CBE Group provided 3 carousels to the Acciona-Ghella joint-venture, mandated for the construction of the 22 km long double tunnel, linking Oslo, capital city of Norway, to Ski. The 3 carousels, as well as the moulds, were designed in the design office in Saint-Avertin, France. CBE Group took care of the production, installation and the launch of the 3 carousels.
It’s a first for CBE Group, which had never provided 3 carousels and 3 pre-storage carousels for a single precasting site, one more proof of CBE Group's know-how. The company also provided 144 moulds for a total of 18 concrete rings.
The construction of the double tunnel officially begun in 2015, 4 TBMs are currently at work. The whole project should be completed in 2020/2021.
