Abstract. The digitalization of architectural heritage requires the integration of interoperable tools for the documentation, modeling, and sharing of cultural assets. This study proposes a methodology applied to the case of the Monastery of San Nicolò del Lido in Venice, aimed at HBIM modeling, collaborative management through open-source platforms, and immersive visualization. Based on an integrated photogrammetric and laser scanner survey, a BIM model was created in Revit, exported in IFC format, and uploaded to BIMData, an open-source Common Data Environment platform. The infrastructure was enhanced through the integration of the ARKBIM plug-in within a Vue.js environment, enabling semantic navigation of the model. In parallel, realistic visualization was explored using Mark Kellogg’s 3D Gaussian Splatting Viewer, integrated within the same framework, to offer a photorealistic and immersive experience of the current state of conservation of the architectural artifact. The result is a scalable, accessible, and replicable workflow that combines interoperability, information management, and rendering for the enhancement of cultural heritage. The methodology highlights the potential of 3D Gaussian Splatting as an effective complement to BIM models, expanding the modes of engagement and communication for a diverse audience.
