UNSPSC 31331106: Non metallic bonded structural assemblies

UNSPSC 31331106 Non metallic bonded structural assemblies (Commodity) covers the supply and installation of prefabricated concrete and composite structural components used in bridge decks, building frames, and infrastructure projects. State and local governments solicit this code for pedestrian bridge construction, roadway structure replacement, and facility construction where precast concrete elements—such as prestressed piles, deck systems, and structural assemblies—form the primary load-bearing components. Issuing bodies include county transportation departments, municipal capital delivery offices, and city public works divisions. The code reflects work where structural design favors factory-fabricated, quality-controlled assemblies over site-cast concrete, particularly in bridge and critical infrastructure replacement projects.

Recent activity concentrates in Texas and Florida. Sarasota County (Florida) posted IFB 262861MN in July 2026 for construction of a steel truss pedestrian bridge on Midnight Pass Road with prestressed concrete piles and concrete end bents, due July 27, 2026. The City of San Antonio Capital Delivery Department posted two RFP opportunities in mid-2026: RFCSP2026025 for Hays Street Bridge Connections & Eastside Area Streets (proposals due August 25, 2026, with a pre-submittal conference on July 20, 2026), and RFCSP2026071 for Fire Station #33 Facility Replacement (proposals due July 30, 2026, with a mandatory site visit on June 29, 2026). Both San Antonio projects are funded through 2022 Bond programs and solicit competitive sealed proposals through the CivCastUSA portal. The issuing bodies represent a mix of county-level and municipal procurement offices, with San Antonio appearing as a repeat buyer in the recent pipeline.
