| Hochtief build tunnels for XFEL research facility in Hamburg German builder Hochtief was awarded the contract to handle the largest part of the European XFEL X-ray laser project in Hamburg. As leader of a joint venture, Hochtief Construction is to realize almost all the tunnel and shaft structures for the project, with a volume of EUR 206 million. The Hochtief share of this is 50 percent. The client is the DESY (Deutsches Elektronen-Synchrotron) research center. The XFEL project is being funded by ten EU countries, Russia and China, the German government and the federal states of Hamburg and Schleswig-Holstein. The new facility, which is the only one of its kind in Europe, is due to go into operation in 2014. The Hochtief-led joint venture is to realize a widely ramified tunnel system with a total length of almost 5.8 kilometers. This will link the Hamburg district of Bahrenfeld with the municipality of Schenefeld in Schleswig-Holstein. To ensure that the facility operates perfectly, the total deviation of all the tunnel sections together must not exceed ten centimeters. Along the route of the tunnel, Hochtief and its partner will build six shaft structures and underground research facilities at depths of up to 26 meters and areas of up to 4 500 square meters. Work will begin in January and is due to be completed in April 2013. write your comments about the article :: © 2008 Construction News :: home page |
