The west metro project has a tailor-made monitoring system that can be used by residents to monitor the progress of work in the project. The service displays a map of the entire metro line, stations, shaft building and service tunnels with up-to-date information on how far the ends of the tunnels reach at any given time. To monitor the progress of the work, you should go to the map where you can see how the excavation work is progressing. You may even enter your address to see how far from your home the end of the tunnel is located.

The system also allows the monitoring of groundwater, vibration and ground subsidence observation points and the recording of the observation data, which are utilised and monitored by Länsimetro Oy, consultants and constructors involved in the project, and various authorities.
