Utilities are not the only conflict lurking underground.
Advances in array tech data collection and software processing are mainstreaming the platform for use by a diverse range of professionals such as geomatics/geospatial surveyors, engineers, and geoscientists as the technology provides a comprehensive “view” of the underground. In fact, coming soon is ASCE 38-21 which is the long-anticipated update to 38-02. The title for 38-21, Standard Guideline for Investigating and Documenting Existing Utilities increases the scope for Subsurface Utility Engineering (SUE) investigations to include additional conflict information regarding the subsurface. An important addition is the inclusion of Multi-Channel GPR (MCGPR) and its integration into the process. The use of MCGPR arrays is proven to be the most effective method to obtain information of the overall utility corridor rapidly and there is no equivalency to any 2D GPR process-period.
