World's tallest building to be built in only 90 days

Chinese construction company Broad Group has announced ambitious plans to construct the world's tallest skyscraper in an implausibly swift 90 days. If the target is met, the 838-meter (2,750-ft) "Sky City One" will take only a twentieth of the time that the Burj Khalifa, the world's current tallest building, took to construct, and will stand 10 meters (33 feet) taller still upon completion. The secret to the rapid construction is prefabrication. Approximately 95 percent of the building will have been put together in modular form before work even commences on site.

According to CNN the Sky City One will contain 1,000,000 sq m (10,800,000 sq ft) of usable floor space and its 220 floors will be connected by 104 separate elevators. Broad CEO Zhang Yue reportedly claims that the tower will consume only one fifth of the energy of a conventional building of its size (if you can call any building this tall conventional) due to sustainable design approaches built into the BSB concept including 15-cm (6-inch) thick exterior walls and quadruple glazing, both of which up Sky City's insulation.

CNN reports that the the Sky City One is projected to cost US$628 million: positively cheap when compared to the $1.5 billion Burj Khalifa. Work is due to commence on site in November 2012 with completion due the following January, though final approval from Chinese authorities is yet to be granted.

Details
838 meters tall | 220 floors | 1,000,000 square meters | 200,000 tonnes of steel | 104 elevators
83% of space will be residential, with maximum capacity at 174,000 residents
5% hotel, 1,000 patrons
3% school, 4,600 students
3% hospital, 1,400 patients
3% office, 2,000 workers
3% retail, 5,000 shoppers
Total max capacity at 31,140 persons

Status
Location: Wangcheng district, next to Xiangjiang River
Assembly starts Nov 2012
Construction ends Jan 2013
Contractor: BSB and other associates

Method
Designed by Burj Khalifa's architect. Materials sourced from BSB. 95% of the man-work hours are actually done at the BSB plant. 5 floors will be assembled everyday.

Safety
Able to resist magnitude 9 earthquakes (while the current standards in Changsha is 6). The progressive pyramidal shape allows it to resist 9 scale quakes. The materials used are fire resistant for at least 3 hours. 10 emergency evacuation channels will allow the building to be completely evacuated in 15 minutes

Environmental standards
15cm thick insulation, 4 layered glass windows, BSB's air conditioning more than 5 times energy efficient than conventional units
LED lighting, elevator braking power generators, 6 times less reliance on the power grid than conventional buildings
Extremely efficient on land usage with a vertical transportation system rather than horizontal
BSB's air freshening system completes 7 air filtration cycles every hour. Indoor air will be 20 times cleaner than outdoors.

Project starts April this year, has not received government approval. Because details of this building were leaked on 5 June at the associate appointment conference, we were forced to reveal the full plan at the same time. The announcement was supposed to be in August

Aim:
1. Practically demonstrate the government's targets of sustainability and resource efficiency in construction
2. Testing the future direction of urbanism in China
3. Increase the people's standard of living
4. Increase BSB's technological capabilities
We are not just building another landmark, but is revolutionizing a new approach to urban living, by using minimal cost and resource to achieve maximum utility

Most of Sky City’s 220 floors will be apartments for 174,000 people, and the rest will house a hotel, school, hospital, offices, shops, and restaurants.

Broad believes it doesn’t need much money to complete the project. The company says Sky City will cost four billion yuan, about $628 million. Dubai’s Burj, on the other hand, required an estimated $1.5 billion to build.

Impossible to do at that cost; even in that "neighborhood"

Also reminds me a bit of arco's out of SimCity

Looks a bit like the Empire State Building. It is going to be assembled in 90 days. How long to make all the prefabricated sections?

Looks interesting. But I dunno about the massive space on the inside with little to no natural light..
It does seem like Titanic, though. 15 min for full evacuation of this massive building? Schools, agriculture, hotel and housing? Earthquake resistant, fire resistant.. and built in such a short time? Sounds like a hoax :/

They must be compensating for a tiny plot of land.

sjwaldron · 06-21-2012, 01:21 PM

Certainly sounds impressive, both in time to completion and estimated cost. They must be well into constructing the prefabricated sections if they are going to start in November.

You missed the point. If they can't get a 12 story building to stay up, why would you trust them with a 30+ story one.

Besides, China is building ghost cities that are new but already starting to decay. Do some research and you will see.

China expanding so quickly due to all of the finance money from america; not that China would ever need financing - but america needs money from China. As a matter of fact the american debt to China is not capable of being repaid - does nothing but get worse as time goes on.

So please help China in building more skyscrapers by shopping at ones local Walmart.
