By End 2016, Over 43% of World's Skyscrapers Are In China

[AndrewJin]

Wuhan Greenland Center (636 m) in your city's CBD is expected to be done next year (2018). Once completed, it's gonna overtake Shanghai Tower (632 m), Makkah Royal Clock, Ping An Financial Center (599 m), Guangzhou CTF (530 m), Taipei 101, Shanghai SWFC (where I work), Hong Kong ICC and others, second only to Burj Khalifa.

Wuhan's highest building in history

This one, finished in 2007, 331m
I felt it was really high before.

No skyscrapers are not costly to build if you look at skyrocketing land price in city like Bombay. That is why now a days high and high buildings are build though people prefers to live (In India) on either houses or in low rise. In city like Bombay, floor rise price is Rs 100 per Sq ft which is not very high.

Let's not mention land costs, which is a compulsive factor, not at the own will of the developers. Skyscrapers are of course very costly to build, that's basic knowledge. The taller the skyscrapers, the more unit space required for common areas like elevator shafts, air conditioning, water, maintenance and other building facilities, not to mention extra costs required to reinforce against wind, seismic considerations, its own weight, pressure on building foundation. Take the Wuhan Greenland Center as as example, to address these issues, the tower uses a triangular floor plan that gently narrows along its height to provide extra stability that protects against intense winds and seismic events. Three large sloping steel-reinforced concrete (SRC) columns rise and join at the top of the building to form the 61-meter crown structure that rests above a glass dome. By omitting portions of floors and perimeter framing at different elevations, “slots” are created in the building envelope to provide a distinctive architectural personality while reducing wind loads on the structure. In this respect, the locations and geometry of structural components have been carefully optimized to not only provide strength and stiffness, but integrate seamlessly with the form of the building. The building is equipped with 84 hi-speed elevators, tower GFA is 303275 sqm, development GFA 570000 sqm, at an estimated $4.5 billion total costs of construction, i.e. cost exceeds $14800 per sqm of tower GFA, very expensive.

US need not build sky scrappers

to build skyscraper is not their compulsion and if they build they will build out of their will

So the question remains. Skyscrapers are indeed costly to build, so if there's no need, no compulsion, what kind of "will" is making them build many in New York and Chicago, but not everywhere else?

This region, near Wuhan Iron & Steel, used to be one of Wuhan's worst districts.
Now:

The height of African achievement
World's largest construction company to erect Africa’s tallest building in Nairobi
Published: 09.03.2017 George Tubei

Hass Group has today announced that it has signed a $ 200 million agreement with China State Construction Engineering Corporation (CSCEC) to construct the tallest building in Africa.

CSEC which is currently ranked as the world’s largest Construction Company plans to construct the tallest building in Africa in Nairobi’s business district of Upper Hill.

Speaking at the signing ceremony that was held at Kempinski Hotel in Beijing, Chairman of Hass Petroleum Group, Mr Abdinassir Ali Hassan described the signing as a ‘historic’ event and congratulated CSCEC on winning the contract after a long negotiation and tender process.

“It has not been an easy road. CSCEC went through a rigorous tender system which they won over ten international companies including European, Turkish as well as other Chinese competitors. Hass Group awarding the contract to CSCEC demonstrates a stronger growing economic partnership between the Chinese Government and the Kenyan Government, and is a testament to Kenya’s economic and political stability. This project will give CSCEC a majestic entry point into Africa.” He said​

Hass Group and CSCEC sign a Sh. 20 Billion deal to in Beijing last week for the construction of Africa’s tallest building to be put up in Nairobi’s Upper Hill Area. Construction is set to start in April 2017. (sokodirectory)​

Mr Li Mingguang, Vice President of CSCEC Overseas Operations added the project will put Kenya on the global map.

“This will be the tallest building in Africa and become a landmark in Kenya. It is sure to drive regional development, promote economic growth, and attract more investment and tourism into Kenya. China State Construction understands the importance of this grand project and is honoured to be chosen as the main contractor.” He said.​

The signing ceremony was attended by high dignitaries including the Counsellor of Kenya’s Embassy in China, Mr John O. Odipo, Vice Chairman and Co-Founder of White Lotus Inc., Mr Sita Ramachandra Raju Poosapati and Vice President of CSCEC Overseas Operations, Mr Zhang Zhiping among others.

Hass Towers, an iconic mixed use development is set to open its doors in 2020, in Nairobi’s business district of Upper Hill. Construction of the foundations for Hass Towers is due to start in April this year, when the project will be officially launched in Kenya.

Once complete, this record-breaking mixed use development project, designed to represent ‘the height of African achievement’ will stand at over 300 metres high with 67 story’s, effectively becoming the tallest tower in Africa; considerably taller than the current record holder, the Carlton Centre in South Africa (at 50 floors and 223 m tall). The building will boost of facilities such as Grade A offices, a 5-star Hilton hotel, plus a luxury retail and entertainment complex.

Kenya is one of the fastest growing economies in Africa and the world thanks to strong agricultural, tourism, construction and telecommunication sectors.

The location of the project is ideal as Nairobi growing financial hub, Upper Hill is conveniently located just 16km from Jomo Kenyatta International Airport and already international organizations and embassies such as World Bank and the IMF have set up their regional offices there.

World's fastest elevator hits stomach-churning speeds in China
Guangzhou CTF Finance Centre breaks world record
By James Billington Updated June 8, 2017 09:19 BST

The world's fastest elevator, which reaches stomach-churning speeds of 47mph (75kmh), is being installed in a skyscraper in China.

Built by Japanese company Hitachi, the super speedy lift is found in China's Guangzhou CTF Finance Centre and will transport occupants at a record-breaking 1,260 metres per minute, reaching the 95th floor of the 112-floor tower in just under 43 seconds. The planet's previous fastest elevator managed to hit speeds of 1,200 m/min back in 2016 but this latest test, conducted by National Elevator Quality Supervision and Inspection Center, clocked an even higher speed.

According to Hitachi, the technology behind the impressive engineering feat is a permanent magnet synchronous motor, a compact traction machine with stronger main ropes and a control unit that can handle the high speed.

More importantly, to slow it down it also employs a high-tech braking system with special heat-resisting materials. Hitachi has also thought about the issue of blocked ears caused by the rapid ascent or descent by featuring air pressure adjustment technology to reduce the changes in the elevator car's ear-popping pressure.

While the ride to the top will be a gripping 47mph, speeds on the way down are thankfully slower, with a claimed 600 metres per minute descent, the equivalent to 22mph.

China is no stranger to record-fast elevators, however. As well as claiming the top two fastest elevators in the world (the second is found in Shanghai Tower at 42.8mph, built by Mitsubishi Electric) it also has a total of five found in the top 10.

Hitachi has said it will use the technology of this ultra-high-speed elevator for future product development and to produce higher quality, safer and more comfortable elevators.

As Shanghai sprawls outward, architecture firm Sasaki Associates has announced plans for a farm that grows upward. The hydroponic vertical farm will be built amid the skyscrapers of China’s largest city. Like most vertical farms in use today, it will be dedicated to growing staple leafy greens such as kale, lettuce and spinach, according to Dezeen.

Space-saving is the aim of the project, Dezeen reports. Sasaki Associates intends the multi-storey farm to act as an alternative to the vast swaths of land — and associated costs — required for traditional agriculture. The project will also incorporate urban farming techniques such as algae farms, floating greenhouses and a seed library.

Vertical farms exist in cities worldwide, providing fresh produce, fish, crabs and other foods to residents in cities such as Anchorage, Berlin, Singapore and Tokyo. Advocates say that vertical farms have a reduced carbon footprint, use fewer pesticides and guzzle less water than traditional farming. Opponents argue that there are many unanswered questions about the practice, and question its economic viability.

Construction of the Shanghai project is expected to start in late 2017 as part of a new development — the Sunqiao Urban Agricultural District. The district will also feature markets, a culinary academy, interactive greenhouses and an education centre for members of the community.

Children in cities are so cut off from country life, that most don't understand origin of their food.
Projects like these will also bring about a closeness with nature for children and help them bond with mother earth.
Appreciate projects like these!

Yep I do look forward to it as well. Anchorage, Berlin, Singapore and Tokyo already got this, I'm very curious to see what a real vertical farm looks like. Gonna be in Sunqiao Urban Agricultural District (孙桥现代农业园区), located in far eastern part of Shanghai, a 4-sqkm experimental zone connected by Shanghai Metro Line 2, welcome to check it out when it's done!

I wish it a success. We can learn from each other and improve on the technology.

Food security is a challenge in the future as climate change and urbanization will affect our food supply. Using technology is the way to go for humanity to lead a decent life without backbreaking farmers. Urban farming can be huge boon for Singapore, a city state which imports most of our food.

30kg of daily vegetable yield in a space of 1500 sq ft, requiring only 3 people to harvest. Imagine having dedicated skyscrapers for urban farming!

Because the air temperature is controlled, we can also grow vegetables and fruits from different climates. We don't have to air freight them from Europe or America, which is expensive and less fresh because of the distance.

This should have been done long ago.

By having food grown in an urban environment, the waste of energy and transport cost is reduced substantially. People might question its viability economically but Chinese people always manage to figure it out.

Sasaki Associates might design the first ones but I'm betting that local players will quickly learn the techniques and technologies involved and indigenize it. Then go around selling them

the waste of energy and transport cost is reduced substantially.

Exactly, vertical farm is an example of how high-tech skyscrapers can bring efficiency to urban economy.
