NIGP 92546: Geotechnical Engineering

NIGP 92546 Geotechnical Engineering, an Item code, encompasses soil investigation, subsurface exploration, laboratory and field testing, geotechnical analysis, and materials inspection services that state and local governments procure as precursor work for infrastructure, building, and remediation projects. Recent solicitations show state transportation departments, county public works agencies, cities, and universities contracting for geotechnical investigation and certification services tied to roadway design, water system upgrades, landslide stabilization, stormwater drainage, site remediation, and facility construction. Issuing bodies span state departments (Georgia Department of Transportation, New Jersey Department of Environmental Protection), county governments (Denton County, Dawson County, Lewis County, Hillsborough County, Washington County, Forsyth County, Orange County, Pinellas County, Brazos River Authority), cities (Orlando, Winder, Cincinnati, Augusta, San Marcos, Casselberry, Brownsville), universities (Texas A&M, Sam Houston State, San Diego State, UCLA), and school districts (Hutto ISD). Georgia leads recent activity through multiple GDOT independent cost estimator, construction engineering and inspection, and alternative delivery program solicitations. State and local bodies are establishing standing panels of two to five firms on on-call contracts with task-order execution, typically structured on an hourly rate or negotiated lump-sum basis per work order, with contract terms spanning one to five years. Mandatory qualifications include state professional licensure (PE or PG), minimum years of relevant experience (commonly five to ten years), compliance with E-Verify, and specialized certifications such as Quality Assurance lab certification or nuclear density gauge credential.

Recent representative opportunities include the Georgia Department of Transportation's RFQ for Independent Cost Estimator services in support of alternative delivery and P3 projects—particularly the I-285 East Express Lanes project (responses due November 16, 2026)—requiring ten years of production-based estimating experience with HCSS software; Dawson County Board of Commissioners' RFP for on-call geotechnical services including soil borings, subsurface exploration, materials testing, and NPDES compliance (responses due November 12, 2026); Denton County's as-needed materials testing and geotechnical services solicitation (responses due October 29, 2026); Hillsborough County's $6 million miscellaneous subsurface investigation and testing contract with estimated four-year term (responses due November 3, 2026); Washington County, Oregon's geotechnical and materials testing services procurement requiring ODOT Quality Control Laboratory Certification with a $300,000 five-year maximum (responses due October 14, 2026); and the City of Orlando's continuing geotechnical and materials testing services panel of multiple firms funded through Orange County Community Development Block Grant disaster recovery provisions (responses due October 14, 2026). Geographic spread centers on Georgia, Florida, Texas, Oregon, and Washington, with additional activity in Ohio, California, and the Northeast. Work locations range from regional statewide transportation networks to site-specific municipal and university facilities.
