I work in downtown Atlanta, and they are doing some kind of work on top of one of the high rise buildings downtown with a big crane. I was wondering how they got that heavy of a crane there to begin with? Thanks ahead of time!
If they have more than 13 floors, in fact there is a 13th floor. People are just too superstitious for some buildings, like hotels to state them. It will skip from 12-14.
The tower crane is build on sections of steel structures from ground level, they build much higher than needed, so the protuding section at the top that houses the crane do not need to be removed all the times, that probably explains the cost of building. They probably start to remove the protuding section when it reaches a height which is easy for machinery to access.
they simply use the crane to build itself all the way up in sections . when its done the sections if they are in the middle our side become the elavador shafts
