| Bilfinger Berger builds tunnel for high-speed ICE rail line in Thuringia German construction giant Bilfinger Berger has been commissioned by Deutsche Bahn to lead a consortium for the construction of three tunnel structures with a total length of around 10 kilometers, part of the new high-speed ICE rail line in Thuringia. Total volume amounts to €290 million, 40% of which is accounted for by Bilfinger Berger. At the core of the project is the 7.5-kilometer long Silberberg Tunnel, the largest single investment of the 100-kilometer long new rail line section between the Bavarian town of Ebensfeld and Erfurt, the state capital of Thuringia. The tunnel's security concept includes eight emergency exits no more than 1,000 meters apart, which lead outside through a gallery running parallel to the tunnel. In addition, the joint venture led by Bilfinger Berger will build the Brandkopf and Lohmeberg Tunnels with a total length of 2.5 kilometers. The dual-track tubes will be built primarily using the drill and blast method, individual sections will be constructed using excavator driving. The drive has been designed as hard-surfaced roadway for speeds up to 300 kilometers per hour. The new Thuringia rail line is part of the German Unity Transport Project No. 8 and will significantly cut travel times between Nuremberg and Berlin. Commissioning will take place section by section in the years 2015 to 2017. write your comments about the article :: © 2009 Construction News :: home page |
