Länsimetro Oy is a company jointly owned by the Cities of Espoo and Helsinki, tasked with building the West Metro underground line. The aim is to complete construction of the Ruoholahti–Matinkylä section by the end of 2015. Construction of the Matinkylä–Kivenlahti section is under way. This stretch will be completed in 2020. www.lansimetro.fi

The construction of the west metro on the Ruoholahti–Matinkylä section will mostly be completed by the end of 2015. The installation of tracks will begin on the second week of February in 2015, and the metro rail from Ruoholahti to Matinkylä will be ready for traffic in January 2016. Test runs will begin after this. The aim is to open the Ruoholahti–Matinkylä section for passenger traffic in August 2016. Excavation of the access tunnels in the Matinkylä–Kivenlahti section is under way. This section will be completed in 2020.

“The dissolution of the contract between HKL and Siemens on the automation of the metro means that operation will initially be manual. The condensing urban structure in both Helsinki and Espoo, however, will require the metro train system to be automated in the 2020s. “This will ensure that the trains run at sufficiently frequent intervals and that a good service level can be maintained,” explains the Chairman of the Board of Länsimetro Oy, Olavi Louko.

Construction is progressing at stations and on the rail line 73 per cent of the concrete pouring for the stations on the Ruoholahti–Matinkylä line has been completed. 84 per cent of the support wall elements at the sides of the tunnels have been installed, and 13 per cent of the track ballasting has been completed.

“Our aim is that the metro will be opened for traffic in August 2016. Construction is now progressing briskly, and we have 1,200 construction professional at work. The worksites on the Matinkylä–Kivenlahti section have also started operations, with over 100 employees already at work,” says Länsimetro Oy CEO Matti Kokkinen.

The Helsinki City Council decided on the automation of the metro in 2006. The project plan for the Ruoholahti–Matinkylä section was completed in 2008. Construction of the first phase started in 2009.

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.

The interior preparation phase has progressed with the construction of partitions and performance of paintwork. In addition, preparation of the mosaic concrete floor and the installation of metal parts have begun in the harbour area. The next visible work phase will be the construction of the station building’s roof at the beginning of next year.

As a rule, heavy vehicles leaving the construction site will pass through the Hanasaari junction. Large vehicles that cannot navigate the Hanasaari junction will use Sotkatie. The primary construction phase of Koivusaari metro station will last until the end of 2014, after which the number of heavy vehicles visiting the construction site will drop dramatically.

During week 51, a temporary storm water run-off connection will be built at the end of Vaskisalmenkuja. The area will be ring-fenced and passage will be arranged around the excavation.

180 construction experts are currently working at the site.

Construction of the Kaitaa access tunnel will begin in December. Work will be started with earthwork. The open excavation phase is scheduled to take place in February–March 2015. Blasting for open excavation will be announced by a series of short signals before the blast and a long signal afterwards.

It is estimated that the actual excavation of the access tunnel will begin in April 2015. The excavation work for the access tunnel will continue until October 2015.

After the access tunnel project, a metro tunnel and metro station site will be excavated. During both work phases, excavated rock will be taken to Länsiväylä and further afield for use in other construction projects. Haulage will be based on the blasting times. Blasting will occur 1–3 times a day.

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

Earthwork and excavation work
• Mon–Fri 7–18 (quiet work also between 18–22, Sat 9–18)
Tunnel excavation (grout hole drilling, drilling, scaling)
• Mon–Fri 7–18 (quiet work also between 18–7)

The beginning of the construction on the metro line from Matinkylä to Kivenlahti was celebrated today at the Finnoo access tunnel worksite in Espoo. Work has started with the construction of access tunnels close to the future stations and at the underground metro depot in Sammalvuori. Access tunnels are initial access routes excavated into the rock from the construction site to the actual rail line. The excavation of the metro tunnels and stations can begin after the excavation of the access tunnels.

– Extensive infrastructure projects are significant for employment in the current economic situation, stated Antti Rinne, Minister of Finance, in his speech at the event.

Jussi Pajunen, the Mayor of Helsinki, emphasised the cooperation between the cities.

– It is great to see that the smooth cooperation between Helsinki and Espoo continues in the metro project. The metro is an important public transport project for the whole metropolitan area, emphasised Pajunen.

The Chairman of the Board of Länsimetro, Olavi Louko, who is the Head of Technical and Environment Services in Espoo, pointed out in his speech that the construction does not only concern the metro, but also the possibilities that the metro will offer in the future.

– We are not only constructing a metro, but a new closer urban structure that enables the creation of new jobs, housing construction and the development of services.

The contractor’s representative at the event was Minna Heinonen, Executive Vice President at Destia Oy.

– Safety is our top priority. The objective at this worksite, as at all other worksites, is zero accidents.

The seven-kilometre Matinkylä–Kivenlahti section of the underground line will include five new stations: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. In addition, an underground metro depot will be constructed at 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.
