September 12, 2024: we celebrate the long-awaited breakthrough of the first tube of Semmering Base Tunnel. This means that Mürzzuschlag and Gloggnitz are connected for the first time through the 27.3km long tunnel tube - a historic moment! 

We are proud that we have been able to participate in this once-in-a-century project since 2008. It is a great honor for us to bring our skills into the route selection phase and the preliminary design. We are also happy that we can make a contribution with the tender and implementation planning as well as with our powerful on-site team (site management and geotechnics).
