UNSPSC 31331601: Aluminum welded or brazed structural assemblies

UNSPSC 31331601 Aluminum welded or brazed structural assemblies is a Commodity code that in recent state and local procurement activity encompasses structural steel components and bridge deck systems for transportation infrastructure projects. The solicitations currently posted under this code describe work that diverges from the narrow "aluminum welded or brazed" scope — they are soliciting construction of steel truss pedestrian bridges, bridge connections, and structural components for fire station facilities, all requiring steel structural shapes, decks, and assemblies rather than aluminum-specific work. State and local governments issuing under this code include counties and cities procuring capital construction projects, with Sarasota County and the City of San Antonio both soliciting major infrastructure work in the most recent cycle. The work is being solicited through competitive sealed proposals (RFP format) and invitations for bids (IFB format), with construction contracts awarded for the full project duration.

Recent opportunities are concentrated in Florida and Texas. Sarasota County solicited an IFB for construction of a steel truss pedestrian bridge on Midnight Pass Road with a due date of July 27, 2026, including deck, piles, end bents, and approach slabs. The City of San Antonio Capital Delivery Department has posted two major RFPs: the Hays Street Bridge Connections & Eastside Area Streets project (RFCSP2026025) due August 25, 2026, encompassing bridge connections and linear greenway infrastructure across multiple streets, and Fire Station #33 Facility Replacement (RFCSP2026071) due July 30, 2026, involving construction of a new fire station with structural components. Both San Antonio projects include mandatory pre-submittal conferences and site visits and are funded through the 2022 Bond program.
