Extreme precision due to extra narrow joints
The project includes 585 panels including 193 columns, up to ten metres in length. The joint sizes across the building are consistent with the joints between the panels, as well as the natural stones being only twelve millimetres wide. This demands extreme precision in the assembly. The precast elements are put in place using two tower cranes, a working method that is only made possible due to an intensive collaboration between Hurks Bouw and Byldis.
The facades of the building slope slightly inwards at the bottom and slightly outwards towards the top, thus creating an hourglass silhouette. The complex shape was a challenge that has resulted in over 1000 different stone sizes in the facade. From the third storey upwards, the facades are constructed using precast elements. The principle of M-shaped elements continues from top to bottom. Despite the sloping facades, all the joints between the sheets of natural stone are horizontal.
