Every week one storey higher with ACS and RCS
The floorplan for this impressive building complex tapers gradually in four steps as it rises majestically in the air: at heights of 65 m, 121 m, 201 m and 338 m. With the PERI formwork and scaffolding solution, these ground plan changes could be accomplished without any time-consuming and costly modifi cations.
The biggest challenge consisted of continuously finishing a complete storey on a weekly basis. This ambitious plan could only be realised with fast and safe systems combined with high levels of material usage. Therefore, over 16,900 MULTIPROP aluminium post shores and 2,600 PEP steel props were needed at the same time for the shoring alone on the lower levels. Using PERI SKYDECK with the drophead system meant that the slabs could be struck after only two days.
The massive reinforced concrete columns on the north and south sides were constructed with the ACS climbing system and the VARIO girder wall formwork which freed up valuable crane time. At the same time, the ACS platforms also functioned as protection against falling on slab edges. PERI engineers developed customized climbing units for the column and climbing rail spacings of 9.10 m.
From the 16th fl oor onwards, the east and west sides were cladded with the RCS climbing protection panel. In so doing, the building edges of the upper storeys were completely enclosed and moving the slab formwork could be accelerated. Equipped in part with mobile self-climbing devices, the RCS could be climbed crane-independently.

“All the systems on site are easy to use and adapt quickly to the changing conditions of this large project. The engineering and logistical support we receive from PERI is important to our success.”
