Private Utility Locating Services


Our team provides belowground private utility locating services in Washington, Idaho, Montana and Oregon. With advanced technology and highly trained professionals, we can precisely locate and map your entire utility system.

Public locators like 811 only locate utilities on public property, and they won’t provide depth. Private locators use multiple technologies to provide precise horizontal and vertical (depth) of belowground utilities, including unknown and abandoned lines.


The one-call system (811) is responsible for marking all publicly owned utilities. Typically, 811 does not mark depths and will not mark any privately owned utilities. Private construction projects likely have some or all utilities on site, and may include abandoned or unknown belowground features. To receive a comprehensive locate, you must utilize a private utility locating company to ensure that all buried utilities are located. The private locating process protects employees and equipment from potential line strike damages.

Accurate and up-to-date existing conditions are key to success for any construction project. We develop as-built drawings and facility maps during the planning phase of a project. Designs rely heavily on the precision of information obtained in the existing facility maps, which details the site’s underground infrastructure. With our in-house GIS technology and mapping services we can update existing or create new as-built drawings that portray actual site conditions – including any variations, renovations, or unknown pipes.
