Capital Gate, the Abu Dhabi office and hotel development set for completion by the end of 2010, has been certified as the World's Furthest Leaning Manmade Tower by Guinness World Records. The project, owned and developed in the UAE capital by 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.
It has earned the Guinness recognition after rigorous evaluation by the Awards committee since January 2010, when the exterior of the 160-metre, 35-storey tower was completed.
Sheikh Sultan Bin Tahnoon Al Nahyan, ADNEC's chairman said: "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."
The project's floor plates are stacked vertically up to the 12th storey after which, they are staggered over each other by between 300mm to 1,400mm giving rise to the tower's dramatic lean.
The lean, of course, puts immense pressure on the core of the building, which uses vertical post-tensioning to resist the stress. The core has been built with vertical pre-cambering and contains more than 15,000m3 of concrete reinforced with 10,000 tons of steel.
Capital Gate’s shell comprises a super-strong exo-skeleton called a ‘diagrid’ that provides a clear, unobstructed floor plate, using far less steel than a conventional structural frame. The external diagrid has more than 720 members with some of the heaviest weighing 16.5 tons.
When completed by the end of this year, Capital will house the five-star Hyatt Capital Gate hotel as well as about 20,000m2 of premium office space.
Capital Gate was designed by international architecture firm RMJM, and the Mace Group is project managing the construction.
