UNSPSC 81151704: Geological exploration

UNSPSC 81151704 Geological exploration is a Commodity code that encompasses technical groundwater assessment, aquifer analysis, and subsurface mapping work for state water agencies and municipalities. The recent opportunities under this code show state and local governments procuring professional hydrogeological services including brackish groundwater production zone analysis, aquifer evaluation across multiple counties, GIS subsurface mapping, and geophysical log documentation. The Texas Water Development Board (TWDB) represents the primary recent buyer, soliciting comprehensive brackish aquifer analysis work requiring professional geoscientist licensure, advanced scientific study experience, and GIS subsurface mapping expertise. Work is performed by licensed professionals with specialized hydrogeology credentials and typically involves multi-year contracts with renewal options through cooperative agreements with state water authorities.

Recent activity centers in Texas, where the TWDB posted an RFP (58027RFP0003) on July 6, 2026, due August 6, 2026, for brackish groundwater production zone analysis across fourteen counties including Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers in Central Texas. The TWDB contract runs through August 31, 2027, with optional renewals through 2030, requires ten years of project management experience in advanced scientific studies, professional geoscientist licensure for all performing personnel, and mandates a Subcontracting Plan demonstrating good faith effort to utilize VetHUB vendors. A second opportunity in Florida—the City of DeBary's Rob Sullivan Park Irrigation Improvements (Bid 03-15, due April 10, 2015)—reflects less directly relevant activity, as it involved irrigation system installation rather than geological exploration or aquifer analysis. Geographic activity is limited to Texas in the near term based on recent solicitations, though the code's scope suggests potential applications across states with brackish groundwater assessment programs or aquifer management initiatives. The TWDB evaluation emphasizes technical proposal quality (40 points), team qualifications and experience (25 points), and relevant government contract experience (20 points), signaling that specialized hydrogeology credentials and prior work with state water agencies are material competitive factors.
