Saudi Bauer Foundation Contractors, a unit of Bauer Spezialtiefbau, has secured a €25m contract to provide foundation works for the $1.2bn Kingdom Tower in Jeddah, Saudi Arabia.
As per the deal, Bauer will construct 270 bored piles of 1.5 and 1.8m diameters to depths of about 110m.
Bauer will use two BG28 and two BG40 piling rigs to complete the work, which is expected to start on site in December 2012 and take around ten months.
Designed by US-based Adrian Smith + Gordon Gill Architecture, Kingdom Tower will be over 1km in height and spread across an area of 530,000m².
The 161-storey tower forms part of the first construction phase of Kingdom City, a 5.3 million m² mixed-use development north of Jeddah.
The building will feature a hotel, apartments, offices, three lobbies on the upper floors and an observation deck on the 157th floor.
Kingdom Tower will also accommodate a high-end shopping mall, additional development parcels that will house commercial and high-density residential buildings and open spaces, including the central tower plaza.
The tower will contain 59 elevators, including 54 single-deck and five double-deck elevators, along with 12 escalators.
The structure will feature a high-performance exterior wall system that will minimise energy consumption by reducing thermal loads, while three sides of the building will feature a series of notches that create pockets of shadow, shielding parts of the building from the sun.
Upon its completion in 2018, the tower is expected to be the tallest in the world, 173m taller than the current tallest building, the 828m Burj Khalifa in Dubai.
The entire Kingdom City Jeddah project is expected to cost SR75bn ($20bn) and take ten years to complete.
