Management properties and procedures in the information model of the historic building HBIM on building facades

Abstract

Historic Building Information Modelling (HBIM) has become the ideal tool for professionals studying building conservation and restoration. The BIM model allows one to identify structural deformations following three-dimensionally resolved models. In addition, this methodology is specifically designed to register parametric construction models, as an information manager by adding semantic components to the model, including information on the different transformations of the historical artefact, and allowing continuous progress in the building's life cycle. In this work, graphic information and data related to conservation projects are compiled that allow a management of all the documentation integrated in the same Project, from all the disciplinary fields related to the heritage conservation and rehabilitation process. Specifically, from the geometric identification and the restoration documents, it is intended to develop an experimental application where both terrestrial laser scanning records and the use of image processing routines can allow automatic operations to monitor alterations in façades, in order to subsequent control by conservation experts. For this, a building with certain characteristics has been chosen, such as the Miguel de Mañara palace in the city of Seville. A building that has a main façade of 43.30 metres in length by 6.75 metres in height and, in which its façade rotates in an angled guideline to adapt to the urban planning of the time. The analysis is based on the applicability of two segmentation algorithms and the construction of the multilayer enclosure model where the different stratigraphies of the results obtained are exposed.
