The shared platform for all project information. The single shared platform where all project information is stored, managed, and distributed. Instead of files flying around by email, everything lives in the CDE - models, drawings, documents, correspondence.
A CDE divides project information into four key zones:
| Zone | Who has access | What it contains |
|---|---|---|
| WIP (Work in Progress) | Creator only | Unfinished work not yet ready to share |
| Shared | Project team | Information approved for coordination |
| Published | Client & stakeholders | Formally issued deliverables |
| Archive | All | Superseded versions, kept for record |
The CDE is the backbone of ISO 19650-compliant BIM workflows.
