Extending the Metro Network in Copenhagen

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.


Züblin and Hochtief build Harbour Tunnel in Bremerhaven

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.


Brenner Base Tunnel: Largest Contracts awarded so far

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.

Panama City’sMetro Line 1

The Panamanian transportation system has gone through several stages of transformation in the last three years. Government efforts focused on the construction of Line 1 of Panama City’s Metro, a project that took 20 months of implementation and came into operation at the beginning of April 2014, covering a total distance of 14 km with almost 7 km running underground.


To Access the Coal:Unique TBM tacklesDecline Drives

When a location in remote Northeastern Australia near the town of Moranbah was designated as a new, “greenfield” site for a coal mine, the owner – the mining company Anglo American – was concerned about the project schedule and the necessary time to access the coal. A deep coal seam required access via decline tunnels within a quick time frame. To achieve this, the mine opted for the use of a tunnel boring machine, marking the first use of TBM technology in the Queensland coal industry.


Gotthard Base Tunnel: Control Technology

In Switzerland the Gotthard Base Tunnel is being built as part of the new rail routes crossing the Alps (NEAT). Towards this end, Siemens was commissioned to provide the tunnel control system. The technology in the Tunnel Control Centre (TCC) represents the beating heart for monitoring and controlling the electro-mechanical systems and is responsible for all operational processes. The electronic system caters for efficiency and safety in the tunnel. Thus the operator in the TCC receives a complete overview of the status of operational systems at any given time. In addition, the Maintenance Management Tool controls how maintenance operations are planned.


Axis Deviationswhen producing Diaphragm Walls

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.

Kö-Arch Tunnel in Düsseldorf completely lit by LED Technology

The Kö-Arch Tunnel in Düsseldorf is the first tunnel in Germany to be completely illuminated by LED technology. The tunnel is part of the complex “Kö-Arch” urban construction concept, which diverts traffic in the city centre underground in favour of green areas and pedestrian routes. The entire tunnelling project at Düsseldorf’s Kö-Arch is due to be completed by the end of 2015.

Underground Construction at the InnoTrans 2014 in Berlin

Within the scope of the opening press conference marking the InnoTrans 2014, the world’s largest fair for transport technology, Dr.-Ing. Roland Leucker, the STUVA CEO, emphasized that tunnels only represent a small part of the infrastructure but nonetheless a highly important one. After all, tunnels often make the efficient use of high-speed routes possible. He provided the journalists present an overview of the advantages, which result if the required infrastructure is placed underground with lucid examples for increasing the need for mobility and cutting down on travelling times.

2013 Young Scientist Prize – A Trip to Toronto

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.
