What would an example of the amount due adjusted for inflation look like (for Options A and B)?
Assuming: the increase in the Price for Work Done to Date in the assessment is £5,000; the Price Adjustment Factor (PAF) is 0.05 (i.e. 5% inflation since the base date)…
£5,000 x 0.05 = £250 (this is for the first bullet point in Clause X1.4)
The sum of £250, plus the total of the sums resulting from the same calculation in previous assessments (second bullet point in Clause X1.4), plus any correcting amount (third bullet point in Clause X1.4) is the amount for price adjustment included in the amount due.
