Design decisions and change control that keep BIM synchronized
Link questions, responses, approvals and model consequences so teams can understand what changed, who authorized it and what must be reissued.

Minimum workflow
Five controls to keep.
- 01
Frame the question
Describe the location, affected information, constraint and date by which a decision is needed. Attach only the evidence needed to decide.
- 02
Name the authority
Separate the person coordinating the query from the party authorized to direct or approve the outcome.
- 03
Assess consequence
Identify affected disciplines, deliverables, programme, cost, procurement, approvals and previous decisions.
- 04
Translate into work
Create owned update actions for every affected model, drawing, schedule and downstream package.
- 05
Verify the issued state
Record where the approved outcome appears and confirm superseded information is withdrawn or clearly marked.
Supporting records
Artifacts that make the process visible.
- RFI and technical-query register
- Decision log
- Change and impact register
- Affected-deliverables and reissue record
Useful measures
Measure flow and acceptance—not activity.
- Open queries beyond required-by date
- Decisions awaiting incorporation
- Reissues caused by missed impact assessment
- Approved changes verified in deliverables
Early warnings
Failure patterns to challenge.
- 01
Email treated as the only decision record
- 02
Response date confused with approval date
- 03
One discipline updates while dependants remain stale
- 04
Superseded drawings remain available for use
