Construction of the world's tallest skyscraper in Jeddah is going ahead and I the $1.5 billion project is being built by the Jeddah Economic Company.
The firm's chief executive Mounib Hammoud said he hopes the tower will be opened by 2020.
The Jeddah Tower features residential and hotel space as well as shopping facilities.
It is projected to be over 1,000 metres (3,281 feet) tall, eclipsing Dubai's Burj Khalifa, which is currently the world's tallest building at over 828 metres.
Construction has reached the 63rd floor. The superstructure including the concrete shell and the cladding will be completed next year.
The concrete mix has to be approved by a structural engineering firm in Chicago every month, given the potential impact on it of Jeddah's changing temperatures and winds. Experts must check almost every week that the tower is 100 percent vertical.
