UNSPSC 31261700: Acoustical or noise control housings or enclosures

UNSPSC 31261700 Acoustical or noise control housings or enclosures is a Class code under which state and local governments procure noise barrier door systems, frames, hardware, and installation services for infrastructure sound mitigation. The scope encompasses furnishing and installing fiberglass or comparable doors with frames, deadbolt locks, stainless steel hardware, and related appurtenances at roadway noise barriers and similar facilities, including removal of existing systems and restoration of affected areas. State transportation departments and county transportation or public works offices are the primary issuing bodies under this code. Work solicited includes both component replacements (deadbolts, hardware) and full door-and-frame system replacements at multiple site locations, with bidders typically required to demonstrate a minimum of two years' experience in related construction or noise abatement work, maintain specified general liability and workers' compensation insurance, and comply with applicable state standard specifications and building codes.

The Maryland State Highway Administration has posted multiple solicitations under this code in 2026, reflecting sustained activity in the Baltimore and Harford Counties region. The Maryland SHA District 4 Office issued IFB 509D41428A, posted June 10, 2026, with bids due June 30, 2026, seeking replacement of noise abatement barrier doors, frames, and hardware across two line items (eight deadbolt replacements and four complete door and frame replacements); the contract term runs August 1, 2026 through June 30, 2028 as a fixed-price, single-award contract with no set-asides established. A companion solicitation, 509D41428SB, was posted April 14, 2026 by Baltimore County with bids due April 28, 2026, also targeting replacement of noise abatement doors and frames at various locations in Baltimore and Harford Counties. These solicitations indicate active, recurring procurement of noise barrier maintenance and replacement work in Maryland's transportation infrastructure, with response windows typically fourteen to twenty days and no federal funding or preferences applied.
