Board of Länsimetro Oy, summary of decisions – 22 January 2018

The Board was presented the situation on the final financial statement of the first phase of the West Metro, the Ruoholahti-Matinkylä section. The final financial statements are currently being prepared. Incomplete construction projects for the first phase still include the southern entrance in Tapiola and the western entrance in Matinkylä. The construction of both entrances is tied to the schedules of other ongoing construction projects in their respective areas. In Tapiola, the entrance is situated below the currently developed Ainoa 3, and in Matinkylä, it is built in connection with the upcoming hotel in the so-called Tynnyripuisto area.

Status updates on the maintenance and servicing of the first phase of the West Metro, the Ruoholahti-Matinkylä section, were presented to the Board. Länsimetro Oy handed over the stations and rail to HKL for the initiation of traffic on 3 October 2017. The rail, its technical systems and the eight stations remained 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.

The incentive scheme for the second phase of the West Metro, the Matinkylä-Kivenlahti section, was presented to the Board.

The Board received a status update on the risk management of the second phase.

The next meeting will be held on 28 February.

Technical management expert with experience from HKL and VR joins West Metro as maintenance manager

Janina Lempinen (B. Eng. in automation engineering) joined the West Metro project on 8 January 2018 as a maintenance manager.

Lempinen supervises repairs and maintenance of the rail and stations of the first phase of the West Metro from Ruoholahti to Matinkylä. The rail and stations were handed over to HKL on 3 October 2017 as part of their opening for traffic, but the eight stations and the rail line with its technical systems remained in the ownership of Länsimetro Oy.

Lempinen’s responsibilities include the monitoring of maintenance of the stations and technical systems and the development of these in cooperation with HKL.

Lempinen joined the West Metro project from HKL, where she worked as a technical depot manager. She also has experience of working as a building services engineering expert and technical manager with VR Group until 2015. She is therefore familiar with a variety of operating environments and properties related to rail traffic.

“The West Metro presented an exciting opportunity for both my career and personal development. The West Metro systems are more modern and technically advanced than those found in the older section of the metro line, and provide an opportunity to learn about challenging and complex overall systems”, Lempinen says.

In her first days in her new position, Lempinen is reviewing various contracts and visiting the metro stations in person.

 

New HVAC supervisor at Kivenlahti station – a veteran of the first phase

Tarja Nieminen (B. Eng) began work with the West Metro project on 2 January 2018 as a HVAC supervisor. In her work, Nieminen focuses on supervising HVAC work on the Kivenlahti station construction site.

The construction of metro HVAC systems is familiar to Nieminen from the first phase of the West Metro, during which she was employed by Caverion Suomi Oy as an air conditioning project manager at the Keilaniemi station site for 18 months.

“The HVAC and cooling systems used in the second phase of the West Metro are similar to those of the first phase. I am particularly familiar with the initial construction stages of metro stations”, Nieminen says.

In addition to Caverion, Nieminen has experience of HVAC supervision and project management with firms such as Sweco Asiantuntijapalvelut Oy, Karves Energia & Valvonta Oy and Sähköpeko Oy.

“I have experience of HVAC supervision in building renovation projects, and the West Metro is an exciting next step in my career”, Nieminen says.

For Nieminen, the technical building services of metro stations and a large shopping centre have much in common. At a metro station, the systems are simply implemented underground.

“When building a metro station, the space required by technical systems and the underground environment pose unique challenges. I am starting my work by studying the plans and contracts related to the station’s construction”, says Nieminen.

First and second phase tunnels linked – breakthrough between Matinkylä and Finnoo

The first and second phase tunnels of the West Metro were linked for the first time on Wednesday, 29 November, as a breakthrough was made in the southern rail tunnel, between the completed Matinkylä rail tunnel and the Finnoo tunnel under excavation. The northern rail tunnel will be connected during week 49.

In each West Metro contract, the worksites excavate simultaneous tunnels which are then connected at the boundary between contract areas. At the Matinkylä–Finnoo section, the tunnels were separated by on average a three-metre layer of rock that was removed for the breakthrough.

The breakthrough was carried out so as to not cause disturbance to the operational metro traffic. The breakthrough between the tunnels took place at a distance of some 500 meters from the station. The explosion force was also suppressed by a pressure wall and excavation bank.

After the Matinkylä–Finnoo section, only the Espoonlahti–Kivenlahti section remains unconnected, with the breakthrough between them planned to be carried out in mid-December.

A total of 93.4% of the excavations for the West Metro’s Matinkylä–Kivenlahti section are now completed. Five new metro stations are constructed for the second phase west of Matinkylä: Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti. In addition, an underground metro depot will be constructed in Sammalvuori.

Excavation at the Suomenlahdentie shaft from 20 November

Shaft excavation will begin at the Suomenlahdentie shaft at the West Metro Finnoo worksite in week 47, from 20 November. Excavation will mainly involve tunnel excavation, as the shaft will be excavated upwards from the tunnel to the ground level. The last blasting at the ground level will involve open excavation.

The blasting work will last about three weeks, followed by reinforcement work and making of the concrete structures. All in all, work on the shaft is expected to be completed in March 2018.

The tunnel excavation will be performed from Monday to Friday between 7 am and 10 pm. The last blasting operation, to be performed as an open excavation, will comply with the working hours specified for open excavation (Mon-Fri 7 am to 6 pm).

What are the shafts? You can find more information on shafts here.

Excavation at the Maininkitie shaft from 20 November

Excavation of the Maininkitie shaft will begin at the West Metro Espoonlahti worksite on week 47, from 20 November. The Maininkitie shaft is one of the technical shafts of the Espoonlahti contract section. Once the metro is completed, these shafts serve as emergency exit, smoke extraction, pressure equalisation and ventilation shafts.

Excavation of the shaft will begin with drilling of the excavation holes, and blasting work is set to commence after that. The excavation work, which will take approximately three weeks, will be performed on weekdays (Mon-Fri) between 7 am and 6 pm.  The working hours are based on a noise permit by Espoo Environment Centre.
