Private Utility Locating in Minnesota

GPRS’ private utility locating services are meant to give your excavation team a detailed picture of what utility lines lie beneath the surface of your job site. To ensure the overall timely success of the job, utility detection is critical to any construction project where subsurface excavation is planned. If ignored, budget overruns multiply, your schedule turns chaotic and there’s risk of injuries taking place on your job site. The standard is one-call (811) utility locating, a state-sponsored public service that is required for every project. However, the scope of this service is limited to areas that only serve the public’s interest.

To achieve the complete success you're looking for, you’ll want to connect with an expert private service provider like GPRS.

Private Utility Locating: A Necessity for Every Subsurface Project

Before any project involving subsurface excavation commences, all underground utilities, including water, electric, storm, and sewer, must be located and identified in order to prevent line strikes and other accidents during the course of the project. Encountering an unexpected line or other object during excavation can result in costly damage, injuries to the crew, and unplanned increases in project costs.

Calling 811 before digging is an important first step. This number connects you to the national "call before you dig" line. 811 takes down your information and the location of your project, then lets utility companies know that they need to go to that location and mark the lines. However, 811 relies only on utility companies to let you know what is underground. If you only call 811, you may be missing information about private utilities, tanks, or lines, which is where a private utility locator company near you can help.
