Underground utility mapping was carried out using Ground Penetrating Radar (GPR) systems. This system was adopted after researching the various ground scanning options on the market, the site team found that this would be the best one in order to gather the necessary data required.
The GPR systems performed a full-ground scan including getting depths of all utilities in the vicinity, the ground make-up and the location of existing excavations. For example, the process gave accurate depth and location data for electric cables, water pipes, drainage pipes, telecom cables, and ducting.
The benefits of this system was immense. Using the system meant the site team could adopt a new method of completing the works using drilling. It reduced interruptions and day-to-day problems for our customers and motorists. It also kept the area tidy and clean, meaning we did not have to dig an open cut trench across one of busiest junctions in Newcastle City Centre. The system proved particularly invaluable at one location where open cutting on the public highway to locate the utilities was unacceptable.
