Q: Why do I need an underground utility detection (UUD) survey ?
A: It allows you to find out whats buried without any digging. This non-invasive method of detection is crucial in avoiding costly damages to assets or injuries/loss of life during 'blind' excavations.
Q: Is it really necessary ?
A: Local authority of certain high-density areas (e.g. Kuala Lumpur, Penang and Johor Bahru) may require UUD data to be submitted as part of the as-built survey in the application for a Development Order (DO). A recent customer inquiry involving a factory development in Subang shows that other municipal councils are imposing similar requirements.
Q: Can Jurukur Perunding do a UUD survey ?
A: Several JUPEM guidelines are evident of such work being undertaken by land surveyors. Work undertaken by our company can be endorsed by one of our licensed land surveyors.
Q: What can you detect ?
A: We can typically propose suitable methods of acquiring non-intrusive information on buried structures (up to a depth of about 10 feet) using a combination of equipment such as electromagnetic locators and ground penetrating radar. Things we can detect include:-
- Metal objects ( e.g., pipes, tanks )
- Asphalt thickness ( layer of road surface material )
- Water body ( e.g., leaks and water table )
- Non-metallic objects ( suitable cables using flexi-trace )
The timing of survey is crucial (for example, high water content during the monsoon season will affect the results).
