Incredibly, the 102-story landmark Empire State Building that only took 410 days to build in the early 1930s is still lauded as one of the best examples of a successful commercial building project (ignoring the 5 unfortunate workers that died during construction).
The Chinese have now set a new standard in the efficient building of a commercial building with workers in Changsha, China building a 15-story hotel in six days!
"The Ark Hotel, constructed with optimal energy, material and time savings, was reportedly not only more efficient but cheaper to make. Industry experts said there was only 1 percent construction waste.A great achievement, however we would like to see the quality of the finish!
The sustainable hotel already had its foundation so construction workers only took 46 hours to finish the building using pre-fabricated columns and modules as well as modern construction techniques. Once the main structural components were completed, only another 90 hours were required to finish the building enclosure."
