The Contractor submitted an EWN stating that they had been requested (not instructed) not to issue a design pending the outcome of a meeting.
The PM responded to the EWN with a comment to hold on submission of the design report until instructed.
The PM gave the formal instruction to proceed a month later without notifying that it was a compensation event therefore negating the time bar on the contractor becoming aware of the event.
The design report was submitted a week after the instruction.
The contractor has subsequently submitted a notification of CE stating the original reponse date of the EWN as the point at which the delay began.
I would argue that, although the contractor should have been notified at the time of the EWN, the contractor should have been aware of the event at that point and submitted a notification within 8 weeks.
