UNSPSC 72101515: Subsidence service work

Repair work done to structures damaged or threatened by sinking soil.

UNSPSC 72101515 Subsidence service work is a Commodity code covering excavation, stabilization, and remediation of unstable subsurface materials beneath public infrastructure caused by abandoned mines, sinkholes, or similar subsidence events. State and local governments use this code to procure contractors for mine-shaft stabilization, abandoned-mine-land (AML) remediation, and roadway protection work where underground voids threaten surface infrastructure integrity. The work typically includes excavation to depth, installation of concrete plugs or fill material, debris removal, backfilling, pavement restoration, and site remediation. Issuing bodies span state environmental and natural resources departments, counties, cities, and water authorities. The Illinois Department of Natural Resources appears as a repeat buyer under the AML program; water and utilities authorities also solicit under this code for infrastructure protection. Geographic activity concentrates in Illinois (with OSMRE-registered AML projects), Georgia, Florida, Texas, Colorado, Connecticut, South Carolina, and Oregon based on recent opportunities. Issuing bodies include state agencies (Illinois DNR, Georgia DOT), county governments (Mecklenburg County, Orange County, Fayette County), municipalities (cities of Santa Cruz, North Miami Beach, Cumming), water authorities (Cherokee County Water & Sewerage, Palm Beach County Water Utilities, Douglasville-Douglas County Water & Sewer Authority), school districts (Prescott Elementary), and transit authorities (Broward County Aviation).

Representative recent opportunities show mixed scope. The Illinois Department of Natural Resources posted AML 2516 CW & V E Mine Shaft Subsidence (IFB, July 21, 2026) for excavation and stabilization of an abandoned mine shaft beneath a roadway in Braidwood, Illinois—approximately 180 cubic yards of material removal to 15–20 feet depth, 30 cubic yards of IDOT Class SI concrete plug installation, asphalt restoration, and mobilization/traffic control. Cherokee County Water & Sewerage Authority solicited the Etowah River Water Treatment Plant Intake Modifications (pre-bid July 16, 2026, bids due August 6, 2026) for intake piping extension, structural support, and riverbank stabilization. Orange County, Florida posted Horizon West Trail - Phase 1A (bids due August 13, 2026) at $5.66 million, including a 0.668-mile multi-use trail with a prestressed-concrete-pile-supported boardwalk and utility improvements. Other recent solicitations under this code include erosion stabilization (Fayette County, Georgia; Kenwood Park, bids due July 28, 2026), stormwater detention basins (Harris County Flood Control District; Williamson County, Texas), and landfill-cell construction (City of Brownsville; Augusta, Georgia). Activity is steady across mid-2026, with response dates clustered in late July and early August 2026. The code reflects genuine earth-stabilization and subsidence-remediation work where recently posted opportunities align closely with the code's nominal scope.
