The STS organizes annually the Swiss Tunnel Congress at the KKL Lucerne.

During the last few years, this annual STS event has developed into the main congress for tunnelling experts in Switzerland, originally evolving from the AlpTransit congresses.

There are annually around 800 experts from 15 nations attended the high quality presentations and additionally enjoyed the traditional excursions to large construction sites within Switzerland and the surrounding area which took place.

STC development

Gradually building up on its successes, the STS is developing the Swiss Tunnel Congress and broadening the spectrum of topics, lectures and excursions, from the base tunnels to other interesting tunnelling projects in Switzerland and world wide. This broadening of the lectures will be continued. Additionally, the exhibition area will be enlarged and the STS endeavours to increase the attractiveness of the Swiss Tunnel Congress for its visitors. For the STC 2008, the newly established Advisory Board and the ST-Colloquium has been introduced.

Advisory Board

The Advisory Board provides interesting projects and highly qualified speakers from abroad, helping to maintain the high quality of lectures.

The Advisory Board consists of:

  • Gérard Seingre, Dipl. Ing., STS
  • Davide Fabbri, Dipl. Ing., STS
  • Pedro Ramírez Rodrígez, Ing., AETOS
  • Robert Galler, Univ.-Prof. Dipl.-Ing. Dr. mont., ITA Austria
  • Roland Leucker, Prof. Dr. Ing., STUVA/DAUB
  • Giuseppe Lunardi, Ing., SIG
  • Emmanuel Humbert, Ing., AFTES

Swiss Tunnel Colloquium

As of 2008, on the opening day, a half-day lecture will be introduced. This will be of a teaching with informative nature offered together with universities and industry, given the industry the opportunity to present itself.

The Swiss Tunnel Colloquium has a special topic every year.
