3. Supervision of security conditions and use of digital tools The objective to be achieved in existing bridges and viaducts management is the use of an innovative methodology, which within a digital and automated context leads to the bidirectional integration of geometric, material, performance and structural information with the degradation conditions of the artifacts and active sensors. The management and monitoring model must therefore be able to simplify procedures by means of digital tools, with a view to saving intervention resources and environmental protection, through: • accurate digital surveys, as-built drawings and project specifications; • their organization within BIM models, able to support the precise description of degradations and the design of interventions, and to enable seismic, geotechnical and fluid dynamic simulations also with a view to increasing flows due to climate change; • the use of advanced sensors for the assessment of structural criticalities; • the loading of information within a Bridge Management System (BrMS) for the prediction of problems and interventions, also through Machine Learning tools. The first step towards which the Agency is heading is the definition of a procedure for the creation of BIM models with relative levels of information requirements for the purpose of digitizing visual inspections according to the procedure of the existing LLGG Bridges. The next objective will be to provide, in real time, technical back-office information to the inspectors. After setting up the database of geo-reported information models and modeling the "digital twins" it is planned to implement the methodologies to carry out inspection activities also using VR and AR, in particular for: • supporting to inspectors training activities: using both information models and VR simulation in order to create an educational environment in which to train inspectors; • introduce a remote inspection service with the dual objective of supporting field inspector activities with all the necessary skills of specialized back-office engineers, and to promote a first advanced experience of remote total inspection services, using remote inspection devices (such as drone, scanner, autonomous vehicle, remote video surveillance etc.).
