The project will be jointly managed by companies EC Harris and Mace and was designed by the architectural firm Adrian Smith + Gordon Gill.
The building will cost around $1.2 billion to construct and when it is completed, it will be over 150 metres taller than the current tallest building in the world, the Burj Khalifa in Dubai.
The project has identified massive construction challenges that need to be overcome. The building includes 59 proposed lifts travelling at 10 metres per second, but it is yet to be confirmed whether this is indeed possible. Engineers are also testing and developing new methods of pumping wet concrete so far upwards. The challenge of sending concrete up in a single pressurised pipe to that level is immense and the current Burj Khalifa has set the record for the highest that wet concrete has managed to travel. Another challenge for super tall buildings is the use of fire escapes.
The Kingdom Tower will include a luxury hotel, apartments and condominiums, and the world’s highest observatory inside. The shape of the tower is designed to reduce wind load, which increases with height. The different sized levels will push the wind around the building. It also features tapering wings which are an aerodynamic shape to reduce structural loading due to wind.
At this point it is not entirely certain that the Kingdom Tower will be built, but current testing and investigation will soon prove whether it is possible to create. It is estimated that construction will take 63 months, with the project due for completion in 2018.
