This document discusses digitalization in construction through BIM and 3D modeling tools. It summarizes several software tools that allow syncing between BIM authoring tools like ARCHICAD and game engines like Unity and Unreal for visualization. It also discusses using IFC files to manage and parse BIM data at the backend and render it in desktop clients. The technologies used in one demo are described as Unreal Engine for rendering, .NET Core as the backend, and IFC as the BIM data standard format. Pros and cons of the IFC format are also listed.

10. How DemoWorks
BIM data in IFC files are managed and parsed at Backend.
Then converted to 3D data and fetched by Desktop client.
Finally Rendered to the User.
Technologies Stack for the Demo:
• Unreal Engine – Powerful Render on Desktop. C++
native code speed.
• .NETCore – Cross-platform Backend. Fast. Corporate
power from Microsoft.
• IFC – BIM standard data format. Contains layers and
Meta Filters. Has standards.
