Reply to comment by Edwunclerthe3rd in MTA spent twice as much on Second Ave subway consultants as it did on its construction by NYY657545

That’s just in the old parts of Paris. They put all the skyscrapers in a designated business district called La Defense.

What does this matter when we generally build subways under streets not skyscrapers?

If we were building a new line under WTC 1 then the height of it could be relevant.

My guess would be lateral/shear forces. Tall buildings are subject to a great deal of wind-related shear forces. If those forces lead to outward force being applied to sides of the foundation, then the ability of the ground surrounding the sides of the foundation to resist those forces matters.
