China Build a 15-storey Ark Hotel in 46.5 hours ( lessthan 6days )

Changsha, Hunan province, the country’s Broad Group showed off their rapid building technology by erecting a 15-storey hotel structure in just less than six days. Hailed by the name Ark Hotel, this structure was being worked upon by 200 workers who erected its framework in just 46.5 hours whereas the external cladding and internal non-structural surfaces were finished in just about 90 hours.

This was done with no compromise on the sturdily and quality of the building. In fact this project has reported 20% savings in cost as compared to what would usually go in making a 15 storey structure.

It can withstand a 9.0 magnitude earthquake and embodies several energy efficient technologies which puts it 5 times ahead than that of comparable buildings.

Some aspects which exemplify their energy efficient technologies :

• Triple pane windows,
• external solar shades,
  
• 6 inches of thermal insulation,
• heat recovery ventilation,
  
• LED lighting systems.

This rapid building technology stands out with its attributes like energy efficiency, reduction in material use and building waste minimization.

The Broad Group here holds plans to build 15 similar structures in China and and 30 more in other countries.
