Core, Slabs and Facade in a 3-Day Cycle
269 m High Apartment Block
The 21st Century Tower with its 53 storeys, approx. 400 apartments and a total height of 269 m, is another constructional highlight along the Sheikh Zayed Road in Dubai.
PERI Dubai was commissioned to provide a formwork solution which enabled the contractors to fulfill the high requirements and also the tight construction schedule.
Using experience from various successful projects in the past, such as the National Bank of Dubai headquarters and the Emirate Tower, PERI engineers developed a clearly defined concept for this ambitious project.
Using ACS self-climbing technology, the VARIO girder wall formwork for the rectangular core climbed crane-independently from storey to storey. CB 240 climbing brackets and VARIO were used for the facades. The facade formwork could be retracted on the brackets for striking and then moved as a unit to the next storey by crane which saved a lot of time. MULTIFLEX slab formwork on PD 8 shoring towers for the slabs of the service and maintenance floor completed the PERI formwork programme used in this successful project.
Thus, the contractors could achieve the planned 3-day cycle for one complete 1,350 m² floor.

“PERI ACS is unbelievably fast and extremely safe. Due to the self-climbing technology, we could save on considerable amounts of crane capacity which is a big advantage on construction sites like this one.”
