Innovative Chinese Construction Method Has Global Implications

Chinese construction conglomerate "Broad Group of China" has devised a fast method of building skyscrapers and towers which is spreading beyond the borders of China, poised to move across South and Southeast Asia.

This Chinese construction company completed a 30-storey tower that currrently serves a hotel in Hunan province in 15 days. The video of this project had drawn the attention of millions of Youtube viewers since it was posted.

...“The building had passed the resistance test of a level nine earthquake. It conserves energy of up to five times compared with that of a conventional construction, and provides air that is 20 times purer than the traditional buildings through our innovative air purification system.”

The accomplishment is made possible because <93% of the building materials are manufactured in the factory. The company welcomes global franchisees to adopt this model and build such factories locally. In supporting the company's value to be green, the factory should be located no more than 500km from the construction site.

There are currently six factories in China in different provinces. Besides China, BROAD Group has also set foot in India. These franchisees have made full payment for the transfer of technology which costs US$34mil for a population of 10 million and US$50mil for a population of 50 million. _Star_via_NBF

Planned 220 Storey Sky City in Changsa

The Broad Group's method of quick-building high rise towers of reported high quality, may prove to be a big cost saver for the global construction industry.

But that is only the beginning. The Broad Group is moving ahead to design the world's largest tower -- which sounds very much like an arcology, or a self-contained city.

Broad Sustainable Building (BSB), a construction company based in Hunan, believers they can do the whole $628million construction in 90 days.

The building will also beat China’s current biggest skyscraper poster - the 632-meter Shanghai Tower.

The company has been quite quiet on the use of the building, but earlier plans in 2010 - when the building was going to be 'just' 666m, would be used to home 70,000 to 110,000 residents.

There is a track record for BSB, a previous 15-storey construction was put up in six days in June 2010 - and a 30-storey building in just 360 hours.

The key to their speed is prefabricating large portions of the buildings in factories - so technically most of the tower will be built before the first digger hits the site. _DailyMail

Over the past few millenia, the Chinese people have been noted for their inventiveness, industry, and engineering accomplishments.

While much of contemporary China's industry and infrastructure buildup may constitute an economic bubble of resource misallocation, it appears as if China's Broad Group has created a safe and very useful and economical way of building high rises and towers.

The ability to prefab large conventional buildings in factories may eventually be adapted to the prefab building of floating colonies, colonies in isolated areas such as polar regions, undersea habitat colonies, and even space colonies.

Once you learn to build self-sustaining arcologies, the basic logic of logistical planning and design remains essentially the same, regardless of the outer shape and configuration of the structure.
