Skanska Infra wins the first station and rail tunnel excavation contract for Länsimetro’s 2nd phase

Skanska Infra Oy has won the first station and rail tunnel excavation contract for Länsimetro’s Matinkylä–Kivenlahti section. Skanska will excavate the site of the Soukka station, approximately 1.5 kilometres of twin tunnel, a rail switching hall and the necessary shafts to the surface. This contract is worth EUR 26.9 million and work will begin in October.

– Construction of the Länsimetro line from Matinkylä to Kivenlahti is progressing according to plan. The metro will enable the development of the regions surrounding the stations and provide the Espoonlahti Centre with a connection to the metro, in addition to Tapiola and Matinkylä, said Olli Isotalo, Chairman of the Board of Länsimetro and Head of Technical and Environment Services in Espoo.

– This contract forms part of a large project portfolio and marks the continuation of our cooperation that dates back to 2011. The previous contracts delivered by Skanska Infra included the excavation of the metro and connection tunnels and shafts related to the Tapiola station, as well as the construction of the tunnel between Ruoholahti and Lauttasaari. Skanska is also responsible for the ongoing construction of the Keilaniemi and Lauttasaari metro stations, said Ari Huovila, Managing Director of Skanska Infra Oy.

Two other contracts were also signed on 24 September. Drillcon SMOY will supply rock mechanical monitoring systems for Länsimetro. The total contract price is EUR 580,000. Finnrock Oy was selected to perform property reviews and vibration monitoring in the area affected by excavation. The contract price is EUR 250,000.

Excavation of the access tunnels in the Matinkylä–Kivenlahti section began in December 2014. After they have been completed, the excavation of stations and rail tunnels will begin and continue into the latter part of 2017. The Matinkylä–Kivenlahti stretch is seven kilometres long. The new stations will be Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. The stretch will be opened to traffic in 2020. Traffic to Matinkylä will begin on 15 August 2016.
