UNSPSC 71112119: Resistivity logging services

Use of neutron porosity logging to identify zones of porosity.

UNSPSC 71112119 Resistivity logging services is a Commodity code that in practice covers on-site surveying, characterization, and monitoring services for subsurface conditions in municipal infrastructure projects. The code shows minimal alignment with recent state and local opportunities — of the four posted solicitations tagged under it, only one involves direct subsurface surveying work (the Dalton-Whitfield Solid Waste Authority's landfill gas collection system expansion, which requires surveying of gas extraction well locations). The other three opportunities span irrigation system installation (City of DeBary, Florida), digester gas utilization infrastructure (Eastern Municipal Water District, California), and executive search services (City of College Park, Georgia), none of which represent core resistivity logging or subsurface characterization activity. The code appears to serve specialized environmental and utility infrastructure work that issuing bodies tag inconsistently — municipal solid waste authorities, water reclamation districts, and cities conducting infrastructure expansion or conversion projects that may include subsurface investigation as a minor component rather than a primary scope.

The geographic spread across the recent opportunities is limited and geographically dispersed: Georgia, Florida, and California. The single relevant solicitation—the Dalton-Whitfield Solid Waste Authority's ITB posted April 17, 2026, with a May 21, 2026 response deadline—is a $2,000-per-day liquidated-damages landfill gas collection project requiring Georgia-licensed general contractors with five years' minimum experience and 50 percent on-site labor. This code shows sparse recent activity in state and local procurement and does not align clearly with current buying patterns; procurement offices appear to be tagging infrastructure projects under it inconsistently, suggesting that resistivity logging services as a discrete commodity do not drive regular, predictable state and local demand.
