 Road tunnels and technology in an operational perspective
Arild Petter Sovik, Tunntech Global News

20 - 23 February 2018, Gdansk, Poland.                          

Providing a safe and sustainable winter road service and a focus on new challenges and experience gained in winter road and motorway maintenance is the topics for this winter congress. Representatives of various levels of government administration, associations and road agencies, European and World experts, as well as academics and equipment manufacturers have an opportunity to develop common standards, based on varied experiences and many years of practices, and enter into close bi- and multilateral cooperation. 

12 - 14 June 2018, Graz, Austria.                          

This international symposium offers the possibility to exchange knowledge and to gain deeper insight into the newest developments in the fields of ventilation, risk analysis, system tests for the commissioning of road and railway tunnels, operational experience of road und railway tunnels and refurbishment and upgrading of tunnels under operation. 

13 - 15 June 2018, Luzern, Switzerland.                          


The Fehmarnbelt tunnel is set to become the world’s longest combined car and rail tunnel. There is still approvals missing before the project is finally approved by all authorities. The German government approval of the Fehmarnbelt link is expected by mid 2018 according to the Danish Ministry of Transport, Building and Housing.

The point cloud created by the laser scan is mainly used to evaluate the conditions of the pavement but can also be used to gather data from the side area and the tunnel walls. The report from such a scanning gives the necessary data for analysis and give the tunnel operator a chance to follow up the development of the road surface, the rock conditions and the construction, from one year to another. 

BIM helps you to anticipate issues, assess information, and act more confidently at each stage of your tunnel design project. Minimize rework and improve predictability for design and construction of complex structures as tunnels. If you can add scheduling data to your information model and to the different components, generating accurate programme information and enabling step-by-step visuals of the project’s development. This process is known as 4D BIM.

Already in the autumn of 2017, the first tenders will be announced in the longest and deepest road tunnel (subsea) construction in the world. The tunnel starts in Harestad (south) to Arsvagen (in north), and will be over 25 kilometers long. In addition a 2 kilometer ramp up to Kvitsoy will be build. E39 Rogfast is an important step in the development of the coastal road between Kristiansand and Trondheim. E39 coastal road is part of the overall transport network in the country. The coastal road is about 1000 km. This represents one-seventh of the total main road network in Norway.

Several bicycle/pedestrian tunnels have been build in the world. There is now available new knowledge and understanding of how a bicycle/pedestrian tunnel has to be constructed and equipped to be a safe expressway for pedestrians and bicycles.
