A Utility Locator should be used to locate utilities before excavation begins. Whether it is on a right-of-way, private property or on a construction project, it is important to know what lies beneath the surface. There are many conditions that make it difficult to determine what has gone on in the past ...drawings and as-builts get lost, ...as-builts are not updated as installation conditions require repositioning of utilities or services, ...utilities and services are installed without tracer wires or trace mechanisms. All of this can make it difficult to know what lies ahead of the excavation without a utility locates survey. GPR can locate both metallic and non-metallic pipes and cables. This provides a complete picture of the underground, and helps to ensure that nothing was missed using traditional locate methods.
