Construction of the West Metro’s station stop in Kaitaa is set to begin in September 2018. The contractor is a consortium formed of YIT Construction Ltd and Are Oy.
The contract covers the construction of the underground station, a service tunnel and connecting tunnels, an air raid shelter as well as an exit on Kaitaantie, an access shaft for engineering works on Iivisniementie and the framework for an exit at Iivisniemenkallio, which at this stage consists of an emergency exit route and an access shaft for engineering works.
The first step is to set up a base for the works at Kaitaantie 5. The works will begin with the construction of a framework for the station’s platforms, including concrete walls, columns and arches. The framework construction begins from the bottom up, advancing floor by floor towards the surface.
During construction, there will be an increase in construction traffic around the mouths of the shafts and access tunnels. Otherwise, construction will cause no major changes in the surrounding environment.
During the construction phase, quiet works can be carried out around the clock, while any activities that produce high levels of noise are limited to times specified in the noise permit issued by the Espoo Environment Department:
- between 7 am and 6 pm from Monday to Friday
- between 6 pm and 10 pm from Monday to Friday and between 9 am and 6 pm on Saturdays, provided that the resulting noise levels in nearby residential properties do not exceed 35 dB
The West Metro’s Matinkylä–Kivenlahti section is due to be built between 2019 and 2022. All in all, the construction phase of the project comprises the construction of five stations, tracks and a depot in Sammalvuori as well as the installation of various systems. Work will be handed over by the contractors in 2022– 2023, followed by joint use tests and official inspections. The operator, Helsinki City Transport, will take over the stations and the track in 2023 in preparation for launching passenger transport.
More information about the construction works in Kaitaa will be provided at a residents’ meeting at Martinkallio School (Martinkallio 2) between 5.30 pm and 6.30 pm on Monday, 24 September 2018. We look forward to seeing you there!
