UNSPSC 31331513: Brass solvent welded structural assemblies

UNSPSC 31331513 Brass solvent welded structural assemblies is a Commodity code that in recent state and local solicitations appears to encompass structural steel and concrete components for bridge and infrastructure construction projects. The code shows limited direct activity under its nominal commodity definition; recent opportunities tagged to this code instead solicit full construction services for pedestrian bridges, roadway improvements, and facility replacement, where brass solvent welded assemblies would be minor or incidental materials within a larger structural scope. State and local issuing bodies using the code include city capital delivery departments (San Antonio) and county transportation authorities (Sarasota County), typically bundling structural materials procurement within competitive sealed proposals or invitations for bids for complete infrastructure projects rather than soliciting assemblies as discrete line items.

Recent opportunities cluster in Texas and Florida. Sarasota County, Florida posted an IFB in July 2026 for construction of a steel truss pedestrian bridge on Midnight Pass Road with a due date of July 27, 2026, scope including steel truss bridge deck, prestressed concrete piles, concrete end bents, and approach slabs. The City of San Antonio Capital Delivery Department posted two RFCsp (competitive sealed proposals) in June and July 2026: RFCSP2026025 for the Hays Street Bridge Connections and Eastside Area Streets project with proposals due August 25, 2026, and RFCSP2026071 for Fire Station #33 Facility Replacement with proposals due July 30, 2026 and a mandatory site visit on June 29, 2026. Both San Antonio projects are funded through the 2022 Bond program and include pre-submittal conferences and structured Q&A cycles. The code shows sporadic rather than sustained procurement activity.
