UNSPSC 40141900: Ducts

A duct is a tube or channel through which fluids or gases may be moved.

UNSPSC 40141900 Ducts is a Class code encompassing air duct accessories, dampers, and related components installed in building systems, typically as part of HVAC, building automation, and fire/smoke control retrofits. State and local governments procure ducts and duct accessories primarily through capital construction and facility upgrade projects, often bundled with broader mechanical system work rather than as standalone commodity purchases. Recent solicitations show county facilities (corrections centers, operations centers) and municipalities (transit authorities, water utilities) as primary buyers, with work ranging from smoke control system retrofits to fuel storage facility upgrades. The code captures both the physical duct materials and the accessory hardware—dampers, terminal boxes, duct heaters, and energy recovery components—that integrate into modern building systems.

Orange County, Florida issued the most recent active opportunity under this code: Solicitation Y26-718 (Corrections Booking and Release Center, Building Automation System, Smoke and Fire Alarm Air Duct Accessories), an IFB with bids due October 20, 2026, valued at $2.89 million. The scope encompasses retrofitting fire/smoke dampers, terminal boxes, duct heaters, air handling units, and energy recovery units as part of a Johnson Controls Metasys controls installation; work includes separation of smoke control from non-smoke control systems and replacement of associated ceiling infrastructure. Service Disabled Veteran-owned businesses receive a 5% bid preference. A non-mandatory pre-bid meeting with site visit occurred September 1, 2026; questions closed September 10, 2026. Secondary opportunities posted earlier show related but distinct scopes: the City of Leesburg, Florida (IFB 26-015-LK, June 18, 2026 due date) procured water main replacement with associated piping, and the City of Charlotte (RFP 26920271769, October 15, 2026 due date) sought boiler and chiller maintenance services. Most recent activity concentrates in Florida, with scattered opportunities in Washington state and Minnesota through cooperative purchasing vehicles. The code shows moderate seasonal activity tied to municipal capital improvement cycles and facility renovation programs.
