The standby generators for West Metro will be supplied by TYL Geneset Powerplants. The value of the contract is about EUR 1.4 million. The standby generators are generators driven by diesel engines. These will be located in designated facilities at all stations to ensure an uninterrupted power supply to critical systems in case of a disruption in the power grid.

The gas suppression system for West Metro will be supplied by Mako Oy. The gas suppression system contract includes fire extinguishing systems for all telecommunications and automation rooms on the West Metro line where traditional sprinklers cannot be used. The value of the contract is about EUR 415,000.

– There are a few contracts left to sign for the West Metro project this year and next year. Excavations are now 99% complete. In the construction projects, retaining wall elements have been installed over a stretch of six kilometres by this time. Construction is proceeding in parallel in the metro tunnels and at four stations, and soon all stations will be under construction. At that time, the project will be employing more than 1,000 people, according to Matti Kokkinen, CEO of Länsimetro Oy.

Länsimetro Oy is a company jointly owned by the Cities of Espoo and Helsinki, tasked with building the West Metro underground line from Ruoholahti to Matinkylä. The aim is for metro traffic to start on the new metro line at the end of 2015. The company was established in 2007. The Länsimetro offices are situated in Tapiola, Espoo.

Agreements for the electrical, HVAC and structure-borne sound insulation contracts for Länsimetro’s station in Tapiola signed 9 September 2103. ARE Oy was chosen as the station’s electrical contractor. The total contract price is EUR 3.4 million. The Tapiola station’s HVAC contract was awarded to EMC Talotekniikka Oy. This contract is worth EUR 3.6 million.

An agreement for the delivery of structure-borne sound insulation materials for the west metro was also signed today. The project’s insulation material contracts have been divided into separate deliveries according to insulation class. The delivery contract for insulation class 16 dB was awarded to Christian Berner Oy. The total contract price is approximately EUR 230.000. The 16 dB material will mostly be used for rail junctions near stations and close to the surface. The structure-borne sound insulation material will be installed under the metro tracks to prevent vibration and noise from being transmitted to the surrounding rock and thereby to the immediate environment. The use of insulation materials is based on calculations performed in vibration and sound-engineering studies.

– “Most of the contracts involved in the construction project have now been awarded. The excavation work for the line will be completed by the end of the year, allowing construction to begin along the entire length of the line. The West Metro project is a major employer, and the line’s completion will require a total of 4,900 person years”, says Länsimetro CEO Matti Kokkinen.

Skanska Infra Oy and Länsimetro Oy have signed the agreement awarding the construction contract for the Keilaniemi metro station in Espoo to Skanska. The total contract price is about EUR 37.5 million.

The contract covers the construction of the station hall and overground entrances to the Keilaniemi metro station, the access tunnel, technical facilities and the outfitting of the Karhusaari tunnel. Construction work has already begun, and the station is scheduled for completion in November 2015.

Constructing the Keilaniemi metro station will require 14,000 cubic metres of concrete, 1,200 tonnes of iron rebar and 55,000 square metres of planking, among other things.

“Keilaniemi station is located in the very centre of the most significant business cluster in Espoo. We are pleased to have such a high-quality contractor working on this station. We are nearing the end of excavation and moving to the construction stage, and the project is progressing smoothly,” says Matti Kokkinen, CEO of Länsimetro Oy.

Lemminkäinen Infra Oy will begin open excavation in the pit at the Urheilupuisto station worksite during week 22. According a decision issued by the Uusimaa Centre for Economic Development, Transport and the Environment, blasting work in open excavation may be carried out on weekdays (Monday to Friday) between 07.00 and 22.00, and also on Saturdays that are not public holidays between 07.00 and 22.00. Blasting in open excavation will be announced by an audible warning signal.

Drilling and scaling work, rock shattering with jackhammers, and other work causing noise and vibration will be restricted to between 07.00 and 18.00 on weekdays, although such work will also be undertaken between 18.00 and 22.00 on weekdays and Saturdays that are not public holidays as the environmental permit allows. Work done in the evening and on Saturdays makes overall progress quicker.

Other preparatory tasks in the worksite pit are being done on a 24/7 basis.

No noise-generating work will be done on 1 June, the day of end-of-school celebrations.

Excavation and reinforcement work in the station worksite pit will continue until the end of 2013.

Reinforcement work is currently in progress at the Urheilupuisto station site, and open excavation will begin in the pit in mid-May. The excavation work will continue until the end of 2013. The pedestrian and cycle path to the south of Esport Center will remain closed for the time being because of the open excavation and other construction work.

Unlike the other stations on the West Metro line, the Urheilupuisto station is being built on the cut-and-cover principle. Because of this, the pedestrian and cycle path to the south of Esport Center has been diverted to the north side. The original aim was to reopen the path while the work is still in progress, but this has been abandoned for the time being for safety reasons.

We regret the inconvenience caused to local residents by the worksite.
