A labyrinth with streets and alleys, houses and walls, the new city is. However, as complicated as cities are on the surface, the situation underneath the ground can be much more confusing: electricity, telephone and fibre optic cables compete with water and gas, wastewater drains, and sewage pipes for space. Further complicating the problem, new facilities are continuously being installed and existing systems are moved, with layers of facilities dating back as far as the 19th century, both in and out of use.

For contractors to excavate, discovering buried utilities during excavation will result, at best, in expensive delays and financial or other penalties where services are disrupted; at worst, this scenario carries the risk of injury or even death to staff.
Therefore, before contractors begin excavation at a site , it is important that they make every effort to identify and locate all buried utilities that are likely to be impacted by planned excavation or construction. Second, this would definitely include calling a provider “before you dig.” These services gather information from utility providers about the location of buried infrastructure and pass this data on-usually at a cost-to contractors who excavate.
Although utility monitoring services provide the contractors with an important first philtre, they are not infallible: maps may be incomplete or inaccurate; utilities may have been added, removed or relocated without passing on the information. For this purpose it is advisable to employ the services of suitably trained , skilled and fitted utility surveyors and a utility mapping service for excavating contractors.
Using current methods and technologies such as electromagnetic detectors, radiodetection, and ground penetrating radar systems (GPRS), a wide variety of underground facilities, including metallic and non-metallic pipes and cables, can be accurately identified. Then these services can be mapped using a combination of conventional survey methods, GPS, and applications for geographic information systems ( GIS).
