Description
n the context of road infrastructures management, the development of an optimal and efficient maintenance plan is fundamental to guaranteeing a safety service for the users and an optimal use of the financial resources. For this purpose, an appropriate monitoring methodology becomes necessary to support the managing bodies in the network administration and to give priority on the interventions.
In 2020, CUGRI (Inter-University Consortium for the Prediction and Prevention of Major Risks) and SAM (Southern Highways Company) launched a project of applied research, currently ongoing with SiS-SPN (Stable Consortium SIS Scpa), for the development of a surveillance model to dynamically manage the A3 highway (southern Italy). In particular, this model is based on a multidisciplinary approach which involves expert judgments, periodically on-site inspections and instrumental monitoring, according to the Italian "Guidelines for risk classification and management, security assessment and monitoring of existing bridges", published in 2020 after the collapse of the Polcevera viaduct in Northern Italy.
The main aim of the activity is to develop a Building Management System (BMS) capable of integrating GIS, BIM, and each risk representations, involving on-site interdisciplinary inspections, multi-hazards and multi-risks approach, and monitoring data analysis, in a strong multidisciplinary context.
The paper describes the developed surveillance model and shows the preliminary results.
