NIGP 92569: Mining and Mineralogy/Engineering

NIGP 92569 Mining and Mineralogy/Engineering, an Item code, encompasses architect-engineer and engineering-related design, project administration, and construction-phase services that state and local governments procure for capital improvement, maintenance, facility assessment, and infrastructure projects across multiple disciplines including structural engineering, cost estimating, flood control, geotechnical analysis, materials testing, mechanical and electrical systems, power generation infrastructure, surveying, and renewable energy feasibility. The recent opportunity mix reflects issuing bodies across large county public works departments, flood control districts, airport authorities, and municipal engineering offices, with the County of Orange and its Orange County Flood Control District dominating the recent posting activity through multiple concurrent pre-qualification solicitations for architect-engineer task order contracts across specialty disciplines. Work is procured on an as-needed, time-and-materials basis through Qualified Vendor Lists and individual Contract Task Orders, with no guaranteed minimum work volume and three-year contract terms typical across most solicitations. Evaluation criteria consistently weight qualifications and related experience at 40 percent, key personnel and staffing at 15–20 percent, availability to perform services at 20–25 percent, and response organization and model contract compliance at the remainder.

Geographic activity concentrates in California (particularly Orange County) and Georgia, with recent opportunities from Chatham County, City of Griffin, City of Social Circle, DeKalb County, Madison County, Ada County (Idaho), and the City of Madison (Wisconsin). The County of Orange has posted approximately ten active RFQs in the past four months, including Architect-Engineer structural engineering services (RFQ due December 4, 2026), contract administration and building assessments (RFQ due November 5, 2026), airport materials testing and inspection services with 25 percent SBE participation goal (RFQ due April 24, 2026), architectural services QVL (RFQ closed October 1, 2026), and cost estimating design support services. Georgia Department of Transportation is soliciting General Engineering Consulting and Owner's Verification Firm services for the I-75 South Express Lanes project (SOQ due August 24, 2026). Chatham County released a design engineering consultant RFP for pavement and drainage reconstruction on Wahlstrom and Forbes Roads with a September 8, 2026 deadline. The California Department of Technology on behalf of the State Water Resources Control Board is procuring WaterTAP 2.0, a cloud-based SaaS solution for drinking water compliance consolidation, with Phase 1 proposals due December 2, 2026 and a base contract term of three years. Activity skews toward qualifications-based procurement using RFQ and RFP vehicles for establishment of multi-discipline pre-qualified vendor lists rather than single-project competitive solicitations.
