BIM Data Flow
How building information modelling (BIM) data flows between designers, contractors and the owner: coordination, clash detection, quantities and handover.
Drawing diagram…
What this diagram shows
- Architecture, structure and MEP models are federated in a common data environment
- Clash detection finds conflicts before construction
- As-built data is handed over for facility management
Prompt used
Data flow for BIM: architects, structural engineers and MEP consultants publish models (IFC) to a common data environment, a federated model is built for coordination, clash detection finds conflicts (duct through beam) that go back to designers as issues. Quantity take-off feeds cost estimates, 4D scheduling links model elements to the construction schedule, site progress updates the model, and the final as-built model with asset data (COBie) is handed over to facility management.
