Lausanne - Switzerland


Transportation Department, Canton of Vaud


Study and monitoring of realization of a section of the Lausanne metro


Lot A, which SGI had the charge, is a plot of 1.5 km underground about 6 km of the line.
It consists of:

  • three underground stations (SBB stations, Flon and Ripon)
  • Two new tunnels of 300 m each and
  • two tunnels of 250 m to be rehabilitated.

The subway is an underground automatic tire type VAL. The tunnels will have a template for two lanes. SGI was in charge of all studies from research technical solutions to monitor the achievement of which one of the constraints was the presence of buildings nearby.
