Overall safety concepts (RABT) for 20 road tunnels in the city of Cologne

The tunnel safety department of KREBS+KIEFER Beratende Ingenieure GmbH has been commissioned to produce the overall safety concepts (RABT) for 20 road tunnels in the city of Cologne.

Be­fore the many tunnels under railway facilities were examined, the first stages of the work concentrated on the group of tunnels around Cologne Cathedral.

Here, overall safety concepts as specified by RABT were required for the tunnels under the cathedral steps and the Johannisstraße and Trankgasse roads.

The special characteristics of the structures involved as well as the interdependencies with and/or risks to neighboring facilities (the main station in Cologne) were taken into consideration in each case.

In the same way, interdependencies with other tunnels in this group (Am Domhof, Bahndammstraße and Bischofsgartenstraße) had to be considered.
