We used product engineering principles to tackle the problem. We divided both the revolving, ring-shaped frame that bears the restaurant floor and the permanent support structure into segments. This created a modular system, which is also very affordable thanks to its repetitive character. It’s a familiar approach for our experienced engineers: “Although this project stands out from the rest of our engineering portfolio, in reality only the scale level is bigger than what we’re used to,” reveals engineer Ingmar Maurice. Together with trusted partner VDL, we worked out the idea in detail and then produced and installed it in the tower.
