Case study: Casa da Camara de Guimaraes. HBIM modeling from non-destructive techniques

This study focuses on the application of HBIM (Heritage Building Information Modelling) for the comprehensive monitoring of the structural health of the Casa da Câmara de Guimarães, Portugal. To carry out this comprehensive assessment, advanced inspection techniques were employed, including ground-penetrating radar (GPR), thermal imaging, terrestrial laser scanning (TLS), combined with visual inspection. GPR was used to assess wall thickness and detect potential hidden voids within the building, providing detailed information on material integrity and identifying structural anomalies. Thermography was applied to locate beams and areas affected by humidity, offering essential data for corrective interventions and structural strengthening. The combination of TLS and visual inspection enabled the creation of an accurate 3D BIM model. This method provides a detailed virtual representation of the geometry and current condition of the building, facilitating subsequent structural monitoring and allowing the inclusion of particularly useful data for future studies or restorations. This case study highlights the successful implementation of innovative technologies for the preservation and strengthening of architectural heritage. It serves as a model for future research and the practical application of advanced solutions in structural health monitoring.
