An estimated 80kt of steel will be used in the construction of what will be the world’s tallest building.

To be known as the Kingdom Tower, it will tower over 1,000 metres in height, occupy a construction area of 530,000 square metres and cost US$1.2 billion. The building will be the centrepiece and first construction phase of the US$20 billion Kingdom City development near the Red Sea.

The planned 160-floor building, which will be completed in five years, will offer a mix of residential, office space and commercial units and will feature the world’s highest observation deck on the 157th floor.

According to Adrian Smith & Gordon Gill Architecture, The Kingdom Tower’s design is both highly technological and organic ‘with tapered wings producing an aerodynamic shape that helps to reduce structural loading due to wind vortex shedding’. The building’s exterior wall will feature a high performance system designed to minimise energy consumption by reducing thermal load. “The new construction will take advantage of new and innovative thinking about technology, building materials, life-cycle considerations and energy conservation,” said the company.

The Kingdom Tower will contain 59 elevators (lifts), five of which will be double-decker configurations, as well as 12 escalators.
