- Project Description

Arabtec has worked on several prestigious projects, including, of course, Burj Khalifa - the world’s tallest building.

History was made in January 2010 when Arabtec, in association with Samsung Corporation of Korea and Besix of Belgium, completed the 828 metres high Burj Khalifa, the tallest building in the world.

Burj Khalifa is the tallest structure in the world in all four of the criteria listed by the Council on Tall Buildings and Urban Habitat (CTBUH):

  • To Structural Top: Height to structural top of the building.
  • To Highest Occupied Floor: Height to the floor of the highest occupied floor of the tower.
  • To Top of Roof: Height to the top of the roof.
  • To Tip of Spire/Antenna: Height to the tip of spire, pinnacle, antenna, mast, or flag pole.

Burj Khalifa is the centrepiece of Emaar’s Downtown Area, a $20 billion, 500-acre downtown development billed as the most prestigious square kilometre on earth.

The tower has been designed to manage the effects of wind and seismic movements and high-strength concrete makes up the tower’s super-structure, which is supported by large reinforced concrete raft foundation and piles. The 80,000 square feet foundation slab and 50-metre deep piling are waterproofed and feature cathodic protection.

The steel bars that reinforce the structure weigh a total of 31,400 tonnes, which if laid end to end would stretch more than a quarter of the way round the world! The concrete used is equivalent to a solid cube of concrete 61 metres in size, or a 1.5-metre wide pavement, 1,200 miles long. It weighs the same as 100,000 elephants!

Primary materials of the exterior cladding system are reflective glazing, aluminium, textured stainless steel spandrel panels and vertical stainless steel tubular fins which accentuate the height and slender design of the tower.

Many of the floors are occupied by the Armani Hotel. In addition, there are luxury residential suites designed by Giorgio Armani which were fitted out with Armani home furnishing products. Floors 19 to 108 contain 800 private apartments, whilst the higher floors are being used as offices and private suites. 442 metres above the ground on the 124th floor there is an observatory accessible to the general public.

Burj Khalifa does stagger the imagination. At peak cooling time, for example, the tower requires 10,000 tones of cooling per hour, which is equivalent to the capacity provided by 10,000 tones of melting ice in one day. Meanwhile the tower’s water system will supply an average of about 946,000 litres of water per day.

The tower’s peak electricity demand is roughly equivalent to 360,000 100-watt bulbs all operating at the same time, while its condensate collection system is truly the finest the 21st century can provide.

It’s highly environmentally friendly too, with all of the condensed water being collected and drained in a separate piping system down to a holding tank located in the basement car park. The water is then pumped into the site’s irrigation system for use on the tower’s landscape plantings. This system provides around 15 million gallons of supplemental water a year, equivalent to nearly 20 Olympic-sized swimming pools.

The tip of the spire is visible 60 miles away.
