Al Fattan Office Tower, Dubai, UAE
VARIO GT 24 solution to adapt the formwork to unusual corewall shape
The owner of the Al Fattan Towers, completed in 2006, decided to build an office tower as well, which is located directly in front of the existing twin towers and connects the buildings. The office tower, which is under construction at the moment, is going to be a multistorey building with 2 basement levels and 13 floors. Sungwon was appointed as contractor for this project and they decided to use PERI as the technical solution and support that was offered for this complicated structure was very important for ensuring good performance by the contractor.
As the core wall has a special shape, it couldn’t be formed in a common way. PERI’s technical department found a solution in using the VARIO GT 24 formwork to form the curved core wall and climbing it with the CB 240 Climbing Platform, as well as having internal shaft platforms. As the core wall is curved, a special solution for the internal shaft had to be designed as well. The core wall area spans over 715 m² and requires a formwork height of 4.20 m. The second tricky part in the core wall is that there are small shafts in it, which also need to be covered.
VARIO GT 24 is used to form the columns as the system is flexible enough to also form the racking columns, which are inclined by 15°. The slabs of the typical floors, which are done by using the PERI Tableforms, cover an area of approx. 2,000 m². To support the slab in the 5th floor PD 8 had to be used in some areas, as for architectural reasons there is an opening from the ground floor upwards. In those areas the height of the PD 8 towers is 20 m.

“We chose to use PERI as we know it as the best and safest formwork system. We know that PERI has qua-lified engineers to support us imme-diately and in a co-operative way. At the Al Fattan Office Tower we have to install the 25 m high slab, for which PERI gave us a very easy and fast system solution. If you ask us “Do you want to use PERI again for the next project?”, then I will say “Absolutely”.”
