International expertise for the second phase – smoke extraction fans to be supplied by Talleres Zitrón S.A.

Smoke extraction fans for the Matinkylä-Kivenlahti section will be supplied by Spanish manufacturer Talleres Zitrón S.A. The total contract price is EUR 1.8 million.

Smoke extraction fans are used in the event of fire to exhaust smoke from underground areas through smoke zone routes to open air. Smoke extraction fans are installed on vertical shafts in the metro line and in the east and west ends of stations. The second-phase metro line and stations will have a total of 15 extraction fans. Talleres Zitrón also supplied a total of 32 extraction fans for the first phase of the West Metro from Ruoholahti to Matinkylä.

Operation of the smoke extraction fans was tested on the first phase of the West Metro by means such as passenger rescue drills before metro service was begun. The 52 different systems of the West Metro guarantee passenger safety at all times, including emergencies. High-performance smoke extraction fans exhaust smoke quickly through the correct routes to ensure that passengers can be evacuated safely.  In the West Metro, the movement of passengers between tunnels has been facilitated by, for example, constructing fire compartmented connecting tunnels in intervals of some 150 meters and by equipping both tunnels with prefabricated concrete units whose covers that serve as emergency exits.

Talleres Zitrón supplies smoke extraction fans for demanding applications, such as the metro projects in London, Milan and Rome. The company has supplied extraction fans to some 100 metro systems around the world.  The first smoke extraction fans will be delivered to Kivenlahti in the summer of 2019.

The second phase of the West Metro is estimated to be completed in 2023. This year, work has progressed from excavation to construction.  The project management contractors for all five stations and the rail line have been selected, and construction will begin at all stations by the end of the year. On the rail line, some 360 supporting wall elements have already been installed over a distance of 1.5 kilometres. The tendering of subcontracts will continue until summer 2019. At the Sammalvuori depot, work has already progressed to technical building services.

Construction on the stations and rail line will continue until 2022, after which the project will proceed to the commissioning phase. This includes the acceptance of contracts, extensive testing and regulatory approvals. Länsimetro’s share of the project will be completed once the metro is handed over to the operator to begin preparations for passenger traffic.

SRV selected as constructor for Espoonlahti metro station

SRV has won the project management contract for the Espoonlahti station on the Matinkylä–Kivenlahti section of the West Metro. The total contract price is approximately EUR 48 million. All project management contractors for the second phase have now been selected, and construction will be underway at each station by the end of the year.

In Espoonlahti, the contract includes the construction of the underground metro service tunnel, its entrances on Espoonlahdentori and Solmutori, a bus terminal adjoining the Lippulaiva shopping centre and a service tunnel and connecting tunnels to the station.

“The Espoonlahti metro contract is a natural continuation to other contracts carried out by SRV for the metro. At this site, we will be able to demonstrate our expertise in the management and implementation of demanding projects. In 2016, SRV oversaw the completion of the Koivusaari metro station as the project management contractor. In addition, SRV has previously carried out the station and tunnel excavation and reinforcement work for the Otaniemi and Kaitaa metro stations of the West Metro,” says Antti Raunemaa, Head of Unit at SRV.

Construction of the second phase is on schedule and within the cost estimate. This year, work has progressed from excavation to construction. Work is already underway in Kivenlahti, Soukka, Kaitaa, Finnoo and on the rail line. Construction of the Espoonlahti station will also begin by the end of the year. At the Sammalvuori depot, work has already progressed to technical building services.

“Tendering is now complete for all major contracts for the second phase. We have found experienced contractors for each of the stations and the rail line. The market situation has remained good, competition has been sufficient and as a whole, procurement has been carried out smoothly. Tendering for the subcontracts will continue until spring 2019,” says Ville Saksi, CEO of Länsimetro Oy.

In March 2018, the City of Espoo reviewed its project plan for the second phase from 2012. The revised cost estimate for the entire project is EUR 1,159 million. The aim is to hand over the seven kilometres of rail line and five stations and depot to the operator, Helsinki City Transport, during 2023.

War room keeps the whole project up to date

One of the project management tools in the second phase of the West Metro is a war room which continuously generates real-time information on the project schedule and costs. Another aim is to streamline communications between all parties to the project.  

In the West Metro’s big room, a situational picture of the overall project is continuously monitored from real-time digital displays. This involves a war room which has been in use for the project since the spring of 2018.

“Our goal is to obtain accurate, real-time and sufficiently clear information to enable problems to be tackled right away. To achieve the budget and schedule-related goals of the second phase of the West Metro, we had to create a new way of managing the project and thinking about project management,” says Timo Heiskanen, War Room Manager at Länsimetro.

The progress of the seven sub-projects – the five metro stations, the depot and the line – is tracked throughout the construction cycle, from the planning, acquisition, permit application and execution phases onwards. As well as the project schedule, the costs, risks, quality, smoothness of cooperation and occupational safety are monitored, using a ‘traffic light’ system, from the war room.

“These are the elements that create a successful project,” says Heiskanen.

War room data enables real-time management and troubleshooting by the project management.

“The project management meets regularly in the war room to discuss each sub-area in face-to-face meetings. This ensures that everyone is on the same page and can decide on corrective measures, if necessary,” says Jaakko Naamanka, Project Manager of the Matinkylä-Kivenlahti project.

The construction of just one West Metro station is the equivalent of building a large shopping centre underground. A project of this size involves a range of actors – real estate developers, designers, equipment suppliers, contractors and the public authorities – all of which must keep to the same schedule and pull together.

“Each operator is responsible for its own area: the basic principle is that the schedule is non-negotiable. It is my job to make the schedule as clear as possible to everyone,” says Heiskanen.

A war room or situational snapshot means more than just monitors on a wall – they are part of an overall set of practices, holistic processes and a management culture.

“The primary purpose of the war room is to communicate the situation to the different parties. Communication is a priority in large projects. When working towards a common goal, each actor must understand the impact of its work on the overall project. When developing the current model, we aimed at achieving the clearest possible communication on matters involving complex technical data,” says Heiskanen.

Work begins on Finnoo station

Construction of the West Metro’s station stop in Finnoo is set to begin in October 2018. The contractor is a consortium formed of Graniittirakennus Kallio Oy and Aki Hyrkkönen Oy.

The contract covers the construction of the underground station, a service tunnel and connecting tunnels as well as exits on Meritie and Finnoonsilta. Access shafts for engineering works will be built to the east and to the west, and a firefighting shaft will also be provided.

The first step is to set up a base for the works. The works will begin with the construction of a framework for the station’s platforms, including concrete walls, columns and arches. The framework construction begins from the bottom up, advancing floor by floor towards the surface.

During construction, there will be an increase in construction traffic around the mouths of the shafts and access tunnels. Otherwise, construction will cause no major changes in the surrounding environment.

During the construction phase, quiet work may be done around the clock, but noisy work may be done according to the noise permit issued by the Espoo Environment Agency:

  • between 7 am and 6 pm from Monday to Friday
  • between 6 pm and 10 pm from Monday to Friday and between 9 am and 6 pm on Saturdays, provided that the resulting noise levels in nearby residential properties do not exceed 35 dB

The West Metro’s Matinkylä–Kivenlahti section is due to be built between 2019 and 2022. All in all, the construction phase of the project comprises the construction of five stations, tracks and a depot in Sammalvuori as well as the installation of various systems. Work will be handed over by the contractors in 2022– 2023, followed by joint use tests and official inspections. The operator, Helsinki City Transport, will take over the stations and the track in 2023 in preparation for launching passenger transport.

More information about the construction works in Finnoo will be provided at a residents’ meeting at Iivisniemi School (Arttelkuja 4) between 5.30 pm and 6.30 pm on Monday, 8 October 2018. We look forward to seeing you there!

RIA Member of the Year 2018, Länsimetro Oy’s CEO Ville Saksi: “This award is for the whole team”

The Association of Finnish Construction Engineers and Architects (RIA) has chosen Länsimetro Oy’s CEO Ville Saksi as RIA Member of the Year 2018.

RIA wanted to give Saksi recognition for his solid leadership skills and construction know-how as well as his broad experience of all areas of the industry. The panel based its choice on Saksi’s exemplary leadership of a challenging project that has allowed him to gain the trust and respect of all the partners and workers involved in the project.

“Being voted RIA Member of the Year was a pleasant surprise. However, I would like to stress that complex projects such as this one are always a team effort and not a personal achievement, and this award is for the whole team”, Saksi says.

Before Länsimetro Oy, Saksi was the CEO of VR Track Oy. He has a bachelor’s degree in industrial engineering.

Works on the West Metro’s Matinkylä–Kivenlahti section are currently progressing well in light of all the key indicators.

“All the tunnel excavation works have been completed, and approximately 70% of the construction budget has been spent. Our contractors have also been happy with the chosen contracting model. It seems that we have succeeded in winning the contractors’ trust”, Saksi says.

The RIA Member of the Year award will be presented to Saksi next week.

Light at the end of the tunnel: all exits along the Matinkylä–Kivenlahti section now open

All the stations and access shafts for engineering works along the West Metro’s Matinkylä–Kivenlahti section now have exits above ground. The last shaft, which provides an exit from the station in Soukka on Yläkartanontie, broke through to the surface on Monday, 8 October.

There are a total of 19 exits and access shafts along the Matinkylä–Kivenlahti section. All the rail tunnel sections have been interconnected since February 2018.

“The exit is now in place, but we still need to shape the archway this week. There is therefore still some excavation work to be done. The next steps will involve removing excavated rock and reinforcing the structures, bolting and shotcreting”, explains Construction Manager Meeri Kaartinen from Kalliorakennus-Yhtiöt Oy, which is the excavation contractor.

After the Yläkartanontie exit, the only building site along the Matinkylä–Kivenlahti section where excavation work is still needed will be an exit on Solmutori in Espoonlahti. All excavation works will nevertheless be completed by the end of 2018. The site in Soukka has now progressed to the construction phase, and the final excavation works and construction works are being carried out simultaneously. Other active building sites relating to the project can be found in Kivenlahti, Kaitaa and at various points along the track, and construction works in Finnoo are due to begin in October. The construction of the Espoonlahti station is scheduled to start in December.

Elevators and escalators for the stations along the Matinkylä–Kivenlahti section to be supplied by KONE

KONE Elevators Ltd has been chosen as the supplier of the elevators and escalators for the Matinkylä-Kivenlahti section. 31 elevators will be installed, 4 of which will be inclined elevators.  The price of the elevators is EUR 6.7 million. KONE Elevators Oy also won the escalator tender. There will be 14 groups of escalators (42 escalators) on the section, the longest of which will be installed in the Finno station. The longest escalator in Finland can currently be found at the Koivusaari station. The price of the escalators will be EUR 11 million.

A passenger’s metro journey either begins or ends with escalators or elevators. The user experience is enhanced when planning and implementation take account of people’s everyday behaviour. The number-one priority is safety, but comfort and reliability are also important considerations.

“Many of the technical systems on which the West Metro relies are not visible to passengers. Elevators and escalators are a visible and important part of underground travel, passengers’ experience and accessibility at underground stations. KONE is a global supplier with experience of moving large numbers of passengers around in places such as the biggest cities in China. The underground systems there can serve millions of passengers on a daily basis”, explains Länsimetro Oy’s CEO Ville Saksi.

The West Metro is one of the safest underground systems in the world. Since the elevators are fire-compartmentalised, they can also be used during fires. Special attention has also been given to the comfort of elevators and escalators: the stations are brightly lit and the elevator shafts are predominantly made of glass, the announcements on the public address system have been customised and there is a display inside each elevator that tells passengers the time remaining until the next level.

“It is a great pleasure and honour for us to also be involved in the second stage of the West Metro project. This project is perfect for our mission: to improve the flow of urban life. Our solutions for moving large numbers of people around and our smart KONE 24/7 Connected Services concept allow us to make underground travel an even smoother experience for passengers”, says KONE Elevators Ltd’s Managing Director Karla Lindahl.

Installation works for elevators and escalators are due to begin towards the end of 2019. The goal is to hand over the seven-kilometre rail line together with its five stations and depot to the operator, Helsinki City Transport, during 2023.

Contract awarded for the supply of tracks for the Matinkylä–Kivenlahti section

The tracks for the Matinkylä–Kivenlahti section will be supplied by Vossloh Rail Services Finland Oy. The budget for the works is EUR 2.0 million.

The contract covers laying a total of 34 kilometres of tracks. The tracks are being welded in Kaipiainen near Kouvola, and they will be supplied in 120-metre pieces. The tracks will enter the tunnel in Vuosaari, from where they will be transported through the existing underground network all the way to the beginning of the new section. The deliveries will take place at night so as to not disturb passenger transport. Tracklaying is scheduled to begin towards the end of the summer of 2020 in connection with superstructure works.

Vossloh Rail Services Finland Oy also supplied the tracks for the first section of the West Metro, and the company is the leading operator in the industry in Finland.

Excavation works along the line being constructed during the second stage of the West Metro project were completed in January 2018. The construction of the Matinkylä–Kivenlaakso section began in the summer of 2018.  Graniittirakennus Kallio has been contracted to construct 17.5 kilometres of new tracks, seven shafts and 32 connecting tunnels. The goal is to hand over the seven-kilometre rail line together with its five stations and depot to the operator, Helsinki City Transport, during 2023.
