How is the ‘amount due’ adjusted for inflation for Options A and B?
Each amount due includes an amount for price adjustment which is the sum of:
The change in the Price for Work Done to Date since the last assessment of the amount due multiplied by the Price Adjustment Factor for the date of the current assessment
The amount for price adjustment included in the previous amount due and
Correcting amounts, not included elsewhere, which arise from changes to indicies used for assessing previous amount for price adjustment (see Clause X1.4).
