HBIM for a Coordinated Renovation of Historical Assets at Risk

Abstract. Italy is a territory with strong needs for joint actions for maintenance interventions on historical architecture assets that are part of the Cultural Heritage. The need for digital documentation plans as conservation projects for endangered sites has a particular urgency for those assets that, divided among different owners, risk multiple interventions in an unregulated manner, with the result of waste of time and public money. The specific case deals with a project whose aim is to optimize a renovation and maintenance intervention of a farmhouse that is part of an asset with multiple public owners, which uses not only digitization and modelling techniques in scan to BIM processes but also optimizes and automatize the information exchange processes between the elements of the same asset; the aim is to improve interoperability for maintenance and restoration processes to be managed by different and not always skilled stakeholders. The proposed workflow propose a method that can also be exported in large assets optimizing processes. The case study used deals with one of the several neoclassical farmhouses spread throughout the large, monumental park of the Reggia di Monza in Lombardy, Italy, Cascina Mulini Asciutti. The farmhouses are currently owned by a consortium participated by several public entities and present numerous grades of degradation and the necessity of important maintenance interventions.
