What is the purpose of underground utility mapping?

Underground utility mapping is to ascertain the most probable alignment of buried existing underground utilities and services. The detection work, carried out generally in conformity with the guidelines issued by the Department of Survey and Mapping Malaysia (JUPEM) will determine the presence of any buried power cables, metallic utilities (steel pipes, copper telecommunication lines and etc) and non-metallic utilities that are accessible (fibre optic cables, sewerage pipe and etc) using pipe and cable locators together with ground penetrating radar (GPR) equipment.


The range of underground mapping detection, accuracies, and the capability of detecting the underground utilities and services are dependent on the soil conditions and it may not always be possible for every utility (particularly the non-metallic ones) to be detected.


Underground utility mapping exercise is to reduce a risk of excavation or relocation works not a guaranty due to limitation and site condition. Cooperation between surveyors, project owner, stake holder and relevant authorities / property owners is helpful in obtain the accurate utility mapping.

What is the standard guideline for underground utility mapping in Malaysia?

What underground utilities can be detected?

​There are two categories of underground utilities which are metallic and non-metallic. To detect utilities in the metal category, where they can conduct electric current, Pipe and Cable Locator (PCL) tools are used to detect them. Below are among the types of utilities that can be detected using Pipe and Cable Locator.


  • Copper electric cables

  • Copper telecommunication cables

  • Metallic, iron gas / fuel pipes 

  • Metallic, iron water pipes

  • Metallic, iron sewerage pipes

  • Copper signal cables

  • Copper internet / TV cables

To detect utilities that are not metallic and cannot emit electric current, the tool used is Ground Penetrating Radar, also known as GPR. It can detect both metals and non-metals. This tool is usually used at the end of a job as a checking and also to find utilities that cannot be detected using PCL. However, the results of scanning using GPR are highly dependent on soil conditions. Not all utilities can be detected using this tool. Below are among the utilities that can be detected by GPR.

  • All detectable utilities use PCL

  • Fiber optic cables

  • Plastic (PVC), HDPE, asbestos cement (AC) gas / fuel pipes

  • Plastic (PVC), HDPE, asbestos cement (AC) water pipes

  • Clay (VCP), concrete sewerage pipes

  • Concrete pipes / culvert / drain

  • Plastic cable ducts
