Capital Gate in Abu Dhabi, has been certified as the ‘World’s Furthest Leaning Manmade Tower,’ by Guinness World Records.
Currently under construction by HLG, Capital Gate, owned and developed by the Abu Dhabi National Exhibitions Company (ADNEC), has been built to lean 18 degrees westwards - more than four times that of the world famous Leaning Tower of Pisa. Capital Gate earned the Guinness recognition after rigorous evaluation by the Awards Committee, following exterior completion of the 160-metre, 35-storey tower earlier this year.
Capital Gate’s floor plates are stacked vertically to the 12th storey, after which they are staggered over each other by between 300 millimetres to 1,400 millimetres, 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.
Senior Construction Manager for HLG, Leslie Fairchild said:
“The Capital Gate structure has been a most challenging and enjoyable engineering project.
“Every day has brought new challenges for the team, requiring us to come up with some exceptional solutions.
“We have a very strong site team and excellent sub-contractors who worked closely together to ensure the project’s success.”
When fully complete by the end of this year, Capital Gate will house the 5-star Hyatt Capital Gate hotel as well as approximately 20,000 square metres of premium office space.
