CHINA'S tallest skyscraper may be in trouble even before it is built.
The foundations for the 108-story, 510-meter China Zun were laid in Beijing's CBD yesterday but questions have been raised over whether it will meet firefighting standards.
According to previous media reports, the skyscraper will have high-speed elevators in the upper part of the building to shorten the time taken to escape in the event of an emergency.
But this could pose a huge danger in the event of a fire, Ma Jianmin, head of the Construction Projects Approval Office at the Beijing Public Fire Department, said.
"Elevators can never be used when fire breaks out in a high-rise," Ma said, according to yesterday's Beijing Evening News.
"A power failure will trap people in the elevator and smoke will concentrate in the elevator shaft."
Ma also said the top floor of the building should have a landing area for helicopters but, according to the plans, the top floor is to be an observatory giving visitors a bird's-eye view of the capital.
Aerial ladders, which are normally 90 meters or 101 meters high, would have limited use in case of a high-rise inferno.
Ma said that for buildings more than 100 meters high, some floors needed to be set aside and properly equipped for people to take refuge.
Skyscrapers should also be equipped with fire extinguishing facilities including smoke emission channels and evacuation passageway that comply with national standards, Ma told the newspaper.
The building, shaped like a zun, an ancient Chinese wine vessel, will be the headquarters of the state-owned CITIC Group.
It will become the highest building in China's capital after its completion in five years, surpassing the 330-meter China World Trade Center Tower 3, and the tallest building in China itself.
Currently, the tallest building in China is Tapei 101 in Taiwan at 508 meters.
Shanghai's World Financial Center is the country's second highest at 492 meters.
