Underground utility mapping

Our expert utility mapping service is the ideal solution for local authorities, cities, businesses and individual customers, enabling them to carry out their land development, urban planning and construction projects with precision and in compliance with regulations.

What is underground utility mapping?

Underground utility mapping is the process by which the geographical information about a buried network (water, electricity, gas, telecommunications) is associated with precise coordinates on the ground. This approach involves the use of cutting-edge technologies to establish the precise spatial location of detected networks and generate accurate maps of underground structures.

It is an essential method for ensuring the safety of construction work. Since the implementation of the “DT/DICT anti-damage” reform of July 1, 2012, all network operators are required to provide network maps.

Bringing networks into compliance

City councils must restructure all networks they own in compliance with the Declaration of Intent to Start Work (DICT) with Class A accuracy: 0.40 cm for rigid materials and 0.50 cm for flexible materials.
