Lemminkäinen has won the Finnoo station and rail line excavation contract

28.3.2016

Lemminkäinen Infra Oy has won the Finnoo station and rail line excavation contract. Work begins in March 2016, and the contract is due for completion in October 2017. The total contract price is approximately EUR 36 million. In addition to the excavation of Finnoo station and rail tunnels, the contract covers the excavation of a new wastewater tunnel. All in all, 1,380 metres of new metro line and 771 metres of drain tunnels will be excavated.

– The excavation of Soukka and Kivenlahti stations and rail line is in progress. Excavation work is about to begin in Kaitaa and Finnoo and at the underground metro depot in Sammalvuori. Work in Espoonlahti will start later in the spring, says Matti Kokkinen, CEO of Länsimetro Oy.

The section from Matinkylä to Kivenlahti will be seven kilometres long and include the new stations of Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. In addition, an underground metro depot will be constructed at Sammalvuori. The stretch will be opened to traffic in 2020. Traffic to Matinkylä will begin on 15 August 2016.

Länsimetro Oy is a company jointly owned by the Cities of Espoo and Helsinki, tasked with building the West Metro underground line. The Ruoholahti–Matinkylä section will open to the public in August 2016. Construction of the Matinkylä–Kivenlahti section is under way. This stretch will be completed in 2020.

Seven-year project to be completed in August

8.3.2016

The eight stations and 14 kilometres of track to Matinkylä are due to open to the public on 15 August 2016. The excavation and building works have employed approximately 1,500 builders, and the total workload across the project will amount to approximately 4,500 person-years. The final cost estimate for the project is EUR 1,088 million. The project plan gave the cost of the project as EUR 713.6 million (at 2007 prices). Taking into account the rate of inflation, the cost estimate was EUR 848.0 million. The final cost of the project will therefore be EUR 240 million, or 28.3%, higher than planned.

Excavation works began in November 2009. The tunnels had been dug by February 2014, and the tracks had been laid by December 2015. In addition to new stations and two parallel rail tunnels, the project has involved building 15 vertical shafts for emergency exit, ventilation, pressure relief and smoke extraction purposes, nine sets of points, and a total of 54 cross passages between the twin tunnels. Passenger safety is ensured by the underground network’s 52 different automation systems. Safety is further reinforced by systems such as 32 smoke extractors, automatic smoke detection systems, fire extinguisher systems and fire escapes, as well as eight auxiliary power units. All the entrances to the underground are wheelchair accessible. There are a total of 46 lifts and 72 escalators in the underground.

The various systems will be tested independently, per station, and together during the spring. Trains will begin test runs in March. Once the line opens to the public, bus routes that previously terminated in Kamppi will be extended to provide a connecting service to Matinkylä and Tapiola according to a plan drawn up by Helsinki Region Transport. Underground trains will run more frequently than they do now. Two underground lines will be in operation: Matinkylä–Vuosaari and Tapiola–Mellunmäki. At peak times on weekdays, trains will run at 2.5-minute intervals on the section shared by both lines (Tapiola–Itäkeskus). Underground trains currently run at four-minute intervals during peak times.

Excavation for Kivenlahti metro station and rail tunnel to begin

27.11.2015

The excavation for the Kivenlahti metro station and rail tunnel will begin soon, with Kalliorakennus-Yhtiöt Oy as the excavation contractor. The work will begin immediately after the completion of the excavation of the access tunnel during November and December. The Kivenlahti worksite area will expand, resulting in Kivenlahdentie to be closed for traffic between Kivenlahdenkatu and Merivirta as of 4 January 2016. An entrance to the station will be built on Kivenlahdentie. Car and bus traffic will be directed to an alternative route as seen in the attached map. There will be no bus traffic in the closed area. The bus stops on Kivenlahdenkatu and Merivirta will be in use as usual, and two new bus stops will be added along Merivirta. Pedestrian and cycle traffic on Kivenlahdentie will be directed around the worksite area. Merivirta will also be equipped with pedestrian crossing traffic lights.

Another entrance to the station, the Kivenlahdentori entrance, will be built on the site of the temporary dog park. Work on the site will begin with earthmoving. The dog park will be relocated west of the worksite area. The dog park will permanently move to Ruukinmäki in the summer of 2016.

These temporary traffic arrangements will remain in force until the construction process is complete, at least until 2020.

Working hours at the site, as determined by the Espoo Environment Institute, are as follows:
