NEC3 ECC: Assessment periods after termination notified

Can the Contractor submit an assessment in accordance with the assessment schedule (as included with the contract) after termination or does the Project Manager delay the assessment until 13 weeks from termination in accordance with clause 90.4?

Once the termination notice has been served the procedure in the termination provisions will apply in terms of payment as the contract has ended. That is, of course, assuming that the termination has been carried out effectively.
