• Inspectors (I) who make the inspection. In particular, they are subdivided into four groups (GI), each one composed of at least two to three inspectors and a group leader (GR), coordinated and reviewed by a group scientific manager (SR). The overall process is subject to internal AUDIT activities shared by a Scientific Committee, made up of academics, with specific expertise in the field, and the managers of the managing corporation.

All the results of the surveillance activities are collected and managed by a BMS platform, in order to allow the managing body to monitor the state of conservation of the entire network in real-time. The BMS platform (Figure 3b) is part of the Information System (IS) of the CUGRI (Figure 3a) and it is managed by a specialized technician (IT). The IS is also capable of collecting and representing monitoring data for the management of bridges and viaducts characterized by medium and medium-high Overall CdA. In this regard, part of the authors developed and tested applications in complex conditions [Petti L, Barone F, Greco D, Zuchtriegel G, 2022]. Each bridge is georeferenced in a GIS platform and modelled in BIM, where each main component is represented to uniquely distinguish it. The BIM models of the bridges were developed with Autodesk REVIT software through a systematised procedure configured as an algorithm designed to simplify the entire process, called Scan-to-BIM [Sanseverino A, Messina B, Limongiello M and Guida CG (2022)]. The BMS platform development also involves the active partici pation of “ ACCA Software S.p.A ” in the research group managed by CUGRI. Thanks to this collaboration, the “Bridge Inspection” software, based on the “usBIM.platform” h as been developed. It is a digital collaborative BIM-based software that allows to assemble different models into a unique geographic vision, which is necessary to develop a multidisciplinary approach.

To the scope, each bridge component is identified by an alphanumeric code (ID) (Figure 4) that uniquely links the component to its inspection sheets, according to Annex B of the Guidelines [Ministry of Infrastructure and Transport (2020a)].
