analysis and check results without requiring the specific FEM software used, as they could retrieve them directly from the collaborative platform. Based on the results of the structural analysis, the designer has the option to proceed with structural improvement or adjustment. In such cases, the BIM model proves to be invaluable for these activities. Conversely, continuous monitoring or periodic inspections, as dictated by the 'Attention Category,' will be carried out in accordance with the established guidelines. 3. Conclusions The new guidelines provide a structured procedure for managing the safety of existing bridges to prevent damage. This procedure comprises three key components: asset inventory and risk classification, safety verification, and surveillance/monitoring. In particular, it elucidates how the 'Attention Category' fits into a comprehensive multilevel approach. Starting with a simple inventory of assets, this approach leads to the determination of a risk level. In cases specified by the methodology, a safety assessment is performed. The adoption of a multilevel approach for the management of existing bridges is warranted due to the considerable number of infrastructures in Italy. The complexity and associated workload of inspections, investigations, controls, monitoring, and verifications are managed by evaluating the actual need and urgency qualitatively and approximately, on a case-by-case basis. If the 'Attention Category' is determined to be at level High or Medium-High, it is recommended to initiate the construction of BIM and finite element models, potentially integrated into the BIM models. Promoting interoperability among all IT environments involved in the BIM process is crucial. This process requires specialized software, and in the current context, communication and interoperability functions with other software play a vital role in executing specific tasks, such as BIM modelling, analysis, and structural design of interventions. An innovative interoperable procedure has been introduced, featuring its characteristics and capabilities that align with the guidelines' requirements, involving both structural and infrastructural disciplines. A proof of concept has been presented to illustrate how this procedure aids professionals in fulfilling the guidelines' requirements. Innovative IT tools have been implemented to optimize the process, with new apps introduced to streamline data exchange. The digital BIM procedure has been shown to be applicable to various aspects, including data collection, 'Attention Category' determination, modelling, georeferencing, data integration and sharing, document management, classification, WBS generation and organization, structural and geotechnical analysis, and revamp design. The importance of the open format IFC has been emphasized to facilitate communication across diverse fields of interest. Several workflows have been meticulously described to elucidate the process and the role of each IT component in the proposed procedure.
