Länsimetro Oy has awarded Pöyry with rock, geotechnical and structural engineering assignments for its Western Metro project in Finland, between the districts of Matinkylä and Kivenlahti. On the western part, services include structural engineering of the rail line, two underground stations, and underground pit and the shafts. On the eastern part, services include rock and geotechnical engineering of the rail line, shafts and three underground stations. The total length of the leg is approximately 7 km. The structural engineering assignment will be executed in a consortium with Ramboll Finland Oy.
The Matinkylä-Kivenlahti metro extension will run in Espoo, the second largest city in Finland. It will be part of the metro system in the Helsinki capital region. The Western Metro between Matinkylä-Kivenlahti is estimated to be ready in 2020. Overall, the Western Metro will transport 170,000 passengers per day, decreasing car traffic and emissions. Construction of the tunnels requires complex geotechnical and structural engineering competency.
Pöyry has also provided engineering services for the first leg of the Western Metro line, which is currently under construction and is scheduled to be in operation in 2016. The end station of the first leg will be Matinkylä.
“Pöyry’s experience in demanding underground rail transportation projects helps us in achieving our goals for the design and implementation”, says Matti Kokkinen, Managing Director of Länsimetro Oy.
“Safety, functionality and efficient implementation are the top priorities for Pöyry in designing solutions for rail, road and underground projects. We are honoured by Länsimetro’s trust in our competence and of the continued cooperation”, says Mikko Inkala, Pöyry’s President of Infrastructure Design in Finland.
The combined value of the orders is EUR 3.9 million. The orders will be recognised within the Regional Operations Business Line order stock in Q4 2014.
