90-day China skyscraper going ahead “as planned”


Broad Sustainable Building (BSB) insists it will deliver its 220-storey Sky City in China, set to be the world’s tallest building, within the targeted 90 days, rather than in 210 days as rumoured by the media.

Supposedly designed by engineers that worked on the Burj Khalifa, Sky City will achieve the target by using BSB’s 95%-prefabricated modular technology at the astonishing construction pace of five storeys a day.

Juliet Jiang, senior VP of Broad Group, has said that the company’s plan to construct its 838m skyscraper by the Xiangjiang River in Changsha city “will go on as planned with the completion of five storeys a day.”


Broad, which has built a total 20 structures in China, demonstrated its rapid construction method to a wider audience in January, when the company constructed a 30-storey hotel in just 15 days.

Work on the foundations is expected to go ahead by the end of the month, while the planned three month construction period runs from the end of the year to the end of March 2013.

“We have not issued any press statement on this and it will go on as planned … we have not said anything about 210 days,” said Jiang, adding that the company is still waiting for project approval from the Chinese government.

Sky City has been designed to house 31,400 people in its luxury and low-income communities. Residential area will occupy 83% of the tower, all serviced by schools, hospitals, offices, shops and restaurants within the building.

The structure will be constructed using approximately 200,000 tonnes of steel, and will be built to withstand earthquakes of a magnitude of up to 9.0 on the Richter scale, and to resist fire for up to three hours.

Environmentally radical, Sky City will also be equipped with 15cm thermal insulators, four-paned windows, fresh air heat-recovery systems, and a host of other equally eco-friendly features.

Perhaps the boldest claim is that the cost of the construction of Sky City will come at less than $1,500 per m2 – a tenth of the cost of the Burj Khalifa with its $15,000 per m2 price tag.
