The expansion will ultimately connect Finland’s two largest cities, Helsinki and Espoo, and ease the traffic congestion in the metropolitan area. The work is for the second phase, which will result in five new stations within Espoo, west of the capital.
The total costs for the entire project are estimated at €1.8bn and work is scheduled to be completed in 2020.
Ramboll will manage the structural design of two stations, one metro depot and western part of the rail line jointly with Pöyry. It will also carry out the HVAC design of the entire rail section and its stations jointly with Granlund. The total value of the commissions exceeds €9m (£7m).
The design for the 7km Matinkylä-Kivenlahti metro stretch has been divided into two parts. On the western part of the rail line, Ramboll Finland has been commissioned for the structural design as part of a temporary consulting group with Pöyry Finland. The value of this commission is approximately €3.3m, and it comprises the structural design for the Kivenlahti and Espoonlahti stations, the Sammalvuori metro depot and the western part of the rail line.
The HVAC design commissions for both western and eastern parts were awarded to the consulting group Granlund – Ramboll Finland, with values of approximately €2.9m each.
On the eastern part of the rail line, the Sigma consulting group was chosen as the structural design consultant while Pöyry Finland has been assigned the rock engineering design.
Sweco PM was appointed as the project management consultant.
