Koivusaari metro station to open for passengers on 6 August

The refurbishment of the Koivusaari metro station’s floor has been completed and the metro station will be re-opened to passengers on 6 August. The station will be opened when morning traffic commences. The first train from Koivusaari will leave the station in the direction of Vuosaari at 5:21 a.m. on 6 August. The timetables of all of the metro trains running from Koivusaari are already available on HSL’s Reittiopas service, alongside the other timetables.

The floor refurbishment was carried out at the station due to cracks detected in the platform area’s floor surface material. The floor refurbishment project proceeded according to schedule. In June, the old flooring was removed, while ensuring that metro traffic could continue amidst the dusty demolition work. After Midsummer, the installation of the new flooring was begun in the platform area. In conjunction with the installation, photoluminescent strip indicators used in the West Metro were installed at the station to assist visually impaired people. The work was completed at the end of July.

Situation management model keeps West Metro on schedule

Construction of the West Metro’s Matinkylä–Kivenlahti section is underway at all five stations and the rail section. The construction of the Sammalvuori depot has progressed to the testing phase. The schedule and costs of Finland’s largest automation, HVAC and electricity and infrastructure project are monitored in the project’s war room. The project is progressing in line with the project plan’s schedule and budget.

The nerve centre of the situation management model is the war room, which produces real-time information on the various construction areas. The project’s schedule, costs, risks, quality, smoothness of co-operation and occupational safety are monitored from the war room.

In terms of space, the construction of just one modern West Metro station is the equivalent of building a mid-sized shopping centre underground. The project involves a number of players – the developer, designers and engineers, equipment suppliers, contractors, subcontractors and authorities – who must all stick to the same schedule and pull together.

Data is supplied to the war room by contractors and West Metro’s worksite supervision. It is important not to manage the project based on information obtained from a single source; integrated situational information compiled from a number of sources helps create an overall picture of the project. The quality of the situational information has also been a focus area. The war room processes and refines recent and accurate information that is verified by several sources.

“In terms of schedule, we monitor, for example, the schedule announced by the project management contractor and the progress of the sub-contracts at each of the stations. The monitoring of the schedule is supported by cost monitoring based on several sources and West Metro’s own worksite supervision. In addition, we monitor the progress of the work through worksite visits and documentation,” says Ville Saksi, CEO of Länsimetro Oy.

Without the situation management model, monitoring such a large project and ensuring that it is kept on schedule and on budget would be a daunting task. The model was especially designed for managing a large project such as the West Metro based on the experiences gained during Phase I of Länsimetro’s project. The project is responsible for monitoring and ensuring that each contract and job is completed on time.

“Situation management means management through data, in which we are forerunners. With the help of the model, we are able to react to issues, quality problems and schedule challenges before they pose a threat to the entire project’s targets. It all comes down to proactively promoting work and addressing problems in time,” Saksi continues.

2020 will be an intense year of construction for the Matinkylä–Kivenlahti metro section. The focus of construction shifted in the spring from structural work to surfaces and interiors, HVAC and electricity and automation installations. On Länsimetro’s part, the construction will end with the simultaneous handover of all five stations and the 16.5-kilometre rail section to the metro operator in 2023.

Summary of Länsimetro’s meeting of the Board of Directors on 18 June 2020

The Board of Directors approved the proposal concerning the transport of rails related to the West Metro superstructures contract via the metro. The rails of the Matinkylä-Kivenlahti section will be transported from Vuosaari through the section in operation to be installed in Matinkylä. As the rails are 120 m long, the only way to get them to the rail section is to transport them at night through the metro in operation.

The Board of Directors approved the proposal concerning the feeder points for bikes to be implemented in connection with the Espoonlahti station.

The Board of Directors approved the framework bidding for expert services. The framework bidding was carried out in the form of public procurement.

The Board of Directors approved the review of the contents and the ceiling price of the construction management services for the Matinkylä-Kivenlahti section.

A status report on the construction and cost monitoring of the Matinkylä–Kivenlahti section was presented to the Board through a view of the war room. Construction is progressing in line with the project plan’s schedule and budget.

The status of the commissioning planning for the Matinkylä-Kivenlahti section was presented to the Board. The commissioning planning is proceeding on schedule.

The next meeting of the Board of Directors will be held on 27 August 2020.

Floor renovation at the Koivusaari metro station is progressing as planned

Work to renew the floor surfaces at the Koivusaari metro station began on 1 June 2020. The demolition of the floor was completed before Midsummer, except for some finishing touches. The floor renovation has been proceeding on schedule. Some of the foundation work for the floor structures has been carried out simultaneously with the demolition work. The foundation work continued over Midsummer, and the work of the subsequent weeks will sync with the new mosaic concrete tiling work. The worksite area has been cordoned off from the metro traffic, and the metro traffic passing through the station is unaffected. The work will not cause major disturbances to the neighbourhood.

By Midsummer, most of the mosaic concrete floor of the platform level was demolished. The work continued after Midsummer with foundation work for the floor structures, after which the installation of the new floor tiles will begin.

 

The installation of the new floor tiles will begin at the end of June. The tiles will arrive at the Koivusaari metro station this week. After the installation of the tiles, the necessary final touches, final cleaning and dismantling of the worksite will be carried out, and the station will be ready to open to commuter traffic in August.

The floor renovation work will continue at the Koivusaari station until 5 August.

Länsimetro Oy is renovating the Koivusaari metro station’s floor surface at the platform level in summer 2020 due to cracks in the mosaic concrete. The floor renovation will be carried out by SRV Rakennus Oy. While the floor surface is being re-laid, from 1 June until 5 August 2020, the Koivusaari station will be closed. This means that metro cars will not stop at the station, and the station’s entrance will be closed.  Information about the progress of the Koivusaari metro station’s floor renovation will be provided on the Koivusaari station’s web pages.

First rails for phase II of West Metro project to be installed in summer

The superstructures contract for the rails of the Matinkylä–Kivenlahti section of the West Metro project has begun. The contract covers the laying of ballast, and the installation of cable ducts, sleepers, rails and the conductor rail. Once this work is completed, test runs of the metro train will be conducted on the new section in summer 2021. The first rails have already arrived at Matinkylä and are awaiting installation.

2020 will be an intense year of construction for the Matinkylä–Kivenlahti metro section. The focus of construction shifted in the spring from structural work to surfaces and interiors, HVAC and electricity and automation installations. All five metro stations as well as the rail line have several contracts under way and an increasing number of operators working on them. The Sammalvuori depot has already progressed to the testing phase. The depot will be completed this year. Overall, the project is proceeding in line with the project plan’s schedule and budget.

“The superstructures contract for the rail tunnels will begin with the laying of sub-ballast. The total length of the rail tunnel is 17.5 kilometres. The ballast will be brought into the tunnel in dump trucks: one load of ballast will cover approximately five metres of track. Noise insulation will be installed underneath the layer of ballast in both tunnels to ensure that structure-borne noise does not carry to the buildings above,” says Juha-Matti Pakka, supervisor of the rail engineering contracts on the West Metro project.

The next stage will see the switches installed in the tunnel; these will be measured and adjusted multiple times during the contract. Retaining wall elements, the top of which serves as an emergency exit route and the inside of which contains the technology required for a modern metro system, have already been installed in the tunnels as part of an earlier contract. The retaining wall’s cable ducts will be installed in conjunction with the levelling of the ballast.

The next step will be to install the sleepers in the tunnel. The section will have a total of 27,400 sleepers, supplied by Parma’s Forssa factory. The rails to be installed on the sleepers will arrive from Spain and will be welded into 120-metre lengths at Vossloh’s Kaipiainen factory. The rails will be delivered during the night via the Vuosaari harbour, through the current metro line to Matinkylä, and from there to the new section. The rails for the work track are already at Matinkylä, awaiting installation west of Matinkylä.

After the rails are installed, the track ballast will be laid using a ballast spreader that was specially made for the contract. Track ballast is laid in between the sleepers.

“After the track ballast is levelled out, the rail line will be supported and welded into a continuous track. Continuous track welding requires close monitoring and documentation of the rail’s temperature. This will ensure the smoothest and most consistent metro ride for future commuters,” says Pakka.

After the rail installation, a conductor rail will be affixed to the supports on every ninth sleeper. The conductor rail will be switched live in summer 2021, and thereafter test runs can begin.

The target schedule is to hand over the stations and rail line and their technical systems to the metro operator HKL in 2023. Länsimetro Oy will remain the owner and developer of the metro section.

Koivusaari metro station’s floor surfaces to be re-laid starting 1 June – station will be closed from 1 June until 5 August 2020

Länsimetro Oy is renovating the Koivusaari metro station’s floor surface at the platform level in summer 2020 due to cracks in the mosaic concrete. The floor renovation will be carried out by SRV Rakennus Oy. While the floor surface is being re-laid, from 1 June until 5 August 2020, the Koivusaari station will be closed. This means that metro cars will not stop at the station, and the station’s entrance will be closed. Although the cracks do not affect the usability of the station, it was decided that the repairs should be completed as soon as possible. For that reason, in order to ensure that the floor can be completed over as brief a period as possible, the Koivusaari station will be closed while the work is carried out. This also means that disruptions caused by the work site will be concentrated in the summer season, when commuter volumes are the lowest.

The floor renovation will begin with the setting up of the worksite and demolition and protection work. The demolition stage will last roughly four weeks. Some of the foundation work for the floor structures will be carried out simultaneously over a period of four weeks. As the foundation work progresses one area at a time, the installation of new floor tiles and floor markings will be started. Finally, the necessary final touches, final cleaning and dismantling of the worksite will be carried out, and the station will be ready to open to commuter traffic in August.

The floor renovation work will take place in three shifts around the clock. The repair work will be carried out efficiently and safely such that the metro traffic passing through the station will not be disrupted, the activities at the worksite will not cause major disturbances to the neighbourhood, and the duration of the work will be as short as possible. The worksite area has been cordoned off from the metro traffic. Work that causes dust will take place inside a tent. The station’s elevators and entrance lobby will be reserved for the work site personnel during the repair work. In the event of exceptional circumstances, for instance a stop in metro traffic, commuters will be able to exit the station via the Koivusaari station’s emergency exit routes, following the instructions given.

Information about the progress of the Koivusaari metro station’s floor renovation will be provided on the Koivusaari station’s page of the website.The nearby properties will be kept up to date on the progress of the work during the construction period.
