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

Tunnels represents the most challenging part of an road infrastructure when it comes to the complexity of construction, technical infrastructure and technical facilities. But how should the road owner design, build, operate and manage the infrastructure to make sure that vulnerable parts of the road network remain reliable, available at all time, maintenance friendly for the operators and safe for the road users. A new trend defined as "Industry 4.0" is the current development of automation and data exchange in technologies, and can be a benefit for efficient management of construction and technical facilities, but requires efficient use of digital information from the beginning in early design throughout construction and operation. 

The World Tunneling Congress 2019 opened officially on Monday May 6th, with the Opening Ceremony, but thematic courses and international teams started to work May 3rd.

The official program is distinctive in the way it highlights the many connections between the world of tunnelling and the disciplines that until now have been considered unrelated to the field. A special Triple-A sessions - Archaeology, Architecture and Art are examples of such topic, and is followed up with a special visit to see the Tunnel Borbonico, the ancient underground tunnel commissioned in 1853 and just recently restored.

In March the Italian delegation invited to an Italian PIARC conference, discussing Temporary alternative measures for tunnel safety.

Society is built on standards, and standards promote innovation! When everyone in the industry uses the same starting point - a common standard - then good practice can be implemented more easily, which in turn makes it easier to build our society in a safe, sustainable and profitable way. 

Several innovative businesses are working with new better materials to provide tunnel owners with construction elements that uses materials well suited for other more demanding industries. But are we ready to challenge the traditional materials?

An important part of upgrades and rehabilitation of tunnels is to protect side area that represent a risk for collisions. The new SMA crash cushions from Automation Manufacturing Services ltd. prove that it is possible to produce space-saving solutions that are easy to install, reliable over time, maintenance friendly and provide a high degree of safety. 

By adding thermography, thermal imaging, together with 3D laser scanning and visual imaging, it is possible to detect hidden damages beyond what can been seen from on site inspections. 

Experts from businesses and public bodies from all over the world use the well-known Hagerbach Test Gallery in Switzerland to perform research, development, testing and full-scale experiments. The VersuchsStollen Hagerbach AG facilitate cooperation between companies, associations and research institutes, to improve construction, operation and safety of tunnels with a professional approach.

06 - 07 December 2017, London, Great Britain.                          

New Civil Engineer’s 11th Tunnelling Summit bring together stakeholders and decision-makers from clients, designers, contractors and their supply chain.
