29: Preservation of Brazilian Modern Architectural Heritage Through Gis and Bim Technologies

Managing heritage assets at an urban scale is a complex task due to the unique characteristics of buildings and their scale. Technologies such as Historic Building Information Modeling (HBIM) and Historical GIS (HGIS), combined with digital scanning and 2D data, have emerged to address challenges. Although the integration between HBIM and HGIS facilitates the extraction and transformation of geometric and semantic information, issues such as data loss during software transfers and the need to adhere to specific standards represent significant challenges. This study focuses on the integration of HBIM and HGIS, using the Pampulha Art Museum, recognized by UNESCO, as the case study. An exploratory qualitative methodology is employed to develop the HBIM-HGIS model and present it through a web-based GIS viewer. The study explores various data integration methods, their advantages, and limitations, contributing to a deeper understanding of HBIM-HGIS integration and providing a foundation for advancing architectural heritage management.
