An update about the securing of a contract – mentioned on week38/22 -  for the doubling of track work for the Gleresse-Douanne section, Lot 2, Ligerz tunnel, railway line n. 210 Ligerz-Twann.  SBB has now assigned the EUR229.48 million (CHF220 million) contract for lot 2 Tunnel Ligerz  to joint venture IBD, consisting of Implenia (lead, 68.18%), Bernasconi and De Luca.   The contract comprises of the 2.1 km long double-track tunnel, of which around 1,850 m will be constructed by mining and around 250 m by cut-and-cover, including concrete lining and railway technology. In addition, four escape tunnels, a 114 m long viaduct for the exit of highway N5 and various additional structures are being built. The excavated material will be transported by ship and the existing railway line will be dismantled and redesigned.   The aim of the project is to eliminate the last railway bottleneck on the “Jurafuss” line between Lausanne and Biel. Due to the prevailing narrow space conditions between the lake and the slope, where the N5 national road and the cantonal road also run, a new double-track tunnel will be built.
