NIGP 28522: Conduit and Fittings, Rubber

NIGP 28522 Conduit and Fittings, Rubber (Item) covers the supply and installation of rubber and non-metallic conduit systems used by state and local water utilities, transit authorities, and municipalities for underground infrastructure work. State and local governments procure these materials—primarily HDPE and PVC conduit in sizes ranging from 2 inches to 8 inches—as part of broader utility system upgrades, water treatment facility improvements, and site infrastructure projects. The code encompasses both material supply and full installation services, including excavation, traffic control, trenching, riser installation, and as-built certification. Recent solicitations show water utilities and municipal governments dominating activity, with equipment and service bundles commonly packaged together in fixed-price or cost-plus arrangements over multi-year terms.
