You can see the stairs on the left side at about 1:00. Make sure to view the video on youtube, and switch to HD. Alas, I could not make out any elevators. I wonder when they got installed.

It also seems odd that you can see *right* through the building after it is constructed... Unless it only has 3 units/floor, and those units have relatively open floor plans, I doubt its completely fitted out.

STILL, amazing.

Geeze, you don't ask for much do you??!?!?!

You've never heard of "roughing it"?

I do not believe that after 6 days all work was done. Only visible structural work at the exterior, which is visible from outside was done.
Similiar it is with many other prefabricated structures: it is estonishing how fast a wind turbine or a telecommunication tower built of prefabricated elements can be built. But in most cases there is still much work to be done after structural completion, before it is fully operational.

China Broad Group constructs 30 story building in 15 days


January 07, 2012

Read More: http://nextbigfuture.com/2012/01/chi...-30-story.html

We have been closely tracking China's Broad Group and their prefabricated factory mass produced 'Can be Built' skyscraper technology. Six months ago they had earthquake certified a scale model of their 30 story building. now they have built an actual 30 story building in 15 days at the end of 2011. This is one of the key technologies to watch for the next decade or two. The reason is the construction methods use far less cement and are more energy efficient. They will also enable faster urbanization of the developing world (not just China.) With state backing Broad Group will have this technology in use for more high rise commercial construction by 2020. This is part of the mundane singularity of technologies that mostly exist now and can high impact on the world.

The buildings are five times more energy efficient in operation and use about 6 times less cement. They plan to build one hundred and fifty 30-story apartment building, hotel, office plans using the new system. They have started building a 1.33-million-square meter “NO.1 Sustainable Building Factory” and it will be able to produce 10 million square meters of mass produced skyscrapers (about 100 million square feet) each year. The 30 story building is 183000 square feet so the factory can produce about 500 of the 30 story building each year and many more factories will be built.

The Changsha Broad Air Conditioning Company has unveiled designs for the 200-storey Sky City tower, a sustainable mixed use project. At 666 meters tall, the building will house 1.2 million square meters (12 million square feet) of space for residential apartments, retail, offices, restaurants, schools and a myriad of other facilities. The building will be manufactured in a factory and assembled on the construction site. Additionally, the tower will have the capacity for 70,000 to 110,000 residents. It will use 400 kilograms (1000 pounds of material) per square meter). 480,000 tons of building. Even with reducing the occupancy by half so that units are 1320 square feet instead of 660 square feet the amount of material is 12 tons per person for 40,000 people.

• Space blocks and all rooms remain at 20~27 ℃ all year round, glass wall enable
sunshine lighting up the streets.

• The clear height of residences and office is 2.8m, the clear height of space blocks are 5.6m, 9m, 12m respectively.

• Four 4meter wide streets start from the ground to the floor 121 at 400m, the total length of street is 12km, shops, agriculture markets, handcraft shops, restaurants, amusement parks, sports centers, natatorium, cinemas, opera houses, museums, libraries, training centers, schools, kindergartens, clinics, banks, police stations, etc. on both sides of street, same as city downtown. Botanical garden, natural parks, fishponds, waterfalls, sand beach can be found in some floors, same as the suburban.

• 16 large observation elevators and 31 high-speed elevators can serve 30,000 people every hour.

Safety

• Level 9 earthquake resistance, scale model will be tested by national authorized institution.

• BROAD unique technologies “diagonal bracing, light weight, factory-made” ensure the
highest earthquake resistance level with minimum materials.

• Trapezoidal construction structure corresponds the law of mechanics, which can withstand earthquake and storm.

• Sky gardens locate on floor 71, 121, 156, 176 and 191(12,000m2 in total), also function as the helipads, which are able to evacuate tens of thousand people during fire emergency, provide extra fire protection than conventional skyscrapers.

It's not like this new. Manufactured housing has been the next big thing forever. Unfortunately, nobody wants to buy it, which is why you don't see much of it (American view it as a fancy trailer).

I don't imagine buyers/investors are going to look to favorably on larger scale manufactured buildings, either. To say nothing of doing it in a way that meets code (buildings codes are not uniform in the U.S. - they're not even uniform from city to city). It's a neat model idea... but its not new, and it isn't like we don't already incorporate some of this into construction. I don't see it taking off, though. Too much institutional, government, and consumer weight against it.

This building appears to be designed to handle a peak ground acceleration of 0.78g which means it would have been able to withstand the Haitian earthquake which was 0.50g. And should therefore be of sufficient strength for moderate earth zones. This is remarkable given that this building was assembled in just 15 days.

But this structure is not of sufficient strength for earthquakes such as Northridge which exceeded 1.0g or the Christchurch (New Zealand) quake which exceeded 2.0g.

I don't think it will succeed in the US either but it will probably do well in other countries such as India, Brazil. I don't think Europeans will accept it either due to their negative experiences with Pre-Fab housing built after the WWII.

It definitely isn't new, and pre-fab is still around in many forms, but by and large it never took off in the US. Here in San Antonio we have a very famous example of pre-fab construction. The 496 room 21-story Hilton Palacio Del Rio was built in 46 days. In fact, the entire project, from design, to fabrication, to construction to occupancy took only 202 days. The concept was built for the '68 World's Fair as a high-profile showcase for modular construction, but it never went anywhere.

The rooms are basically square tubes of structural concrete that were stacked on top of each other around an elevator core. The fully furnished rooms were lifted into place by a crane-- to keep each room stable during the hoist a Sikorsky helicopter tail rotor was attached.

there isnt much pre-fab in Brazil. Besides, in Brazil, the materials are expensive. Pre-fab works EXACTLY on places where materials are much cheaper than labour. As first world countries. Or China, where BOTH are cheap, and the demand is something from another world.

Broad will be scaling up to 50 floors next.

China's high-speed building boom

"This is the tallest building in this county, and it's also the fastest-built," said Rong Shengli, one of the building's planners, looking over the rural sprawl from a helicopter pad on the hotel's roof. "Next we're going to build a 50-story building. Then a 100-story one, then a 150-story one. And they're all going to go up fast."

In just over nine days, builders in China's central Hunan province put up a brand new building ready to be used. The three-storey building was created from scratch using a system of prefabricated modules.

Had this type of high rise technology been readily available in the 50s and 60s it would have been used everywhere (the Alcoa Building look of pseudo industrial efficient architecture was 'hip' and there were huge demands for floor space in many US cities into the early 60s.)

If the US in the present, and, near future had the money and a huge demand for increased housing density, this would go.

However, we do not.

Instead, we need to build things that last. Why? Because buildings had better last a long time in good repair, or they will last a long time as a wreck.

Getting too expensive to replace much of anything, anymore.

Here is the PDF. Also 6 is a lucky number in China so the 666 meter height should be seen as something symbolic to the Chinese. Not to the average American like me though. However in feet this building is 2,185 feet tall. So it's a pretty huge building here, and they want to build this building in a year.

Tallest Building in the World - Sky City to be assembled on site in 90 days in Changsha, China from Nov, 2012 to Jan, 2013


June 14, 2012

Read More: http://nextbigfuture.com/2012/06/tal...y-city-to.html

Projected cost for the building is RMB 4 billion (US$628 million). Once completed, the 220-story structure will surpass Burj Khalifa to become the tallest structure in the world. The building will also outshine the 632-meter Shanghai Tower.

- Getting central government approval should be a simple matter for the company that built China's Shanghai Expo 2010 pavilion. In New York Freedom tower has already cost $3.8 billion and is not completed yet. Freedom Tower is looking at a late 2013 completion. Broad Group and factory mass produced skyscrapers was number 8 on my list of mundane singularity technologies. They plan to capture 30% of the world's construction industry, which will be achievable by dominating construction in China alone.

I think it is time Sky City gets it's own thread .

[MolsonExport]

Just returning from Shanghai, I was most impressed by their achievement in building the longest, and one of (if not) the most world-class metro systems, all in under 20 years. In my opinion, a singular achievement.

Meet the Man Who Built a 30-Story Building in 15 Days


09.25.12

By Lauren Hilgers

Read More: http://www.wired.com/design/2012/09/...kyscraper/all/

Zhang Yue, founder and chairman of Broad Sustainable Building, is not a particularly humble man. A humble man would not have erected, on his firm’s corporate campus in the Chinese province of Hunan, a classical palace and a 130-foot replica of an Egyptian pyramid. A humble man, for that matter, would not have redirected Broad from its core business—manufacturing industrial air-conditioning units—to invent a new method of building skyscrapers. And a humble man certainly wouldn’t be putting up those skyscrapers at a pace never achieved in history.

- So far, Broad has built 16 structures in China, plus another in Cancun. They are fabricated in sections at two factories in Hunan, roughly an hour’s drive from Broad Town. From there the modules—complete with preinstalled ducts and plumbing for electricity, water, and other infrastructure—are shipped to the site and assembled like Legos. The company is in the process of franchising this technology to partners in India, Brazil, and Russia. What it’s selling is the world’s first standardized skyscraper, and with it, Zhang aims to turn Broad into the McDonald’s of the sustainable building industry. “Traditional construction is chaotic,” he says. “We took construction and moved it into the factory.” According to Zhang, his buildings will help solve the many problems of the construction industry. They will be safer, quicker, and cheaper to build. And they will have low energy consumption and CO2 emissions. When I ask Zhang why he decided to start a construction company, he corrects me. “It’s not a construction company,” he says. “It’s a structural revolution.”

- Compared with the West’s elegant modular buildings, Zhang’s skyscrapers are aesthetically underwhelming, to say the least. On a tour of the T30, my guide gestures at a scale model and says, “It’s not very good-looking, is it?” To create a sufficiently spacious lobby for the hotel, an awkward pyramid-shaped structure had to be attached to the base. Inside, the hallways are uncomfortably narrow; climbing the central stairway feels like clanging up the stairs of a stadium bleacher. It’s worth noting, though, that the majority of apartment buildings going up in China are equally ugly. Broad’s biggest selling point, amazingly enough, is in the quality. In a nation where construction standards vary widely, and where builders often use cheap and unreliable concrete, Broad’s method offers a rare sort of consistency. Its materials are uniform and dependable. There’s little opportunity for the construction workers to cut corners, since doing so would leave stray pieces, like when you bungle your Ikea desk. And with Broad’s approach, consistency can be had on the cheap: The T30 cost just $1,000 per square meter to build, compared with around $1,400 for traditional commercial high-rise construction in China.

- The building process is also safer. Jiang tells me that during the construction of the first 20 Broad buildings, “not even one fingernail was hurt.” Elevator systems—the base, rails, and machine room—can be installed at the factory, eliminating the risk of a technician falling down a 30-story elevator shaft. And instead of shipping an elevator car to the site in pieces, Broad orders a finished car and drops it into the shaft by crane. In the future, elevator manufacturers are hoping to preinstall the doors, completely eliminating any chance that a worker might fall. While Jiang focuses on bringing Broad buildings to the world, her boss is fixated on the company’s most outlandish plan—the J220, a factory-built 220-floor behemoth that would just happen to be the tallest building in the world. It’s hard to say for sure that the 16-million-square-foot plan isn’t entirely a publicity stunt. But Zhang has hired some of the engineers who worked on the current height-record holder, Dubai’s Burj Khalifa, and Broad has created two large models of “Sky City”.

.....

Broad employees (here lining up for a morning briefing) have to memorize the chairman's advice on everything from brushing teeth to having kids.






Prefabricated skyscrapers can be inflexible. To create a lobby for this hotel, Broad had to stick an awkward pyramid onto the base.

Broad Sustainable Building (BSB), a subsidiary of the Broad Group based in Changsha in Hunan province, China, insists that it will deliver its 220-storey Sky City within the targeted 90 days, rather than in 210 days as rumored by the media. The 90 day assembly schedule does not include time to complete the foundation, but the time to assemble all of the floors.
