UNSPSC 30171608: Tilt or transom windows

UNSPSC 30171608 Tilt or transom windows (Commodity) encompasses the supply and installation of specialized window systems for state and local facilities, though recent opportunities show the code is being applied more broadly to storefront glazing, commercial window replacement, and building envelope renovation work. State and local buyers under this code include county governments, municipal authorities, and utility districts sourcing windows for public buildings, courthouses, government offices, and utility infrastructure. The work is predominantly installation-focused, combining material procurement with labor-intensive on-site setup, framing adjustments, sealing, and weatherproofing. Recent solicitations call for energy-efficient glazing (low-E glass, dual-pane tempered units), impact-resistant systems where required by local building codes, aluminum storefront assemblies, hardware installation, and comprehensive warranties spanning one to ten years depending on the scope. Contractors routinely encounter Florida Building Code compliance requirements, OSHA mandates, permit acquisition, and insurance thresholds (typically $1 million general liability minimum). A 25 percent county business enterprise goal applies to at least one open-end indefinite-quantity contract; local-business location preferences and prevailing-wage determinations surface in some jurisdictions.

Recent activity clusters in Florida, with five of seven live opportunities posted between August and October 2026 across Kissimmee Utility Authority (RFQ for twelve sliding windows at a substation pavilion, July 29, 2016 due date), Escambia County (ITB for east-facing storefront panels at two downtown Pensacola historic buildings, October 14, 2026 due date), Monroe County (RFQ for commercial aluminum storefront and entrance doors at the Old Plantation Key Courthouse, September 28, 2026 due date), Broward County (open-end IFQ for windows, glass doors, and related repairs across multiple agencies with a 25 percent CBE goal, October 2, 2026 due date), and Orange County (sealed bid for aluminum storefront window replacement at the Fredrick Douglas Building, estimated cost $319,428.00, August 13, 2026 due date). The City of Tucson issued an annual requirements contract for window glass and installation services (RFP 226043, August 18, 2022 due date) covering commercial, industrial, and residential properties. A single opportunity in Portage County, Wisconsin addresses aluminum entrances and storefronts as one of four trade packages in a courthouse remodel (June 2, 2026 due date). Florida dominates the recent pipeline; Arizona and Wisconsin represent the geographic tail.
