Burj Khalifa’s foundation is made up of 125 piles that are 1.5 metres in diameter and 50 meters inlength, comprising 45,000 cubic metres of concrete, reinforced with steel.The foundation was designed to support the total building weight of approximately 450,000 tonnes. Watch the video from Lesics:
This weight was then divided by the compressive strength of concrete which is 30 MPa which yielded 450 sq. meters of vertical normal effective area, which then yielded 12 meters by 12 meters dimensions.

A cathodic protection system is under the concrete to neutralize the sulphate and chloride-rich groundwater and prevent corrosion.The remaining structure above was constructed of lighter steel.
