The new Semmering base tunnel is an important section within a high-speed route of the Trans-European Network (TEN).
The challenges of this tunnel project are the water bearing sections with large amounts of water and high water pressures of the carbonat rock areas Otterstock and Grassberg (300 l/s, 300 m water head) as well as squeezing sections of fault zones, such as the Grassberg-Schlagl fault system.
- Alignment development in the alignment selection process
- Collaboration in the preparation of the documents for the environmental impact assessment and for obtaining construction permission
- Forecast of the production costs in the respective project phases
