An Enterprise Pipeline was in potential danger from the installation of drilled piers on a new highway overpass. Best records showed this pipeline to be 50 foot deep but the actual location was not known. Previous locating efforts over an 8 month period had included excavation of a 50 foot deep Test Hole (which didn’t find the pipe) and a smart pig. Enterprise asked BBI to use their 3D Designation Technology to find the vertical and horizontal location of the line. Over a 3 day period BBI was able to designate the line and create a profile drawing that showed the where the pipeline existed and showed where the proposed piers were located.
