NIGP 92569: Mining and Mineralogy/Engineering

NIGP 92569 Mining and Mineralogy/Engineering, an Item code, encompasses architect-engineer services for geotechnical investigation, materials testing, site characterization, and reclamation design work that state and local governments procure for infrastructure, environmental remediation, and facility projects. Recent solicitations show state and local jurisdictions buying geotechnical reports, soil and asphalt testing, construction inspection, landfill design and permitting support, abandoned mine reclamation engineering, and preliminary design and feasibility assessment for renewable energy and water infrastructure projects.

The issuing bodies are primarily county public works departments and regional special-purpose districts, notably Orange County, Florida (which has posted multiple A-E task-order RFQs for geotechnical, materials testing, flood control engineering, green infrastructure, and landfill services since April 2026) and state transportation and environmental agencies including the Georgia Department of Transportation and the State of Utah Division of Oil, Gas and Mining. Geographic activity concentrates in California (Orange County leading), Georgia (GDOT and multiple cities), and Utah, with secondary activity in Florida. Representative recent opportunities include the County of Orange RFQ 0803026003RE for Geotechnical & Materials Testing Services–A-E Task Order Contract (due May 15, 2026, RFQ establishing a three-year QVL for time-and-materials task orders across the county and flood control district); the State of Utah Kenilworth Mine Fire Project RFSQ JH2639 (due February 26, 2026, seeking engineering and reclamation design for abandoned mine hazard mitigation with Phase I and Phase II investigation reports and bid-ready construction specifications due November 30, 2026); the County of Orange RFQ for Prima Deshecha Landfill Renewable Energy Preliminary Design RFP2993063702AR (RFP issued July 1, 2026, with mandatory pre-bid site visit June 10, 2026, requesting preliminary design and feasibility assessment of a landfill gas-to-energy facility targeting 2030 operational start with 540-day schedule); and the Georgia Department of Transportation RFQ 484-041726 for Construction Engineering Inspection services at the State Route 25 Darien River bridge (due April 17, 2026). Compensation is typically time-and-materials or cost-plus structures with no guaranteed minimum work volume; California prevailing wage compliance is required where applicable.
