What evidence supports a delay notice?
Last reviewed July 5, 2026
You need solid proof for a delay notice. This includes the original program, updated schedules, correspondence with the super, and site diary entries. Document anything that shows the cause of the delay and its impact on the timeline.
Key points
- Original program and updated schedules
- Correspondence with the super
- Site diary entries and daily reports
When you raise a delay notice, back it up with clear evidence. Keep track of all communications and site activities. If weather or design changes cause delays, make sure that's in writing. The more detailed your records, the better your case.
