Materials & evidence

Keep appearance and performance separate

A visual impression answers only some questions.

Understand the information

An item may look similar to another while differing in ways that matter to the project. Record a visual observation for what it is and use the required qualified evaluation for performance or compliance questions. Avoid describing an attractive or tidy specimen as proof that a technical requirement has been satisfied.

Make the next conversation clearer

Link the visual record to the relevant item and context, then state what further information is needed. Photographs can support identification and discussion without replacing a test or engineering assessment. Keeping these purposes separate helps a report remain clear about what was observed and what the responsible reviewer has actually established.

A practical briefing checklist

  • Label visual observations accurately.
  • Link images to item identity.
  • Use appropriate performance evaluation.

Technical learning resources

Educational reading about records and communication. Actual investigation, inspection, design and environmental assessment require appropriately qualified professionals and the applicable project procedures.
