UNSPSC 31331614: Jacket structure

A Jacket structure is a welded tubular space frame consisting of vertical or battered legs supported by a lateral bracing system. The function of the jacket is to support the topside facilities, provide supports for conductors, risers, and other appurtenances, and serve as a template for the foundation system.

UNSPSC 31331614 Jacket structure, a Commodity code, does not align with the state and local construction opportunities recently posted under this code. The recent solicitations capture bridge and building construction projects in which structural steel, concrete, and related materials figure as components, not as standalone jacket-structure procurements. The City of San Antonio Capital Delivery Department solicited proposals for the Hays Street Bridge Connections & Eastside Area Streets project (RFP RFCSP2026025, due August 25, 2026) and Fire Station #33 Facility Replacement (RFP RFCSP2026071, due July 30, 2026), while Sarasota County issued an invitation for bids on a steel truss pedestrian bridge with concrete and approach infrastructure (IFB 262861MN, due July 20, 2026). A University of Wisconsin–Madison materials procurement (RFB 2026-UWMSN-01207-RFB, due April 20, 2026) sought metals including steel and aluminum but does not specify jacket structures as a line item. The issuing bodies include city and county capital-delivery programs and a university procurement office, but no standout repeat buyers emerge from the set of opportunities tagged to this code.

Activity concentrates in Texas (San Antonio, Sarasota County in Florida) and Wisconsin, with no clear pattern of sustained demand for jacket-structure procurement in particular. The mismatch between the code's nominal scope and the actual work being solicited suggests that state and local agencies may tag bridge and building projects broadly without narrowing to specific structural components. Absent solicitations explicitly calling for jacket-structure design, fabrication, or installation as a prime deliverable, this code shows little relevant recent activity for vendors whose core competency is jacket structures.
