ILF has been commissioned as part of an engineering consortium (INGE Axe Bauleitung) for the construction supervision for the new Axenstrasse road project. The project is expected to run until the end of 2033.

The Axenstrasse road was built between 1861 and 1865 and is located in Central Switzerland. The road has been damaged several times by rockfalls and mudslides, which is why a new Axenstrasse road is now being built.

ILF has commenced its construction supervision work at the Gumpisch temporary bridge. The temporary bridge will be constructed in an area sensitive to rockfalls and will allow traffic to be diverted from the Axenstrasse road thus facilitating further construction works. Construction of both the major tunnel construction lots is due to start in 2025. The construction site from Ingenbohl to Gumpisch stretches over a length of approx. 8 km. In the tunnel-driving phase, up to six tunnel drives (main and counter drives) are to be supervised in parallel. Also in the construction phase for the entire project, several construction sites for lining works are to be supervised in parallel.

In order to deal with the natural hazards posing a threat to the availability of the Axenstrasse road, an early warning system has been introduced and contributes to greater safety during construction works. Work on the Gumpisch temporary bridge is taking place whilst there is ongoing traffic on the Axenstrasse road. Thanks to the good cooperation with the road operator AfBN, the client and the security firm that are helping to control the adjacent traffic, the work and traffic have to date been accident-free.
