If using BQ, we can use the below two bullets to forecast the total of the Prices:
The total of the Prices is the total of:
The quantity of work which the Contractor has completed for each item in the Bill of Quantities multiplied by the rate and
A proportion of each lump sum which is the proportion of the work covered by the item which the Contractor has completed (see Clause 11.2(33)).
However, under Option C (Activity Schedule), how can we apply these principles to forecast the total of the Prices?
