The Contractor has indicated that the implications of a CE instructed under 61.1 will have a time effect on the Planned Completion. They would like an extension of time in order to try to mitigate this delay, through a collaborative risk meeting etc. to which the PM granted. However during this period a revised programme for acceptance was issued that showed that the Planned Completion Date was brought forward.
My question is once the time for the CE has been agreed, which programme should be used to show the effect of the CE, the revised programme or the accepted programme at the time the CE was issued.
