The tower which will soon become the highest building in the world is currently being built in Saudi Arabia. Jeddah Tower (previously called Kingdom Tower) is expected to break the one-kilometer mark, making it 180 meters higher than the Burj Khalifa Tower in Dubai. The tower structure has been engineered by consulting firm Thornton Tomasetti and is built by contractor Saudi Bin Laden.

Jeddah Tower will ultimately host a 200-rooms Four Seasons hotel, service apartments, several floors of offices and an observatory. A total of 59 elevators will allow visitors to move between floors.

To support this engineering prowess, Dextra is proudly delivering Bartec Couplers for both foundations and superstructure packages of the Jeddah Tower. Two main types of Bartec couplers are used: Standard and Bridging Assemblies.
