HBIM IN A SEMANTIC 3D GIS DATABASE

TLDR

The study aims to integrate an HBIM model into a structured spatial database and visualize it within a GIS project as part of the European ResCult initiative. The authors built a Revit-based HBIM of Santa Maria dei Miracoli, linked architectural elements via shared parameters and system families, and extended the resilience database to map IFC data to CityGML using FME. The integration achieves LOD4 detail but reveals semantic and software interoperability challenges. Abstract.

Abstract

Abstract. This work describes the different attempts and the consequent results derived from the integration of an HBIM model into an already structured spatial database (DB) and its 3D visualisation in a GIS project.This study is connected to the European ResCult (Increasing Resilience of Cultural Heritage) project where a DB for multiscale analyses was defined. To test the methodology proposed, the case study of Santa Maria dei Miracoli church in Venice was chosen since it represents a complex architectural heritage piece in a risk zone, it has been subject to a vast restoration intervention in the recent past but a digital documentation and model concerning it was missing.The 3D model of the church was structured in Revit as a HBIM, with the association of different kind of information and data related to the architectural elements by means of ‘shared parameters’ and ‘system families’. This procedure allows to reach an even higher Level of Detail (LOD4), but lead to some issues related to the semantic and software interoperability. To solve these problems the existing DB for the resilience of cultural heritage was extended adding a new entity representing the architectural elements designed in the BIM project.The aim of the test is to understand how the data and attributes inserted in the HBIM are converted and handled when dealing with a GIS DB, stepping from the IFC to the CityGML standard, through the FME software.
