New contracts signed

The contracts for excavation work for all six access tunnels on the Matinkylä-Kivenlahti metro line were signed today. The access tunnels in Finnoo and Sammalvuori will be excavated by Destia Oy. The value of the excavation contracts for these two access tunnels is approximately EUR 6.6 million.

Destia also won the excavation contracts for the Kaitaa and Soukka access tunnels, with a total contract price of EUR 6.4 million.

The Espoonlahti and Kivenlahti access tunnels will be excavated by Kalliorakennus-Yhtiöt Oy. The total contract price is EUR 7.9 million.

Access tunnels are initial access routes, approximately 500 metres in length, which are excavated into the rock from the construction site to the underground rail line. The access tunnel excavation will begin immediately and end by the autumn of 2015, after which excavation of the metro stations and rail lines can start.

Telog Oy won the contract for the antenna networks (GSM, VIRVE, WLAN). In this project, antenna networks will be built for the Ruoholahti-Matinkylä section to serve commercial operators, the authority network and the city WLAN network. The networks will be installed in both of the metro tunnels, at stations and in the access tunnels. The work will be completed by the end of 2015.

The seven-kilometre Matinkylä–Kivenlahti section of the metro line, running entirely underground, will include five new stations: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. In addition, an underground metro depot will be constructed in Sammalvuori.
The entire line from Matinkylä to Kivenlahti will be completed in 2020 at the earliest. The Ruoholahti–Matinkylä section of the line will be completed in late 2015 and will be open for traffic in the autumn of 2016.
