UNSPSC 81102000: Mining engineering

UNSPSC 81102000 Mining engineering is a Class code whose nominal scope—geological survey and mineral-extraction design—does not align with the state and local opportunities currently posted against it. The recent solicitations tagged with this code span architect-engineer services for flood control, geotechnical testing, landfill operations, renewable energy feasibility, roadway design, airport planning, materials inspection, wastewater treatment, green infrastructure, and power generation systems. None of these activities involve mining, mineral assessment, or extractive-industry engineering. The code shows little relevant recent activity; the mismatch between the code's stated scope and the work actually being solicited suggests either a data-entry error in the procurement system or a fundamental misalignment between how issuing bodies classify their architect-engineer procurements and UNSPSC's taxonomy structure.

State and local entities issuing under this code are primarily the County of Orange (California), through its Public Works Department and Flood Control District, along with single opportunities from the Georgia Department of Transportation, City of Union City (Georgia), City of Nicholls (Georgia), Madison County (Georgia), Orange County (Florida), the City of Cedartown (Georgia), and the State of Utah Division of Oil, Gas and Mining. The County of Orange dominates the recent activity, with multiple RFQs for architect-engineer task order contracts posted in June and July 2026 covering disciplines as diverse as flood control hydraulics, cost estimating, mechanical and electrical design, land surveying, project management support, and geotechnical analysis. Recent representative opportunities include the County of Orange's RFQ for Architect-Engineer Flood Control Engineering Services (due August 13, 2026), the Georgia Department of Transportation's RFQ for General Engineering Consulting and Owner's Verification Firm services on the I-75 South Express Lanes project (due August 24, 2026), and the County of Orange's RFQ for Architect-Engineer Green Infrastructure Services (due May 15, 2026). These procurements use multi-award qualified vendor list structures on a time-and-materials basis with no guaranteed minimum work volume, three-year initial contract terms, and evaluation weighted heavily toward qualifications and experience. The code's presence in the recent-opportunities dataset appears to be a classification artifact rather than evidence of actual state or local demand for mining-engineering services.
