Venue Finlandia Hall
Helsinki‘s famous congress and concert palace, Finlandia Hall, was designed by the world renown architect Alvar Aalto. Since opening in 1971, Finlandia Hall has hosted numerous international meetings of worldwide importance, e.g. the Conference on Security and Co operation in Europe. During the Finnish Presidencies of the European Union in 1999 and 2006, Finlandia Hall was the scene for many EU summits (Fig. 1).
Technical excursions during the congress
There will be several technical excursions during the congress. It is possible to take part in from 1 to 3 excursions. Excursions will be arranged on Monday and Tuesday afternoon and Thursday morning.
1 Energy and multi-utility tunnel network of Helsinki
Beneath Helsinki lie more than 40 km of Helsinki Energy‘s multi-utility and energy tunnels, which contain district heating and cooling pipelines, 110 kV cables, medium-voltage cables and optical data transfer cables, as well as the main pipelines of Helsinki Water.
2 Itäkeskus underground swimming centre
The underground swimming centre was carved into bedrock in 1993. The spa-type underground space contains a 50 m swimming pool, whirlpool baths, saunas, a gym, etc. The facility can be converted into a shelter for 3,800 persons.
3 Viikinmäki underground wastewater treatment plant
HSY Water has centralised all of Helsinki‘s wastewater treatment operations into the Viikinmäki wastewater treatment plant. The total volume of excavated rock was 1.2 Mio. m3. The first phase (1 Mio. m3) was excavated in 1988 to 1991 and the second phase (200,000 m3) in 2000 to 2001.
4 West Metro Project
13.9 km long twin tunnel and 7 new stations. Construction started in late 2009. The westbound metro line will be owned by the cities of Helsinki and Espoo.

2.5 km service tunnel across the city, from east to west, under the historical centre of Helsinki. Construction was finished in 2010. The tunnel will be used to service shops, restaurants, offices and hotels in the area.
6 Underground coal storage and district cooling
Helsinki’s Energy underground coal storage facility in Salmisaari was built in 2001 to 2003. The project also included an underground district cooling centre, a power station and 3.5 km of tunnels. The total excavated volume was 550,000 m3. Each coal silo is 65 m high and has a 40 m diameter with a circular plan cross-section. The volumetric capacity of each silo is 81,000 m3.
7 Ring Rail Line (Kehärata)
Airport transit is a new rail section connecting the city centre to Vantaankoski local track with the main northbound rail track. The whole project consists of 18 km of new double track and 8 new stations. Of this, 8 km of track and 4 stations will be fully underground. The owners of the project are the Finnish Rail Administration and the City of Vantaa.

Helsinki and Finland
Finland is perhaps best known for its peacefulness and beautiful nature. Vast forests, a unique archipelago and thousands of lakes present a striking mixture of wooded hills and waters (Figure 2). In addition to its mystical northern nature, Finland is also a modern Nordic country with a high standard of living and advanced economy and technology.
Helsinki, the capital of Finland, is a modern city with over half a million residents and is situated on the Baltic Sea. The archipelago that surrounds Helsinki with hundreds of tiny islands creates an idyllic environment for cruises, for example. Finland is a safe and reliable destination, easily accessible from all over the world. Helsinki is unique among Northern European cities (Fig. 3). The lifestyle in the second-most northern capital city in the world is full of contrasts and activities in the form of hundreds of events and friendly people. Finnish design has also made the country’s capital city world famous. Everything is nearby – Helsinki is a pocket-sized metropolis that is ideal for visitors!
