Basic information
Project characteristics
This is a project containing excavation of new tunnel and building of new road to village of Fámjin on the southernmost island of the Faroe Islands. Metrostav Norge as a subcontractor provided excavation, reinforcement of the tunnel and water and frost protection works.
Tunnel with the length of 1 200 m was excavated from one direction from portal above Øravík village. Profile of the tunnel is T8,5, ca 65 m2 with two safety bays.
Before the excavation started, it was necessary to build up construction site on the greenfield, including temporary reservoir for technological water.
The biggest challenges were not only complicated geological composition, but also harsh climate conditions with wind gusts reaching up to speed of 200 kph.
