Construction of the Kivenlahti access tunnel will begin in December. Earthwork will first be carried out at the worksite (sheeting of the open excavation, injection piling and earth removal). Open excavation will begin in March 2015. Blasting for open excavation will be announced by an audible warning signal that is broken before the blast and continuous afterwards. After open excavation, the work will continue underground with building the tunnel in around April 2015. The excavation work for the access tunnel will continue until October 2015.
After the access tunnel project, a metro tunnel and metro station site will be excavated. During both work phases, excavated rock will be taken to Länsiväylä and further afield for use in other construction projects. Haulage will be based on the blasting times. Blasting will occur 1–3 times a day.

Earthwork and excavation work
