ADNEC leaning towards new world record

An Abu Dhabi developer is leaning towards a new world record – the most inclined tower in the world.

Abu Dhabi National Exhibitions Company (ADNEC) and project architects RMJM have submitted a joint application to the Guinness Book of Records for the Capital Gate tower project.

The tower, which leans 18 degrees to the west, will lean four times as far as Italy’s famed Leaning Tower of Pisa, which leans less than four degrees.

“Capital Gate will be one of a kind,” RMJM Asia and the Middle East CEO David Pringle said.

“Its asymmetric diagonal structure, known as a diagrid, supports the tilting external load of the building and we believe that this is the first building in the world to use a pre-cambered core.”

Capital Gate is being constructed on a dense mesh of reinforced steel to support its posture.

The mesh itself sits above 490 piles which have been drilled 30m into the ground to allow for the gravitational, wind and seismic pressures caused by the lean of the building.

The Guinness Book of Records currently does not list the world’s most inclined building, meaning a new category will have to be created if Capital Gate is to enter the record books.

The tower, which is due to open next year, will stand 160m spread over 35 stories.

It will also include 728 custom made diamond shaped glazing panels. Each pane of glass is a different shape and must be fitted at a slightly different angle due to the curving shape of the structure.

The tower forms part of the US $2.2 billion (AED8 billion) Capital Centre Development, a business and residential “micro city” being constructed around the Abu Dhabi National Exhibition Centre.

The tower will accommodate the Hyatt at Capital Centre hotel, and will provide the city with additional office space.
