marina bay sands is a mega hotel in singapore, it is one of the tallest hotels ever.
1 day after people:the lights go out in singapore,the water fall inside turns off.
3 years after people: glass starts falling out of the hotel.
45 yrs after people:the suspended part of the top falls into the city.
100 yrs after people: by now the building has outlived the singapore flyer,but the boat shaped upper part becomes to much for the structure to handle.it collapses in a pancake effect for abit, but it then tips over sideways and crashes into the lower area, now only the towers and some of the lower areas remain.
350 yrs after people: finally,after 350 years the towers collapse into each other,causing the building's down fall.
