The purpose of the work is the description of the state of the places prior to the intervention, the tracing of the excavation works to be carried out in accordance with the submitted project and the documentation of the subsequent phases of excavation and restoration of the state of the places. Secondly, it was possible to calculate the excavation volumes and the volumetric entity of the piles of soil deposited in the area following the excavations.

Through the Total station and GNSS receiver, a network of fixed points (three topographic nails driven into the existing concrete pavement) arranged within the site area with sufficient stability to be used throughout the duration of the construction site was created.
These fixed points constitute a network on which it was possible to correctly orient the surveys carried out in the subsequent work phases.
​
The terrestrial laser scanner, on the other hand, provided a cloud of points which was used to reconstruct with the best precision the course of the land in the various phases of the construction site, while the drone provided photographic documentation of the places which, through appropriate treatments of the photographic data acquired, led to the production of detailed orthophotos of the construction site area useful for documenting the progress of the construction site.
