Interdisciplinarity for Architectural Heritage: an HBIM data modelling approach for the Church of San Tomè in Almenno (BG)

The paper outlines a potential methodological workflow for developing an informative apparatus related to the Church of San Tomè in Almenno San Bartolomeo, in the province of Bergamo. With its central, round layout and distinctive decorations, the church stands out for its originality while displaying the typical features of Romanesque churches. It is a highlight of the Almenno Romanesque Park. The digital acquisition outcome was first segmented and imported as separated point clouds into the BIM environment for its geometric and informative representation. The semantic structure of the model follows the characteristics peculiar to Romanesque decorative elements. It was designed with the proper information management workflow, including structural analyses and detecting existing cracks. The iconographic analysis enriched the historical informative apparatus, making the HBIM model a valuable tool for investigating and preserving an evolving historical heritage.
