Lego burj khalifa - 21008 Instruction Manual
Over 45,000 m3 (58,900 cu yd) of concrete, weighing more
than 110,000 tonnes were used to construct the concrete
and steel foundation, which features 192 piles buried
more than 50 m (164 ft) deep. Burj Khalifa’s construction
will have used 330,000 m3 (431,600 cu yd) of concrete
and 39,000 tonnes (43,000 ST; 38,000 LT) of steel rebar,
and construction will have taken 22 million man-hours.

In November, 2007, the highly reinforced concrete
corewalls were pumped using 80 MPa concrete from
ground level; a vertical height of 601 metres. Smashing
the previous pumping record on a building of 470m
on the Taipei 101; the world’s second tallest tower and
the previous world record for vertical pumping of 532
metres for an extension to the Riva del Garda Hydroelectric
Power Plant in 1994. The concrete pressure during pumping
to this level was nearly 200 bars.

The tower accomplished a world record for the highest
installation of an aluminium and glass façade, at a height
of 512 metres. The total weight of aluminium used on Burj
Dubai is equivalent to that of five A380 aircraft and the
total length of stainless steel bull nose fins is 293 times
the height of Eiffel Tower in Paris.

The amount of rebar used for the tower is 31,400 metric
tons – laid end to end this would extend over a quarter of
the way around the world.

Exterior cladding of Burj Khalifa began in May 2007 and
was completed in September 2009. The vast project
involved more than 380 skilled engineers and on-site
technicians. At the initial stage of installation, the team
progressed at the rate of about 20 to 30 panels per day
and eventually achieved as many as 175 panels per day.
