Construction variation management guide
A practical guide to recording construction variations clearly, from site instruction through to office review and billing preparation.
Start with the instruction
A useful variation record should explain what changed, who requested it and why it was outside the expected scope. Capture the detail as close to the site instruction as possible.
- Record the project, client and location context.
- Capture who gave the instruction and their role where known.
- Add a clear description of the extra work, not just a short label.
Structure the value early
A variation becomes easier to review when labour, materials, plant and other items are entered as structured lines instead of being buried in messages or paper notes.
- Use approved rate-card or SOR lines where possible.
- Keep quantities, units and rates separate.
- Flag custom lines for office review before billing.
Keep evidence with the record
Photos, notes, signatures and timestamps are strongest when they stay attached to the same record instead of being spread across WhatsApp, email and folders.
- Add photos before and after the work where useful.
- Include signature or remote approval evidence.
- Generate a consistent PDF evidence sheet for review.
