Ground penetrating radar is one of the non-destructive methods useful in locating underground facilities. Little researches had been investigated about the significances of measuring pipes and cables in Hong Kong. In this research, general procedures on how to design the grids and to conduct the radar surveys were reviewed. The main objective was to compare the radar results with the conventional survey methods in three trial sites. Finally, it was crucial to evaluate the use of antenna frequency and the accuracy of the obtained data.
