Dedicated Locator

Take control of your project and reduce downtime.

A dedicated locator enhances the efficiency of the locates process by having a single locate service resource (Dedicated Locate Service Provider – DLSP) contracted by the Project Owner to locate all underground infrastructure on a project.  It is paving way for large and long-term scale projects to have continual delivery of locates when and where they are needed.

Dedicated locator is a new legal concept that was introduced through a law amendment in April 2022.


What is a Dedicated Locator?

A Dedicated Locator is a single resource used to mark all underground infrastructure within a project area.

Benefits of a Dedicated Locator:

  • Improves productivity
  • Reduces downtime as the locates are completed under the direction of the Project Owner
  • Promotes damage prevention and safer excavation practices
  • More control – get locates when, where, and as often as your project requires
  • Provides flexibility when delays or conflicts require changes to project timelines or scope”
  • It frees up the regular pool of public locate service providers to complete standard locate requests for homeowners and less complex requests
  • Mediation – provides a platform to solve issues that arise within a project or region
  • Insights – gives all participants additional data from which to make current and future decisions
