Preface
The Croatian Association for
Tunnels and Underground Structures ITA Croatia and International Tunnelling and
Underground Space Association ITA-AITES organize this year together a world
tunnel congress 2015. The congress is organized with the title: “SEE Tunnel:
Promoting Tunnelling in SEE Region” to develop the use of underground space in
the South-East Europe region. Submitted articles are grouped within 13
different themes covering most of important topics presenting nowadays
tunnelling experiences. Themes and topics presented herewith are recent
international state-of-the-art practice applicable in other countries and in
similar geological formations.
Session 1: “Planning and Designing Tunnels and Underground Structures”
The most articles of entire
congress submissions are in this session and presenting leading projects
worldwide within different project development phases.
Session 2: “Fire Safety of Tunnels and Underground Structures”
Presentation of active and
passive fire safety measures and actions taken or planned for tunnels and
underground structures in use or design and planning project development
phases.
Session 3: “Mechanized Tunnelling in Development and Use”
Numerous submissions about
different projects worldwide, new experiences and developments with materials
in use and least experiences with new type of machines.
Session 4: “Operation and Maintenance of Tunnels and Underground
Structures”
Presented are experiences from
numerous projects worldwide as the number of underground structures is raising
and as well the required need for their maintenance.
Session 5: “Developments in use of Underground Space: Case Studies”
There are numerous examples of
different projects using underground space in completely new, modern interesting way. Case studies about recent applications
are showing new approaches and possibilities of underground space use.
Session 6: “Cost Optimization and Financing of Underground Structures”
Tunnels are known as most
expensive civil engineering structures but at the same time are bringing
different benefits that are not included in direct construction cost
estimations. Some of the examples are presented as well as cost-overruns.
Session 7: “Immersed and Floating Tunnelling”
Application of different crossing
locations are presented with specific problems and pertinent solutions, first
ideas for the application of IMT technologies on new markets with no previous
experience are indicated.
Session 8: “Intelligent Systems, Mechatronics and Robotics in
Tunnelling”
Robotics and use of mechatronics
technologies is coming more and more on markets and on to applications on
underground projects. More and more on machine prototypes are presented and
first experiences as well.
Session 9: “Conventional Tunnelling Methods in Development and Use”
Different Conventional Tunneling
methods are presented and compared, complicated and special construction
solutions are discussed, new conventional methods are presented for the first
time over the first experiences.
Session 10: “Urban Planning and Using of Underground Space”
How to start with the use of
underground space and how to include underground structures in existing
environment and surrounding is the work
of urban planners specialized for underground space: some ideas and
applications are showing recent developments.
Session 11: “SEE Session : Soft Ground Urban Tunnelling / Rock
Tunnelling in Karst”
Session is dedicated to applications
in SEE region and open to all participant with themes that could contribute to
application in mentioned formations with existing or new ideas bit as well with
experiences from previous projects in similar conditions collected around the
world.
Session 12: “ Risk Analyses and Techniques for Underground Structures”
Risk analysis is the part of
design management of underground structure today: whether regarding design,
construction, cost or maintenance risk. Case studies and methodologies are presented
within the session.
Session 13: “Equipment of Tunnels and Underground Structures”
Equipment as the part of the
construction technology is presented as well as equipment of tunnels that
enable full tunnel usage and services.

Dear
Colleagues and Friends
May
2015 has come and we are now gathering
again for the World Tunnel Conference
this year in beautiful Dubrovnik in Croatia to hold the ITA 41st General
Assembly and WTC2015. This year’s topic is “Promoting Tunnelling in South East Europe“ and gathering the whole
ITA family on the Balkan Peninsula will definitely bring a boost of tunnel
knowledge and technology to the region.
We
see an increasing need for tunnels and underground space not just in South East
Europe but all around the world. Wherever I look around the world, there is an
increased need for new tunnels and use of the underground space. Tunnels and
the use of underground space help our cities to become resilient by
transforming surface problems to underground solutions and there by improving
living conditions for the citizens by reducing congestion, reducing air
pollution and noise and vibrations impacts. We, as tunnellers are also helping
our citizens to provide drinking water and clean surface water by providing
tunnels for drainage, food control and sewer systems. With the increased growth
in the world’s population and urbanisation the need for use of tunnels and
undergroundspace will continue to expand. ITA has performed a survey of the
development in the global tunnel market. Over a period of 10 years the
tunnelling market has shown a steady growth in Europe, North and South America
and Australia with a global growth over 5% per yaar during the Iast decade. The
major growth has taken place in Asia where the market has increased by
approximately 15 times over a 10 year period. New market has developed
particular in the Middle East where we now see a huge activity in the
tunnelling industry where there were hardly any market 10 years ago.
We
therefore see a bright future ahead of us and we want ITA to play an important
role in this. For that purpose we have launched the ITA Strategic Plan
2013-2016 which was accepted by the
General Assembly in Iguassu last year. One of the initiatives we took was to
initiate an ITA Young Members goup, in order to attract young engineers and
scientists to our Association and Industry. With the increased growth we see
ahead it is important that we are able to boost our human resources and know
how in order to respond to our societies increased demand for the use of he
underground. I am pleased that the ITA Young Member group is now very active
and will meet in Dubrovnik.
In
Dubrovnik, we will hear about all the latest development in technology and
human resources as lessons learnt from
projects all around the world. We will meet to hear the latest update, to meet
good fiends and to network exchanging knowledgeand increasing our business
opportunities. Our working groups and committees will issue their latest
reports and will meet actively to progress the works.
I
wish you all successful conference and hope you will also get a flair of the
Croatian lifestyle and culture along the Adriatic Sea.
Welcome
to Dubrovnik.

Dear Colleagues,
It is our honour to be the host
country for the organisation and preparation of the World Tunnel Congress 2015.
At the same time it is our responsibility and duty to provide you the best possible
conditions and services for your participation and networking that is highly
appreciated on the occasion of the congress. We hope to be able to answer your
requirements and expectations and we are looking forward to see you in
Dubrovnik at the end of May 2015.
Tunnelling in South-East Europe has a long tradition
coming from mining but during the last century the range of mining has
decreased seriously. Underground works have been performed in last few decades
as tunnelling works on transport infrastructure lines and hydro projects
mostly. At the same time most of South-East Europe did not develop the use of
underground space in urban areas: there is no subway or underground road or pedestrian systems in cities of Balkan
Peninsula. This is one speciality that at the same time opens opportunities for
future investors, clients and contractors.
However, developing one
underground Project is not an easy task: it needs knowledge about planning,
design, construction, supervision, equipment, financing and maintenance of
underground structures.
This congress should be one
important step and future milestone in providing missing knowledge about the
use of underground space to countries of South-East Europe but as well to all
other interested parties or regions where such development is missing as well.
It should be the networking place opening contacts and possibilities over
business forum core that is the part of the congress.
Welcome to Dubrovnik, the hearth
of South-East Europe, the place of your future use underground space.
