How did they put a 9-acre park on the roof?

• notatoad 12y ago
  they made a building that covers 9 acres and put dirt and grass and trees on top of it.

    Yes, obviously, but how is it possible for the building to withstand the weight of the dirt, grass and trees?

      If you design for 100 story buildings, you can design for a few story building with dirt on top.

        It's fixing the leaks in 20 years that's the problem. But I guess the building just has to outlast the company...

          Nah, we've gotten pretty good at sealing concrete. You put enough tar and landscaping fabric under there, it'll last a while.

      Grass and trees don't weigh a lot, compared to dirt, or earth, or water-laden earth. Compare a moderate snowfall of a couple of feet with a foot of dirt and some rainfall. But these should be zoned, yes.
