Central Market, Abu Dhabi, UAE
Technical know how and a mix of PERI systems lead to a successful progress
The Central Market Site has a great history: For over 40 years the original souk, which was known as a hub of trade and meeting point, was located there. The new Central Market was designed in such a way that this spirit can actually go on. The project consists of four highrise buildings. There will be one tower with more than 72,000 m² office space, another tower will accommodate more than 450 appartments. A five and a fourstar hotel will be located in the central market, as well as a retail podium with many shops. There will be more than 5,000 parking spaces and a shopping mall. Tower 2 as the major project will be the tallest tower in Abu Dhabi City with 90 floors and a height of 374 m. It requires very intensive cooperation between PERI‘s technical department and the contractor to find economical technical solutions for the different areas and to achieve the intended floor cycle of 5 days.
The slab heights in this project vary from 3 m to more than 20 m and the slab thicknesses differ as well. Therefore, the technical department decided in cooperation with the contractor to use a combination of MULTIFLEX, PD 8 and Tableforms so that the different requirements in the slabs could be fulfilled.
To ensure the required floor cycle time of 5 days is achieved, the shear walls were formed using the VARIO system in combination with the ACS Climbing system. By doing this, a lot of crane time is saved as no crane is needed to get the formwork from floor to floor 90 times.
Special requirements in the podium areas lead to the use of the PD 8 system to support the high slabs and SKS for the climbing of the singlesided walls. With the SKS 180 climbing system, the loads from the fresh concrete pressure are transferred through the brackets by means of V-strongbacks and compression braces into the scaffold anchors. Generous bracket spacings allow large area formwork units with optimal utilisation of the bearing capacity. This leads to an extremely economical solution.
The shear walls in Tower 3 are formed with TRIO as fewer individual components are needed which leads to faster forming. VARIO GT 24 is used in several areas of the project. In some areas with the GT 24 girder and other areas using the VT girder. It is used for retaining walls, shear walls, small core walls and belt walls. The VARIO Column formwork is used in the podium, as well as in the towers.
In the technical floors of the tower and in some parts of the podium area the CB Climbing is used. The CB 240 and CB 160 climbing scaffold systems are framework brackets for supporting large area wall formwork. They guarantee simple handling, fast concreting cycles and problemfree adjustment to different wall configurations.
As this project needs good technical support and a reliable material supply – PERI was chosen to deliver the mix of the formwork solutions for the different areas. As the towers are very high the safety of the systems was also a reason for the contractor to choose PERI.
