UNDERGROUND UTILITY SURVEY OF PART OF AN INDUSTRIAL AREA, PORT HARCORT, NIGERIA

This project is termed 'Underground utility survey of part of an Industrial Area Port Harcourt, Nigeria '. The accurate location of underground utilities at a construction site can prevent any damage to the utilities during excavation works. The means 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 within the project site. In this study a USS RADAR-3000 GROUND PENETRATING RADAR equipment was used to detect underground utility, with a 400 MHz ability which can reach up to 6m and 60m depth depending on the purpose and mode of operation. 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. The project entails reconnaissance, Scanning, Using GPR (GROUND PENETRATING RADAR) and DGPS (Differential Global Positioning System) for positioning of the buried utility. Both equipment was used simultaneously, the plan was produced using ArcGIS 10.5 and Auto-Cad civil 3D. Data downloading for both GPR and DGPS was done using Radan software and windows mobile software.

The results of this study demonstrates the effectiveness of GPR for underground utility mapping. GPR is a quick and easy way to map the location of underground utilities, and it can help to prevent costly and dangerous accidents during excavation.
