The structure is made up of roughly 70,000 m3 (92,000 cu yd) of concrete and 9,000 tons of steel. The atrium inside the structure is 180 meters (590 feet) tall. The north-facing facade of the 18-story atrium is surrounded by 12 independently tensioned two-layer membrane panels. These are the only exterior walls that do not contain windows.
When completed in 1990, the Burj al Arab was the tallest free-standing structure in the world. It has since been surpassed by several other buildings, but it remains the largest floating hotel structure ever built. The tower is located in Dubai, United Arab Emirates. It stands 1,722 feet (541 meters) high.
The name "Burj" means "tower" in Arabic. It is also the title of the book that describes the creation of the original tower: "The Book of Genesis".
The building is owned by the Sultan of Brunei who also owns the neighboring island on which the tower is moored. He had it built as a gift for his wife, who later became known as "Sheikha Latifa".
It took seven years to complete the tower at a cost of $40 million. The main contractor was ARKA Engineering & Construction Ltd., with UGL Group serving as an associate contractor. The foundation consists of 150,000 cubic meters of rock excavated from beneath the surface of the island on which it stands.
Overview The structure is intended to be at least 1,000 meters (3,281 feet) tall (the exact height is being kept private while in development, similar to the Burj Khalifa). It is expected to become the tallest building in the world.
Construction on the Jeddah Tower began in 2014 and is expected to be completed in 2020. The tower will contain more than 50 floors above ground with a spire topping out at 441 meters (1452 feet). There are plans to add another floor or two once the building has reached its full height, bringing the total number of floors to around 60.
The tower is being built by Saudi Arabian developer Al Rajhi Group and is expected to offer some of the best views in Jeddah. Its appearance is meant to reflect the heritage of the city's port district, which used to be home to several medieval towers.
In addition to being the highest skyscraper in the kingdom, the Jeddah Tower will also be the most expensive when it is complete. It costs about $350 million to build this tower - thus making it valuable not only as a viewing platform but as an investment too.
Flatiron Structure/Height: 98 feet (29 m)
The Flatiron Building is a 48-story landmark skyscraper in New York City. It is located at 23-25 West 22nd Street between Fifth and Sixth avenues. Built by William K. Flatiron, it was completed in 1924.
The building has been called "the most famous work of art outside the Metropolitan Museum" and is designated a National Historic Landmark. It is currently occupied by Condé Nast. The Flatiron Building is also known as the "Condom" due to its shape; however, this name originates from a T-shirt brand that formerly had its headquarters there.
The nickname "condom" dates back to at least 1928 when The New Yorker magazine described it as a "newly erected twenty-five story 'condom'". By 1949, the word had made its way into common usage. By 1960, the term was being used by other publications too, such as Sports Illustrated which referred to it as a "newly erected twenty-five story 'condom'" that year.
