UNSPSC 31331310: Titanium sonic welded structural assemblies

UNSPSC 31331310 Titanium sonic welded structural assemblies is a Commodity code that in recent state and local procurement activity frames bridge and building structural construction work — though the opportunities posted under this code do not involve titanium sonic welding specifically. Sarasota County solicited bids in July 2026 for a steel truss pedestrian bridge on Midnight Pass Road, and the City of San Antonio Capital Delivery Department issued two competitive sealed proposal requests in mid-2026 for the Hays Street Bridge Connections & Eastside Area Streets project and Fire Station #33 Facility Replacement, both funded through the 2022 Bond. These solicitations indicate that the code in practice captures general structural construction including steel and concrete assemblies, bridge decks, and building frames rather than the narrow titanium sonic-welded product category the code name suggests. Cities and counties appear to be the primary issuing bodies under this code.

Geographic activity centers on Texas and Florida based on recent postings. Sarasota County, Florida issued an IFB due July 27, 2026 for the Midnight Pass Road pedestrian bridge with steel truss deck and prestressed concrete piles. The City of San Antonio, Texas issued two RFCSPs: one due August 25, 2026 for bridge connections and eastside area streets improvements, with a pre-submittal conference on July 20, 2026, and another due July 30, 2026 for Fire Station #33 construction at 2935 Castroville Road, with a mandatory site visit on June 29, 2026 and pre-submittal conference on the same date. San Antonio's procurement contact for both projects was Jose Narvaez, Procurement Specialist III, with written questions submitted by July 28 and July 14, 2026 respectively, and submission through the CivCastUSA bidding portal.
