UNSPSC 31351300: Riveted tube assemblies

UNSPSC 31351300 Riveted tube assemblies (Class) shows little relevant recent state and local procurement activity, with the single posted opportunity in the dataset reflecting a significant scope mismatch. The City of Tucson RFP 240080 for steel fabrication services, posted March 26, 2026 with response due November 30, 2023, solicits broad metal fabrication work—custom doors, steel cages, anti-vandalism boxes, handrails, and protective infrastructure for city assets—rather than the specialized riveted tube assemblies the code nominally describes. The work encompasses metal fabrication, machining, metal finishing, mobile welding, and emergency welding across steel, galvanized steel, stainless steel, aluminum, and coated materials, performed primarily at the vendor's own shop with a typical six-week completion timeline and one-year initial term with four optional one-year extensions.

The Tucson opportunity carries federal compliance requirements including HUD Section 3 Program mandates (25% of labor hours by Section 3 Workers, 5% by Targeted Section 3 Workers), DBE participation, Buy America provisions, and civil rights standards. A pre-submittal virtual meeting was held November 16, 2023, with evaluation focused on method of approach, qualifications, experience, and pricing. The code itself does not appear to be actively tracked under its narrow riveted tube assembly definition in current state and local procurement; absent further opportunities aligned with that specific product line, vendors should verify whether opportunities posted under this code represent actual tube assembly work or reflect broad-scope steel fabrication solicitations that may be miscoded.
