Two climbing systems on the core reduce the crane requirements and keep the costs down
With a total height of 300 m this new skyscraper in the centre of Riyadh will be the tallest building in Saudi Arabia. It was clear for the client that with this difficult project the available crane capacity would be decisive and that successful completion would be dependent on the formwork concept.
PERI presented a combination of two climbing systems on the 34 storey core which reduced the available crane capacity and, at the same time, kept the budget for the whole formwork costs within reason. 432 m² of VARIO wall formwork climbed independently of the crane on 22 ACS-R platforms on the outside of the core. The internal walls were formed with VARIO on CB 240 brackets. Formwork and climbing scaffolds formed a single unit that could be moved by the crane, thus saving time.
In the following floors two UNIPORTAL table sizes (5.00 x 3.00 m and 5.40 x 2.70m) and optimum beam tables for the building (principally 3.30 x 2.10 m) completed the total economical concept.
The site were able to easily complete the building, floor to floor, in a regular four-day cycle.
