The inspection and monitoring procedures, referred to the joint activities developed in the period 2020-2023, had been executed using an integrated operational framework (Figure 2) designed to ensure the ongoing quality (homogeneity and robustness) control of the inspection process, see Petti et al. (2023).

In particular, regarding the managing corporation, the involved resources include the Head of Surveillance (HS), the Contract Manager (CM), the Internal Inspectors (IT), and the Internal Staff offices (traffic-TO, mobility-MO, maintenance-MAO), among others. As for CUGRI, the resources encompass the Legal Manager (LM), the Scientific Manager (SM), the Technical Contact (TC), the Scientific Contact (SC), the Inspectors (I), and the Contact person for safety aspects (CSA). On-site activities are executed by four groups of inspectors (GI), each consisting of at least two or three inspectors and a group leader (GR), under the coordination and review of a group scientific responsible (SR). Inspection activities are planned quarterly, with specific schedules determined every two weeks by the scientific coordinator (CS). All surveillance activity results are managed through a Bridge Management System (BMS) platform, enabling the managing corporation to access real-time information regarding the overall network's structural condition. The BMS platform is integrated within the Information System (IS) of CUGRI and it is managed by specialized technician (IT). The IS also has the capability to collect and represent monitoring data for the management of bridges and viaducts with medium and medium-high Overall CdA. In 2024, once the implementation phase of the surveillance process according to LG20 has been completed and the operators has been trained, the CUGRI support to the Surveillance Activities has been structured into (A) Scientific Support to Surveillance and (B) Control, Validation and Certification, as described in the following:

(A) Scientific Support • The support for the management of the results of the surveillance process; • On-site training of the managing body's inspectors; • The support in the monitoring systems design and data analysis.

(B) Control, Validation and Certification • First Level AUDIT activities on Inspection Process; • Validation and Certification of inspections reports, intervention/project typology sheets and eventual updates to the manual, Levels 3 and 4 structural checks; • The support in Extraordinary Inspections and verification of the factual conditions with specific laboratory investigations.
