Implenia wins major contract from SBB

The IBD consortium, led by Implenia and with partners Bernasconi and De Luca, has won a major contract as part of the Ligerz-Twann double-track expansion project. The total contract value is CHF 220 million, with Implenia's share amounting to around CHF 150 million, according to the company.

The consortium will construct the 2.1 km long double-track Ligerz tunnel for SBB, of which around 1.8 km will be built by mining and around 250 m by cut-and-cover. The project also includes four escape tunnels, a 114 m long viaduct for the N5 highway exit and various additional structures. With the double-track expansion, SBB wants to eliminate the last bottleneck on the Jura line between Lausanne and Biel. (ah)
