This project was conceived without seismic isolation system but, later, it had been necessary adopt this technological solution. This variation had caused considerable planning problems. Indeed, it was necessary adopt different diameter and thickness for each isolator. In addition the difference in height of the floors and consequently of the basement floor, had caused an additional problem. This problem had been resolved building some internal partition on the basement floor with reinforced concrete walls, in order to arrange each isolator at the same level.
