This means we would expect a typical structure to fail once in every 500 to 1,000 years . New buildings are not only designed to not fail, but are also designed so that in the event that they do fail, they will do so in a predictable and desirable (or at any rate, the least undesirable) manner.

The earliest steel skyscrapers, like the Empire State Building, which date from the 1930s are least likely to remain standing in 7,000 years because they are constructed almost exclusively of steel, meaning they have exceptional tensile strength but are quite rigid and inflexible.
How long do modern buildings last?
While some buildings will last for more than 50-60 years without problems, some will start developing problems after few years of construction. The designs used in concrete buildings also play a part in how long they will last.
Can skyscrapers last forever?

Why do old buildings last longer?
Water destroys materials that are prone to rot — increased moisture content allows bacteria, fungi, and insects to survive and to use that wood as a food source. In old houses, they used materials that were more naturally rot resistant , such as old growth pine that are full of resins and natural chemicals.
How long will New York skyscrapers last?
This means we would expect a typical structure to fail once in every 500 to 1,000 years . New buildings are not only designed to not fail, but are also designed so that in the event that they do fail, they will do so in a predictable and desirable (or at any rate, the least undesirable) manner.
