For technical reasons, these parts of Valley cannot be put together on the storeys themselves. This is because they protrude too far outside the existing structure. Instead, the Valley Amsterdam construction consortium assembles the steel cubes on the ground. A gigantic crane then hoists them into position. ‘Once up there, we hang them to the bolted joints that have already been fitted into the flooring on each level’, says construction site manager Ruud van der Thiel. When the steel frames are in place, the pouring of the concrete floor can start. As a result, these protruding sections gradually become fused with the existing structure. So far, two of the seven cubes are in position.
