Underground Helsinki accommodates a great many tunnels and other spaces. These should be reviewed before planning any construction project involving excavation. The same applies to drilling.
Areas under construction often have underground cables that have to be removed before construction.
Before undertaking excavation work, the builder shall find out from the cable information service whether there are any active cables, equipment, underground spaces or other underground structures in the area.
Cable information service
The cable information service is available for excavation, drilling and related engineering projects. The service is located at Työpajankatu 8.
