Capital Gate (translated from English means “Gate of the Capital”) is a unique skyscraper in the capital of the United Arab Emirates – Abu Dhabi. With a height of 160 meters, this building has become one of the tallest in the city. The skyscraper is also known as the Abu Dhabi Leaning Tower. Capital Gate entered the Guinness Book of Records as the building with the largest slope in the world.

The slope of the building to the west is 18 degrees. For comparison: the angle of inclination of the famous Leaning Tower of Pisa is only 4 degrees, that is, 4,5 times less (read interesting facts about the Leaning Tower of Pisa here ☛). In June 2010, the Guinness Book of Records recognized Capital Gate as the building with the largest angle of inclination in the world.

A similar angle of inclination in the project was realized thanks to a peculiar engineering approach: the plates of the tower floors were superimposed on one another strictly vertically up to the 12th floor, above which they were located with gaps from 30 to 140 centimeters, providing a slope.

Capital Gate is said to be the first structure in the Middle East to use diagonal mesh technology designed to absorb and redirect wind and seismic pressure. Among skyscrapers similar to it are the Mary Ax in London, as well as the Hearst Tower in New York.

Architectural features of Capital Gate

A dense mesh of reinforcing steel is placed on top of 490 piles, which are driven 30 meters underground. 728 specially made diamond-shaped glass panels are attached to the grid, which, due to the complex geometry of the structure, are installed at special angles. In total, the tower contains more than 12500 glasses, which significantly reduces the cost of artificial lighting of the premises. Also in the building is a conical atrium 60 meters high.

An atrium is a large open space inside a building.

The latest environmental developments were used in the construction of the skyscraper. The windows of the building block the sun's rays, thereby reducing the consumption of electricity for air conditioning. The undulating decor on the outside of the tower also acts as a heat shield. The steel canopy on the south side reduces the solar heat flux by more than 30%.

The skyscraper has 35 floors and has more than 16000 square meters of usable office space. The building houses the five-star Hyatt at Capital Gate Hotel, and the Andaz Hotel on floors 18 to 33, office and service space.

Capital Gate is owned and developed by the Abu Dhabi National Exhibition Company and is owned by RMJM London. Construction of the Abu Dhabi Leaning Tower began in September 2007 and was completed in December 2011. The construction estimate was $2,2 billion.
