What evidence supports a variation claim?
Last reviewed July 5, 2026
You need clear documentation for a variation claim. This includes the original contract, change orders, correspondence, site instructions, and photos showing the changes. Make sure to log all discussions and decisions related to the variation.
Key points
- Original contract documents
- Change orders and site instructions
- Correspondence and photos as evidence
Variations can happen for many reasons, design changes, site conditions, or client requests. Keep detailed records of everything leading up to the claim. It helps if you've got a well-organised system for tracking these changes, as it makes the process smoother when it's time to claim.
