- Remember to sign and date your site notes; this needs to be reflective of the actual inspection date.
- Photos need to be provided individually in their original jpeg format (not embedded into a pdf or word document). This allows the date taken to be checked against the nominated inspection date.
- Site notes need to be scanned and not photographed.
The above table will be used as part of our auditing process; missing evidence will be clearly marked and could have an impact on the auditors ability to complete a satisfactory audit.
Please review your Inspection and evidence submission processes to ensure that you are able to comply with the Government Requirements.
