Scope changes during design are inevitable — but unmanaged changes cause cost escalation, delays, and rework.
1. Common Sources of Design Change
- Client-driven modifications.
- Coordination conflicts (e.g., MEP vs. Structure).
- Regulatory compliance updates.
- Design development refinements.
- Errors or omissions found during peer review.
2. Change Control Workflow
3. Tools for Scope Control
- Design Change Register (DCR)
- Request for Information (RFI) logs
- Change Order Forms with justification
- Version History Reports
“Every design change must be visible, justified, and approved — not just assumed.”
