More about us


From September 2 to 8, 2022, the DFTU (Danish Society for Tunnels and Underground Works) will host the World Tunnel Congress 2022 in the Danish capital Copenhagen.

The congress, the accompanying exhibition and the annual ITA meeting will be held at the Bella Congress Center, which is ideally suited as a venue for the congress and exhibition not only because of its sufficient capacity. The congress center is also only 15 minutes from the airport and less than 10 minutes from Copenhagen city center.

As part of WTC 2022, Denmark and neighboring Scandinavian countries are taking the opportunity to showcase some of their major infrastructure and tunneling projects. New metro lines (Cityringen, Nordhavn and Sydhavn) are under construction; the experience gained in fixed transport links across the Great Belt and Øresund will benefit the Fehmarn Belt Tunnel project; and Norway, Sweden and Finland also have major new infrastructure projects in the pipeline, such as fjord crossings by means of bridges and tunnels for the Norwegian E39 coastal highway.

The annual geomechanics colloquium has developed as an important meeting point for experts in Central Europe. The event with the associated exhibition usually attracts over 800 participants annually, making it one of the largest annual events in the field of geomechanics worldwide.

The Austrian National Committee of the ITA (International Tunneling Association) organizes the Austrian Tunnel Day in conjunction with the Geomechanics Colloquium. The Tunnel Day focuses on presenting the latest state of the art of Austrian and international engineering concepts in design and construction.
Recent creative developments in design, construction, and operating methods in tunnelling are presented. The application of those new design and construction concepts will promote further innovation in future tunnelling projects.
