The contract talks about Project Manager assumptions within a quote that can be revisited (as a new CE). There is no where in the contract that says a Contractor assumption or qualification can be revisited.
Therefore I always recommend to Contractors to get PM's to agree assumptions suggested by the Contractor PRIOR to the quotation being issued for acceptance, and otherwise to price the risk instead and accept the quote will be higher.
