DIGITAL TWIN 3D PLATFORM FOR COLLABORATIVE REPRESENTATION AND EDITING OF IFC DOCUMENTS APPLIED TO THE BIM METHODOLOGY

Abstract. Currently , the Architecture, Engineering, Construction (AEC) sector lacks tools for digitization, being forced to resort to proprietary software and closed file formats with complex and highly expensive licensing models. Thus, new opportunities arise for the creation of tools, resources and knowledge that promote the renewal and impetus of the entire sector. Most of the sector’s R&D activities are not only directed to the development of digital tools, but also to develop and provide the methodological bases of standardization, organization, and management of information necessary for the implementation of the BIM and Digital Twin methodology in Portugal, applied to the construction and asset management of buildings and infrastructures. In the present work, the described solution is a cross-platform web application that has all base requirements of a standard BIM platform, plus georeferencing of IFC documents using orthophoto maps and free access to base cartography available globally. All components of the solution were developed using open source technologies and universal free access. The contributions of this work will also serve to improve the set of tools and solutions available to the community. The developed platform will be available openly to all companies that want to engage in the BIM community and ought to actively participate in and foster the development, improvement, and promotion of this platform within the AEC sector.
