Applicability of electrical resistivity tomography in subsurface utilities engineering

Abstract

This paper presents the applicability of Electrical Resistivity Tomography (ERT) in Subsurface Utilities Engineering (SUE). The objective is to use pseudosection generated by ERT to located known subsurface utilities. For construction industry, the investigation of subsurface utility is essential to avoid unforeseen condition that may cause project delay. According to the result, performing ERT using fundamental tester in this study is not suitable to locate subsurface utilities, however it can locate the loose part of the ground which likely to indicate the location of subsurface utilities. Therefore, ERT exhibits potential to be used before the actual subsurface utilities mapping to simplify the work of gathering information to locate the subsurface utilities accurately.
