From May 22 –28 2015 the host of the World Tunnel Congress 2015, the Croatian Association for Underground Construction – ITA Croatia, invites the international tunnelling community to Dubrovnik,...
Work on the tubes of the Brenner Base Tunnel, one of the largest underground infrastructure works in the world, is in full swing on different fronts. Excavation of the new Tulfes-Pfons section...
Terratec has announced a new Tunnel Boring Machine delivery for Istanbul Metro in Turkey at the end of August after the successful performance of the workshop testing. The official ceremony was held...
The Brenner Basistunnel Gesellschaft (BBT SE) has commissioned a JV comprising Strabag Austria and the Italian Salini Impreglio Company to build the biggest contract section awarded so far, the Tulfes-Pfons section including 38 km of tunnel. The amount of investment involved is some 380 million euros. Driving operations were embarked on on September 19, 2014 with the construction period estimated to last roughly 4 ½ years.
BIS Bremerhavener Gesellschaft für Investitionsförderung und Stadtentwicklung mbH has commissioned a joint venture (JV), consisting of Ed. Züblin AG (technical leader/JV share 37 %), Hochtief Solutions AG (commercial leader/JV share 33 %) and Züblin Spezialtiefbau GmbH (JV share 30 %), to build the Cherbourger Straße harbour tunnel in Bremerhaven. The tunnel is to run from East to West and will be located south of Cherbourger Straße. It will serve as an efficient road link, connecting the international port and business parks located close to the port with the motorway A 27.
After commissioning two new Metro stations in Nuremberg, Germany, in mid-2008, two further construction sections for an extension were originally planned. One of these two sections – BBA 2.1 from...
Extending the Copenhagen Metro network constitutes part of the Danish capital’s City Ring. Towards this end, two tunnels – 1800 and 1600 m in length – are to be driven one after the other by mechanized means. Furthermore apart from the Nordhavn Metro stop a small tunnel will be driven towards the neighbouring tram line station.

Within the scope of the 2013 STUVA Conference, Mag. (FH) Susanne Fehleisen, ÖBB Infrastruktur AG, came out on top at the “Young Forum” competition winning the prize for her contribution “Koralm Tunnel: Applying the Rescue and Fire Protection Concept for complex Underground Construction Sites taking the Example of the Main Contract Section”. The prize involved a trip to Toronto to a rather unique tunnelling site.
At various construction sites the production accuracy regarding the axis deviations of diaphragm wall lamellae was investigated. After evaluating different series of measurements the normal distribution in accordance with Gauß was established as the suitable mathematical method for describing the frequency distribution. Under similar general conditions the determined parameters can provide the possibility for working out the anticipated axis deviations prior to executing a construction scheme.
