HBIM data management in historical and archaeological buildings

Abstract

Recent technological evolutions in the acquisition and management of building data are offering new opportunities for digital reconstruction. At the same time, the BIM (Building Information Modeling) methodology, based on the implementation of libraries composed of parametric objects provided by the IFC (Industry Foundation Classes) standard, allows the design and management of data of existing buildings, and, in particular, historical and archaeological buildings. In the latter case, the great variety of Cultural Heritage (CH) distributed over the European territory, and the ability of BIM to cover the life of buildings or/and other artefacts from a geometric, descriptive, physical and static point of view, have stimulated the development of the HBIM (Historic BIM) modelling. The HBIM approach should consider the complexity of historical or archaeological buildings or artefacts, with particular attention to possible fragmentation or incompleteness of parts. In this work, different approaches regarding the survey, restitution and data management will be described, finalised to the construction of an HBIM model, considering different possible variables, emerging from different study cases.
