BAM wins contract for Swiss railway tunnel

Bunnik, the Netherlands, 27 January 2015 – Wayss & Freytag Ingenieurbau, the German tunnel specialist of Royal BAM Group, has won a joint venture contract for the construction of the 2.6 kilometer long Eppenberg Tunnel in Switzerland. The joint venture partner is the Swiss contractor Marti. The share of Wayss & Freytag Ingenieurbau is over €35 million. The two-lane tunnel is an important element in the Olten-Aarau railway (halfway between Basel and Zurich), which is currently being widened to four tracks by the Swiss government and the Swiss railway company SBB.

For the construction of the Eppenberg Tunnel the joint venture will use a mix-shield tunnel boring machine, which is designed to tunnel through both hard rock and wet soil. The tunnel machine has an outer diameter of approximately 12.80 metres.

The project also includes the construction of three emergency and escape tunnels, five shafts for technical areas and niches for M & E installations. The joint venture expects to complete the tunnel in August 2019.
