minimize wind effects. As mentioned above, this workers and materials to the required heights. process resulted in a substantial reduction in wind Because of limitations of conventional surveying forces on the tower by confusing the wind — by techniques, a specialized GPS monitoring system encouraging disorganized vortex shedding over the has been developed to monitor the verticality of the height of the tower. The wind tunnel testing program structure. included rigid-model force balance tests, a full aeroelastic model study, measurements of localized pressures, and pedestrian wind environment studies. An extensive program of wind tunnel tests and other The construction sequence for the structure has the central core and slabs being cast first, in three sections; the wing walls and slabs follow behind; and the wing nose columns and slabs follow behind studies resulted in a these. Concrete is substantial reduction in distributed to each wing wind forces on the tower by utilizing concrete booms confusing the wind. that are attached to the Construction methods and technology The Burj Dubai Tower utilizes the latest advancements in construction techniques and material technology. The walls are formed using Doka’s SKE 100 automatic self-climbing formwork system. The circular nose jump form system. Two of the largest concrete pumps in the world were used to deliver concrete to heights over 600 m (1,968 feet) in a single stage. A horizontal pumping trial was conducted prior to the start of the superstructure construction to ensure pumpability of the concrete mixes. columns are formed with circular steel forms, and the floor slabs are poured on MevaDec panel formwork. Wall reinforcement is prefabricated on the ground to allow for fast placement. Three primary selfclimbing Favco tower cranes are located adjacent to the central core, with each continuing to various heights as required. The cranes have been specially modified to be able to lift the extreme lengths of cable required, as well as 25-metric-tonne (27.5-ton) payloads, at high speeds. High-speed (120-m/minute, 393-foot/minute), high-capacity (3,200-kg, 7,050pound) construction hoists were used to transport Conclusion Burj Dubai Tower has eclipsed all previous height records, and is the tallest structure ever built. It represents an enormous collaboration and coordination effort of many individuals across all sectors of the building profession. Conventional and cutting-edge technologies and building systems were utilized, developed, and further advanced to create this unprecedented structure, taking this building and the profession to literally new heights.
