Swiss Tunnel Day in Biel, Switzerland

The Swiss Tunnel Day 2025 (STDay 2025) brings fresh impulses for the underground construction industry! With a new location in Biel and a revised structure, the annual event is becoming more compact and attractive. The focus is on Swiss underground construction projects.

This change is an opportunity! STDay remains the central meeting place for Swiss tunnel builders, where knowledge is exchanged and new ideas are generated. In addition to technical presentations and discussions, the introductory lecture by the new ETH professor of underground construction, Prof. Linard Cantieni, will provide valuable food for thought for our future and that of our young talent.

We look forward to interesting encounters and lectures.
