Destia builds metro tunnels for the Western Metro
The tunnel section contracted by Destia between Keilaniemi and Lauttasaari was completed in 2014. The contract included the structural engineering work for the metro tunnel over a distance of about four kilometres. It also included cast-in-situ structures for five vertical shafts and the installation of elements with related overground buildings. Destia was also responsible for the installation of the drying structures, emergency exit and cable duct elements and cable channels on the base of the tunnel.
Destia is currently working on the excavation of the work tunnels at Finnoo, Sammalvuori, Kaitaa and Soukka on the Matinkylä−Kivenlahti section in Espoo. The work tunnel contract will be completed in autumn 2015. Destia is also building feeder connections between Espoonlahti and Matinkylä. This contract includes the construction of public transport lanes and the improvement of pedestrian and cycle routes.
