UNSPSC 81102900 Cultural conservation-restoration engineering services is a Class code covering mine closure, hazardous site remediation, and historic building restoration work that state and local governments buy to address legacy mining hazards, environmental compliance, and preservation of cultural landmarks. The code shows substantial recent activity concentrated in Colorado, where the state Department of Natural Resources Division of Reclamation, Mining and Safety has posted dozens of solicitations for mine closure projects funded by the U.S. Department of Interior Office of Surface Mining Reclamation and Enforcement and Colorado Severance Tax revenues; secondary activity appears in Florida counties (Marion, Brevard, Monroe, Collier) posting shoreline restoration, bridge repair, and building preservation work, plus isolated projects in Georgia, South Carolina, Kansas, Wisconsin, and Texas. The Colorado mine-closure work dominates the recent stream, encompassing polyurethane foam plugs, steel grates with bat-protective features, corrugated steel pipe installations, backfill operations, and revegetation across dozens of adits and shafts at elevations between 7,000 and 9,000 feet on Bureau of Land Management and U.S. Forest Service land; work locations span high mountain terrain with access varying from vehicle to foot-only and helicopter-recommended sites, with construction windows typically June through September and 40–60 calendar day completion periods. Davis-Bacon prevailing wage requirements, Build America Buy America Act compliance, Buy Clean Colorado Act emissions standards for materials, MSHA mine safety training, and White-Nose Syndrome decontamination protocols are standard conditions across Colorado solicitations.

Colorado's Division of Reclamation, Mining and Safety appears as the dominant repeat buyer, with named projects including Wandering Prospector (multiple bidding rounds through July 2, 2026), Madonna (June 24 and later deadlines), Walsen (June 24), Dream Canyon (May 6), Querida Phase 2 (May 13), Twin Sisters (June 2), Bobcat LaPorte Uravan NRD (May 13), Maggie Gulch (April 30), and BPMD Plus (April 30), all issued as Request for Documented Quotations (RFQs) or Invitations for Bid (IFBs) with mandatory pre-bid meetings and electronic submission via Colorado Vendor Self Service. Representative opportunities outside Colorado include Greenville County, South Carolina issuing IFB #25120 for Laurel Meadows Stream Restoration and Riparian Buffer Reclamation (due June 6, 2025, now past deadline), the Georgia World Congress Center Authority seeking Olympic Cauldron restoration and installation services (RFP due July 13, 2026), and multiple Florida county projects for bridge replacement (Orange County), dune restoration (City of Sarasota), retention pond work (Marion County), historic pavilion repair (Florida Department of Environmental Protection), and masonry restoration (Monroe County). Performance and Labor Material Bonds at 100 percent of contract value, 5 percent bid preferences for Service-Disabled Veteran-Owned Small Businesses, and 5 percent retainage withheld until completion are standard across the code; liquidated damages typically run $400–$1,000 per day for schedule delays.
