The Inspection team worked from time to time with the contacts of Italferr (the engineering company of Ferrovie dello Stato Italiane Group) with initial coordination phases in which operational procedures and feasibility of the investigation plans were discussed, optimizing the interventions and tests to be carried out according to the individual typological interventions, thanks to the well-standing and long experience of the team in the field of investigations. Geometric surveys and structural investigations were carried out on several types of structures, both on buildings and warehouses of the maintenance department, and on the works along the railway lines such as bridges and sub-via managed by Italferr throughout the national territory. In contexts sometimes prohibitive for the unique morphological conditions of the sites, where from time to time the most appropriate solutions have been found to be used, such as the use of boats to inspect and investigate pond piles, the adoption of work at night to limit the inconvenience attributable to the interruptions of railway lines.
