WOW, no way though, the number is just way too incredible, but there's no doubt the city is the one with them most cranes.

yes lots of cranes, its true, but the 30000 number is just impossible.

if you give a 30m per 30m space to each crane, times 30k, thats 27,000,000 meter squares, 9 km per 3km filled only with cranes.

impossible, maybe 2000 or 3000, and thats an incredible number.

Shanghai has been building at a higher rate for a quarter of a century. The difference is that cranes are not as visually prominent because there are actually *buildings* built and was not a complete desert a decade ago.

The point, is that these "analyses" are not accurate. Fodors and other sources claim that Shanghai has 25% of the world's cranes. Tell that to a crane manufacturer and he will tell you that it's all poppycock.

Morgan Stanley economist Steven Roach from a May 16, 2006 article in Businessweek regarding Shanghai:
"Though it represents about 5% of the world's economic output, this hungry dragon devours about 20% of global aluminum, about 30% of steel, iron ore, and coal, and 45% of cement produced each year"

the number is EASILY possible.
30000, yeah, 9 x 3 km, that is easily possible, if u want to say it like that.


what might be wrong is the percentage given, but we heard figures ranging from 12 to 23% quite often now.

well, what is the purpose of the thread, no matter what the percentage is, no other city has such massive development going on like Dubau.

30 000 Cranes? Hardly believable. Remove a zero and a thousand you might be getting close to the real one. Some shots that Krazy posted are of the same locations but at different angles. There are no more than 100 cranes in those pics.

Shanghai is also around that crane number as Dubai or perhaps more. I mean its annual increase of population stands at 350 000 with official measures. Imagine the unofficial which might put it around half a million per year. Do you think these people live in tents? No they live in apartment blocks. So you will need around 600 apartment block towers being built each year to keep up with demand.

Its common sense.

9 by 3 filled only by cranes, no buildings, no roads, no nothing. You could do that in the desert, but its hardly believable in the city.

most of the projects in dubai are built in the desert, on barren land.

it is possibly.

30000...

I can't see there being only 125,000 construction cranes in the world.

ok im not here to argue that they have or don't have that many cranes, my argument is why do they have some many cranes on top of each other, in all of those pics there looks to be an overabundance of cranes more than whats needed, they have about 20 cranes where 10-12 would do.

I counted about 130 cranes in those photos of Dubai and some of the photos show the same cranes.

By comparison, I counted 37 Tower Cranes operating here in Las Vegas right now, but they haven't installed the tower cranes at MGM Project City Center yet, which will need a bunch.

there was an article in an Aussie paper last week about booming Dubai and what it means for Australia. In year 2000 there were 4,500 workers from Australia with work visas over there. Today there are 15,000! Alot of aussie companies are setting up over there due to the many years of work ahead. its all good.

According to Emporis there are 310 skyscrapers under construction. So 30 000 cranes is 100 cranes per listed scraper. Or perhaps 10 unlisted scrapers for every listed scraper, and 10 cranes per each scraper?

Another angle to try and verify/dispute the claim:

Current scrapers under construction in Australia's biggest cities:

Sydney 20
Melbourne 12
Brisbane 13
Perth 10
Adelaide 5
Gold Coast 20

Fairly puny individually when compared to Dubai. When added together it is 80 scrapers, which is 1/4 of those listed on Emporis for Dubai. Does anyone know how many in Dubai are unlisted?

America has 10x population of Austrlia, so they probably have 800 under construction (very rough projection I know...)

Now for some of China's biggest cities according to Emporis:

Shanghai 25
Beijin 58
Hong Kong 150

Others have stated Shanghai has 600 under con. So I'd assume the chinese figures are totally unrepresentative (are Dubai's any more accurate?). Conservatively say Hong Kong has every scraper reported, and that the top 5 cities each have as many scrapers under construction as Hong Kong. And that there are no other scrapers under construction in China. This means 750 under construction in China.

So 880 in Australia/US, 750 in China. Total 1630. Which is around 5 times what Emporis lists for Dubai.

Then make an even wider guess that the number of scrapers in Europe/India, South America etc, is more than 5 times the total number of unrepored scrapers in Dubai, meaning that Dubai has less than 1/6 of the scrapers in the world under construction.

Anyone able to firm up some of my wild guesses into a better approximation of the facts?

My estimation is that the Emporis numbers for underconstruction are totally wacked / inaccurate for cities in mainland China and for that matter all of Asia: Singapore, Manila, Dubai etc.. (cities in Asia build highrises like multiplying bacteria, really there is no comparison in building rate between these cities and cities in the Americas).

Shanghai probably has way more U/C than Hong Kong. Guangzhou, Tianjin, Wuhan, Nanjing, Shenyang, Shenzhen and Chongquing probably have a few hundred each U/C as well. All of these cities have at least double the population of Dubai (over 3 million people) and a pro-highrise development philosophy. I highly doubt that a city of 1.5 million will have even 1/4 of the construction of a country of 1.3 billion people with cities growing by 10% per year and a migrant worker population of 80-120 million.

Beijing





The reason why most people assume Dubai is the most active city worldwide is because yes, it does have extravagant projects, but also because China is only partially represented on the forums.
