Hello, engineer powers, I have a question: Is there someone who put crane foundation in the middle floor on the building? It's not placed on Building foundation, crane foundation will be on the 3th floor above the ground zero. They want to re-support the foundation till the Building foundation, but still is there some practical advises? What I should expect, what i should be very careful about ? Okey just to clarify my boss want crane to steps on Foundation about 120cm thick on 4 columns from the building 40x40cm 6m to 6m between columns.
