appears to use streamlined IFB posting with minimal scope detail in the notices themselves, requiring vendors to request full bid documents; California County of Santa Clara is conducting heavy seismic compliance work at healthcare facilities with mandatory prequalification rounds preceding formal RFP issuance.
