|Eng. Fulvia Petri,
NPS® ZENITH is mounted on a rigid footing - as a function of column weight - at ground level. Since the alimetric height of the structure stabilises at this moment, it is essential that any earth sinking where the NPS® ZENITH device is placed is kept under control. To simplify correct column installation, it is a good idea to foresee their positions ahead of time and with precision, keeping in mind that hoisting a large column could prove not to be very easy.
