Our working hours are weekdays at 7-22, when we drill, blast and perform other work on the site. Silent work (below 30 dBA) may also occur at other times. In cases where night work is in progress, it takes place completely inside the tunnel and should not disturb the surroundings.
Transports to and from the site normally take place until 19.00. As far as possible, drivers avoid rush hour traffic.
The Swedish Environmental Protection Agency has guidelines (NFS 2004: 15) for how much disturbing noise it may come from construction sites, and we follow these when we build the sewer tunnel. If you are affected by disturbing noise over the Swedish Environmental Protection Agency's guidelines, you can, if necessary, have access to a replacement home.

When the tunnel is completed, the area will be restored in consultation with the landowner.
Sometimes an air shock is heard like a sharp bang, and for others it is felt more like a rumble and vibrations from the ground. We blast up up to twice a day at each tunnel front.
When we blast, we adapt the intensity of the blasting to the surroundings and we have meters set up in several places around the area where we measure vibrations and air shocks to see that we do not exceed any guideline values.
You can receive notifications via text message about 30 minutes before we blast in the sewer tunnel.

We will need to remove rock spoil from the site during the construction period, which means that trucks will be driving to and from the establishment zone. The Land and Environment Court does not permit heavy goods vehicles to use Hägerstens allé, so an enclosed temporary transport route will be constructed on the footpath south of the work site to Selmedalsvägen. From there, transport will continue via Personnevägen and out onto the E4/E20.

A "transport movement" is a one-way truck journey.
