Implenia is leading the construction of the Ligerz Tunnel
Die SBB hat der Arbeitsgemeinschaft IBD den Auftrag für den Bau des Tunnels Ligerz erteilt. Die Federführung innerhalb der Arbeitsgemeinschaft obliegt Implenia. Die Bau- und Immobilienfirma hat einen Anteil von 150 Millionen am Auftragsvolumen von 220 Millionen Franken.
The IBD consortium has been awarded the contract by SBB to build the Ligerz tunnel, Implenia announced in a press release. The construction and real estate company from Opfikon is the leader of the IBD consortium. In addition to Implenia, the consortium includes the construction companies Bernasconi from Luterbach SO and De Luca from Biel BE.
The contract includes the construction of a 2.1-kilometre-long double-track tunnel with four escape tunnels and a 114-metre-long viaduct for the N5 motorway exit, as well as various additional structures. The contract is worth a total of 220 million Swiss francs. Around CHF 150 million of this is Implenia’s share.
The contract is Lot 2 of the Ligerz-Twann double-track extension, which is intended to eliminate the rail bottleneck on the Jura river line between Lausanne and Biel. The Zurich-based construction and real estate company is deploying its experts from the fields of civil, tunnelling, special civil engineering, structural engineering, railway engineering and maritime work for the project. “We are looking forward to executing this large and complex railway infrastructure project together with our ARGE partners and to once again demonstrating our many years of experience and expertise in this field,” Christian Späth, Head Division Civil Engineering at Implenia, is quoted as saying in the press release. The location of the tunnel in protected areas is described there as a major challenge for implementation.
