Multidisciplinarity and accessibility in heritage representation in HBIM Casa de Santa Maria (Cascais) — A case study

Abstract

We are living in a moment of growing social awareness about the value of cultural heritage, the symbolic bequest of human evolution, possibly as a result of the equally growing notion of its vulnerability. Material and immaterial goods are classified as heritage when their historical and cultural importance is recognized as identitary. This title acts as a disseminator, but it must essentially serve as a protector: it is the human responsibility to create, safeguard and preserve heritage. As far as architectural heritage is concerned, safeguard derives firstly from its rigorous documentation, nowadays manifestly insufficient. In analyzing the methods of architectural representation of contemporary projects, we find, among others, Building Information Modeling (BIM) - an integrative, multidisciplinary, precise technology. Logically, in order to document architectural heritage, these same qualities are crucial, to which many more must be added. Therefore, the concept of Historic Building Information Modeling (HBIM) has emerged, currently at an early stage of widespread implementation. For this reason, the presented research seeks to contribute to the recognition and dissemination of the method. The advantages, which largely outweigh the obstacles of the process (also indicated), are evidenced by practical experience - HBIM representation, through the Autodesk Revit 2020 Software , of Casa de Santa Maria , in Cascais, Portugal, designed by Raul Lino. The aim is to demonstrate the potential for integration and communication of various geometric and non-geometric data. Noteworthy is the result obtained regarding the dissemination of the three-dimensional model, with the creation of a website which integrates a viewing platform. • HBIM is the digital multidisciplinary registration of heritage architecture. • Cultural dissemination and functional advantages are HBIM's goals. • HBIM offers a unique capacity of joint documentation. • Complete democratization of access to architectural heritage is expected.
