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

NIGP 15510 Buildings, Large, Prefabricated (Over 500 Sq.ft.), Item code, encompasses the procurement of standalone, factory-manufactured or pre-engineered structures exceeding 500 square feet—primarily metal buildings, modular facilities, and fabric structures—that state and local governments deploy for storage, operations, administration, and specialized use. Recent solicitations show jurisdictions purchasing complete turnkey solutions: pre-engineered metal warehouses with structural framing, roofing, and doors; modular medical clinics and administrative buildings delivered and installed on-site; metal carports for equipment protection; and pavilion structures with integrated utilities and site improvements. The issuing-body mix spans city procurement offices (DeBary, Tampa, San Antonio, Cumming, Florida), county governments and school districts (Marion County, Muskegon Public Schools, Harris County Department of Education, Walton County, White County), and state transportation departments (TxDOT, Texas Department of Transportation). Repeat buyers include TxDOT (which has posted at least three solicitations under this code in 2026) and several Florida municipalities seeking modular and metal structures for public facilities and temporary storage.

Recent opportunities cluster in Florida, Texas, Georgia, and Michigan. Representative solicitations include the City of DeBary's ITB for a 7,962-square-foot fire station (sealed bids due March 30, 2016, $1,750,000 estimated cost), the City of Tampa's RFQ for an enclosed 22-by-26-foot metal carport (quotes due October 16, 2026), Muskegon Public Schools' RFP for a pre-engineered metal administrative building at 1826 Hoyt Street with a mandatory pre-bid conference (proposals due September 24, 2026), Marion County Procurement's solicitation for a pre-engineered metal storage building and office renovation (subcontractor bids due August 20, 2026), the City of San Antonio's RFP for Main Plaza Renovations featuring a 5,500-square-foot pavilion shade structure and site improvements (proposals due December 1, 2026), TxDOT's IFB for a 32-by-42-foot pre-engineered fabric building with HUB subcontracting-plan requirements (bids due August 10, 2026), Walton County's ITB for a modular medical clinic approximately 3,100 to 3,500 square feet (bids due June 8, 2026), and White County's RFP for a 35-by-100-by-16-foot steel storage building with six roll-up doors (proposals due May 28, 2026). Bond and insurance requirements are standard across opportunities. TxDOT procurements often carry mandatory HUB or VetHUB subcontracting-plan compliance. Most jurisdictions reserve the right to award by aggregate, line item, or division and to reject any or all bids.
