How long should construction daily reports be kept?
Keep construction daily reports for a minimum of seven years after project completion. This covers retention requirements under most state WHS regulations, workers' compensation legislation, and standard contractual limitation periods in Australia. For projects with significant claims exposure or long defects liability periods, retain records for longer.
What drives the seven-year number?
Three obligations overlap at seven years. WHS regulations in most Australian states require safety and incident records to be kept for five to seven years depending on the type of record and the jurisdiction. Workers' compensation claims can arise years after an injury occurred. And the standard limitation period for contract claims in Australia is six years from the date the cause of action arose. Disputes from a project can surface years after handover.
Seven years from practical completion clears all three. It's the practical minimum, not the conservative maximum.
This is general guidance. Specific obligations vary by state, contract type, and project circumstances. Consult your legal or WHS advisor for requirements applicable to your situation.
WHS and safety records specifically
Under the Work Health and Safety Regulations, notifiable incident records must be kept for at least five years from the date of notification. Safe Work Australia recommends retaining all WHS records, not just notifiable incidents, for at least five years, with many advisors recommending seven to match the broader contractual position.
Workers' compensation investigators and coronial inquiries will ask for incident records. The site diary for that day can be the difference between proving what happened and being unable to account for it.
What about defects liability periods?
Defects liability periods in Australian construction contracts typically run 12 months to 2 years after practical completion. If a defect surfaces during that period and a dispute follows, site diary records from during construction may become relevant, particularly if the dispute concerns workmanship, site conditions, or whether a defect was identified and reported at the time.
The practical retention period for a project with a standard 12-month defects liability period is at least seven years from practical completion. For complex projects with longer defects periods or significant claims exposure, eight to ten years is reasonable.
Are digital records treated the same as paper?
Yes. The obligation is to retain the information, not the medium. Cloud-stored PDF reports generated from a digital diary satisfy retention requirements provided they remain accessible and unaltered for the required period.
One practical point: ensure your storage solution doesn't auto-delete files after a set period. Some cloud services apply retention limits by default. If your diary lives in an app with cloud storage, check the deletion and retention policy before relying on it as your only copy.
