The Tallest Building in the World – The Burj Khalifa, Dubai (UEA)

Burj al Khalifa is a symbol of modernity and architectural excellence in the UAE.

The Burj Khalifa (Arabic: برج خليفة‎ Burǧ Ḫalīfah “Khalifa Tower”), formerly known as The Burj Dubai برج دبي, is a supertall skyscraper in Dubai, United Arab Emirates, and is the tallest man-made structure ever built, at 828 m (2,717 ft).

Construction began on 21 September 2004, with the exterior of the structure completed on 1 October 2009 and the building officially opened on 4 January 2010, when Burj Dubai was renamed to Burj Khalifa officially in honor of the current President of the UAE and ruler of Abu Dhabi, Sheikh Khalifa bin Zayed al Nahyan. Inofficially the renaming was one of the conditions for the $60 billon debt bailout of bankrupt Dubai by Abu Dhabi.

The building is part of a huge development located at the First Interchange (aka “Defense round-about”) along Sheikh Zayed Road at Doha Street. Skidmore, Owings and Merrill LLP (SOM) of Chicago is the lead architect, structural engineer and mechanical engineer of the Burj Khalifa. George Efstathiou of SOM is the Managing Partner on the project, while Adrian Smith, formerly of SOM, was the Design Partner. Third Party Peer Review has been performed by CBM Engineers Inc.
