Contract tendering for the second-phase will continue – the YIT-Are consortium will build the Kaitaa station

The construction tender for the Kaitaa station on Matinkylä-Kivenlahti section of the West Metro has been won by the YIT Rakennus Oy and Are Oy consortium. The total contract price is EUR 47 million.

The construction project will involve previously excavated areas for the Kaitaa underground station, a service tunnel and chambers for its connecting tunnels, a civil defence shelter and the Kaitantie entrance, the Iivisniementie technical shaft and the space reserved for the Iivisniemenkallio entrance, in connection with which an exit road connection and technical shaft will be built at this stage.

Construction of the Kaitaa station will be carried out by YIT and the Are consortium. The consortium will also build the Soukka station.

“Our skilled personnel, strong experience in the construction of rock chambers and effective cooperation with Are have contributed to achieving the outcome we sought through the West Metro tendering exercise. We are delighted that, in the second phase of the West Metro, we can engage in the project management of the Kaitaa station’s construction in addition to the Soukka station. A collaborative approach and close cooperation with the customer organisation create an excellent basis for a successful project,” says Anne Piiparinen, Senior Vice President in charge of technical construction Infrastructure projects segment at YIT.

The surface area of the facilities to be built is around 22,900m2. A total of around 8,300m3 of concrete will be cast and over 11,000 m2 of various elements installed.

“Our consortium combines long expertise and experience of challenging projects within both companies, which we were also able to demonstrate in the tender for the Kaitaa station. Are is strongly committed to bringing the best building services expertise to the construction of both the Soukka and Kaitaa stations,” says Kai Nurho, Director Building Services Contracting at Are.

In addition to the tendering process, the objectives of phase two of the West Metro’s construction in 2018 include the completion of excavation work and the acquisition of building permits for the stations. Construction is progressing according to objectives.

“Around 60 percent of the technical construction work for the Sammalvuori depot has already been completed.  Construction work has begun in Soukka, in Kivilahti and on the railway line. The project management contractors for the Finnova and Espoonlahti stations will be chosen next. As a whole, the project is progressing according to schedule. The aim is to hand the Metro over to the traffic operator, HLK, in 2023,” 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 goal is to hand over the seven-kilometre rail line together with its five stations and depot to the operator, HKL, during 2023.

Excavation until December at the Yläkartanontie entrance

The excavation of the Yläkartanontie entrance is underway at the Länsimetro Soukka worksite. Yläkartanontie is one of the two entrances to the completed Metro station. The excavation work will continue on Yläkartonantie, in accordance with an updated schedule, until the end of December 2018.

Excavation and tunnel reinforcement work will be carried out between September and December. Noisy work phases may occur on weekdays between 7am and 6pm on Monday to Friday at Soukantie 12 and 14 and Yläkartanontie 29 and 30. The working hours are based on a noise permit granted by the Espoo Environment Centre.

Excavations of the tunnels at the Soukka worksite were finished at the end of the summer of 2017. Construction of the Soukka Metro station also began in August 2018, and will proceed in parallel with excavation during the autumn of 2018.

 

Länsimetro’s financial administration strengthened by new project controller

Länsimetro has a new Project Controller, Sami Järvinen (Bachelor of Business Administration). He will add valuable expertise to Länsimetro’s financial administration, and will work in close cooperation with the CFO. He will focus on Länsimetro’s cost monitoring, accounts monitoring and control, and both internal and external reporting.

His previous positions include a software trainer for financial administration employees at software developers Heeros Oy, and financial administration assistant at Work Power Oy. Before choosing financial administration, he has also worked as a plumber in Australia.

“Construction is still close to my heart, so I am happy to be part of this project,” says Järvinen.

Järvinen will continue his Master’s studies at Oulu Business School at the University of Oulu in the autumn of 2018, but Länsimetro made such an interesting job offer that he just couldn’t let it pass.

“The size of the project on a Finnish and indeed European scale is interesting, and I cannot wait to get started,” he says.

The worksite area for the service tunnel expanding in Espoonlahti – pedestrian detour through Ulappakatu

The worksite area of the Espoonlahti service tunnel will be expanded as of the week beginning on 23 July.

Owing to this change, part of the pavements and bicycle ways will be unavailable, and the pavements and bicycle ways on Ulappakatu should be used instead.

The new worksite area will be fenced off by 29 July. The expansion of the worksite area is related to the beginning of construction on the Espoonlahti metro station, and these changes apply until construction has been completed.

The worksite area and the new routes for pedestrians and cyclists are shown in the attached map.

Construction begins on Soukka station

The construction of the Soukka station will begin in August 2018. The work is carried out by Työyhteenliittymä YIT-ARE RU23 (a consortium of YIT Rakennus Oy and Are Oy).

The work consists of building Soukka metro station, its technical shafts, two entrances and a service tunnel extending from Soukanväylä to the station. The surface area of the underground facilities is about 20,000 m2. A total of almost 11,000 m3 of concrete will be cast. The station entrances will be in Soukantori and Yläkartanontie.

The work will begin with the construction of a worksite base at the Soukantie worksite area. The construction of the station begins with the platform level’s framework, consisting of concrete walls, pillars 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:

  • weekdays from Monday to Friday, 7am–6pm
  • weekdays 6pm–10pm and 9am–6pm on non-bank holiday Saturdays if the noise level of the work is a maximum of 35dB in nearby residences

The construction phase of the West Metro’s Matinkylä–Kivenlahti section is scheduled for 2019–2021. The building phase will include five stations, the track and the Sammalvuori depot, 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. In 2023, the stations and rail line will be handed over to the operator, i.e. HKL, in order to begin running passenger traffic.

More information about the Soukka construction will be given on Tuesday, 14 August 2018 at 5.307.30pm at Soukan palvelutalo (address Soukankaari 7). Welcome!

Building of metro stations and the track commencing – special expertise in different fields required

Phase two of the West Metro, that is, from Matinkylä to Kivenlahti, is moving on from excavation to construction. Competitive tendering will be completed this year to find contractors for each station. Contractors with project management responsibility have already been chosen for Soukka and Kivenlahti stations. Soukka station will be built by the YIT Rakennus Oy and Are Oy consortium, and Kivenlahti station by Skanska Infra Oy. The Matinkylä to Kivenlahti railway sections will be built by Graniittirakennus Kallio Oy. The procurement notices of the remaining three stations have been published, and contractors for all the stations will be chosen by October. The Sammalvuori depot has already reached the roof wetting stage. The work consists of not only building the stations, but 24 subcontracts will also be tendered out.

The West Metro consists of 52 different technical systems. Construction requires plenty of special expertise in different fields. The images on the website show the tunnel is built and in which order the metro station systems are completed.

The construction work will continue until 2022, after which the project will proceed to the commissioning phase. The goal is that the seven-kilometre rail line together with its five stations and depot will be handed over to the operator, HKL, during 2023. The lesson learnt from the first phase is to set aside enough time for the commissioning phase, joint use tests, other testing and official inspections. Construction will end once the stations and railway sections are handed over to the operator HKL to commence traffic services.

In March 2018, the City of Espoo reviewed its project plan from 2012 for the second phase. The revised cost estimate for the entire project is EUR 1.159 billion.

Skanska to build the Kivenlahti station

Skanska Infra Oy has won the construction contract for the Kivenlahti station on the Matinkylä–Kivenlahti section of the West Metro. The total contract price is EUR 51 million.

The project will include the construction of the Kivenlahti metro station, a service tunnel and entrances from Kivenlahdentie and Kivenlahdentori. The construction area is about 22,000 square metres, and some 13,000 cubic metres of concrete will be poured. The Kivenlahti station will be the terminal station of the second phase.

“It is wonderful to be part of a project where we get to construct a metro station with a familiar client by utilising competencies from different Skanska business units. We have completed several excavation and construction projects for Länsimetro, and, in the construction of the Kivenlahti station, we can fully utilise our experience in challenging underground construction,” says Pekka Räsänen, regional manager at Skanska Infra.

During the year 2018, the project will progress from excavations to construction.

“The construction of the second phase is on schedule. The contractors for the Soukka station and rail line have been selected, and the construction work on the Sammalvuori metro depot has proceeded to roof wetting. The tenders for the construction of the three other stations have been published, and the contractors will be selected by October,” shares Ville Saksi, CEO of Länsimetro Oy.

In addition to building the stations, 24 subcontracts will be tendered out. The construction work will continue until 2022, after which the project will proceed to the commissioning phase. The goal is that the seven-kilometre rail line together with its five stations and depot will be handed over to the operator, HKL, during 2023.

In March 2018, the City of Espoo reviewed its project plan from 2012 for the second phase. The revised cost estimate for the entire project is EUR 1.159 million.

Mesvac to supply fire sliding doors and fire roller shutter doors for the second phase

Mesvac Oy was chosen as the supplier of fire sliding doors and fire roller shutter doors for the Matinkylä–Kivenlahti section. The total price for the fire sliding doors is EUR 2.4 million and for the fire roller shutter doors, EUR 2.7 million.

The West Metro is built to be one of the safest metro lines in the world. The safety of the metro in emergency situations is ensured, for instance, through the use of fire compartmentation, roof screens, a fire detection system, a video surveillance system and a public address system for emergencies. Furthermore, in order to successfully handle emergency situations, tested fire sliding doors and fire roller shutters are needed for compartmentation and for protection from the spread of fire. 45 fire sliding doors and 33 fire roller shutter doors will be installed for the section. The work includes both door installation and testing.

“The tendering of fire sliding doors and fire roller shutters is a part of the procurement for subcontracts. The project includes a total of 24 subcontracts. “Both door types are required to have a fire resistance class of EI 120 and a pressure resistance of 1.3 kN/m2,” states Raimo Kaunismäki, Technical Director at Länsimetro Oy.

Door installation work will begin in summer 2019.

“When you are responsible for the safety of thousands of passengers, there is no room for compromise. “We have tested products, special expertise and decades of experience in underground construction,” shares Kent Silvan, Managing Director at Mesvac Oy, a company that has been operating for more than 40 years.

The revised cost estimate for the entire project is EUR 1.159 million. The goal is that the seven-kilometre rail line together with its five stations and depot will be handed over to the operator, HKL, during 2023.
