Organisation and decision making

Working in the Big Room

Länsimetro’s 120-expert project organisation works in the shared ‘Big Room’ in Olari, Espoo. The Big Room concept was adopted for the project in June 2017. Länsimetro Oy, its consultants and other persons involved in the project all work under the same roof. The public authorities, city representatives and HKL have been provided with dedicated workstations, which improve the flow of information between the partners.

Communications are direct and fast in the Big Room. Interactive work supports the achievement of common goals, since opinions can be exchanged flexibly and problems solved more quickly.

Decision-making on the project

The highest decision-making body for the West Metro project is the company’s Board. The Board is responsible for the construction of the West Metro and supports the work of the CEO. The Board works on the basis of long-term goals; the focus is on the next 1-2 years of operations. Board members are chosen by the owners, i.e. the cities of Helsinki and Espoo.

Matters are prepared for consideration by the Board by a Steering Group responsible for directing the project. The Steering Group considers issues over a 0.5 to 1 year time span.

The Management Team, which is led by the CEO, maintains a situational picture of the project, sets the general direction of operations and takes major decisions. The focus of the Management Team is 2 to 6 months ahead.

Led by the Project Manager, the Project Team is in charge of daily activities and decision-making on the project, as well as the preparation of decisions. Its tasks also include the coordination and overall management of work. The Project Team looks 0 to 2 months ahead.

A Design Team, a Construction Team and Technical Team work under the Project Team. As their names suggest, the Design Team leads design, the Construction Team manages construction and the Technical Team heads the implementation of technical systems. All of the teams are responsible for the coordination and overall management of tasks belonging to their areas of responsibility.

The site organisation for each station and branch line weighs up the situation at its own site at regular intervals in worksite meetings, planning reviews and project status reviews, for example.


Länsimetro is jointly owned by the City of Helsinki and City of Espoo. The cities have agreed on a mutual distribution of costs along the city limit, using the principle that each party meets the construction costs related to its own area. The costs will be divided so that Espoo’s share is 85 per cent and Helsinki’s share is 15 per cent.

Scope and content of the project

The metro is being built in two phases on the basis of the Länsimetro project. The first section, Ruoholahti-Matinkylä, was handed over to the transport operator, HKL, in October 2017, and passenger traffic began running on 18 November 2017. The Ruoholahti-Matinkylä section covers eight new metro stations; two in Helsinki and six in Espoo. The estimated total cost estimate of Ruoholahti-Matinkylä is EUR 1,186 million. Länsimetro Oy owns the stations and track on the Ruoholahti-Matinkylä section.

The project is being continued with the building of a metro line from Matinkylä to Kivenlahti. The new phase includes the construction of five new stations (Finnoo, Kaitaa, Soukka, Espoonlahti and Kivenlahti) and an underground metro depot in Sammalvuori. The adjusted cost estimate for the construction of phase two is EUR 1,159 million. Read more about the project costs.

The Länsimetro project covers excavationdesign and acquisitions related to the metro tunnels, and the implementation of construction works. See the construction site web pages for further details on progress with construction.


The aim of the project is to build a metro which eases the everyday lives of passengers. A clear route and frequent services will ensure that there is no need to keep glancing at a timetable. The metro is a reliable facility that will take you quickly to your destination. Stations are located in places frequented by people, close to services.

It is intended that the metro investment will pay for itself. As an investment it is profitable, high-quality and durable. Innovative solutions are being sought and construction will stimulate overall economic growth in Finland.

The second phase will be built together. Information must flow in every direction. Good work is being rewarded based on the joint objective of getting the metro ready on time.

The metro is being built responsibly and safely. Occupational safety is an everyday priority and the reliability and safety of the metro is first class, even by international standards. Responsibility also means accountability towards the taxpayer; we need to stick to schedule and budget, and communications must be open and transparent.
