1. Introduction Archimede Srl and Sina SpA have been implementing decision-making tools for the management of infrastructure networks since 2001. The collaboration, established to use the data collected with the detailed Sina inspection methodology, has enabled the application of Bridge Management Systems (BMS) to the networks managed by the ASTM Group, including the BMS system developed by AASHTO (American Association of State Highway And Transportation Officials). Following the publication in 2020 of the Ministry of Transport Guidelines for the classification and management of risk, the assessment of safety and the monitoring of existing bridges - introducing, together with the safety inspection multi-level approach, also BMS and BIM modelling systems - the two Companies developed the project described in the article, which combines the experience gained in such areas and adopts a “multi level approach” also for BIM modelling. Beginning from a pilot project applied on few structures, results were then used for the bridges and viaducts of an entire highway agency company and is to be extended also to tunnels and other minor structures, toward an Asset Management System. One of the biggest challenges of the project concerns the safe management and maintenance of highways and of the entire road infrastructure network: the decision-making tool which is currently being developed takes advantage of visual inspection data to process the “health” indexes of the structures and economic indexes in order to select interventions in an objective, swift and safe manner. All of this with the aim of also guaranteeing minimum traffic interruptions and optimizing choices from a logistical point of view. Various factors including the age of the infrastructures, extreme weather conditions, increasing traffic flows, changes in use and progressive deterioration provoke the gradual deterioration of infrastructure networks. The need to carry out detailed and well-coded inspections and to perform repair work is therefore becoming increasingly urgent, considering the higher vulnerability to damage of the infrastructures. The pilot project has enabled the tackling of such challenges employing: • the inspection data that Sina has been collecting for over 20 years, via a well-established and objective methodology that provides databases with which to carry out more in-depth processing of deterioration indexes and thus choose “standard” maintenance interventions; • digital information management methods and tools to record deterioration indexes and represent them graphically on BIM models; • Business Intelligence algorithms connected to BIM models to create dashboards for the analysis, comparison and monitoring of Bridge Management index processing. The main purpose of the project was therefore to create a methodology to reorganize the information currently available in Sina’s BMS platform as a decision -making tool for: Inspectors, Technicians, Management bodies, Safety control agencies. The results a first pilot project are now being used with the objective of extending the data representation and organization methodology to the entire assets managed by Sina (road structures and infrastructure networks) as well as to other infrastructures with a view to developing an “Asset Management” system.

The pilot project: inspection Digital Twin, integration with “ Sistema Ispettivo Opere Sina ” (SIOS) and Bridge Management System indexes As mentioned above, the aim of the pilot project is to create a Digital Twin for inspection purposes thanks to the integration of the current and well-established Sina inspection system, whose information are based on SIOS within information models (BIM) drafted according to specifications suitably defined as described in the following.
