^^^ Yeah, the needles in NYC are basically a giant stick made of rebar and concrete with a counterweight on top. It's really just a game of "how thick do we make the sheer walls and columns". Vista's massing is much more complicated and probably opens up an array of different wind loading or other challenges. The road, while somewhat complicating, is really not any different than a parking garage though, it's structurally the same as the garage floors around and below it. It's no more than a public passageway through a parking garage.

What I was referring to when I say they dig down in NYC is that they first have to clear down to the rock and then usually blast down into the rock a little bit to make a basement or garage.
