UNSPSC 81102902: Cultural heritage property design service

Design engineering and supervision services for the conservation-restoration of cultural heritage property. Includes design work as well as documentation.

UNSPSC 81102902 Cultural heritage property design service is a Commodity code covering mine closure and reclamation design and construction services procured by state environmental and natural resource agencies, county departments, and municipal governments. State and local buyers are engaging contractors to close abandoned mine features—primarily adits, shafts, and subsidence features—through specialized design and installation of polyurethane foam plugs, steel grating, bat-access closures, corrugated steel pipe systems, concrete monolithic plugs, and native rock bulkheads, often with revegetation and sediment control components. The issuing bodies are predominantly state departments of natural resources and divisions of reclamation, mining, and safety (particularly Colorado's Public Lands and Acquisition Authority), alongside county governments in Colorado, Florida, and Georgia. Colorado dominates recent activity, with the Division of Reclamation, Mining and Safety posting multiple solicitations for mine closure across Lake, Chaffee, Pitkin, Boulder, Gunnison, Clear Creek, Huerfano, San Juan, and Custer counties; federal funding through the Department of the Interior Office of Surface Mining Reclamation and Enforcement and U.S. Forest Service, combined with state Severance Tax revenue, drives most of these projects.

Representative recent opportunities include the Colorado Department of Natural Resources' DRUM Tenderfoot Flat Top Project (DQ1PKAA20270000041, RFQ, bids due August 12, 2026) for closure of 37 mine features in Mesa County with Davis-Bacon prevailing wages and a 5% Service-Disabled Veteran-Owned Small Business preference; the Gold Creek Project (DQ1PKAA20260005321, RFQ, bids due August 4, 2026) covering 14 mine features in Gunnison County; and the Cottonwood Mine Closure Project (DQ1PKAA20260005331, RFQ, bids due August 20, 2026) spanning Clear Creek and Gilpin counties with mandatory virtual pre-bid meetings and federal/state funding. A distinct outlier is Orange County, Florida's emergency bridge replacement (Y26742, sealed bids, bids due July 7, 2026) at $6.2 million estimated cost, which appears misclassified under this code. Activity is concentrated in Colorado with secondary sporadic municipal and county activity in Florida and Georgia on unrelated restoration work; the code shows little activity outside Colorado's legacy mine reclamation programs.
