CAPITAL GATE, owned and developed in Abu Dhabi, the capital of the United Arab Emirates, by ADNEC (Abu Dhabi National Exhibitions Company), has been certified as the ‘World’s Furthest Leaning Manmade Tower,’ by Guinness World Records.
CAPITAL GATE has been built to lean 18 degrees westwards – more than four times that of the world famous Leaning Tower of Pisa – and, earned the Guinness recognition after rigorous evaluation by the Awards Committee since January 2010, when the exterior of the 160-metre (524.9 ft), 35-storey tower was completed.
“CAPITAL GATE is a landmark development for Abu Dhabi and with this recognition the tower takes its place among the world’s great buildings. It is a signature building which speaks to the fore-sight of the emirate”.
CAPITAL GATE’s floor plates are stacked vertically up to the 12th storey after which, they are staggered over each other by between 300mm to 1400mm giving rise to the tower’s dramatic lean.
The tower features other innovative construction techniques including the world’s first known use of a ‘pre-cambered’ core, which contains more than 15,000 cubic metres of concrete reinforced with 10,000 tons of steel. The core, deliberately built slightly off centre, has straightened as the building has risen, compressing the concrete and giving it strength, and moving into (vertical) position as the weight of the floors has been added.
