RESOURCES The primary structure is reinforced concrete .

Super high pressure trailer concrete pump .

Used 330,000m cube,55000 tones of steel rebar.

22 million man-hours .

3 tower cranes were used during the construction of upper most

levels ,each capable of lifting 25 tonne load.

The remaining structure is constructed of lighter steel .

A high density , low permeability concrete was used in the foundation

A cathodic protection system is used to minimize any detrimental effects

from corrosive chemicals in local ground water.

It is highly compartmentalised with air –conditioned floors

Construction method and technology The Burj Dubai Tower utilizes the latest advancements in construction techniques and material technology. The walls are formed using Doka’s SKE 100 automatic

self climbing formwork system. The cranes have been specially modified to be able to

lift the extreme lengths of cable required. High speed ,high capacity construction hoists were

used to transport the workers and materials to the working place.

An extensive program of wind tunnel tests and other studies were under taken by the wind tunnel consultant.

A specialized GPS monitoring system has been developed to monitor the verticality of the structure.
