This is such an incredible building! An interesting fact about the engineering here is that those big cantilevered concrete floors are mostly open inside- the concrete was laid over an array of metal "bubbles" seen on the lower right here which reduce the overall weight of each cantilever. They can then all be supported by just a couple of large crooked column running up the height of this side of the structure
