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 Kvitsøy contract is described as the most technically challenging of the three Rogfast contracts to be announced. There will be a 20.6 km tunnel, 4.5 km of road and five new bridges on Kvitsoy, and in addition two 250 meters ventilation shafts with a diameter of ten meters drilled down to bthe main tunnel under Kvitsoy (illustration: Norconsult/ Statens vegvesen).
A new version of the DG QRAM software (Quantitative Risk Assessment Model for the Transport of Dangerous Goods in Road Tunnels) has just been published. This PIARC software is currently under development and a new update has been released.
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 Ryfylket tunnel will be completed in 2019 and will provide connection between small communities and the large city municipality of Stavanger, Norway. A large population travel daily by ferry, and will in the future travel through this 50 km long tunnel project, consisting of three main tunnels.
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.
This conference focused on tunnels as a vital links in any transportation network. Short periods of closure for maintenance or repairs always generate nuisance. Long periods of closure for renovations will logically lead to severe congestions. For too long, the tunnel community has accepted this nuisance and chaos as a natural side effect of tunnel operations. Should we accept this?
