Lemminkäinen Infra Oy will begin open excavation in the pit at the Urheilupuisto station worksite during week 22. According a decision issued by the Uusimaa Centre for Economic Development, Transport and the Environment, blasting work in open excavation may be carried out on weekdays (Monday to Friday) between 07.00 and 22.00, and also on Saturdays that are not public holidays between 07.00 and 22.00. Blasting in open excavation will be announced by an audible warning signal.
Drilling and scaling work, rock shattering with jackhammers, and other work causing noise and vibration will be restricted to between 07.00 and 18.00 on weekdays, although such work will also be undertaken between 18.00 and 22.00 on weekdays and Saturdays that are not public holidays as the environmental permit allows. Work done in the evening and on Saturdays makes overall progress quicker.
Other preparatory tasks in the worksite pit are being done on a 24/7 basis.
No noise-generating work will be done on 1 June, the day of end-of-school celebrations.
Excavation and reinforcement work in the station worksite pit will continue until the end of 2013.
