The Corporate Suites occupy most of the remaining floors, except for level 122 which houses At.mosphere and level 124, the tower's public observatory, At the Top, Burj Khalifa.įor the convenience of homeowners, the tower has been divided into sections with exclusive Sky Lobbies on Levels 43, 76 and 123 that feature state-of-the-art fitness facilities including a Jacuzzis on Level 43 and 76. Levels 9 to 16 will exclusively house luxurious one and two-bedroom Armani Residences.įloors 45 through 108 are private ultra-luxury residences. Floor PlanĬoncourse level to level 8 and level 38 and 39 will feature the Armani Hotel Dubai. Special studies were carried on Burj Khalifa to determine the magnitude of the changes that would have to be dealt with in the building design. Stack effect or chimney effect is a phenomenon that affects super-tall building design and arises from the changes in pressure and temperature with height. Even the temporary conditions during the construction stage were tested with the tower cranes on the tower to ensure safety at all times. These ranged from initial tests to verify the wind climate of Dubai, to large structural analysis models and facade pressure tests, to micro-climate analysis of the effects at terraces and around the tower base. Over 40 wind tunnel tests were conducted on Burj Khalifa to examine the effects the wind would have on the tower and its occupants. Viewed from the base or the air, Burj Khalifa is evocative of the onion domes prevalent in Islamic architecture. A Y-shaped floor plan maximizes views of the Arabian Gulf. The central core emerges at the top and culminates in a sculpted spire. Twenty-six helical levels decrease the cross-section of the tower incrementally as it spirals skyward. The modular, Y-shaped structure, with setbacks along each of its three wings, provides an inherently stable configuration for the structure and provides good floor plates for residential. The tower is composed of three elements arranged around a central core. The architecture features a triple-lobed footprint, an abstraction of the Hymenocallis flower. The selected design was subject to an extensive peer review program to confirm the safety and effectiveness of the structural systems. Ultimately, the honour of designing the world's tallest tower was awarded to the global leader in creating ultra-tall structures, the Chicago office of Skidmore, Owings & Merrill LLP (SOM) with Adrian Smith FAIA, RIBA, consulting design partner. The centrepiece of this new world capital attracted the world's most esteemed designers to an invited design competition. While it is superlative in every respect, it is the unique design of Burj Khalifa that truly sets it apart.
