NIGP 28518: Conduit and Fittings, Cast Iron and Malleable Iron

NIGP 28518 Conduit And Fittings, Cast Iron And Malleable Iron, an Item code, covers the furnishing and installation of conduit systems and related materials for utility infrastructure, water delivery, and electrical work. State and local governments procure this code primarily through construction and infrastructure contracts that bundle conduit supply with installation labor, trenching, pavement work, and ancillary services. Issuing bodies span utility authorities, county governments, school districts, and other public agencies. The Kissimmee Utility Authority and Collier County, Florida are recent active buyers; KUA's continuing conduit installation RFP (RFP26036JG, due July 28, 2026) specified HDPE conduit in sizes 2" through 8", Schedule 40 gray restrained joint conduit, and inner duct placement across multiple concurrent job sites, while Collier County's NEUF Perimeter Fence, Irrigation, and Landscaping IFB (due October 8, 2026, $3.4 million) included 26,000 linear feet of PVC-80 2-inch conduit as part of a larger irrigation and site work package. These recent procurements show that conduit codes bundle material supply, labor, and related construction services in firm fixed-price or cost-plus arrangements with multi-year terms and optional renewals.

Recent activity concentrates in Florida, with secondary representation from Texas school districts and cooperative purchasing vehicles serving multi-state jurisdictions. Northside Independent School District in San Antonio posted an IFB for electrical equipment, parts, supplies, and services (IFB2026098, due July 1, 2026) that may include conduit-related materials, though the posting does not itemize scope. Sourcewell, a State of Minnesota cooperative, issued RFP 061626 for law enforcement equipment with a due date of June 16, 2026, serving multiple Washington counties and public entities across the United States and Canada, though conduit is tangential to that solicitation's primary focus. Geographic spread remains heavily weighted toward Florida utilities and county infrastructure procurement, with sporadic activity in school districts and cooperative purchasing arrangements serving broader regional and national constituencies.
