The Contractor has left the direct fee percentage entry blank. You speak to the Contractor about this and you are told that, it thought Contract Data part two had been completed properly, but nevertheless it should be 11% and the Contractor now wants to include this in Contract Data part two. You are told, verbally, that 'in a spirit of mutual trust and co-operation' you should agree. 

What does the contract state about such a scenario? Is the Project Manager able to change Contract Data? How might this be resolved and how should this be recorded?
