While Downtown Dubai is graced with the 828m-high Burj Khalifa, the world’s tallest building, the other end of the city, Dubai Marina, is host to another vertical record: the tallest block in the world. Here a bunch of super-tall towers are clustered together in a single block, ranging from 250m to over 500m.
The block contains the Princess Tower, the Pentominium, Elite Residences, Marina 101, 23 Marina, the Marina Torch and Damac Heights.
Developer of the 414m-high Princess Tower, Tameer Holding Investment, announced that main contractor Arabian Construction Company (ACC) has completed the super-structure with handover scheduled for 2012.
Princess Tower comprises 100 floors offering 763 apartments. The total built-up area of the project is 162,580m2 and eight retail spaces are located on the ground floor.
Finnish elevator specialist KONE has supplied a number of the towers in the vertiginous block, including Princess Tower, Elite Residence, The Torch and Infinity Tower.
At Princess Tower, KONE’s JL100 JL100 JumpLift was used in two phases. A JL100 was used for heights of up to 300m, with a single JL2000 traversing the building’s entire height.
The tower has a bank of 13 elevators and the size and complexity of the project meant that KONE was involved from the inception. It is one of the most complex projects that the company has worked on.
Meanwhile, the nearby Elite Tower parades the largest JumpLift operation in the world. Here a JL2000 operates at a load of 4,000kgm, a speed of 4m/s and a travel of 400m.
Rod Burns, ACC project manager at Elite Residence, comments: “We are on a quite restricted area of the Dubai coast, where we have had some very of strong winds, restricting the use of external hoists and thus impacting productivity.”
In a few months, Dubai will contain the four tallest residential towers in the world. The current list by the Council for Tall Buildings and Urban Habit puts Dubai’s The Torch (348m) in top position. The 323m Q1 Tower in Australia comes second, while the 318m HHHR in Dubai takes third.
This will change by January 2012 when Princess Tower will take the top position, followed by the 395m-high 23 Marina and the 381m-high Elite Residence. The Torch will thereafter be ranked fourth.
However, by end of 2013, The Pentominium from Trident International Holdings will be number one at 516m.
