UNSPSC 81101533: Restoration architectural service

Architectural services for the design of restoration and conservation projects of old buildings.

UNSPSC 81101533 Restoration architectural service is a Commodity code that encompasses historic building exterior repairs, masonry stabilization, structural restoration, and environmental site remediation work where state and local governments are the primary buyers. Recent state and local solicitations under this code show a mix of historic preservation projects—including masonry repointing, facade restoration, and building envelope work—alongside mine closure and environmental reclamation initiatives funded by federal grants and state severance taxes. The Colorado Department of Natural Resources, Division of Reclamation, Mining and Safety emerges as a standout repeat buyer, issuing multiple documented quotations for mine safeguarding projects involving closure of shafts, adits, and subsidence features using polyurethane foam, corrugated steel pipe, steel grating, and native rock bulkheads. County, city, and special-purpose reclamation authorities also solicit under the code, including Marion County and Brevard County in Florida, Monroe County in Florida, Walworth County in Wisconsin, and the City of Sarasota, as well as historic restoration work through municipal cultural departments (City of Commerce, City of Plant City).

Geographic concentration is heaviest in Colorado, where mine closure projects span the western slope (San Juan County, Lake County, Chaffee County, Boulder County) and mountain front regions (Huerfano County). Historic restoration activity concentrates in Florida (Monroe, Marion, Brevard counties and Plant City) and isolated municipal projects in Georgia and Wisconsin. Representative recent solicitations include the Colorado Department of Natural Resources' PKAA Wandering Prospector Project (DQ1PKAA20260004762, documented quotations for 21 mine feature closures across Lake, Chaffee, and Pitkin counties, bid due July 2, 2026), the PKAA Tenderfoot Flat Top Project (DQ1PKAA20270000041, closure of 37 mine features with mandatory pre-bid meeting July 24, 2026, bid due August 12, 2026, 5% Service-Disabled Veteran-Owned Small Business preference), and Monroe County's East Martello Historic Masonry Restoration (RFP631, historic brick repair and repointing at Fort East Martello, proposals due June 4, 2026, three-year experience requirement and matching existing materials per Secretary of Interior Standards). Federal funding through the Department of Interior Office of Surface Mining Reclamation and Enforcement and compliance with Davis-Bacon prevailing wage, Build America Buy America Act, and Buy Clean Colorado Act requirements are standard conditions on Colorado PKAA projects; historic projects often require Secretary of Interior Standards compliance and local historic commission approval.
