Within the framework of the Centre for German and International Foundation Engineering Law Inc. (CBTR) conference in Vienna, the foundation engineering law prize was presented at the end of June. The...

Seen from the fire service’s point of view, the risks in tunnels mainly result from the necessary penetration depth. The expected heat load affecting fire services on the other hand is of a secondary nature. Consequently, the chances for successful deployment are largely determined by the distance between the emergency exits.

Heat in the ground can be exploited by energetically activating structures in contact with the ground, e.g. tunnels. In the course of the upgrading of the railway route from Munich to Verona, a part of a tunnel in the area of Jenbach in the Tyrol has been thermally activated in order to supply geothermal energy to the nearby utility centre.

The construction of a gas pipeline passing through a coastal nature conservation area was essential to exploit a gas field in the Atlantic. The gas is then processed in a facility on the Irish north-west coast. It was decided to thread the pipeline through the specially devised Corrib Tunnel so that the nature reserve could be underpassed without harming the environment. The tunnel was completed along with the operational gas pipeline in early 2015.

Shotcrete has developed from an auxiliary building agent to an efficient construction material. This is due to intensive development of the starting materials and processing equipment as well training...

Centralized tunnel monitoring heralds new challenges for the operating staff in the control rooms. Ongoing further development of the data acquisition and control systems installed in the tunnels leads to the amount of data received in control rooms and handled by the operators piling up. Tailor-made visualization of data by the control systems for the task in hand is an important prerequisite for dealing effectively and efficiently with a large number of monitored tunnels.
