Underground utility mapping is used for positioning and identification of buried pipes and cables such as electric and telecoms beneath the ground. The technique prevents digging into or damaging any utility that may cause harm to the public or workforce.
It also enables utility mapping companies to reduce their project planning time, minimize risks, and assist in improving the quality of excavation works. Operators are using techniques such as electromagnetic, utility detection equipment magnetic, sonic/acoustic, GPR, live-line detector, and robotic crawler to detect, trace, and map buried utility lines. Mining companies are deploying underground utility mapping solutions, which are compliant with health & safety regulations. Due to advancements in the devices used for mapping, such as GPR and Global Navigation Satellite System (GNSS) locators, the creation of real-time 3D maps of buried utilities has become an easy task, further reducing inefficiencies, costs, and risks.
Subsurface utility engineering (SUE) refers to a branch of engineering that involves managing certain risks associated with utility mapping at appropriate quality levels, utility coordination, utility relocation design and coordination, utility condition assessment, communication of utility data to concerned parties, utility relocation cost estimates, implementation of utility accommodation policies, and utility design.
Ground-penetrating radar (GPR) is a geophysical method that uses radar pulses to image the subsurface. This non-destructive method uses electromagnetic radiation in the microwave band (UHF/VHF frequencies) of the radio spectrum, and detects the reflected signals from subsurface structures. GPR can have applications in a variety of media, including rock, soil, ice, fresh water, pavements and structures. In the right conditions, practitioners can use GPR to detect subsurface objects, changes in material properties, and voids and cracks.
