UNSPSC 31331612: Copper welded or brazed structural assemblies

UNSPSC 31331612 Copper welded or brazed structural assemblies (Commodity) appears in recent state and local solicitations primarily as an incidental specification within larger construction projects rather than as a standalone procurement driver. The three construction opportunities posted in the source — two infrastructure projects from San Antonio's Capital Delivery Department and one pedestrian bridge from Sarasota County — reference structural materials and assemblies generically within their scopes (structural shapes, concrete beams, steel truss components) without singling out copper welding or brazing as a discrete deliverable. A fourth opportunity from the University of Wisconsin-Madison for metals procurement (steel, aluminum, stainless steel) does not address copper work. State and local buyers appear to bundle copper welded or brazed assemblies as subordinate line items within general construction contracts rather than as standalone goods purchases.

Recent activity concentrates in Texas and Florida, with the City of San Antonio Capital Delivery Department appearing twice as an issuing body. The San Antonio Hays Street Bridge Connections & Eastside Area Streets project (RFCSP 26-025) is requesting competitive sealed proposals due August 25, 2026, covering linear greenway and roadway improvements with a mandatory pre-submittal conference on July 20, 2026. Sarasota County solicited construction bids under IFB format for the Midnight Pass Road Pedestrian Bridge, with bids due July 20, 2026, specifying steel truss components, prestressed concrete piles, and concrete work. The San Antonio Fire Station #33 Facility Replacement (RFCSP 26-071) is requesting competitive sealed proposals due July 30, 2026 with a mandatory site visit on June 29, 2026. These opportunities reflect general construction procurement where copper welded or brazed structural assemblies, if specified, would be embedded in the broader material and labor scope.
