NIGP 92545: Geological Engineering

NIGP 92545 Geological Engineering is an Item code for independent cost estimating, geotechnical investigation, and materials testing services that state and local governments procure to support transportation infrastructure, utility systems, and environmental remediation projects. Recent solicitations show demand for contractor-style production-based cost estimating for alternative delivery and public-private partnership projects; subsurface investigation and materials laboratory testing for construction quality assurance; hydrogeologic consulting for aquifer storage and groundwater resource management; preliminary engineering and design services for stormwater and wastewater infrastructure; and construction engineering and inspection oversight across transportation, water, and environmental remediation work.

Issuing bodies across the code span state transportation departments (Georgia DOT), county utilities and public works departments (Pinellas County Utilities, Madison County, Chatham County), cities (Fort Myers, Santa Fe, Rio Rancho), regional authorities (Harris County Flood Control District, San Antonio River Authority), and special-purpose districts (Rome Floyd County Development Authority). The Georgia Department of Transportation appears as a frequent and high-volume buyer, posting multiple solicitations for independent cost estimating, general engineering consulting, and construction engineering inspection services supporting alternative delivery programs and specific corridor projects. State and local geographic spread includes Georgia (GDOT procurements across multiple regions), Florida (Pinellas County, Sarasota County, Orange County, Fort Myers, Broward County), Texas (Harris County, San Antonio, Railroad Commission), and scattered municipal activity in New Mexico, North Carolina, and other jurisdictions. Representative recent opportunities include the Georgia Department of Transportation's RFQ 484-111626 for Independent Cost Estimator services supporting the I-285 East Express Lanes Public-Private Partnership project, with qualifications due November 16, 2026 (RFP notice type); the City of Fort Myers' RSQ 25-054 for material testing services on a continuing as-needed basis, due May 23, 2025, requiring Florida Professional Engineer licensure and three years' consecutive business history; Pinellas County Utilities' RFQ 26-0616-CCNAC for hydrogeologic consulting services with a five-year contract term and estimated value of $5 million, proposals due August 11, 2026; and the New Jersey Department of Environmental Protection's RFQ T2621 for remedial investigation and design services, quotes due November 20, 2026, requiring Licensed Site Remediation Professionals and compliance with NJDEP quality assurance and health and safety plans.
