Private utility locating requires access to the property and information about the planned work area so technicians can determine which underground utilities need to be investigated. Available site plans, utility records, as-built drawings, previous surveys, and information about known private utilities can help technicians understand existing infrastructure and focus the investigation.

The site should provide reasonable access for locating equipment, with unnecessary vehicles, equipment, debris, vegetation, and other obstructions cleared from the areas being investigated whenever possible. Depending on site conditions and the type of utilities present, technicians may use electromagnetic locating equipment, Ground Penetrating Radar (GPR), and other detection methods to trace underground lines. Soil conditions, utility materials, depth, surface conditions, and electromagnetic interference can affect detection results.

At Utility Locating & Mapping New Hampshire, we evaluate the project requirements and select appropriate locating methods for the site. Private utility locating can be combined with GPR Scanning, Utility Marking, Underground Utility Mapping, Concrete Scanning, and GPS/GIS Mapping to provide more comprehensive subsurface information. While professional locating can significantly improve site awareness, no detection method can guarantee that every underground feature will be identified, so appropriate excavation practices and verification remain important.
