When completed by the end of next March, Sky City in Changsha will be the tallest skyscraper in the world, standing at 2,749ft (838m) high, over 220 floors. And remarkably, they’ve not started building it yet.

It took Dubai more than five years to build the world’s tallest building, the 828mBurj Khalifa, but architects and engineers at Broad Sustainable Building (BSB), a unit of the air conditioning maker Broad Group, are confident they can beat that record.

Critics have pointed out that BSB’s construction company has never built anything taller than 30 storeys before, but the builders seem unworried.

BSB senior vice-president Juliet Jiang told Construction Week Online that the company’s plan to construct the skyscraper “will go on as planned with the completion of five storeys a day.”

Designed by engineers who worked on the Burj Khalifa, Sky City will achieve the target by assembling BSB’s 95 per cent prefabricated modular technology at a breakneck construction pace. Nine of the world’s newest tallest 20 buildings are being built in China.

Adrian Smith, the Chicago-based designer of the Burj Khalifa who is working on the Kingdom Tower in Saudi Arabia, said at a meeting of the Council for Tall Buildings and Urban Habitat in Shanghai last month that rapid urbanisation in China would fuel major expansion in tall buildings.

“There are 179,000 people moving into urban areas every week. Do they go into a horizontal or a vertical city? It’s a question of economics,” said Mr Smith. BSB, currently responsible for 20 modular structures in China, demonstrated the construction method to a wider audience in January, when it constructed a 30-storey hotel in 15 days.

Foundation work is due to start at the end of the month, once local authorities approve the project. The slowing economy in China has led to some skyscraper plans being shelved, but the economy is still expanding at rates unheard of in the West. In China there is still considerable interest in building skyscrapers that show the rest of the world that your city or your company has truly arrived.

Changsha is probably best known as the hometown of Chairman Mao Zedong. Sky City’s projected cost is four billion yuan (£400m). Builders will use 220,000 tons of steel, and the structure will be able to house 31,400 people.

The company says the residential area will use 83 per cent of the building, while the rest will be offices, schools, hospitals, shops and restaurants. People will travel up and down using 104 high-speed elevators.

Sky City will consume a fifth of the energy required by a conventional building due to what BSB says is its unique construction methods, such as quadruple glazing and 15cm-thick exterior walls for thermal insulation.When it is finished it will be taller than the Shanghai Tower, which was supposed to be China’s tallest building, at 632m, when completed in 2014.

There are 239 buildings taller than 200m being built in the country,. At the end of last year, there were only 61 buildings taller than 300m in the world, but in five years, China will have more than 60.

As 1 WTC Reaches Historic Height, An Effacing Empire State Building ‘Salutes’

As of today, as you probably already know, 1 World Trade Center reached the historic height of 1,271 feet, eclipsing the Empire State Building and reclaiming its place as the tallest building in the city. In honor of that achievement, the tower will be lit up red, white and blue tonight. The Observer asked Tony Malkin, owner of the iconic tower, what he thought of being No. 2 again.

“The world’s most famous office building, the ancestor of all super-tall towers, welcomes our newer, taller cousin to the skyline,” Mr. Malkin responded in an email. “We’ve watched you grow, and now we salute you.” He signed it as “Empire State Building.”

It is a fitting tribute, if also unusual, considering Empire State Building staff were told not to discuss its “cousin’s” ascent, according to New York magazine.

Meanwhile, Curbed had a rather amusing video of the history-making column rising to the top of 1 World Trade. It underscores both the banality and the eager emotions surrounding this milestone. We have waited so long for that column to be but into place, though it is still just a 26-foot-long piece of structural steel. This is just another construction site, but also the most important one in the world.

One World Trade Center, Now New York’s Tallest Skyscraper

This afternoon, One World Trade Center will pass the Empire State Building as New York’s tallest skyscraper, reclaiming the city’s skyline and reviving the race for height that originated in Manhattan but which was resolved with the building of the World Trade Centerover 40 years ago. In just a few hours, workers are scheduled to install the first column of the 100th floor of the tower’s steel frame, which will rise 1,250 feet in the air, peaking just 21 feet over the crest of the Empire State Building’s observation deck.

 Upon its expected completion in 2014, One World Trade Center will stand 1,776 feet and will become the country’s tallest structure, a title which currently belongs to Chicago’s 1,450 foot-tall Willis Tower (formerly Sears Tower). Much jubilation greeted the announcement for many reasons–the director of the Port Authority giddily anticipated the views from the tower’s future observation platform, while architect David Childs welcomed the progression of construction as a sign towards the eventual rehabilitation of Lower Manhattan’s urban life. Yet, today’s events can hardly be seen as a milestone, says author and chronicler of New York’s skyscrapers Neal Bascomb, who told the NYTimes that the construction is “kind of like competing against a ghost.”
