Abstract
BIM is a methodology applied to the realization of design models applied to new buildings. To date,however, most of the building interventions as it happens in the field of cultural heritage are developed in theexisting. For this reason, scan to BIM procedures are improved and improved every day to make the use ofBIM easier. This document will describe the combination of different geomatics techniques used by theGeomatics Laboratory of the University of the Mediterranean in Reggio Calabria to create a BuildingInformation Model of a highway viaduct (infraBIM). In particular, we paid more attention to the scan to BIMphase through the segmentation of the point cloud using machine learning techniques that allow to obtain theconstitutive parametric elements of the 3D model. The model containing the geometric and physical data madeavailable by the ANAS management body in order to use the potential of infraBIM. This methodology today isof particular importance for the control, monitoring, intervention, and maintenance of road infrastructures,optimizing the procedures existing up to now. The advantages would be even more evident considering that weare living in a particular historical moment, in which a large number of bridges and viaducts in our nation aresubject to advanced forms of degradation
