UNSPSC 81151905: Field based geophysical survey consultants

Geophysicists apply the principles and concepts of physics, mathematics, geology, and engineering to the study of the physical characteristics of the earth and other planets. As a geophysicist, you would measure gravity and magnetic fields, seismic waves, temperatures, and natural electric current.

UNSPSC 81151905 Field based geophysical survey consultants is a Commodity code that captures expert analysis and fieldwork services for subsurface geological and hydrogeological assessment, though the recent opportunities posted under it show a significant scope mismatch — the code appears in a park irrigation installation project and an open educational resources technical assistance procurement, neither of which involve geophysical survey work. The one opportunity genuinely aligned with the code's nominal scope is the Texas Water Development Board's brackish groundwater production zone analysis for the Carrizo-Wilcox, Queen City, Sparta, and Yegua aquifers, which requires professional geoscientist licensure, ten years of hydrogeology experience in the project area, subsurface GIS mapping, and geophysical log analysis across fourteen Central Texas counties.

Activity under this code is sparse and geographically scattered. The TWDB brackish groundwater study represents the primary recent opportunity aligned with field-based geophysical surveying, with an RFP posted July 6, 2026, and proposals due August 6, 2026, anticipating contract start September 1, 2026. The contract runs through August 31, 2027, with potential renewal through 2030. TWDB requires a Subcontracting Plan demonstrating good faith effort with VetHUB vendors, professional liability insurance of $50,000 per occurrence and $100,000 aggregate, and sealed final reports from licensed Texas professional geoscientists. Award will be based on best value: technical proposal quality (40 points), team qualifications and experience (25 points), relevant project and government contract experience (20 points), and price (15 points). The other two posted opportunities—a city irrigation system upgrade in Florida and a higher-education OER grant support contract in Texas—do not represent relevant sourcing activity for firms in geophysical surveying or hydrogeological field analysis.
