Scan-to-BIM aplicado ao patrimônio histórico: Sobrado Dr. José Lourenço, em Fortaleza/CE

Abstract

The preservation of architectural heritage involves fundamental conservation concepts, restoration theories, and intervention technologies. In the context of historical heritage, adaptive reuse and Building Information Modeling (BIM) stand out as essential tools for documentation and preservation. Digital technologies, such as laser scanning and photogrammetry, increase the accuracy and efficiency of data capture, allowing for the detailed conservation of these buildings. Historic Building Information Modeling (HBIM) adapts BIM to the context of historical heritage, enabling detailed modeling and efficient management over time. In this sense, this study aims to apply the Scan-to-BIM process to the Sobrado Dr. José Lourenço, focusing on the documentation and preservation of the building. To this end, it uses advanced techniques, such as 3D laser scanning and high-resolution photogrammetry, to generate a detailed HBIM model. The Scan-to-BIM process begins with the digital capture of the building through 3D scanning, generating a point cloud that represents the geometry and texture of the environment with high precision. This cloud is processed and refined in software such as Recap, eliminating interference and optimizing the data. BIM modeling is then developed in platforms such as Revit, where architectural elements are recreated based on the point cloud. The case of Sobrado Dr. José Lourenço exemplifies the importance of laser scanning in preserving architectural heritage, allowing for precise and detailed surveys, essential for documentation and future interventions. The technology has enabled the faithful capture of elements such as frames, volumes, doors, windows and ornaments, ensuring a 3D model aligned with the real building. In addition, digital preservation has enabled the creation of interactive virtual representations, expanding access to heritage and ensuring its historical integrity for future generations. Thus, the adoption of HBIM presents itself as an efficient tool to streamline and improve the process of documentation, monitoring and conservation of architectural heritage.
