Under clause 63.3 (NEC3 ECC) or clause 63.5 (NEC4 ECC) if, due to the compensation event, there is no effect on planned Completion compared with that in the Accepted Programme, then there is no change to the contractual Completion Date. I think you are in agreement on this.
Under clause 63.1 (both NEC3 & 4 ECC), you are entitled to the change in Defined Costs and resulting Fee due the compensation event. So are you entitled to the additional mobilisation costs of the resources which were not previously 'mobilised'.
I put 'mobilised' in inverted commas because to me that means the costs of getting them into the Working Areas. If that is the same as your meaning, then for both the existing and newly mobilised resource, you would also be entitled to the extra Defined Costs of doing the additional works e.g. existing resource will now be on Site one week longer so that it is an extra cost along with the additional resource. Further, there might well be an additional cost in de-mobilising the additional resource
