Application of Ground Penetrating Radar for Underground Utility Detection

Abstract

The accurate location of underground utilities at a construction site can prevent any damage to the utilities during excavation works. The cost of fixing the damage utilities can be very costly and will reduced the expected profit of the construction works. Therefore underground utility detection using Ground Penetrating Radar (GPR) is important in providing accurate information of the utilities at a construction site. In this study TerraSIRch SIR-3000 GPR equipment have been used to detect underground utility, with a 400 MHz ability which can reach up to 3m depth. RADAN 7 software is used to interpret and analyze the GPR data. Based on the results obtained the GPR equipment is capable of detecting underground utilities such as pipe, cable, shaft, etc.. The detected utilities are then shown in the 2-D and 3-D drawing for better visualization and identification.
