Blasting outside the normal time range at the Soukka access tunnel on 23 March

At the Soukka access tunnel, blasting work on the tunnel end wall had to be carried out on Monday 23 March 2015 at 22:10, at an hour outside the normal time range for blasting work. Blasting in a tunnel is allowed between 07.00–22.00 (Mon–Fri) According to the contractor, the tunnel had been charged for blasting but, due to the heavily fractured nature of the rock, the crew was unable to to blast the end wall of the tunnel before 22:00. As postponing the blasting of the end wall, which was charged with explosives, until the next morning was out of question, the job was completed outside normal hours.

We apologise for any inconvenience due to the exceptional blasting time.
