Bridge Management System for Historic Infrastructural Heritage

Aggressive environmental conditions and increasing traffic volume can cause significant deterioration to many bridges. Following some accidents, including the collapse of the Morandi bridge, in the 2020 Italy have adopted “Guidelines on risk classification and management, safety assessment and monitoring of existing bridges”. In the last few years Bridge Management System (BMS) have been increasingly used by infrastructure owners, especially those systems, based on stochastic methods, which make it possible to define a condition ratio (CR) starting from periodic inspections of bridges, during which a specialist identifies defects and evaluates them according to specific guidelines. Various countries have developed their BMS, however most of them utilize a two-dimensional approach. A BIM model completed with information data is useful to management of a specific asset during its life. The proposed study had as its purpose the investigation of a possible BIM-Use for an infrastructure owner, precisely the monitoring of the degradation conditions of existing railway bridges. The functions of an existing software aimed at the purposes described above have been implemented in a BIM environment. At the end of this pilot study is possible for an engineer valorize in BIM environment each founded defect, when all defects are been censes, the technician run the automatic calculation of the two index that describe the situation of the bridge. An interesting future goals is the developing of an application that work on IFC models, that are the only models that can be purchased by the public administration in Italy.
