Description
When it comes to risk management of the very diverse Italian infrastructures – notably concerning bridges, viaducts, and overpasses, most of which were built between the end of the Second World War and 1980, with only 15% less than 20 years old – the national scenario is quite heterogeneous, since ownership, if verified, pertains to different managing bodies and each of them employs its own maintenance procedures. Therefore, this paper presents an approach for the systematization of highway bridges, viaducts, and overpasses and the related inspection data by conjugating the requirements of the Italian reference framework consisting of LG2020 (the guidelines for risk classification and management, safety assessment, and monitoring of existing bridges), the ASPI (Autostrade per l'Italia) Handbook, and AINOP (National Information Archive of Public Facilities).
In particular, a procedural workflow has been developed and tested on the infrastructure artworks on the A3 section connecting Naples, Pompeii and Salerno, included in the C.U.G.RI. ("Centro Universitario per la Previsione e Prevenzione Grandi Rischi") – S.A.M. ("Società Autostrade Meridionali"). Working on the pilot case of the Olivieri Viaduct, dedicated descriptors were developed and subsequently implemented as custom "parameters" in the BIM environment to meet the cataloging requirements for each structural component into which the infrastructure has to be decomposed following the specifications of the regulations.
In addition, the digitization procedure involving two types of operators – modelers/inspectors and supervisors – has been further optimized by developing ad hoc VPL (Visual Programming Language) scripts for the automatic assignment of classification data and inspection forms, and to establish a direct link between the information model developed in the editable BIM environment and the monitoring platform designed by C.U.G.RI's IT engineers.
