Models for financing, cost and risk assessment

The "Long Railway Alpine Tunnel Project Managers" group was founded in 1993 on the initiative of the SBB. Initially, the two project managers from the Mont-Cenis (now Lyon-Turin) and Gotthard Base Tunnels were involved. Later, those responsible for the Semmering, Brenner and Lötschberg Base Tunnel projects and for the Channel Tunnel were included in the group, which is now called "Project Managers Long Tunnels". The group has been meeting about twice a year for over 20 years to exchange information and experiences. The composition of this group and the valuable exchange of experience have led to cost-effective and functional solutions.
