Welcome letter to sponsors

We are very pleased to announce the sponsorship and exhibition opportunities for the World Tunneling Congress of 2023, which will be held in our beautiful and historic city of Athens, between 12-18 May 2023. The venue is the impressive Megaron Athens International Conference Center (MAICC), located right in the heart of the city, easily accessible by direct metro line from the Athens International Airport, with major sights as well as plenty of hotels of various categories within walking distance (please visit the hospitality area of this website to choose and book your team’s accommodation).

With more than 12.000 sq m of foyer, mostly full of daylight and plenty of outer space, the MAICC is considered an exceptional place for exhibiting and networking. Looking ahead to 2023, the probability of a non-COVID on-site event is almost certain, and the opportunity of a social contact return is in view.

Keeping up to date with technology and sustainability though, a virtual part of the Congress has been designed to upgrade and facilitate the sponsors and participants that would not be able to travel to our city for the Congress.. In this way, both sponsors and exhibitors will have the privilege to get promoted, not only on-site, but also virtually.

The Greek Tunneling Society, the host Society, along with a distinguished international scientific committee, is carefully designing a scientific program with innovative ideas and interactive sessions, to provide an ideal opportunity to showcase recent trends and developments of the underground space industry.

Professor Marc Panet

The 12th Muir Wood lecture will be delivered by Professor Marc Panet during the WTC2023 in Athens. His nomination being a Muir Wood lecturer was proposed by the French Tunnelling & Underground Space Association (AFTES) as per ITA’s Statues and By-laws.

Marc Panet graduated in Civil Engineering at the École des Mines de Paris and obtained a Master degree at the University of California at Berkeley. He started his career in 1965 at the Laboratoire Central des Ponts et Chaussées, in Paris, where he was a Research Engineer, Head of the Geotechnical Department and Technical Director. In 1982 he joined the SHP Group, in Paris, as Scientific Director. From 1984 to 1996 he was the President and CEO of SIMECSOL; and from 1996 to 2000 President and CEO of FC International SA. Since then he has been working as a consultant. He taught at the École Nationale des Ponts et Chaussées, at the École des Mines and at the École Centrale des Arts et Manufactures, in Paris.

Marc has been in charge of numerous studies in geotechnical engineering for underground works, highways, bridges, and natural hazards. Among the main projects are: the Mont Blanc Tunnel (11.6km), the Frejus Road Tunnel (12.9 km), the Large Electron–Positron Collider (CERN in Geneva), the Channel Tunnel (from 1967 to the end of the construction), the Millau Bridge, the Loetschberg Base Tunnel (43 km), subways in Paris, Rennes, Caracas, Athens and Algiers, the slides of the city of Constantine (Algeria), the project of the suspended bridge on the Straits of Messina (Italy) and the project of the cable-stayed bridge on the Golden Horn (Turkey). He is presently involved in a large number of geotechnical projects.

He is the author of a large number of publications in professional journals and international conferences and of the well-known book “Calculation of tunnels using the convergence-confinement method”.

Marc Panet is a Honorary Member of the French Academy of Technology, Knight of the National Order of Merit and Knight of the Order of Academic Palms.
