  • Return:      17:30 - 18:00


  • Restricted participation!
  • Please take care that we are entering a construction site – hence dirt cannot be avoided.
  • Safety equipment can be provided, however if possible please bring your own personal protection equipment (PPE) with you.


1)  Research@ZaB  - Zentrum am Berg

The Res@ZaB is an Austrian centre for research, development and testing, with special focus on tunnel safety while excavation and operation. The technical visit starts with a presentation of the tunnel-system and current research activities. Since ZaB now is in its commissioning phase, visitors have the possibility to see the full ventilation installation, which includes jet-fans, axial fans, smoke extraction dampers and cross-passage ventilation. After lunch, visitors are welcome to be active part at a training-session of the fire brigade Linz and at an evacuation drill/simulation under limited viewing conditions. The final showdown will be a fire-test of the fire brigade Linz. Because ZaB is still a construction site, vistors are asked to take (if available) their personal protection equipment (helmet, jacket, shoes) with them. A certain amount of helmets and jackets will be available at ZaB.

2)  Semmering Base Tunnel

The technical visit allows a very close look to a huge underground construction site with various parts of underground construction facilities like tunnel boring machine, explosive propulsion, ventilation etc. We will reach these facilities via a 400m high ventilation shaft at Fröschnitzgraben.
