About the Congress

Introduction to WTC2023

The Greek Tunnelling Society, organizes between 12 – 18 May 2023 the World Tunnel Congress (WTC2023) in the city of Athens. The WTC is the premier annual event of the International Tunnelling Association (ITA-AITES) and is considered as the top attended tunnelling conference in the world with the participation of more than 2000 professionals.  The congress will take place in the international conference center MEGARON which is considered as one of the finest and most technologically advanced conference venues in Europe.

The theme of WTC2023 “EXPANDING UNDERGROUND”, will focus on the Knowledge and Passion that our industry offers to Make a Positive Impact on the World. WTC 2023 in Athens, that will be carried out in hybrid mode, will highlight on the multiple advantages and solutions that underground space can provide, at the prospect of a whole new era of smart technology, where sophisticated “digital tools” change investigation, design, construction and operation methods and strategies rapidly.

The congress covers all “hot” topics of the tunnelling and underground space industry, whereas a high scientific level will be ensured as all papers, prior to publication, will be peer reviewed by highly skilled professionals and academics coming from all parts around the world. The total number of the members of the scientific committee exceeds one hundred fifty (150), while all accepted papers for publication will be made available to an open access portal via the platform of a highly esteemed international editor. Hence, the research / work / best practice / efforts of the authors participating in the WTC2023 will be freely and permanently available so anyone, anywhere, can read and build upon his / her / them work.

WTC2023 will also host a large exhibition with plenty of space, where traditionally all major international firms involved in the tunnelling industry participate.

The program of the WTC2023 will start with the training courses of ITA-TECH between 12 to 13 May 2023, whereas the main congress activities (i.e. scientific program and technical exhibition) will take place between Monday (15/5) and Wednesday (17/5). During the whole congress week, all regular annual ITA activities will be organized (i.e General Assemblies etc), along with the various meetings of the working groups and of ITA’ s committees. Last but not least, thanks to the construction activity that will take place in Athens by 2023 several technical visits will be organized providing to the delegates various alternatives to choose upon.

Athens, a vibrant modern European capital situated by the Aegean Sea, is an ideal location for international conferences. Following the unprecedented circumstances that the pandemic caused and after tolerating while within a pandemic, for almost two years, the necessary social distancing, the lockdowns and the long-lasting travel restrictions, the need to hold a conference with a physical presence has become a great desire for all of us and we look forward to this moment with great anticipation. Thus, timeless Athens sounds like the ideal conference host city and the meeting hub of the tunnelling and underground space professionals, thanks to the pleasant climate conditions during mid-May and its unique blend of history, art, culture, lifestyle and entertainment.

We strongly believe that WTC2023 held in Athens (Greece) will provide a valuable opportunity and a fertile soil for the international underground society to make a literally positive impact on the world.

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).
