The Sammalvuori consortium (Kalliorakennus-Yhtiöt Oy, EM Pekkinen Oy, Konevuori Oy, Aro-Systems Oy) has won the contract for the excavation and construction of the Sammalvuori metro depot. The work is due to begin in May, and the technical construction work will be completed in 2020. The total value of the contract is approximately EUR 51 million.

The contract includes the design, excavation and complete construction of the underground Sammalvuori metro depot.

– The excavation contracts of the second phase rail tunnels and stations are now all in progress. Good, experienced operators are now in place for each station, section of the line and depot. Of the 14 km long section, approximately 1.5 kilometres of the actual metro tunnel is excavated at present, says Länsimetro Oy’s CEO Matti Kokkinen.

The new stations on the seven-kilometre section from Matinkylä to Kivenlahti are Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. The section will be opened to traffic in 2020. Traffic to Matinkylä will begin on 15 August 2016.

Excavation of the second phase of the West Metro underground line can be followed via the monitoring service on the Länsimetro website. The service shows the progress of the excavation, the rail line and the location of stations and shafts.
