Abstract Underground utility refers to any below-ground line, installation, or structure used by a service or utility provider. Underground utility inspection is a process of examining the designated area that needs to be inspected in detail. The purpose of the inspection is to ensure that the underground utility is in good condition and to check for any faults. By using the ground penetrating radar (GPR), the technology can capture images below the surface of the ground using radio waves. The various data through previous references are used to discuss and analyse the capability of GPR for underground utility inspection to ensure its gives the best performance for the inspection. GPR technology has become an essential tool for locating buried utilities and preventing damage and accidents during construction projects. This paper explores various advancements in GPR technology, including data processing methods and scanning techniques, to improve the accuracy and effectiveness of underground utility mapping. The research presented in this paper highlights the abilities of GPR to inspect underground utilities. The GPR data used in this project was collected from the evaluation and verification facility (EVF) in the Malaysia Nuclear Agency. The accuracy of these predicted positions was validated from GPR data and compared with as-built drawings from the contractor. The alternative analysis approaches that could be applied to improve the GPR accuracy when the optimum conditions are not met are also discussed.
