How to correct investigation notes without losing the record on construction sites
For subcontractors and safety managers: when an investigation note turns out to be wrong, correct it openly. A practical approach to amendments that keeps the original visible and the reasoning clear.

Mistakes are normal
For your subcontractor crews, use this guidance with the current work phase, trade responsibilities and approved procedures in view. Keep your safety manager involved in record reviews and follow-up. This guidance supports record keeping and coordination, not technical authorization to carry out the work.
Early investigation notes are written with incomplete information. A time is wrong, a witness is misnamed, a piece of equipment is misidentified. Correcting these is part of good practice. Hiding them is not.
Amend, do not overwrite
The safest approach is to keep the original entry and add a correction that explains what changed and why. That way anyone reviewing later can see how understanding developed.
- State what was originally recorded
- State the correction and its source
- Note who made the change and when
Revisit linked findings
A corrected fact may affect a finding or an action. After each correction, check whether anything that relied on the original note needs to be reviewed.
The takeaway
Treat corrections as part of the record. Visible amendments build more confidence than a clean history that cannot be checked.
