UNSPSC 81102901: Cultural heritage property maintenance engineering service

Maintenance engineering and supervision services for the conservation-restoration of cultural heritage property. Includes inspection, servicing and repair work as well as documentation.

UNSPSC 81102901 Cultural heritage property maintenance engineering service is a Commodity code capturing mine closure, mine remediation, and historic structure restoration services that state and local governments buy to address environmental liabilities and preserve heritage assets. Colorado's Division of Reclamation, Mining and Safety dominates recent activity, soliciting multiple mine closure projects through the Public Lands and Acquisition Authority (PKAA) framework, with Monroe County, Florida and several municipal and county governments across the South and Mountain West also engaging in similar work. The specific scope includes polyurethane foam mine plugs, corrugated steel pipe closures with bat accommodations, steel grating installations, backfill operations, sediment control, site revegetation, historic masonry repointing and restoration, and related safety and environmental action planning. Winning bidders must typically hold Davis-Bacon prevailing wage compliance, comprehensive mine safety certifications (MSHA for underground work), White-Nose Syndrome decontamination protocols, and Build America Buy America Act compliance; many solicitations require performance and labor-material bonds at 100 percent of contract value and 5 percent service-disabled veteran-owned small business bid preferences.

Representative recent activity is concentrated in Colorado's mountain counties and Florida. Colorado Department of Natural Resources issued multiple documented quotations between April and July 2026 for projects including the Wandering Prospector Project (Lake, Chaffee, and Pitkin counties; bids due July 2, 2026), the Madonna Project (Chaffee County; bids due June 24, 2026), the DRUM Tenderfoot Flat Top Project near Gateway on BLM land (bids due August 12, 2026), and the Walsen Project (Huerfano County; bids due June 24, 2026)—each covering ten to twenty-plus mine features with lump-sum mobilization, safety planning, and installation pricing. Monroe County, Florida issued an RFP for East Martello Historic Masonry Restoration at Fort East Martello Tower (proposals due June 4, 2026) requiring historic lime-mortar repointing and brick replacement under Secretary of Interior Standards. The code also captures occasional municipal heritage work such as the City of Commerce, Georgia's cultural center renovation (RFP 26-014; due May 28, 2026) and specialized projects like the Georgia World Congress Center Authority's Olympic Cauldron relocation and installation at Centennial Olympic Park (proposals due July 13, 2026). Liquidated damages are uniformly set at $400 per day for mining projects and scaled by contract value for historic work; construction windows typically run 40 to 60 calendar days for mine closure and 240 days or longer for building restoration. Activity is strongest in Colorado, Florida, Georgia, and the upper South; set-asides favor service-disabled veteran-owned businesses across all recent Colorado procurements.
