infraBIM modeling applications for design and maintenance plans. The case study of the "overpass 16" from the main renovation project of S.S. 372 "Telesina"

In the present work the project of an overpass will be analyzed, which will take place over the Telesina, specifically at km 39 + 099.The work has been developed in different stages, using different software (appropriate for each task) in each of them. In this way it has been possible to analyze the interoperability between them, as well as the benefits and limitations for the execution of an infrastructure project, as is the case.A 3D model of the project in question has been developed, achieving not only a model with visual purposes, but also an analytical model, where a structural analysis can be performed. Regarding this last point, no analysis has been carried out. After this, the modeling has been expanded to the 4 dimension, linking the overpass and its elements with a maintenance plan (once the bridge is finished), being able to access to information related to the tasks to be carried out, and to their schedules.
