NIGP 15510: Buildings, Large, Prefabricated (Over 500 Sq.ft.)

NIGP 15510 Buildings, Large, Prefabricated (Over 500 Sq.ft.), an Item code, covers the purchase, furnishing, installation, and sometimes design-build delivery of prefabricated metal and modular buildings—structures over 500 square feet purchased or procured as turnkey or component-based systems rather than wholly custom construction. State and local governments soliciting under this code are acquiring metal carports, storage buildings, medical clinics, canopies, pole barns, recycling facilities, fire training structures, and modular classroom units, with vendors responsible for supplying structural components, doors, roofing, electrical and HVAC systems, site delivery, and often installation and permitting. Issuing bodies include county boards of commissioners, municipalities, state departments of transportation, school districts, utility authorities, and special-purpose entities such as the Kissimmee Utility Authority and Harris County Department of Education; Florida counties (Hillsborough, Pasco, Volusia, Clay, Walton) and Georgia municipalities and counties appear frequently as repeat buyers. Work being solicited ranges from small metal carports (Hillsborough County's July 2026 ITB for a metal carport) to large multi-building complexes, with recent representative opportunities including the Texas Department of Transportation's solicitation for pre-engineered fabric storage buildings (posted June 2026, Bonfire/Euna platform), Harris County Department of Education's competitive sealed proposal for modular buildings and related items maintenance through a Job Order Contracting IDIQ with a $200 million maximum aggregate across the cooperative (posted June 2026, components due June 16, 2026), and Walton County, Florida's ITB for a modular medical clinic measuring 3,100–3,500 square feet in Mossy Head (posted May 2026, bids due June 8, 2026).

Geographic activity concentrates in Florida, Georgia, Texas, and Oregon, with secondary activity in Minnesota (Sourcewell cooperative procurement for pre-engineered buildings and related services, posted March 2026, due May 19, 2026). Representative recent procurements show the diversity of jurisdictions and delivery methods: the City of Cumming, Georgia sought sealed proposals for design, engineering, fabrication, delivery, and erection of a pre-engineered metal building (posted May 2026, due June 4, 2026); White County, Georgia issued an RFP for a 35-by-100-by-16-foot steel frame storage building (posted April 2026, due May 28, 2026, with mandatory pre-proposal meeting May 8, 2026); Volusia County, Florida's IFB for a 4,720-square-foot fleet maintenance canopy at Tomoka Farms Landfill (posted April 2026, estimated construction cost $250,000); and Morgan County, Georgia's sealed design-build RFP for a 6,080-square-foot cardboard sorting facility (posted April 2026, due April 27, 2026, with mandatory pre-bid meeting April 7, 2026). Performance and payment bonds, prevailing wage compliance, and comprehensive insurance (general liability typically $1–3 million per occurrence) are standard requirements across recent solicitations. No specific set-asides for disadvantaged enterprises appear uniformly in the source material, though some solicitations (City of Fort Myers Fleet Maintenance Canopy RFP004324, Habersham County 2026-14 Metal Building) encourage MBE, FBE, and SBE participation.
