Dubai Opens World's Tallest Building

The financially troubled Gulf emirate of Dubai has opened the world's tallest building, a concrete, glass and steel goliath rising 828 metres out of the desert sands.
 
Spectacular fireworks flowed up and down the massive structure after it was officially opened by Dubai ruler Sheikh Mohammad bin Rashed al-Maktoum on Monday.
 
He renamed the building, previously known as Burj Dubai, Burj Khalifa in honour of United Arab Emirates President Sheikh Khalifa bin Zayed al-Nahayan.
 
Sheikh Khalifa is also ruler of Abu Dhabi, the emirate which came to Dubai's help late last year to the tune of $US10 billion ($A11.15 billion) to bail out troubled property developer Nakheel, a subsidiary of Dubai World.
 
"Today the United Arab Emirates achieves the tallest building ever created by the hand of man... and this great project deserves to carry the name of a great man. Today I inaugurate Burj Khalifa," Sheikh Mohammad said.
 
Parachutists bearing the UAE colours of red, green, black and white then touched down as a giant portrait of Sheikh Khalifa was projected on an outer wall of the structure which cost $US1.5 billion ($A1.67 billion) to erect.
 
Dubai hopes the opening of the Burj Khalifa - the latest in a series of grandiose projects - will burnish an image tarnished by its crippling debt woes.
 
The needle-shaped tower, described by its developer as a "vertical city" as it dwarfs existing skyscrapers, boasts new limits in design and construction.
 
Emaar Properties, the partly government-owned developer, had maintained the suspense about the skyscraper's final height, saying only that it exceeded 800 metres.
 
On Monday it said the tower had more than 200 floors, only 160 of which would be inhabited, while the remaining floors were for services.
 
Burj Khalifa has a total built-up area of 530,000 square metres, including 170,000 square metres of residential space and more than 28,000 square metres of prime office space, Emaar said.
 
This amounts to 1,044 apartments and 49 floors of office space, served by 57 lifts. It also has a hotel carrying the Georgio Armani logo.
 
Bill Baker, a structural and civil engineer and partner in Chicago-based Skidmore, Owings and Merrill (SOM), which designed the tower, said it has set a new benchmark.
 
"We thought that it would be slightly taller than the existing tallest tower of Taipei 101. (Emaar) kept on asking us to go higher but we didn't know how high we could go," he said.
 
"We were able to tune the building like we tune a music instrument. As we went higher and higher and higher, we discovered that by doing that process... we were able to reach heights much higher than we ever thought we could."
 
A spiralling Y-shaped design by SOM architect Adrian Smith was used to support the structural core of the tower, which narrows as it ascends. Higher up it becomes a steel structure topped with a huge concrete spire.
 
To reach the final stages, concrete was lifted to a height of 605 metres - a world record.
 
The opening of the tower comes, however, after the once-booming real estate sector of the emirate has crashed, halving the value of most Dubai properties in comparison with peak prices recorded in the summer of 2008.
 
It also comes as Dubai battles a serious debt crisis, resulting from the heavy borrowing by some of its state corporates to finance massive property projects.
 
The emirate narrowly escaped financial catastrophe last month as neighbouring Abu Dhabi threw it a last-minute lifeline worth $US10 billion to pay imminent debt owed by Dubai World.
 
The group last month began negotiations with its creditors with the hope of reaching an agreement over restructuring an accumulated debt of $US22 billion ($A24.5 billion) amassed by its troubled subsidiaries.
 
Dubai's total debt, mostly that of its state-owned companies, amounts to $US100 billion ($A111.5 billion).
 
Abu Dhabi, and the Abu Dhabi-based central bank of the United Arab Emirates, have extended financial aid of $US25 billion ($A27.9 billion) to Dubai since it announced early last year it needed to sort the debt problem of its firms.
 
Dubai's economy was hard hit by the global financial crisis, which turned off the tap on vital foreign finance badly needed for its growth plans.
