Abstract

With the start of construction on the third tunnelling contract, work has now started on all sections of the Semmering Base Tunnel. The Tunnel Grautschenhof contract is a challenging construction project with numerous unusual problems. Complex ground conditions make extensive grouting necessary. Numerous constraints above-ground, like high-pressure gas pipelines require monitoring and protection measures. Since the start in May 2016, two shafts, the first of three caverns and the first metres of the running tunnels have already been driven. In parallel to this, the works above ground to create two site facilities areas are now largely complete.
