UNSPSC 81151900: Geophysics

UNSPSC 81151900 Geophysics is a Class code that encompasses technical analysis of subsurface geology, aquifer characterization, and geophysical data interpretation for water resource planning and environmental assessment. State and local governments procure this work primarily through water authorities, regional development boards, and municipal utilities seeking to evaluate groundwater production zones, map subsurface formations, and support long-term water supply planning. The work involves geophysical logging analysis, GIS-based subsurface mapping, hydrogeological modeling, and technical reporting by licensed professional geoscientists. Issuing bodies are concentrated among state water agencies and higher education coordinating boards rather than general-purpose municipalities.

The Texas Water Development Board posted the most representative recent opportunity—a brackish groundwater production zone analysis for the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers across fourteen central Texas counties, with proposals due August 6, 2026. The TWDB RFP requires ten years of project management experience in advanced scientific studies, professional geoscientist licensure, expertise in geophysical log documentation and GIS subsurface mapping, and a subcontracting plan targeting VetHUB vendors. The contract runs through August 31, 2027, with potential renewal through August 31, 2030, and evaluation weighted 40 percent on technical proposal quality, 25 percent on team qualifications, 20 percent on relevant experience, and 15 percent on price. All recent activity identified in the source derives from Texas procuring bodies, with no demonstrated spread across other states in the dataset.
