The China International Trust and Investment (CITIC) Plaza is an 80-storey skyscraper in the Tianhe District of Guangzhou, China. Currently, it ranks as the 8th tallest building in China and the 16th worldwide. All Nippon Airways used to operate at the CITIC Plaza before moving to Tower A of the Victory Plaza. Now, without humans, how long will this tower last?
1 day after people: The sign on top on the CITIC Plaza goes dark, as the power grid of Guangzhou fails.
50 years after people: The glass has fallen from the building, leaving it a skeleton.
250 years after people: Two and a half decades of decay has weaken the floor supports. The 74th floor gives way and the building goes down in a pancake collapse. Guangzhou is now unrecognisable.
