The isolation drilling phase will begin at the Iivisniemenkallio entrance shaft of Länsimetro’s Kaitaa site on Monday, 7 August.
The isolation drilling phase will take approximately one month. The work will cause noise disturbance to the environment, but the noisiest work will be carried out only in the daytime between 7 a.m. and 6 p.m. The isolation drilling phase will be followed by an excavation phase, which will also take about a month.
Excavation of the Kaitaantie entrance will begin later, in about 1 to 1.5 months, and we will provide separate information on it. Underground lifting-method excavation is currently ongoing under the shaft.
