<strong>Burj</strong><br />
<strong>Khalifa</strong><br />
Continued<br />
While the recent development of new structural materials<br />
such as high-strength concrete (the <strong>Burj</strong> <strong>Khalifa</strong>’s<br />
tower core is primarily concrete) and high-speed, supertravel<br />
elevators (the combination low-rise, service/<br />
firefighters’/medical emergency/transformer core replacement<br />
lift, #FE1 has a world record travel of 504.2 meters<br />
[1,654 feet]), certainly have contributed to the viability of<br />
constructing such a tower. The real reasons the iconic<br />
<strong>Burj</strong> <strong>Khalifa</strong> tower was built are more psychological than<br />
economic:<br />
◆ Because we can<br />
◆ Puts Dubai on the international stage<br />
◆ Captures the Guinness Book of <strong>World</strong> Records for the<br />
world’s tallest tower – all three categories<br />
◆ Increases the surrounding building plot values.<br />
As reported in the Wikipedia <strong>Burj</strong> <strong>Khalifa</strong> website listing,<br />
the super tower cost reportedly US$5.5 billion. The iconic<br />
<strong>Burj</strong> <strong>Khalifa</strong> tower is the anchor tower for the surrounding<br />
area, which includes multiple residential towers,<br />
hotels and the latest “world’s largest” mall, the Dubai Mall.<br />
Even though the initial tower costs of the <strong>Burj</strong> <strong>Khalifa</strong><br />
will, no doubt, never be recaptured from the tower resi-<br />

The <strong>Burj</strong> <strong>Khalifa</strong> Tower now holds three world’s tallest<br />
milestone records, as established by the Council on Tall<br />
Buildings and Urban Habitat:<br />
◆ Highest occupied floor: level 162<br />
◆ Highest roof level: 621.3 meters<br />
◆ The distance to any tower top spire or antenna top:<br />
828 meters<br />
All toll, the vertical transportation equipment came<br />
to: US$28,500,000 (awarded to Otis <strong>Elevator</strong> Co.) and<br />
included:<br />
◆ 32 gearless traction lifts<br />
◆ 20 machine-room-less (MRL) lifts<br />
◆ One glass hydraulic (direct plunger, 2 stage jack)<br />
◆ Two wheelchair lifts<br />
◆ One spire rack-and-pinion/workman’s lift<br />
◆ Eight escalators<br />
“Lifeboat” <strong>Elevator</strong> Emergency Evacuations<br />
The <strong>Burj</strong> <strong>Khalifa</strong> is the first building in the world to use<br />
designated express travel elevators for tenant, residents,<br />
employees and visitor evacuations, after a calamitous<br />
event. As the <strong>Burj</strong> <strong>Khalifa</strong> elevator designs were being<br />
planned, shortly after the demise of New York City’s<br />
<strong>World</strong> Trade Center Towers 1 and 2 on September 11,<br />
2001, the architects and consultants were increasingly<br />
concerned that it was virtually impossible to utilize conventional<br />
emergency exit stairs alone to evacuate the<br />
building occupants. Thus, was born the idea to specify
