Deliveries of prefabricated elements begin at Opettajantie shaft in Espoon-lahti 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 start at the Opettajantie shaft in Espoonlahti. At the installation stage of the prefabricated elements, the shaft is installed with prefabricated stairs, stair slabs, columns and wall elements over a total height of eight floors.

The installation work will begin in the week starting on 25 February 2019 and continue until the second week of June (the week starting on 3 June 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 between 7 am and 3 pm, 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 between 7 am and 6 pm.
