CFF - Infrastructure Lausanne
2012 - 2015
Construction of a cut-and-cover tunnel using secant pile walls, with the concrete poured in two phases to permit continuous use of the road.
Intense three-day shutdown of the CFF line to undertake the earthworks in a top-down manner below the existing works; to complete the piled wall; to install the front wall; and to bring the tunnel into service.
