Under option E a Contractor can only claim the costs that they are incurring. If you add work or take work away they should do so as efficiently as possible knowing that disallowed costs could be incurred if they incur a cost that could have been avoided.
This is the very nature of option E. The Contractor has no certainty of the amount of work they will be instructed to do. All they cam claim is their fixed fee for any work they do.
