This is an interesting question where I ad to check the contract - in this case NEC3, but I don't believe the situation is different under NEC4.
Neither off the top of my head or looking through the relevant clauses, could I find any clause which expressly allows let alone obliges the Project Manager to notify one of the compensation events for which the Contractor is obliged to notify.
