Katara Towers
Qatar
Timed to be ready for the 2022 FIFA World Cup, a new luxury hotel complex is emerging on Qatar’s coast: Katara Towers. In addition to hotel rooms, the towers, which are just over 200 m high, will also contain apartments, offices, leisure facilities and restaurants. For erecting the core walls in the towers, climbing formwork systems from Doka were used.
The completed silhouette of Katara Towers, rising from the southernmost point of the 38 km² planned city of Lusail, Qatar, will be a distinctive landmark for the nation. The crescent design of this future “hospitality icon of Qatar” translates the country’s national identity into an architectural landmark. Symbolically intertwined with Qatar’s heritage, the iconic architectural design integrates the traditional scimitar swords from the national seal into a striking pair of symmetrically arched towers rising 36 storeys from the podium level to a height of 211 metres.
Challenge:
The building is structurally divided into five areas and has a total of eight core walls. The central component of the project is the striking pair of symmetrically arched towers 2 & 4. They cover an area of 2,315 m², rise 36 storeys into the sky, and the clear height of the slabs ranges from 4.45 m to 9.15 m.
Solution:
The four core walls 1&2 and 7&8 of the towers are rising upwards with the use of Doka automatic climbing formwork SKE50. For the crane-lifted core walls 3&4 and 5&6, the Climbing formwork 150F and a shaft platform are being used to support the Large-area formwork Top 50.
