How to Organise Design-Supervision Records

The evidential basis

• —A visit plan linked to critical construction stages.
• —A record of the actual observation, including the area, date and current design revision.
• —A comment stating the required action, owner and deadline clearly.
• —Evidence of rectification or an approved design decision.

How to control departures

1. Register the matter and prevent the deviation from developing without control.
2. Review the original design decision and its impact on interfacing disciplines.
3. Obtain a decision from the authorised designer.
4. Issue the decision to the relevant parties and update related drawings or records.
5. Verify implementation and close the matter while preserving the full history.

Typical weaknesses

• —Comments remain only in a site log or correspondence.
• —A verbal agreement is never converted into a controlled document.
• —A revised decision is not communicated to every affected party.
• —Close-out is recorded without verifying the actual condition again.

The result of a controlled system

The Design Supervision package creates one workflow for visits, comments, departures, design decisions and supporting evidence. This protects the engineering intent and preserves a defensible history of decisions.
