UNSPSC 31331311: Waspalloy sonic welded structural assemblies

UNSPSC 31331311 Waspalloy sonic welded structural assemblies is a Commodity code that in recent state and local procurement activity covers structural steel fabrication and welding for bridge and building construction projects. The three most recent opportunities posted under or near this code — a steel truss pedestrian bridge in Florida, a mixed-use greenway and street reconstruction project in Texas, and a fire station replacement in Texas — show the code capturing work that involves structural steel components, welded connections, concrete structural elements, and site work rather than waspalloy-specific assemblies as the abstract code name suggests. The issuing bodies are municipal and county governments pursuing capital projects funded through bonds and general operations. Sarasota County in Florida and the City of San Antonio in Texas appear as solicitors, indicating that county transportation departments and city capital delivery offices use this code for competitive sealed proposal and invitation-for-bid construction solicitations.

The recent activity concentrates in Florida and Texas, with no opportunities identified outside these two states in the source material. Sarasota County posted IFB 262861MN for the Midnight Pass Road Pedestrian Bridge with a due date of July 20, 2026, covering steel truss decking, prestressed concrete piles, concrete end bents, and approach slabs. The City of San Antonio Capital Delivery Department issued RFP RFCSP2026025 for Hays Street Bridge Connections & Eastside Area Streets with a proposal due date of August 25, 2026 at 2:00 p.m. Central Time, including a pre-submittal conference on July 20, 2026; the scope encompasses greenway construction, concrete beams, structural shapes, and roadway improvements. The same city issued RFP RFCSP2026071 for Fire Station #33 Facility Replacement with proposals due July 30, 2026 at 2:00 p.m. Central Time and a mandatory site visit on June 29, 2026, covering structural construction across site work, concrete, structural steel, HVAC, electrical, and building systems. Written questions on the San Antonio solicitations close July 28, 2026 and July 14, 2026 respectively.
