Excavation of the Maininkitie shaft will begin at the West Metro Espoonlahti worksite on week 47, from 20 November. The Maininkitie shaft is one of the technical shafts of the Espoonlahti contract section. Once the metro is completed, these shafts serve as emergency exit, smoke extraction, pressure equalisation and ventilation shafts.
Excavation of the shaft will begin with drilling of the excavation holes, and blasting work is set to commence after that. The excavation work, which will take approximately three weeks, will be performed on weekdays (Mon-Fri) between 7 am and 6 pm. The working hours are based on a noise permit by Espoo Environment Centre.
Work at the Espoonlahti worksite also continues at the station, at the Espoonlahdentori entrance and the Opettajantie shaft. The status of the entire worksite is described on the Espoonlahti worksite page.
