Know about the Top down methods in Construction
https://www.constructioncost.co/top-down-construction-method.html
Buildings with subterranean structures are typically built using the bottom-up approach, in which sub-structure and super-structure layers are built one after the other, beginning at the building's base and proceeding upward. It is unsuitable for projects with limited construction time or space. The top-down building technique is the solution to these problems.
