A Utility Search, also known as a C2 Utility Search or PAS128 (D) utility search, is the initial step in identifying utility asset owners and locating their buried and overhead assets and apparatus. A Utility Search is essential for development projects as it provides valuable insight into the presence and location of underground and overhead ...
The other is to locate a signal that is applied AKA an Active signal , [7] are called the Passive Utility Detection and Active Utility Detection. It’s important to note, however, that while both methods can help locators distinguish an underground utility, they do not confirm its presence nor its absolute location.
Borehole radars utilizing GPR are used to map the structures from a borehole in underground mining applications. Modern directional borehole radar systems are able to produce three-dimensional images from measurements in a single borehole. [8] One of the other main applications for ground-penetrating radars is for locating underground utilities.
A utility tunnel, utility corridor, or utilidor is a passage built underground or above ground to carry utility lines such as electricity, steam, water supply pipes, and sewer pipes. Communications utilities like fiber optics , cable television , and telephone cables are also sometimes carried.
A chart showing different underground utility locating cart systems. 3D mapping can be accomplished when several individual passes are combined and interpolated. All of the systems and antennas manufactured by US Radar are capable of having their data presented in 3D format with the appropriate software packages.

Underground and underwater crossings may be a practical alternative to crossing rivers. For example, as of 2024, the Public Service Commission of Wisconsin determined that the installation cost of a 69-kilovolt aboveground power line is $284,000 per mile. In contrast, an equivalent underground line costs $1.5 million per mile.
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 ...
