Excavation work in Espoonlahti to continue until the end of 2017
Rail tunnels of the West Metro’s second phase are being excavated in Espoonlahti. The rail tunnels to the west will be completed in August 2017 and the depot junctions and the Maininkitie shaft by the end of 2017.
In the near future, in early April 2017, superstructure construction work will begin at the Espoonlahdenkatu entrance. This work will also continue until the end of 2017. Excavation of the upper parts of the Maininkitie shaft and its collar structures will be completed in April–May 2017.
In addition to the metro worksite at Espoonlahti, other work under way in the area includes the construction of a shopping centre by Citycon Oyj and street construction by the City of Espoo. Information about these is available through their own communication channels.
Excavation work in Kivenlahti well under way
The last station of the West Metro’s second phase will be in Kivenlahti, where excavation work is well under way. The Kivenlahti tunnel’s eastern end, i.e. the affected area of Maininkitie, will be completed within approximately two months, after which bolt-boring will continue for around a month. The drilling work will be undertaken on weekdays from 7 a.m. to 6 p.m. and excavation blasting on weekdays before 10 p.m.
Excavation work at Kivenlahti station and its western end will continue until July–August.
The largest excavation work in Sammalvuori to be completed in June
As part of the West Metro’s second phase, an underground depot is being constructed in Sammalvuori. This night time depot for metro trains will also include maintenance facilities. Approximately half of the excavations for the connection rails have been done, and the aim is to complete the excavation of the largest masses by the end of June 2017. Blasting in Sammalvuori takes place on weekday mornings, usually around 7 a.m. to 9 a.m., and in the evenings from 7 p.m. to 10 p.m. Occasional blasting work may take place at other times.
Excavation of the shaft for the Sammalvuori gate has now been completed next to the S-Market in Kivenlahti. The next step will be reinforcement work, to be followed by construction work. Fixed vibration measurement units have been placed extensively in the area, and more of these will be added if needed as the excavation work progresses.
