UNSPSC 31331306: Non metallic sonic welded structural assemblies

UNSPSC 31331306 Non metallic sonic welded structural assemblies is a Commodity code. Recent state and local opportunities tag this code to structural construction work — specifically steel truss bridges, prestressed concrete piling systems, and concrete structural elements integrated into larger building and infrastructure projects. The work being solicited is primarily general construction contracting that incorporates prefabricated or site-assembled structural components as part of the broader scope. Issuing bodies include county transportation authorities and municipal capital delivery departments, with San Antonio's Capital Delivery Department appearing as a repeat buyer across multiple 2022 Bond-funded construction projects. The geographic spread of recent activity centers on Texas, with additional activity in Florida.

Representative opportunities include Sarasota County's IFB for a steel truss pedestrian bridge on Midnight Pass Road, with bids due July 27, 2026, encompassing steel deck, prestressed concrete piles, concrete end bents, approach slabs, and sidewalks; and the City of San Antonio Capital Delivery Department's RFP for the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025), with proposals due August 25, 2026, covering a linear creek greenway extension and roadway improvements funded through the 2022 Bond. San Antonio also posted RFCSP2026071 for Fire Station #33 Facility Replacement, an RFP with proposals due July 30, 2026, involving new-station construction that includes structural shapes and site-work elements. The tagging of this Commodity code to general construction RFPs and IFBs suggests the code captures structural assembly work as one component within larger building and civil infrastructure contracts rather than as standalone procurement lines.
