Does the issue of a revised Programme by the Contractor constitute an Early Warning under the contract if it shows a forecast delay to the Completion?

In simple terms I would say no.

In a similar way if you include a compensation event on a programme, that does not be default mean you have notified. Clause 13.7 states that any notification that this contract requires has to be communicated separately from any other form of communication. Clause 16.1 uses the word “notifying” when it comes to early warnings.

In any case, i think I would rather get the message across twice than not at all.
