Locate Underground Utilities Checklist – GPR, Marking
✅ 22 items
Locate underground utilities is the first safeguard against costly strikes, delays, and service outages. This checklist guides teams through utility detection using records review, electromagnetic locating, and ground-penetrating radar, then marking services, establishing stand-offs, and implementing protection. It focuses on avoidance and verification only—no new utility construction is included. You will plan from as-builts and GIS, validate with GPR and EM methods, reconcile conflicts, and confirm critical depths with safe potholing or vacuum excavation. The workflow aligns with subsurface utility engineering practices to improve accuracy and reduce excavation risk. Acceptance cues, tolerances, and photo evidence are specified to ensure consistent results and defensible documentation across shifts and contractors. Use this interactive tool on live projects to brief crews, control plant movement, and maintain exclusion zones as conditions change.
