The Burj Khalifa is founded on pile supported raft foundation consisting of 194 bored-in-situ piles or drilled shafts as we commonly call them in the US with a 12 foot thick mat. The piles were 1.5 meters (5 feet) in diameter and extended 140 feet below the mat. The piles had an allowable axial load of 3,000 tonnes (6,614 kips) and load tests were performed on piles up to 6,000 tonnes.
