^^^ I'm not an engineer, but I'm not sure there is any way to answer that question. The best answer is: They are different.

This is a huge footprint next to a multi level roadway that will have connections through the building. Compare that to the needles they are building in NYC which have a tiny site often excavating down deep into the ground (rather than just building up from here).

So on one hand you have tons of room to maneuver on this site, but complications like roadways running through the site or cassion foundations. On the other you have extremely tight sites for extremely narrow buildings, but it's also a much smaller floorplate and there's no roadway to worry about.

So they are totally different types of complexity, but that's what engineers do: find the best solution to each project's unique requirements.
