NEC4 Option B CE Reduces total quantity

The Client has issued a PMI with revised drawings which reduces the quantities in the BoQ and in some cases completely omits BoQ items. No work has been undertaken on these BoQ items.

Under Clause 63.1, where the quantity has reduced, is the forecast Defined Cost based upon the difference in the reduced quantity (i.e. 100m - 70m = 30m) OR is it the difference between the forecast Defined Cost of the quantity in the original BoQ item (100m) and the forecast Defined Cost of the quantity in the revised BoQ item (70m) and disregarding the original BoQ rate.

Where the BoQ item has been omitted completely, it does not seem right to use the forecast Defined Cost as the process if the works are not required at all unless the latter option in the above scenario applied. Otherwise, the Contractor would be pay for the privilege of this omission.
