UNSPSC 31331313: Brass sonic welded structural assemblies

UNSPSC 31331313 Brass sonic welded structural assemblies, Commodity code, covers structural metal assemblies used in construction and infrastructure work, though recent state and local opportunities under this code show limited direct procurement activity aligned with the nominal scope. The three construction projects identified—Hays Street Bridge Connections & Eastside Area Streets (City of San Antonio), Midnight Pass Road Pedestrian Bridge (Sarasota County), and Fire Station #33 Facility Replacement (City of San Antonio)—involve structural steel, concrete, and general construction services rather than brass sonic welded assemblies specifically. The University of Wisconsin-Madison's general metals procurement (steel, aluminum, stainless steel) similarly does not reflect the code's specialized welding and brass-focused scope. Issuing bodies using this code range from municipal capital delivery departments to county public works and higher education institutions, though the frequency of recent activity under 31331313 appears low relative to the broader construction and materials procurement market.

Geographic activity is concentrated in Texas (San Antonio, Sarasota County in Florida) and Wisconsin, based on the available recent opportunities. The most recent solicitations include the City of San Antonio's Hays Street Bridge Connections RFP (response due August 25, 2026), Sarasota County's Midnight Pass Road Pedestrian Bridge IFB (response due July 20, 2026), and the City of San Antonio's Fire Station #33 Facility Replacement RFP (response due July 30, 2026). The code appears to see sparse use in recent state and local procurement relative to its nominal scope; bidders pursuing opportunities under 31331313 should verify alignment between the code classification and the actual materials and processes specified in solicitation documents, as tagging may not reflect the true scope of work.
