during constructionit is the tallest MAN made structure in the world.
Construction began on 6 January 2004 & the exterior of the structure completed on 1 October 2009.
Foundation
The superstructure is supported by a large reinforced concrete mat, which is in turn supported by bored reinforced concrete piles. The design was based on extensive geotechnical and seismic studies
A high density, low permeability concrete was used in the foundation
cathodic protection system under the mat to minise the corrosive action due to presence of groundwater
Podium
its provides base anchoring to the tower to ground, it is constructed with a suspended cable-net structure .
Exterior Cladding
exterior cladding comprised of reflective glazing with the aluminium & stainless steel.
it has ore than 25k glass panels used in exterior cladding of the building.cladding system is used to withstand the dubai's hot summer.for cladding work the cladding specialist are hire from china.
Structural System
burj khalifa is made such a way that it has asthetic & functional advantage.
the spiraling “Y” shaped plan was utilized to shape the structural core of Burj Khalifa. this design will be helpful in reducing the wind forces on the strcuture.
Mechanical, Electrical & Plumbing
To achieve the greatest efficiencies, the mechanical, electrical and plumbing services for Burj Khalifa were developed in coordination during the design phase with cooperation of the architect, structural engineer and other consultant.
The tower's water system supplies an average of 946,000 litres (250,000 gallons) of water daily
At peak cooling, Burj Khalifa will require about 10,000 tons of cooling, equal to the cooling capacity provided by about 10,000 tons of melting ice
Dubai's hot, humid climate combined with the building's cooling requirements creates a significant amount of condensation. This water is collected and drained in a separate piping system to a holding tank in the basement car park
The condensate collection system provides about 15 million gallons of supplement water per year, equal to about 20 Olympic-sized swimming pools
The tower's peak electrical demand is 36mW, equal to about 360,000 100 Watt bulbs operating simultaneously
Fire Safety
for fire safety purpose the building design is just said to be an awesome.
the lift capacity is 5500kg is installed for easily evacuation of structure.
since the 160floorsis too much high so at each 25 floor there is pressurized, air conditioned room.
Elevators & Lifts
burj khalifa has 57 elevator & 8 escalators
Burj Khalifa will be the first mega-high rise in which certain elevators will be programmed to permit controlled evacuation for certain fire or security events. Burj Khalifa's Observatory elevators are double deck cabs with a capacity for 12-14 people per cab. Traveling at 10 metres per second, they will have the world's longest travel distance from lowest to highest stop.
The world's most-prestigious address will be home to a select few. With 900 residences including studios, one-, two-, three- and four-bedroom suites, The Residences at Burj Khalifa are designed for the connoisseur. High living becomes a reality where the homes are located on levels 19 to 108 of Burj Khalifa.
has 11 hectare of greenery with two tennis courts.
