Doka SKE 100s bring Burj core finish closer
Last month, the reinforced concrete construction of the Burj Dubai had reached two thirds of its final height.
Last month, the reinforced concrete construction of the Burj Dubai had reached two thirds of its final height. If work continues to plan, the central structure core, with an overall height of 601m (from the foundations), will be finished by October this year.
The progress of this work has been assured by Doka SKE 100 automatic climbers in the typical storeys of the tower - allowing the central shaft core to be formed in a continuous three-day cycle.
The Doka MF240 climbing-formwork systems used for the outside pillars in the projecting 'nose areas' have also made a major contribution towards speeding up construction operations in the upper storeys, by using the 'climbing ahead' method.
Close attention to workplace safety is ensured by the completely enclosed working platforms of the Doka climbing and automatic climbing formwork, and by the Doka protection-screen system, which is designed to safeguard the exposed slab edges.
Since early 2005, some tough construction and formwork-engineering challenges have had to be solved on the Y-shaped structure core and the wing walls. The honeycombed structural design, with its many airframe-like stiffening reinforcements, dictates an unusually high proportion of wall-forming operations for a high-rise structure. In fact, at 430,000m², the area of wall to be formed on the Burj Dubai is twice as large as that for the floor slabs.
