system, type of road according to category, road network to which it belongs and traffic volume. The second category includes all the main characteristics related to the structural components that the work, starting with the type of bridge about the static scheme and spans, type, number and dimensions of deck, piers, abutments and abutments. The third category includes all information obtained as a result of inspections in order to assess the structural state of the works of art useful for keeping track of the structural condition of the work and planning subsequent maintenance. A structured database containing all the information previously described has been created, the functionality of this database is to track the work throughout its entire life cycle to keep a record of all new changes and additions as a result of continuous monitoring and maintenance carried out on the various works, this will also provide the information necessary for the risk analysis of bridges and viaducts as required by the Guidelines. The structured database is the key component of the suggested digital process, serving as an effective springboard for the ultimate objective of automatically creating "primitive" BIM models of the entire bridge stock. First data is loaded into the database, which includes information from digital surveys, data from in situ inspections, and design documentation. The database was made to be used by both experts who could change its features and content and non-technical users who wanted to use it to the fullest. An overview of the database architecture is provided in Figure 2.

Fig. 2 Database architecture

The database will span various domains to ensure some interoperability among participants in the definition process. There will be information related to structural characteristics which will enable assessments to be made from an engineering point of view around structures, this information will be augmented by additional data obtained from the construction of a GIS (Geographic Information Modelling) environment, which will enable the complex of works of art to be monitored in a network context. In addition, the database created in this way will be a valid and immediate tool to know the main information of a work to be used in the analyses carried out in the subsequent levels of the Guidelines for Risk Classification and Management, Safety Assessment, and Monitoring of Existing Bridges, with the aim to create a BIM model that will evolve in step with the new integrations taking on a more precise and improved appearance, as it is empowered by the new information that can be integrated in the future and allowing the integration of any missing data useful for the enrichment of the BIM model.
