UNSPSC 81151902: Geophysical exploration

UNSPSC 81151902 Geophysical exploration is a Commodity code that captures subsurface analysis and characterization work state and local governments commission to evaluate aquifer resources, groundwater production zones, and related hydrogeological conditions. Recent opportunities show state water authorities and higher-education coordinating boards soliciting this work through RFPs for technical studies requiring professional geoscience licensure, advanced GIS mapping, geophysical log analysis, and hydrogeological modeling to support water-resource planning and grant administration.

The Texas Water Development Board is the primary repeat buyer visible in recent activity, having posted an RFP in July 2026 for brackish groundwater production zone analysis across the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers in fourteen Central Texas counties (Atascosa, Bastrop, Bexar, Caldwell, DeWitt, Fayette, Gonzales, Guadalupe, Karnes, Lavaca, Lee, Live Oak, Williamson, and Wilson). That solicitation, RFP 58027RFP0003, required respondents to demonstrate ten years of project management in advanced scientific studies, ten years in technology transfer, three years with TWDB databases and geophysical log documentation, and ten years of hydrogeology experience in the project area, with professional geoscientist licensure mandatory; proposals were due August 6, 2026, with an anticipated contract start of September 1, 2026 and a contract term through August 31, 2027, renewable in one-year increments through 2030. A Subcontracting Plan demonstrating good faith effort to utilize VetHUB vendors was required. Geographic activity appears concentrated in Texas; recent opportunities in this code do not show multi-state solicitation patterns or activity from counties or municipalities outside Texas water agencies.
