Stabilisation work at the Riilahti shaft will begin in week 46. Stabilisation involves the installation of 125 concrete pillars in order to prevent any land subsidence. Pillar stabilisation will take approximately 5 weeks. After this, the installation of drilled piles will begin at the shaft at the beginning of 2017, in week 2. The estimated duration of drilled pile installation is 7 weeks. According to a preliminary estimate, shaft excavation will begin in September 2017. This will be carried out by drilling above the ground. The actual entrance shaft will be excavated from underneath in the tunnel. Signals will be sounded to warn about any excavation. Work in the area will continue into the latter part of 2017.
The working hours for all phases of superstructure construction are Monday to Friday, 7.00 to 18.00.
We apologise for any inconvenience caused by the work.
