The building leans westward at 18 degrees, more than five times the angle of the Leaning Tower of Pisa. The top 17 floors, out of a total of 35, hang over the edge, putting thousands of tonnes of pressure on the core of the building.
Contractors and engineers devised a series of solutions to this problem, some of which have never been seen in the world of tower construction. In fact, this unique challenge is the reason that National Geographic is featuring the building along with Sheikh Zayed Mosque and the circular Aldar headquarters building as the “making of three modern day wonders” starting on Saturday.
To understand the epic engineering challenges of building the leaning Capital Gate tower in Abu Dhabi, you must first realise that nature wants it to collapse.
“Everything about the tower makes it want to fall over,” says Michael Johnson, who has been appointed to oversee the final phase of construction of the building by the Abu Dhabi National Exhibitions Company (ADNEC). “But it has been designed to stop.”
