Deliveries of prefabricated elements begin at Riihilahdentie shaft for construction of emergency exit and smoke extraction shaft

In the West Metro rail line construction project, the construction of the emergency exit and the smoke extraction shaft will begin with the Riihilahdentie shaft in Kaitaa. During the installation stage of the prefabricated elements, prefabricated stairs, stair slabs, columns and wall elements will be installed in the shaft over a total height of eight floors.

The installation work will begin in the week starting 25 March 2019 and will continue until 31 July 2019. Prefabricated elements will be delivered to the site at a rate of two loads per week at 7 am.

In addition, concrete mixer trucks will deliver fresh concrete for the casting once or twice a week. Cranes will mainly be used outside the period of 7 am–3 pm on weekdays, and passenger cars and vans will otherwise be used for site traffic.

Once the installation work has been completed, construction will continue with work on the aboveground structures of the shaft. Work at the shaft will be carried out from Monday to Friday between 7 am and 6 pm.
