Management of West Metro rail and stations handed over to HKL

Today, on Tuesday, 3rd of October, Länsimetro Oy and HKL signed a protocol transferring the management of the West Metro rail and stations to HKL. In practice, the transfer of management means that HKL may now fully begin the so-called initial production phase which precedes passenger traffic.

Länsimetro Oy remains responsible for a number of tasks which Länsimetro Oy shall finalise during the initial production phase before passenger traffic is commenced. The finalisation of these tasks has been scheduled.

The rail, its technical systems and the eight stations remain in the ownership of Länsimetro Oy. HKL shall report to Länsimetro Oy on the use of the rail and stations and the related service and maintenance tasks as agreed.

In a few days time, HKL will initiate the joint use of all 52 systems of the metro as well as their regular maintenance and testing. The systems control, for example, the technical building services, monitoring, operation, rail and safety of the West Metro. The systems are tested to ensure that they operate reliably and traffic services may begin without disruptions.

During the initial production phase, further test runs are also carried out for the entire metro line.

Before passenger traffic can begin, the systems must operate without disruption for a continuous period of two weeks in the initial production phase, after obstacles to the commencement of passenger traffic have been removed and the necessary tests completed. A sufficient number of successful test run days is required for the metro to be opened for traffic. After this, HSL shall decide on the commencement of passenger traffic.

The artist behind the artwork in Tapiola talks about its birth: influenced by Little My and Frida Kahlo

A large ponytailed statue stands on the bright white platform at Tapiola metro station – it is Emma leaves a trace, a newly unveiled work of art by the artist Kim Simonsson. The artwork Emma leaves a trace, funded by EMMA Espoo Museum of Modern Art, blends in with the rest of the station due to its white colour, but a colourful hand draws the viewer’s attention: Emma has clearly dipped her hand into a can of paint.

It took Kim Simonsson a long time to decide what kind of artwork he wanted to create for the public space – a metro station, which according to Strafica’s prediction will see approximately 26,000 passengers per day.

“In many ways it’s more difficult to design art for a public space than for a private commission, because the work has to be able to withstand use. Choosing the right material is important. The subject also has to be carefully considered because of the public location,” says Simonsson.

The final idea of a mischievous Emma, who leaves her handprints on walls, was born when Simonsson was out walking in Fiskars with his partner.

“I wanted the piece to be anarchic in one way or another, but not too much. On that walk, I thought of a child painting on a wall – painting on a wall is a very liberating experience,” says Simonsson.

The result was Emma, who was influenced by Little My and Frida Kahlo, among others, and whose idiom combines realism and the softness of animated characters. The hair of the statue was originally meant to be in a bun similar to that of Little My’s, but that did not come to be.

“These models, strong women, have often had buns, but it looked too static on a statue. There is a sense of spaciousness in a ponytail,” says Simonsson.

Emma stands firmly on the platform – the statue is bolted into the platform with half-metre-long bolts to make sure that it does not fall over. Emma’s material is durable bronze that is painted white apart from the hand.

Traces left by Emma can be seen at the station – the first ones are visible when going up the escalator towards the ticket hall. The wall is decorated by a colourful stripe combining green, yellow, red and blue. Similar traces of colour can be found throughout the station, and the story also continues as digital animation.

“Emma is a strong and independent character. It would be fun if she became friends with users of the metro station,” smiles Simonsson.

Emma Simonsson’s art work Emma leaves a trace really leaves traces around the station.

Construction work on the Sammalvuori depot has started – the consortium behind the excavation continues its work into the construction phase

Construction work on the Sammalvuori metro depot of the Länsimetro Matinkylä-Kivenlahti section has begun. Two underground halls are going to be built in the depot – one for the night-time storage of metro trains and the other for maintenance facilities. Technical facilities are also being built at the northern end of the maintenance hall.

There is currently only one metro depot in Finland – the Helsinki metro depot in Myllypuro. However, Länsimetro’s Sammalvuori depot differs from the solutions at the Myllypuro depot.

“The depot is being built completely inside bedrock. The depot commission includes excavation and construction work, as well as planning for the entire depot. This is an exceptional mode of operation and form of cooperation compared to Länsimetro’s previous contracts, and it requires new ways of thinking and close cooperation between all parties, which has already provided plenty of positive experiences during the excavation phase,” says Ulla Valtonen, Life Cycle and Risk Manager and Sammalvuori Depot Real Estate Development Manager from Länsimetro Oy.

The Sammalvuori excavation and construction consortium consists of Kalliorakennus-Yhtiöt Oy, EM Pekkinen Oy, Konevuori Oy and Aro-Systems Oy.

E.M. Pekkinen Oy is implementing the work carried out after the excavation, such as pipework, sewerage, bearing courses, access tunnel entrance structures and buildings constructed in the upper parts of the three shafts.

“We have previously carried out Länsimetro civil engineering works in Kivenlahti and Lauttasaari. It’s nice to be involved in projects like this one,” says Juha Tuppurainen, Construction Manager at E.M. Pekkinen Oy.

Kalliorakennus-Yhtiöt Oy is involved in the construction project in the implementation of for example, concrete structures for the depot and all fixed structures, such as station platforms, shafts, stairs and lifts.

“This is an interesting challenge and this new form of cooperation has worked well,” says Jukka Halonen, Managing Director of Kalliorakennus-Yhtiöt Oy.

Aro Systems Oy is responsible for the building services of the depot, including design and implementation of HVAC and electric systems.

“The systems that will be built, such as smoke extraction, lighting and heating, are familiar to us, but the conditions and operating environment are new. An interesting project on the whole,” says Simo Helskä, Building Services Project Manager of Aro Systems Oy.

Big day for connecting up tunnels: breakthroughs on four sites

On 7 September, the tunnels between a total of four construction sites will be connected on the west metro’s Matinkylä–Kivenlahti stretch. In the various contracts for the west metro, several tunnels are being excavated simultaneously and will eventually meet at the contract area boundary. The stone wall between the tunnels is 3–6 metres thick on average, and this wall will be removed during the breakthrough.

The last remaining thin rock plug separating the tunnels excavated between Kaitaa and Soukka will be blasted through on Thursday afternoon, and the breakthrough between the Sammalvuori depot and the Espoonlahti construction site will take place in the evening. The breakthrough between Sammalvuori and Espoonlahti will occur in phases: first, a narrower connection will be opened between the tunnels and then the hole will be enlarged. The breakthrough between Soukka and Kaitaa will be accomplished with a one-off blasting operation.

The first breakthrough for the second phase of the west metro was made on 10 August, between Kaitaa and Finnoo. This new breakthrough will open tunnel connections from the Kaitaa construction site to both of the surrounding tunnels.

Excavations on the west metro’s Matinkylä–Kivenlahti stretch are now 90% complete. The excavations will be followed by a construction phase that has already begun for Sammalvuori.

Rescue drill at the metro station in Tapiola on Friday 22 September

The Länsi-Uusimaa Department for Rescue Services will hold a drill at the Tapiola metro station on 22 September from around 9:45 to 15:00. In this drill, passenger safety on the west metro will be tested in a simulated evacuation in the actual operating environment of the metro.

During the drill, several emergency vehicles will be moving in the vicinity of the station. The drill will involve the use of harmless light grey smoke that is not hazardous to health. Smoke will be released from the metro’s smoke extraction shafts and will spread in accordance with the wind direction prevailing at the time. No calls to the Emergency Response Centre should be made concerning the smoke used in the rescue drill, unless the smoke originates from a source other than the drill.

The Department for Rescue Services regrets any inconvenience the drill may cause for local residents and companies and other people located in the area. In order to minimise any harmful effects, unnecessary visits to this area should be avoided. This drill will provide valuable information for improving the safety of metro traffic, which will benefit all of us.

Länsimetro Oy and HKL announcement: Commissioning of the west metro is proceeding according to plan

The commissioning of the west metro has now reached a phase in which HKL has been able to begin its own preparations for the launch of westbound metro services. Commissioning is currently proceeding as planned. According to estimates, metro services to Matinkylä may begin at the end of September at the earliest. 

On 4 September, the Helsinki City Rescue Department gave Länsimetro Oy permission to hand over the Koivusaari and Lauttasaari stations to HKL for preparations related to the start-up of metro services. On 31 August, the Länsi-Uusimaa Department for Rescue Services gave its permission regarding the six stations located in Espoo. The control centre systems released for use by HKL have been tested and it is estimated that they can be fully introduced next week.

HKL’s control room in Herttoniemi will monitor the operations of both the current metro and the west metro section. The purpose of the control centre systems (a total of 10 systems) is to monitor each of the 52 different systems of the west metro, as well as passenger safety, traffic and maintenance operations.  The systems include around 50,000 devices that must be monitored and approximately 27,000 planned annual maintenance and inspection activities. Control centre systems include the following: building technology supervision, HVAC and electric systems, power supply monitoring, a camera system, a public-address system, key control, access control, an emergency phone system and a fire detector system.  In addition, there is a traffic control system for metro trains. These systems can be taken into operational use in various phases of commissioning, for example in accordance with the instructions issued by rescue departments.

The commissioning of the west metro is one of the largest construction project handovers ever performed in Finland. The project has now proceeded from testing and official inspections to the commissioning phase, at the end of which HKL can open the west metro to traffic.  HSL will decide on the starting date for metro traffic when HKL has confirmed how long it will need for preparatory work.  Information on the progress of commissioning will be provided weekly on Fridays.
