How do I substantiate an extension of time (EOT) claim?
Last reviewed July 5, 2026
Gather all relevant documents like contracts, project schedules, and correspondence. Clearly outline the reasons for the EOT claim, linking them to specific contractual clauses. Provide evidence, such as delays caused by weather or site access issues, and ensure you meet the notification deadlines.
Key points
- Collect all supporting documents.
- Link delays to contract clauses.
- Document reasons clearly.
Make sure you've got your timelines and communication records sorted. If you had delays due to things outside your control, like bad weather or late deliveries, document everything. Don't forget to check the contract for deadlines on notifying about delays, or you might miss out on your claim.
