OpenBIM Concept

Basic assumptions:

• 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

can change it (No roundtrip)

• IFC model is a collection (combination) of discipline

specific models that coexist throughout the project

”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

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
