[Grandmaster TSE]

As the United States and China battle over the finer points of currency manipulation at the G-20 summit, American negotiators may want to take note of this startling testimonial to the productivity of Chinese workers: A construction crew in the south-central Chinese city of Changsha has completed a 15-story hotel in just six days. If nothing else, this remarkable achievement will stoke further complaints from American economic pundits that China's economy is far more accomplished than ours in tending to such basics as construction.

how safe is it though

[donjalapeno]

looks like they just did the exterior and some interior.....what about plumbing/electrical/safety checks/carpets/beds/toilets/baths/tiles/elevator and all that shit for all the rooms?

[flagella]

Safety and quality is definitely a concern, but you still can't argue with the fact that they completed this in only 6 days. But yea, I'd hope they spend some more time building to ensure that it meets all the standard.

[b0unce. [?]]

I'm guessing none of that stuff is built in yet, looks like they just constructed the base/core/structure whatever you want to call it. I think I would feel more comfortable knowing a building was built stable/safe rather than a speedy job :P

[Grandmaster TSE]

well they built all the rooms and stuff somewhere else and brought it in
which means all the electrical and plumbing is done for each suite and probably just has to be connected to the main sets

Faster does not mean better.

Here's a gem in Shanghai from a year ago:

Shanghai Building Collapses, Nearly Intact

In the weekend’s bizarrest news, a nearly finished, newly constructed building in Shanghai toppled over, killing one worker. As can be seen in the photo below, the 13-story apartment building collapsed with just enough room to escape what would have been a far more destructive domino effect involving other structures in the 11-building complex.

A building at the Lotus Riverside complex in Shanghai’s Minhang district collapsed, nearly intact, on Saturday morning The development, known as “Lotus Riverside,” has a total of 629 units, 489 of which have already been sold. Now buyers are clamoring to get their money back, and authorities are making efforts to reassure them. The assets of the project’s developer, Shanghai Meidu Property Development Co., have been frozen and the city officials said the developer’s ability to repay homebuyers was secure, according to a statement on the municipal government’s Web site (in Chinese). A hotline has been set up for Lotus Riverside buyers, and by Sunday afternoon, more than half of them had met with a group of lawyers and officials organized to help them negotiate with the developer, according to the statement.

Meanwhile, the cause of the accident is under investigation and nine unidentified people from the developer, contractor and management company have been detained.

A representative of Shanghai Meidu could not be reached for comment.

The disaster could reveal some uncomfortable facts about lax construction practices in China, where buildings are put up in a hurry by largely unskilled migrant workers, and developers may be tempted to take shortcuts.

According to Shanghai Daily, initial investigations attribute the accident to the excavations for the construction of a garage under the collapsed building. Large quantities of earth were removed and dumped in a landfill next to a nearby creek; the weight of the earth caused the river bank to collapse, which, in turn, allowed water to seep into the ground, creating a muddy foundation for the building that toppled.

The South China Morning Post noted that the pilings used in the Lotus Riverside development, made of prestressed, precast concrete piles, are outlawed in Hong Kong because they aren’t strong enough to support the kind of ultra-high buildings that are common in Hong Kong. But in mainland China, they are often used because buildings there are typically much shorter.

Quality problems have long plagued construction in China, though they seem to be more apparent in rural areas and smaller cities, not in major metropolises such as Shanghai and Beijing. When school buildings were flattened by last year’s massive Sichuan earthquake, a number of parents faulted shoddy construction for creating “tofu buildings” that fell while other nearby structures were able to withstand the impact of the quake. More recently, state media reported that several new dams along the Yellow River are in danger of collapse, a situation attributed to shoddy construction practices, embezzlement and unqualified workers.

the description in the video:

Level 9 Earthquake Resistance: diagonal bracing structure, light weight,
steel construction, passed level 9 earthquake resistance testing

6x Less Material: even though the construction materials are much
lighter(250kg/m2) than the traditional materials(over 1500kg/m2), the floors
and walls are solid with surefootedness, airtight and sound-proofing

5x Energy Efficient: 150mm thermal insulation for walls and roofs, triple
glazed plastic windows, external solar shading, heat insulation, fresh
air heat recovery, LED lighting, yearly HAVC A/C energy consumption
equivalent to 7 liters oil.

20x Purification: after 3 levels of purification, the purification efficiency
for fresh air reaches 95%-99.9%; air exchanged 1-2.5 times per hour, and
indoor air is 20x cleaner than out door air

1% Construction Waste: all components are factory made, construction
waste, mainly package materials, result from on site set-up only and
amount to 1% of the total weight of the building.

This is the first building in human history which combines almost all
environmental friendly, comfortable and secure elements. So, we call it:
Sustainable Building


very impressive....

[tofu1413]

that building is basically a fancier version of those modular worker houses i've seen in shanghai and rest of china..

[bengy]

Taking into consideration that China has a billion people, finding workers to keep a work site going around the clock is not hard.

[TheKingdom2000]

Taking into consideration that China has a billion people, finding workers to keep a work site going around the clock is not hard.

I don't think the number of people has anything to do with it.
In general, asian people are harder working. This is from personal experience at various jobs.

[bengy]

Obviously you have to work hard, because if you don't, there's a pool of a billion other people from which your employer can find a replacement.

[bcrdukes]

It's called superb project management.

There were homes back in I think the 70s ors 80s in San Diego which were built in 6 hours. These homes are still standing today being lived in without any problems.

[skyxx]

Actually, you'll be surprised as that DOES factor in to the speed of the building process. China has a lot of man power plus hard workers. Just these two points will aid in building more and faster projects. Heck If you head to Hangzhou, Chang Sha or any of the smaller cities, you can see 20-30 Condos/Apartments going up at once. Just because one bad structured building goes on the radar doesn't mean ALL of them are bad.

In order to keep the unemployment rate lower, they will try and employ as many people as possible.

[jstn86]

try paying the construction workers in the US/Canada for night shift = $$$$

anything is possible if you have a lot of money. you can easily do that in north america as long as the construction company and the contractors are willing to pay for it.

it's a totally different ball game. you just cannot compare China in terms of manpower and resource. they have unlimited amount of cheap labour and it's quite feasible to do that in china.

with the attitude of north american workers, unions, price of work and material, it's impossible to do something like that or remotely close to it.

cool video none the less.

[SkinnyPupp]

Faster does not mean better.

Here's a gem in Shanghai from a year ago:
Exactly. I've stayed in many hotels and apartments in China, and the workmanship is ALWAYS (not sometimes, ALWAYS) shit. Even "nice" apartments, gated communities, etc.

One place I stayed at was beautifully decorated, fully landscaped, managed, etc. But the drains in the bathroom weren't done properly, so after you shower, the entire bathroom is filled with water. :facepalm:

[604nguyen]

how many of you are in or have been in the construction industry?
the reason why this is not possible here is because we have something called "standards"
We have strict building codes, inspections, etc...
we employ "Tradesmen" , with proper training, not semi-skilled labourers that will work around the clock for sticky rice and wonton soup
we dont want our 26th floor apartment turn into a ground floor pile of rubbish in the event of an earthquake.
we dont want electrical fires while we're asleep....
and certainly dont want our upstairs neighbours, shit and piss seep through our ceilings because of a poor plumbing job.

[Hondaracer]

you couldnt build a house in 6 days in Vancouver [very possible hypothetically] because as the above post states, there are inspections, services, and utilities that have to be run/inspected as the process goes along

obviously the "inspector" is a part of the project management in this process

i think this building is pretty safe compared to others in China. it uses pre-frab steel so at least there is less room for measurement errors.

They could care less about how well the plumbing is or interior in China's development cities. All they care about is how the building looks on the outside so when people take pictures it looks like the region is well developed.

[RRxtar]

assembling a prefab building and building one from scratch are not the same thing


i can put together a desk from ikea in about 20 minutes with step by step instructions, but i couldn't build one from raw lumber that fast.

how do u know the pre-fab'd steel beams and columns were made correctly from the factory off-site?

it's easy to make "fake" metal. the modulus of elasticity of the metal and structural design/strength can easily be compromised for cheaper price. ;)

[ilvtofu]

A lot of the comments from some users here aren't getting the point. The highlight of the video has nothing to do with cheap labour and hardwork, it's about the prefab process. Think of it like ikea furniture, it's all made with holes/screws included and if you could put together a lego set as a kid you could easily put together a piece of their furniture. It saves space and materials but also ultimately money to do it this way, rather than to have a regular furniture store stock furniture that's pre assembled. As long as you properly design something so that your average joe could figure out, time can be saved dramatically and a lot of stress.

It's very cost effective to do things this way and it's not the concept of cheap/fast chinese work that the story is about.

[Mugen EvOlutioN]

in canada it woulda taken them 4 months to build that thing

[guesswho]

agreed, i recently went to china, changsha hangzhou shanghai etc, they don't know how to maintain it, they can build it really nicely, but they don't do renovations to keep it looking nice, after a few years it looks like a 20 year old hotel in vancouver

this. most apartments that are built here you only see 1 crane. and in china if you look at the timelapse you can see that they work 24/7 with like 7 cranes with the place filled with workers. whereas here they only work half a day or less. sometimes people arnt even working cause "parts arnt here yet". in china the rules are pretty strict too.

you can tell people in china work efficiently just from the roads. instead of digging up the old road and repave and all that (for example 41st ave right now) in china they have pieces of the roads already made (like lego pieces) and they simply just take out the old road and put in the new piece. job done fast and efficiently and they also work at night when traffic is low. whereas in canada they work during rushhours :rolleyes:

I hate those prefab concrete slabs on roads. They're similar to what the States have on the I5. Every couple seconds... thunk...thunk...thunk. Sure, I'm probably a bit more annoyed by 'em because my suspension is nice and stiff, but even when I'm in a stock car they're annoying to go over.

As for working at night time, it's not like they don't do that here. Sure, it's usually on roads like Hwy1 and 99, but that's because if you did road work on something like W41 you'd get a thousand complaints from home owners about the noise.

[LiquidTurbo]

Most people are making judgments about the building merely because it was built fast. Built fast does not constitute engineered poorly. They are not the same thing.

[Lomac]

Most people are making judgments about the building merely because it was built fast. Built fast does not constitute engineered poorly. They are not the same thing.

Especially when they used prefabbed sections and just bolted them together. But as someone mentioned earlier, if they were using raw beams and putting it all together at the site, it would definitely take much longer. The reason why it's usually not done here is because most of our roads aren't capable of transporting those giant built sections of steel, or if they are, there'd be too many complaints about roads being closed to accommodate the extra wide loads.

[Hondaracer]

you know how precise each one of those sections has to be to make a squared building?

pre-engineered metal framing HERE has a shit load of problems if not installed right, not to mention other pre-fabbed stuff like truss's etc. if they are not meticulously installed, your whole house is out of wack and walls and ceilings run into angled corners etc.

I'd say it's fairly safe to say that yes, this building is infact built poorly, the argument whether it's structurally sound or not is another matter, but imo to put together 16 stories over 6 days, theres no way in hell the time was spent on each floor to make sure you are level etc.

one floor in that building 1/8th of an inch off, causes the whole building to be off, and the frame being installed over 6 days doesn't have any additional flex or settlement once 15+ more stories are installed on top of it shortly after?

shit is garbage holmes

You know precise the pyramids are? Building those were a hell of a lot more difficult than this.

The fact is, we have no idea how theses modular pieces were designed. What if the building is structurally sound?

We have no engineering data at all so all we can do is speculate.

If you look at it from an industrialist specialization built standpoint you will see that to have the workers constructing everything and the same people assembling things in a dirty gravel pit is not going to garner the best cost:quality

Another fact of the matter is that there are a shitload of OLD buildings I know of in vancouver and also a long the pacific coast of the United States that weren't inspected when they were first built and have withstood earthquakes, rain, snowstorms, you name it. It's not that I don't believe in inspections but there are buildings that are living fact all over the world that have survived the test of time just because they were engineered properly.

Once again can we not go on to the racist path and say that Chinese are skimpy idiot cheapskates and focus on the point of the post which was to show us what can be achieved with prefabrication.

[The_AK]

I wonder what kind of work was done for the foundation, it seems like they just started building on a flat piece of land judging from the video. You can only see so much of it.

[LiquidTurbo]

^obviously the foundation was set prior to the start of the video.

[Alatar]

The entire building is steel pre-fabbed columns, rather than concrete and rebar. I'm not in construction, but I'm pretty sure I wouldn't want to be in the top levels of a building that was held together by bolts and nuts with everything just bolted/riveted to the frame. I'd feel a little better with some permanence and flexibility built into the building. :)

I'm fairly certain those houses were built by skilled framers who actually knew/cared about what they were doing, not slave labor.

As for the post on the last page about, "they obviously accounted for flex/settling" imo it's impossible to just "account" for settling when you have hundreds of thousands of pounds of steel stacked on top of one another over a 6 day period.., a typical house in Vancouver can be built on engineered fill and settle enough to shift concrete slabs over MONTHS, but of course a 15 story structure built in china couldnt possibly do that right?

:troll:

to argue that any structure of this magnitude is built with any sort of "quality" can be done in 6 days is just ignorance imo, a 4 story wood frame condo in North America can take years to complete, and still have many many problems with quality control, and these are people who supposedly know what they are doing..

[dangonay]

Not really that impressive.

I bet they spent over a year (or more) building the prefab sections and getting them just right. And how much time was spent with the workers training/practicing at assembling the various pieces before they even got the the site to start building? How many "rehearsals" did they go through?

OR

They could have built it like they do log houses. You assemble the entire building at the factory. Everything is built perfectly, all pieces are the right size and everything is square. Then you dis-assemble it, mark the pieces and ship it off to the construction site for final assembly.


I bet if you added up all the man hours they spent designing, prefabbing components, training workers and putting the building up it would be no different then just building it the "normal" way on site. The only way this makes sense is if they are planning on making a lot of these buildings and they are all identical. That's really the only reason to go pre-fab.


I'd put money that the next building gets built at a much more leisure pace, since they already have their propaganda video out of this one.

you are not getting the main point of what these builders are trying to prove. When have you ever seen ANY type of 15 level story being actually built in 6 days? Never...

With the # of auto-cad / mech engineers in China, im sure it will take them a week to re-design a new building similar to this method.

how is this a propaganda video? I would say it was a smart marketing video; just look at the # of viewers is gotten.... im sure there are tons of companies in and outside of china wanting to contact the construction company to start doing the same thing in their region. Especially for developing country wishing to expand their housing market. For developers, the faster you build, the faster you can get people to move in and get on with the next project.

[BNR32_Coupe]

first off, this would never fly in north america. labor wages are too high and workers have all kinds of rights that prevent them from working at the efficiency level these chinese workers go at.

now, the dangers of having a short window frame for constructing a building is the higher costs associated with the risks. for example, a non-conforming batch of window panes would set the project back by the amount of time required to reorder and receive the new panes. adding to this would be loss of labour wages allocated to the window pane part of the project (of course, they can be reallocated elsewhere, however, the labour resources will have to be spent again when the window panes arrive)

There is no point of the video except to convince people that don't understand construction or project management that the Chinese can do something the rest of the world can't.

Throwing a high number of AutoCAD engineers at a project does not mean you can cut design time down to weeks or days. If 1 man can build a house in 1 year, then 2 men could build it in 6 months. 3 men could build it in 4 months and so on. But only up to a point. Adding manpower to a job doesn't scale linearly - you can't have 365 men build a house in 1 day.

It's just not an efficient use of manpower to try and design and erect a building in record time. If you took all the people involved in this project and split them up into 10 groups and had them design and erect buildings, they would get more done than one large group. They could start 10 buildings at the same time, and even if it took longer to erect each building, they'd still come out ahead of the single crew trying to do things in record time.

Anyone in project maagement would understand this. It's been proven time and time again that throwing huge numbers of people at a project doesn't reduce the time to finish the project by an amount equal to the increase of the manpower (as I said, it doesn't scale linearly). In fact, in many projects it has been found that things actually start to slow down when too many people are involved (especially in areas of design).

That's why this is a propaganda video, not a marketing video. Marketing implies you're selling something that people can actually buy. Nobody would come to a company and say "hey, I need a hotel built in 2 weeks - when can we start?" because it could never be done. All this video shows is how quickly they could assemble something on-site.

As I mentioned (and you completely missed) they don't show all the costs involved or all the work done before they assembled the building. I'd still put money that the total cost to make this building is higher than normal construction methods simply because efficiency drops when large numbers of people work on something.


And it's not like this is something new. I mean, nobody in Europe, Japan or America has ever had the idea of throwing people at a project to speed things up. And nobody in Europe, Japan or America has ever designed anything pre-fab or used AutoCAD or other tools to cut design time. :rolleyes:

You should read books on project management and see actual case studies done. Then you'd see right through this video.
