DEVELOPMENT OF AN INTEGRATED BIM-GIS MANAGEMENT TOOL FOR MAINTENANCE PLAN OF HISTORICAL HERITAGE

The planned maintenance of cultural heritage (CH), in recent years, has been strongly supported by innovations in the digital field and, in particular, by digital models. In this framework, Main10ance, an INTERREG project, aims to implement a plan of maintenance and conservation of the historical cultural heritage. The case study is the system of the Sacri Monti of northern Italy and Switzerland, groups of chapels and other architectural artefacts. The design phases are divided into: survey of the historical architectural heritage present; data processing and realisation of three-dimensional models with the help of BIM software; integration of the same in the geographical context through GIS support; creation of a database (DB) which creates interoperability between the various domains and which collects information on the characteristics of the heritage for maintenance and conservation purposes; possibility to make the information associated with 3D models accessible through demonstrators that allow interrogation of the DB and the models themselves. The data have been entered (planned maintenance records, history of activities, etc.), convey them into the DB structured according to the INSPIRE Directive (2007/2/EC, Infrastructure for spatial information in Europe) and CityGML standard with its Level of Detail – LODs) for the GIS representation and IFC for the BIM. The Italian National Unification (UNI) norms have also been considered for the DB design.
