On the night of 15 to 16 December, a gigantic crane with a boom of 70 meters has been erected on the installation place below the Thuner landmark by the "ARGE Marti Schlossberg", consisting of the Marti Tunneling AG, the Marti Generalunternehmung AG and Marti AG Bern.
With this crane, the excavated material of the vertical shaft on the Schlossberg will be transported away. The crane will also be used to move the materials on the installation site and to ensure the supply of materials for underground concrete structures.
With the lift and stairs in this vertical shaft, the car park and the Schlossberg will be accessible for the user. The construction of this new column-free car parking garage with 300 parking lots will be completed in the summer of 2018.
