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 of the Riilahdentie entrance to the Matinkylä-Kivenlahti section of the Länsimetro were begun at the Kaitaa work site on week 47. The Riilahdentie shaft is one of the technical shafts of the Kaitaa contract section. Once the metro is completed, these shafts serve as emergency exit, smoke extraction, pressure equalisation and ventilation shafts.

Excavations begun with boring work that will continue for an estimated two weeks. The boring work is followed by blasting work for another estimated two weeks, with the shaft excavation expected to be completed before Christmas.

Both boring and drilling work takes place on weekdays between 7 a.m. and 6 p.m.

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 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.

Work at the Espoonlahti worksite also continues at the station, at the Espoonlahdentori entrance and the Opettajantie shaft. The status of the entire worksite is described on the Espoonlahti worksite page.

Mikko Mauro begun work as a fire safety expert in the West Metro project on 25 October. In addition to supervising fire engineering, Mauro will focus on managing fire safety as a whole in the planning, construction and introduction phases of the project.

Mauro transferred to the West Metro from L2 Fire Safety Ltd. He previously worked at L2 as a fire engineer in the West Metro’s Ruohonlahti-Matinkylä phase, so the West Metro is a familiar project for him.

Mauro also has practical experience in rescue work – before his career as a fire engineer, he worked as a fireman. He also holds a Master’s degree in education from the University of Helsinki.

“The metro offers interesting challenges in a professional sense. We are implementing a good, high-quality public transport solution that will serve society in an extensive way”, Mauro says.

 

A status report on HKL’s introduction of the Ruohonlahti-Matinkylä section was presented to the Board.

The Managing Director was authorised to begin preparations for the procurement of the construction projects of phase two, the Matinkylä-Kivenlahti section.

The Chief Financial Officer of Länsimetro Oy presented the company’s financial situation to the Board. The Managing Director was authorised to begin a tendering exercise and enter into a contract with respect to a maximum of EUR 50 million of financing for the second phase of the Matinkylä-Kivenlahti line.

The company’s measures to develop internal communications in the project organisation for the second phase were presented to the Board.
