Video: China completes 30-story building in 15 days

China is nowadays known to the world as a huge construction site where superlative and larger-than-life skyscrapers spring up faster than anywhere else. At the end of 2010, a video in fast motion documenting the completion of a 15-story building within merely 6 days left most viewers’ jaws drop. This time, the same company broke its own record, by erecting a 30-story building from scratch in 15 days, or 360 hours.

The Ark Hotel was built on Dongting lake, in south China’s Hunan Province, by Broad Group, a Chinese construction company which specializes in sustainable architecture. The project was capped with no injury to any worker. It was allegedly built to withstand a magnitude 9 earthquake, as tested by the China Academy of Building Research, or five times more quake-resistant than conventional buildings.

All the materials were prefabricated and sections built to specification off-site, so there was very little wastage. The builders took just 46 hours to finish the main structural components and another 90 hours to finish the building enclosure. All of the structure is soundproofed and thermal-insulated. They even have air quality monitoring in every room given the pollution problem in China.

While the men didn’t work all through the night, they often worked until 10 p.m.

Time-lapse video: Previous record of building 15-story structure within 6 days


Finished: The 30-story Ark Hotel in the Chinese city of Changsha was built in just 15 days


The plot: The empty land where the hotel would rise after 360 hours


The high-rise rocketed up in a matter of days. It was built by Broad Group, a Chinese construction company which specializes in sustainable architecture



Steady: The sections built off the site are maneuvered into position by men who worked until 10pm every night


In position: Workers fit the units which can withstand a massive earthquake.


All of the structure is soundproofed and thermal-insulated and each room has air quality monitoring.

Selected comments by Chinese netizens on Sina Weibo

随风南渐:15 days is time for assembling. From design to manufacture of parts and units, and to final assemble, it still needs 1 year or 2. Modular steel structure is the fruit of science and technology, and is also the trend of future architectural development. But novel things are always questioned in all respects. Just let time test it!

CalifoRock:The toy blocks are stacked so nicely~!

猫狗潮妈:Mind-blowing! If every Chinese were capable of such efficiency, the would would belong to China!

慕莎mushay:Awesome! But I wonder if it is the next tofu-dregs (jelly-built) project.

刘霄露-半推半就的民和主:Absolutely high-tech! Has rewritten world architectural history! But the measurement for PM 2.5 indoors reaches 46!

且听风吟105:Is the building really in a hurry? Is being fast necessarily good?? Why I have aversion for the news at first glace, and associate it with unrealistic and grandiose ambitions immediately!!! Seems safety and quality of the architecture are the most crucial part?

盼盼张-丽江:It has my full attention: does anyone have the nerve to move in?

ndqwp:Pure modular steel structure? …Fast, light-weight, and horrifically costly.

晨北的微博:“Sir, the hotel rooms are fully booked. However, please wait a moment…We will immediately build another one next to us. May need 2 hours.”

长毛的菲菲:What I lash out at is not about if this thing is theoretically viable, but the PR offensive filled with flighty and rash utilitarianism and political ambitions. No one actually even cared about if the architecture itself is safe or not. 

上海同城会: Hope that I won’t hear about this building in the news later..

honey夏雨鱼薇特:Pre-fabrication is a good idea. But the term “History rewritten” really makes people feel uncomfortable. Is rewriting history really that important? Wait to brag about it until the observation period is over~After all, it is a “Made in China.”~ Its quality is really a concern~ Another vanity project~ [左哼哼]

CiphG:They say it can withstand (natural disasters) that do not occur even in some years (Chinese expression, meaning the biggest in terms of magnitude in some years), but when it does occur, they equivocate or resort to subterfuge.

yuhfgugu:So scary! Like stacking toy blocks. Feels very unreliable.

RON-GORGreat Leap Forward

hellotiger08:The Europe and the United States mastered this technology long ago. But they won’t make an effort to set the so-called record in speed. Their priority is that buildings’ structure is safe!

刘畅real:This is too awesome. What about its cost and safety? Can it be industrialized on a large scope?

星月朦朧:It is really pointless to go after the so-called fast speed. Is your hotel really in a hurry to open for business?

甜甜甜甜甜啊丶:This is entirely made of steel. If there is lightning, isn’t this one a super-size lightning rod? [奥特曼]

梦想皆有神助2011:Chinese speed. Don’t have the nerve to imagine how its quality is. I suggest that the government give it a try by moving offices in and working inside first.

Muriel_蚊:How many materials and how much manpower were expended in order to achieve this kind of speed? It seems that they didn’t even use any concrete.[吃惊]

歸隱山霖:Novel structure. Low carbon emissions + environmentally friendly = high cost. A standard for luxury architecture in the future.

DJ刘薇: Well…[汗]I am not opposed to birth of advanced and innovative technologies. But, please never treat people’s lives as lab rats. Wish I would not jinx this one. Wish this were truly the world’s No. 1… [兔子]

枫扬亚丁:I strongly advocate that the administrative heads of this county move in first!

    Remarkable speed, a great find, Jing. Keep up the good work!

    I know I wouldn’t dare to live in that hotel.
    Would you?

    Yup. It’s another disaster in the making. Where can you hide when transport, buildings, and even ‘outside’ are dangerous?

    I’ve witnessed similar marvels of building speed while I was in China. The building I witnessed were using a lot of substandard materials including “concrete” (honestly I don’t know what it was made of) blocks that literally crumbled in my hand as I examined it.

    Don’t be surprised if buildings like this come down even more quickly then they went up.
