NIGP 15518: Cabins, Storage Buildings, etc. (Pre-Engineered in Kits, Ready to Assemble and Erect)

NIGP 15518 Cabins, Storage Buildings, Etc. (Pre-Engineered In Kits, Ready To Assemble And Erect), an Item code, encompasses the procurement of pre-engineered metal and steel structures — primarily single-story storage buildings, equipment shelters, pole barns, and modular housing units — that arrive as kits or are factory-built for on-site assembly and completion by state and local governments. Recent solicitations show counties, municipalities, and special-purpose districts buying turnkey or design-build metal structures for fleet maintenance facilities, wastewater treatment plants, first aid stations, cardboard sorting facilities, and hazardous materials storage, with scopes typically including site prep, utility integration, permitting, and performance/payment bonds.

Activity under the code spans Florida, Georgia, and Minnesota cooperative purchasing vehicles, with counties (Volusia, Pasco, Clay, Okaloosa, Collier, Habersham, Morgan, Macon-Bibb) and municipal governments (Sarasota, Swainsboro, DeBary, Jacksonville Transportation Authority) as primary issuing bodies. Representative recent opportunities include Volusia County's IFB for a 4,720-square-foot pre-engineered metal building canopy at Tomoka Farms Landfill (Solicitation 25B155LL, $250,000 estimated value, response due November 2025); Pasco County's IFB for a 54-foot gable pole barn at the Shady Hills Wastewater Treatment Plant (IFBSV26056, due April 7, 2026); Morgan County's design-build RFP for a 6,080-square-foot cardboard sorting facility (PE77426, due April 27, 2026); and Macon-Bibb County's RFQ for modular housing developers serving affordable housing (27-001-LH, funded by $7.5 million from the American Rescue Plan Act, due August 6, 2026). Sourcewell cooperative purchasing issued two separate solicitations (26RFP060926 for modular buildings and portable storage due June 9, 2026; 26RFP051926 for pre-engineered buildings due May 19, 2026), signaling ongoing demand across its multi-state participating entities. Local vendor preferences appear in Macon-Bibb County (5 percent within lowest responsive bid) and Pasco County (Pasco and adjacent counties). Mandatory pre-bid meetings, site visits, and stringent bonding requirements (performance and payment bonds equal to 100 percent of award value) are standard. Most procurements favor lowest responsive and responsible bidders and do not restrict participation by enterprise category.
