Bilfinger Berger Magazine 2/2009

To serve the new 100 kilometer high-speed line being built between Ebensfeld and Erfurt, Bilfinger Berger is building three tunnels with a total length of around 10 kilometers.

Total volume for the pro ject amounts to €290 million, of which 40 percent is accounted for by Bilfinger Berger. The key feature of the route is the 7.5 kilometer Silberberg tunnel. Bilfinger Berger will also construct the shorter Brandkopf and Lohmeberg tunnels. The twin-track tubes will be excavated pri marily through the drill and blast method. The high-speed rail route is part of the German Unity No. 8 transport project due to enter serv - ice somewhere between 2015 and 2017.
