Underground – the way to the future was the motto of the World Tunnel Congress 2013. The World Tunnel Congress (WTC) and the 39th General Assembly of the International Tunnelling and Underground Space Association (ITA) were held between 31 May 2013 and 7 June 2013 in Geneva, Switzerland.
The use of underground space has gained importance during the last years due to the tremendous global urbanization, the high demand on transportation capacities and energy production. All this result in a wider range of use of underground space: besides the traditional road, railway, metro and utility tunnels, more and more other functionalities of modern life are placed under ground in order to free the surface for other uses.
The 300 papers of the WTC 2013 cover important aspects of modern underground infrastructures: Development and use of underground space; project planning and implementation (construction management, risk control, cost estimation and scheduling, contracting practices); design and analysis methods and considerations; construction technology developments; tunnel operation (safety, maintenance, rehabilitation and repair); case histories (learning from failures, long deep tunnels, underground construction for hydropower).
Underground – the way to the future will be invaluable to specialists, contractors and design engineers in underground planning, construction and tunnelling worldwide, and to academics interested in underground and geotechnical engineering.

The World Tunnel Congress (WTC) and the 39th General Assembly of the International Tunnelling and
Underground Space Association (ITA) were held between 31. May 2013 and 7. June 2013 in Geneva,
Switzerland.
The Swiss Tunnelling Society was honored and proud to host this outstanding event of the international
underground space community.
Hundreds of experts, consultants and designers, contractors, clients, suppliers, manufacturers and specialists
gathered in Geneva with the motto ‘Underground – the way to the future’ to present the latest developments,
discuss interesting case studies and exchange information about technological trends and challenges of the
future in underground construction.
The call for papers turned out to be very successful. About 300 papers were accepted out of which 100 were
selected for oral presentations in a series of technical sessions covering all aspects of modern underground
infrastructures: from the development of the underground space over design and construction aspects to operation
and decommissioning of underground facilities. The papers also address new challenges of underground
space development which reflect the increasing awareness the underground space has gained during the last
years. Various factors have led to this increasing awareness; the tremendous global urbanization is just one
among many others. This also documents the important role the underground space will play in the years to
come in order to cope with the growing demand for mobility and quality of life. The underground space will
definitely be a part of the way to the future.
The increasing importance of the underground space also results in its wider range of use: besides the
traditional road, railway, metro and utility tunnels more and more other tasks of modern life are put under ground
in order to free the surface for other uses. This involves various new challenges, which were taken up at the
WTCin Geneva. For instance the ITA COSUF (ITA Committee on Operational Safety of Underground Facilities),
whose annual workshop was presenting safety and security aspects of underground facilities, discussed this
issue under the title: Complex Underground Multipurpose Facilities – Safety Challenges and Solutions.
At the WTC 2013 in Geneva, a larger auditorium gained insight into the newly established ITA tech (ITA
Committee on technologies) for the first time at the World Tunnel Congress.
In the ITA tech Innovation Session the guidelines, recommendations and state of the art reports which have
been elaborated by the various Activity Groups were presented. They showed clearly how this Committee
contributes to the introduction of innovative methods, processes and materials for underground construction.
Special emphasis to the increasing and innovative use of the underground space was also given in the
welcome speech of the Swiss Minister of Environment, Traffic, Energy and Communication during the Opening
Ceremony. It highlighted that Switzerland has been striving for a sustainable and environmental friendly traffic
and energy policy and that, during the past decades, the underground facilities have played an important
role and will also continue to be a key factor for the implementation of this policy. The world’s longest railway
tunnel, the Gotthard Base Tunnel which will open in 2016, is merely the newest and probably most outstanding
example in this respect. The Swiss Session dedicated a full half day session to show various aspects and
innovative solutions of this project to the international underground construction community.
The keynote lectures addressed other aspects concerning the use of the underground space and could
therefore round the entire topic off in a very coherent manner.
This little excerpt of the numerous sessions illustrates the variability of topics which created the lively atmosphere
at the WTC 2013 in Geneva. The extended abstracts in this booklet and the proceedings of all papers
in electronic form on the USB memory card do not only contain valuable information but also show the wide
variety of the presented contents.
After several days filled with technical sessions, the WTC 2013 was rounded off in a festive atmosphere
with a joint banquet on old steam boats on the lake of Geneva and with various interesting excursions to
underground construction sites in Switzerland.
Very many people have contributed to the success and the unique atmosphere of the WTC 2013 in Geneva.
The Swiss Tunnelling Society would like to express its gratitude and thank those who have contributed to the
successful accomplishment of the event to a large extent, either in front of behind the scenes. The Swiss
Tunnelling Society would like to express special thanks particularly to all those persons not mentioned here as well as to the organizing committee of the WTC 2013, in particular G Anagnostou, H Ehrbar and E Pimentel
(technical sessions and proceedings), M Bosshard (Swiss session), L Gruber (sponsoring and exhibition),
X Roulet (finance), M Neuenschwander (excursions) and their collaborators, the WTC secretariat namely C
Ackermann and C Kurath, all the chairpersons, lecturers, excursion guides, volunteers etc.
The Swiss Tunnelling Society also thanks the large number of sponsors for their strong and decisive support
of the WTC 2013. Without them the WTC 2013 would not have been possible
