Project Description

The project scope entailed provision GPR underground utility scanning and survey services at Nairobi railways. The underground utilities surveyed and mapped include water pipes, sewerlines, electric cables, telecommunication cables, buried tanks, manholes, water hydrants among others. The US Radar Q5 GPR fitted with a Windows tablet controller installed with data collection software was calibrated before deployed for field data collection. As well, the Stonex GNSS was utilized to pick the (x,y,z) location coordinates of the utilities whilst GPR recorded the location and depth of the utilities. GPR data processing was also done using Radar Studio including removing noise from GPR data, plotting underground utility and topographical maps, CAD drafting, preparing project report as well as training of the client’s surveyors.
