We are working on an ECC Option C which is drawn off from a framework. X1 is chosen but no indices was placed into CD1. There is only a reference to the frame work which does not mention any indices or inflation calculation processes. the framework only references the auditing protocol which allows for any under or over recovery to be rectified.
The PM is reluctant to agree to the Contractors proposals of indices, as he believes the auditing protocol in the framework is how it should be dealt with and that the Contractor had agreed to this when they signed the contract.
So the question is does the PM have the right to do this?
