Utility strikes during construction are a tragically common occurrence, resulting in damage to underground infrastructure, costly repairs, project delays, and safety hazards. Even with the nationwide 811 “call before you dig” program, some underground utilities remain undetected. Electromagnetic locators can help, but a tool is still needed to locate non-metallic utilities.
In this video, Simon Pedley, detection specialist for Leica Geosystems, part of Hexagon, shows how the Leica DSX ground penetrating radar provides a solution for underground utility detection. With the DSX, you can easily locate non-metallic lines and transmit that information to excavators to create avoidance zones. Simply by pairing the DSX with GPS and walking around the site in a grid pattern, you can obtain a heat map showing the exact location and depth of the utility lines beneath the surface. This map can easily be exported as a PDF, DXF, DWG, or even straight to machine control guidance systems.
One of the newest capabilities of the DSX is that now you can look at the B-scan images to see buried objects in a 2D graph called a radargram. This information gives you more insight on how the system does interpretations and what it sees in its algorithms.
