Acciona Ghella Joint Venture and Bane Nor have been nominated for the “major project of the year” at the ITA Tunnelling Awards 2019.
The EPC TBM Follo Line Project is by far the largest Tunnel Boring Machine project in Norway. Four double-shield TBM’s, all of which have been deployed from the same starting point, have been excavating more than 36 km of tunnel in less than two years – ahead of schedule! The excavated material was extracted on an underground conveyor belt along the tunnel until it reached the outside. At the same time, the rear section of the TBM installed the segmented concrete lining rings in the open section of the tunnel. These segments were partially manufactured at our inhouse concrete factory using the nine million tonnes of excavated rock.
The EPC TBM Follo Line project is in competition with 3 other projects from South Korea, China and Hong Kong, China. The ITA Tunneling Awards will take place in November in Miami, USA.
