STUVA News

The 2009 STUVA Conference held in Hamburg from December 1st to 3rd, bore the motto “Tunnels – Key to Sustainable Mobility”. This motto was impressively underlined in Hamburg. After all Germany’s second largest metropolis continues to be growing constantly. As the second largest container port in Europe and the world’s third largest location for civil aircraft construction Hamburg represents an outstanding hub for logistics and transportation. Such expansion is impossible without safeguarding mobility.
Consequently in 2009 more than 1,500 tunnellers from 28 nations turned up for one of the world’s biggest events for underground construction in order to exchange experiences, consolidate new contacts and rekindle existing ones.
The conference was opened by Professor Martin Ziegler, the chairman of the STUVA Inc. The participants were welcomed on behalf of the host city Hamburg by Senator Dr. Michael Freytag, the chairman of the supervisory board of the HafenCity Hamburg GmbH and chairman of the supervisory board of the Ham-burger Hochbahn AG (Fig. 1).
The series of lectures began in a very unusual and highly entertaining manner with the first keynote lecture presented by Prof. Hartwig Beiche, which reflected tunnels in conjunction with culture. In the second keynote address Ministerialrat Dipl.-Ing. Joachim Naumann reported on current developments in road tunnelling as well as findings in retrofitting tunnels. The following block of lectures
provided an overview of outstanding major projects in Scandinavia. This year attention was focused on this region. First of all it is close in geographical terms to Hamburg in the north of Germany. Secondly remarkable tunnel projects are being undertaken at present and in the near future in this part of Europe.
At this year’s conference the topic of safety in tunnelling was accorded especially wide scope triggered by national and international events, as particularly the collapse of Cologne’s Historic City Archives during the construction of the North-South Urban Light Railway provoked major uncertainty in conjunction with underground construction among the general public. The STUVA as one of the main organisations involved in underground construction in this connection provided a paper on safety and risks in tunnelling in the form of an interdisciplinary analysis and showed that tunnelling in general and especially in inner urban areas does not conceal incalculable risks providing certain rules are observed. Walter Reinarz, KVB board member presented the consequences of the accident on behalf of the Kölner Verkehrs-Betriebe AG.
A further group of lectures devoted itself to the important subject of safety, with emphasis accorded tunnel operation. In this connection the focus was particularly on fire in tunnels, which continues to represent one of the major hazards. Apart from combating fire, providing information to users and their evacuation were also dealt with.
On this occasion as well a separate block examined legal and insurance issues. Even although these topics are often to some extent neglected by technically-minded engineers, it is frequently these issues that decide whether a project can become an economic success. As a result practice was reflected in the lecture programme. It was also shown that contractual partners must deal fairly with one another to ensure that such a sophisticated technical task as the building of a tunnel can be executed successfully and above all safety.
The series of lectures was rounded off by a block dealing with underground construction in the Hamburg area.
The 2-day exhibition that accompanied the conference (Fig. 2) in direct relation with the lecture programme occupied a net stand space of some 2,000 m² from 6,000 m² hall area. Here 128 German and foreign companies involved in execution, subcontracting, planning and consulting presented their products and performances in the field of foundation engineering and tunnelling to a highly-qualified public.
The excursions on Day 3 rounded of the event and provided opportunities for consolidating an exchange of views and experience in a tried and tested manner. Conference participants were invited to join the excursions to the HafenCity construction site, the new control centre in the Hochbahnhaus, the 4th Elbe Tunnel Tube, the DESY technical facilities or the Airbus factory at Finkenwerder.
We should like to thank the City of Hamburg for its hospitality and the various offices involved for their collegial support in organising the excursions.

STUVA Prize 2009
Every two years the Research Association for Underground Transportation Facilities Inc. (STUVA) awards the STUVA Prize for outstanding performances and innovations in the field of underground construction on the occasion of the STUVA Conference. Personalities as well as future-oriented projects can be honoured by this prize.
This year the jury awarded the STUVA Prize 2009 to Prof. Dr.-Ing. E. h. Heinz Duddeck in appreciation of and as a tribute to his lifework in tunnelling (Fig. 3). Until becoming emeritus professor in 1996 he held the chair and was director of the Institute for Statics at Brunswick Technical University.
Professor Duddeck greatly influenced tunnelling over the years. Originally concentrating on structural engineering and bridge-building his sphere of activities extended to embrace underground construction by dint of his thirst for knowledge in trying to get to the bottom of things. He first came in contact with tunnelling through compiling statics for a part of the Hamburg metro system. Towards this end he came up with a new analytical method for the bedded circular ring. His related article jointly published with Schulze on “Stresses in shield-driven Tunnels” has become a standard publication. He questioned many of the methods of calculation that were applied at the time. He came to initiate studies devoted to “tunnelling” with the German Research Foundation (DFG) and became a member of the senate as well as the main committee of this body. From then on he focused on tunnelling for almost three decades (1966 till 1996), which was also reflected in his setting up a consultancy office. The list of his test and consulting activities includes practically all prestigious German projects: Hamburg Elbe Tunnel 1966, Gelsenkirchen urban railway tunnel (mining problems), tunnels for the new DB German Rail route between Hanover and Würzburg (18 individual projects), Ems Tunnel Leer, excavation pit and tunnel at the Potsdamer Platz in Berlin, 4th Elbe Tunnel Tube, Weser Tunnel and BEWAG Tunnel Berlin. Some 300 publications and around 250 papers testify to his commitment.
Proceedings
The proceedings – Volume 43 in the STUVA series “Research + Practice, Underground Transportation and underground Construction” – with the full versions of all papers (either in their German or English original and abstracts in the other language) once again appeared to coincide with the conference. It was presented to all the participants.

Honorary Members
The general assembly of the Research Association for Under-ground Transportation Facilities Inc. (STUVA) decided to appoint Prof. Manfred Bandmann to become an honorary member of the association. This appointment expresses gratitude for his many successful years of activity on behalf of the STUVA especially through his involvement on the Scientific Advisory Council and the board from 2001 till 2009.
Prof. Bandmann concentrated his endeavours first and foremost on industrial safety requirements. He initiated many current research projects relating to this field, which were executed by the STUVA with the support of the BG Bau.
Prof. Bandmann also actively fostered the work of STUVA through worldwide involvement in the International Tunnelling and Underground Space Association (ITA) as well as a number of major EU projects. Thanks to his activities he has assured that industrial safety enjoys the prominent position it deserves in underground construction thus contributing to protecting the lives and health of the labour force. He has disseminated the findings he obtained in numerous lectures at STUVA conferences and ITA congresses as well as in brochures and other publications thus ensuring their translation into tunnelling practice.
Apart from expressing its gratitude the general assembly also hopes to be able to welcome Prof. Bandmann often among its ranks in future as well. It wishes him health, personal fortune and all the best for the years ahead.

Jubilee Event
50 Years of the STUVA Inc. 1960 to 2010 – The Past meets the Future
Following decades of successful work on behalf of underground construction and public transportation the STUVA celebrates its 50th anniversary in 2010.
The jubilee conference will be held in the Tonhalle in Düsseldorf on June 17th and 18th, 2010. With this event the STUVA will be returning to its roots for STUVA’s story began on June 15th, 1960 when the association’s name was entered into the register of the municipal court in Düsseldorf. It will be a time for celebrations as well as deliberations after all it will not simply be a “normal” STUVA Conference.
The jubilee gathering will be divided up into the “Young Forum” and the three-part festive ceremony:
At the “Young Forum” up-and-coming tunnellers will communicate something of the fascination exerted by tunnelling within the framework of a competition at which papers will be presented. The first part of the ceremony will be devoted to the “Future of Under-ground Construction” taking the entire spectrum of important spheres of influence into consideration.
During the second part, which will be related more to the STUVA itself, conclusions from STUVA’s past will be drawn and at the same time the link with the important theme the future of energy provided.
The final part of the event will be devoted to the “Present” and will examine in detail the largest construction project involving underground rail construction in Düsseldorf, the Wehrhahn Line.
The gala evening on the first day of the event is mainly designed to serve personal encounters and look back at the long and eventful 50 years of STUVA.
The call for papers for the “Young Forum” addressed to STUVA members resulted in a highly pleasing response so that a large selection of topical and interesting themes is available. At the same time high-category speakers will be available for the other sectors of the event. Through this selection of topics the STUVA once more wishes to emphasis its reputation for always being “abreast with the future”.
