The PM should make their own assessment in accordance with 64.1 which is where:
• Contractor not submitted a quote on time
• Do not agree with the Contractor’s quotation
• CE affects remaining works and no programme has been submitted with a quote
• Latest programme rejected or not issued for acceptance
Once implemented it is full and final so important the PM makes sure they make a correct assessment in accordance with the contract. Good practice to informally share a draft with the Contractor so they have the last chance to try to convince the PM that they are wrong – which they can consider before implementing into the system.
Making a PM Assessment
The PM can make their own assessment of a quotation if the Contractor has not submitted one or they do not agree with the quotation submitted (and the Contractor has not been asked to resubmit a new one). They will have to identify which CE they are assessing, what their assessment is in terms of Price and programme effect and then describe in detail how they got to their assessment. There is the option to attach further substantiation before implementing.
