UNSPSC 40141902: Rigid ducts

UNSPSC 40141902 Rigid ducts, a Commodity code, covers the supply and installation of rigid ducting systems used in building mechanical, smoke control, and fire suppression applications. State and local governments procure rigid ducts primarily as components of larger building systems projects — replacement of building automation systems, installation of smoke control and fire alarm air handling systems, retrofitting of existing HVAC infrastructure, and associated ductwork fabrication and installation. The work typically involves coordination with building controls vendors, fire protection systems integrators, and mechanical contractors. Issuing bodies include county facilities departments managing detention and correction centers, municipal utilities managing water infrastructure, and transit authorities managing regional transportation facilities.

Recent activity centers in Florida, where Orange County is soliciting sealed bids for rigid duct accessories as part of a $2.89 million Corrections Booking and Release Center building automation system and smoke/fire alarm retrofit (IFB Y26-718, response due October 20, 2026).

Orange County's Y26-718 opportunity explicitly requires fire/smoke dampers, terminal boxes, duct heaters, air handling units, and energy recovery units; the contractor must obtain preconstruction approvals, field-verify existing conditions, and manage temporary heating and cooling during construction.

Bid bonds of 10 percent of estimated contract value and performance bonds equal to contract amount are standard. Electronic submission through OpenGov e-Procurement Platform is mandatory for Orange County; hand delivery, mail, fax, and email are rejected.
