Exchange of data on buried infrastructure

In Denmark, there is about 750,000 kilometres of buried infrastructure in the form of tubes, cables and wires. In total, this supply network supplies Denmark with electricity, gas, district heating, water and telecommunication services and purchase of waste water.

We, as a community, have quite a good overview of the above-ground infrastructure such as roads, masts, railways etc., but we can do more to get an overview of buried infrastructure. 

Today wiring maps are of varying quality and exist in various formats from fully digital data to old maps made by hand.

Wiring maps are the internal tool of utility companies for the operation and maintenance of their transmission network and at the same time, they form the basis on which entrepreneurial companies and excavation companies make their excavation planning. The better wiring maps, the less excavation damage.

Excavation damage costs the society DKK 2.8 billion over a period of 10 years. When a subsoil wire or cable is dug out, we, as citizens and businesses, also experience problems as to security of supply. So, it is worth the while to have a grip on the positioning of subsoil tubes and cables.

The Danish Register of subsoil Cable Owners (LER) has for 10 years been supported by the exchange of wiring maps. In that period, more than 8 million wiring maps have been delivered. However, modern technology and IT mean that time is ripe for an investment in a fully digital exchange of uniform digital wiring maps. As part of the joint public digital strategy 2016-2020 the existing digital platform is improved to make it easer and faster for contracting companies and excavator actors to get access to necessary information before excavating.

The excavation actors will in the future have less problems when juxtaposing wiring cards as part of the preparatory excavation work and the fast exchange will support urgent excavation. The initiative also supports the coordination of excavation works by opening a new possibility to facilitate the coordination of excavation work. In general, we will all benefit from this initiative in the form of increased supply security, less excavation mistakes, more efficient excavation and thus less traffic congestion. 

Good, coherent data on the subsoil infrastructure give companies new business options as to development of new, innovative solutions. Furthermore, data will make existing work-procedures relating to maintenance more efficient, and such data will increase the use of existing infrastructure.

The government will benefit more from the supply sector and with this initiative we continue working on making the supply sector more efficient and on ensuring crosswise synergy.
