A hotel in China was built in just six days! This is the Arc Hotel located in Changsha.
The 15-story sustainable hotel already had its foundation prepared. By using prefabricated columns and modules as well as modern construction techniques, construction workers took just 46 hours to finish the main structural components and another 90 hours to finish the building enclosure. While the workers didn’t work all through the night, they did work until 10pm each night.
Here are some details about the hotel:
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.
20x Purification: after 3 levels of purification, the purification efficiency for fresh air reaches 95%-99.9%; air exchanged 1-2.5 times per hour, and indoor air is 20x cleaner than out door air
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.
China is really advancing these few years. Although smart construction like this is rare, it is nice to see some corporations trying to grow by being smart and not cutting corners.
