- Type C: On-site Reconnaissance
An on-site visual inspection to confirm asset information against physical utility features such as street lights or valves.
- Type B: Utility Detection Locates all utilities in the designated area using methods such as Electromagnetic Location or Ground Penetrating Radar which can then be marked out where required.
- Type A: Intrusive Visual Inspection
Post-utility detection, verification by intrusive excavation or by noting physical utility features in manholes or inspection chambers.
