The West Metro expands towards Kivenlahti
The second phase of the West Metro is under construction from Matinkylä in Espoo to Kivenlahti. In all, a seven kilometre long line and five new stations are under construction: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti.
The construction contract for the Finnoo station will be carried out by a consortium formed by GRK Infra Oy and Aki Hyrkkönen Oy. Granlund Oy is responsible for the design of HVAC, electricity and automation. The architectural design was planned by PES-Arkkitehdit Oy.
The construction contract for the Kivenlahti station is carried out by Skanska Infra Oy. Granlund Oy is responsible for the design of HVAC, electricity and automation. The architectural design was planned by Arkkitehtitoimisto ALA Oy.
Biddle air curtain units
High-quality intelligent and high-performance Biddle air curtains were selected for the projects. Stravent will deliver a total of 18 SR air curtains for the station’s platform-level escalator and elevator lobbies as well as for the ground level main doors in 2020.
The most significant qualitative differences in the units are in the SFP value and automation, i.e. how the air curtain is controlled and how it is able to take into account door heights and changing conditions. Biddle units are selected and tuned according to the door size. The design air volume of the air curtain is adjusted according to the door size (width x height) and calculations are prepared for this. For devices from other manufacturers, the installation height is not taken into account in the same way, and the device cannot be dimensioned in the same way for a specific door size.
