MANAGEMENT

Detailed explanation-1: -Column and moment frame actions decrease as you climb a multi-story building. As such, column sizes (sometimes) also decrease. Architects like this, because it gives them more usable floor space on the upper stories. From a material standpoint, a smaller column uses less concrete, so it saves money that way.

Detailed explanation-2: -Piles or pilings are drilled down into the earth. Some skyscraper foundations go deeper than 250 feet. The depth of a deep foundation depends on how tall the building is.

Detailed explanation-3: -How deep is the foundation of a 5 story building ? For a five-storey building, a 7 feet (2.1m) deep foundation is needed.

Detailed explanation-4: -So, why do we need skyscrapers? The simple answer: more room for more workers, or in the residential frame, more residents. In line with rising population density, and advancements in engineering, height limits around the world are being revisited and revised to maximise space for commercial and residential growth.
