Description
Planning, maintaining and optimizing the resources in the field of infrastructural networks management entails complex decision management to be effective. The involved activities generally include compiling an inventory, carrying out monitoring and maintenance activities, and executing interventions to upgrade the safety levels to the increasing demands. From a structural and financial point of view, preventive monitoring help optimizing the asset maintenance. However, a major concern in this field is that the structural performance is usually described by visual inspection-based structure condition states only.
To adequately consider the actual structure safety level and the eventual progressive deterioration of the bridge or viaduct performance, the use of structural health monitoring systems is of paramount importance. In this framework, the Italian Ministry of Infrastructures has launched a large-scale plan, funded by the National Recovery and Resilience Plan, for implementing a dynamic monitoring system for the remote control of bridges, viaducts and tunnels of the main road system in Italy. This plan foresees the creation of an integrated inventory and risk management platform for 12.000 bridges/viaducts, the SHM equipment of 6.500 structures, and the information modelling of some of them. This paper, after introducing the main features of the national plan, reports and discusses some activities related to SHM of bridges and creation of a dedicated control room that Autostrada Brescia-Verona-Vicenza-Padova S.p.A., one of the leading motorway concessionaries in Italy and part of the Abertis Group, is carrying out.
