UNSPSC 31261700 Acoustical or noise control housings or enclosures is a Class code under which state and local governments procure replacement and installation of noise-abatement infrastructure, specifically fiberglass doors, frames, hardware, and deadbolt locks for highway sound barriers. The Maryland Department of Transportation State Highway Administration has posted multiple IFBs for replacement of noise abatement barrier doors and frames at various locations in Baltimore and Harford Counties, with work scopes limited to furnishing and installing fiberglass doors (4 feet by 7 feet), frames, appurtenances, and stainless steel deadbolt hardware across multiple sites. Issuing bodies under this code include state highway administration agencies responsible for maintaining noise barriers along transportation corridors.
