The works on the third and last tunnel contract, "Tunnel Grautschenhof", started in May. At first, the miners will have to conduct the preparatory work on the 100m long shafts between Spital am Semmering and Mürzzuschlag in Styria. Both tubes will be excavated using the drill and blast and the mechanical excavation method between Gloggnitz and Mürzzuschlag.
The first preparatory works, such as the set up of the construction site cabins and the noise protection barriers as well as the earthworks, have started on the construction site in Grautschenhof. The excavation works on both of the 100m long shafts will begin in fall of 2016. Construction work will be completed in 2026, enabling rail passengers to travel in less than two hours from Vienna to Graz.
