20. OpenBIM Concept
Native data
(Master)
Native data IFC BIM software
(Master) Read only
IFC
BIM software Read only
The ”Cloud”
IFC Basic assumptions:
Read only • Master data in applications (native proprietary
format)
• Applications publish a part of their data as IFC
• Only the application that has created and owns data
Native data can change it (No roundtrip)
(Master) DRUM - Distributed information • IFC model is a collection (combination) of discipline
specific models that coexist throughout the project

22. ”Cloud” functionality
• Transaction based communication
– Subscribing to published IFC datasets with incremental updates
• Any client can subscribe to any data published by another application,
current situation transferred initially and then changes only, as they are
published
– Workflow type of action transactions with (semi)automatic routing
• Eg MEP engineer needs penetrations through structures and requests
these from architect and/or structural engineer.
• Managing and publishing metadata of and from participating
models
• Creating, Managing and publishing relationships between objects
in the participating models

23. BIM process Example – Penetration Request
Mechanical designer and
structural designer can
see their local and all
foreign models
– MEP local + Structural IFC
– Structural local + MEP IFC
Penetration request
– MEP designer creates
request = reservation object
+ status information
– Structural designer approves
request and creates
penetration with reservation
object
– MEP designer adds a
pipeline
– Modifies the penetration
request
– Structural designer
recognizes the changed
request, adjusts the
penetration to suit and
approves the request
