The Ark Hotel – Construction of a 15-storey hotel in 6 days in China (Video)

This time-lapse video is pretty cool.

A construction crew in the south-central Chinese city of Changsha erected a 15-story hotel in just six days. The foundation was already in place and a crew of off-site factory workers had already built the sections but, as the video attests, the complete structure was erected in just six days. Despite the fast pace, no workers were injured.

Details of the Structure:

  • Level 9 Earthquake Resistance: diagonal bracing structure, light weight, steel construction, passed level 9 earthquake resistance testing
  • 6x Less Material: even though the construction materials are much lighter (250kg/m2) than the traditional materials (over 1500kg/m2), the floors and walls are solid with surefootedness, airtight and sound-proofing
  • 5x Energy Efficient: 150mm thermal insulation for walls and roofs, triple glazed plastic windows, external solar shading, heat insulation, fresh air heat recovery, LED lighting, yearly HAVC A/C energy consumption equivalent to 7 liters oil.
  • 1% Construction Waste: all components are factory made, construction waste, mainly package materials, result from on site set-up only and amount to 1% of the total weight of the building.

Details of the Build:

  • 46 hours to finish the main structural components
  • 90 hours to finish the building enclosure
  • workers did not work through the night, they finished at 10pm each night
