Say the Original BOQ for Pile Test 500 ea @ £100, then qty later revised /reduce (due to redesign by owner) to 300 ea, with 100 ea already done @ £50 (actual cost each) and 200 not yet done. What is the correct approach to reduce the Target Price using Option D?
The guidance note says that you consider the actual define cost for works already done plus forecast the defined cost. Is the result of this becomes the new price? or do u have to deduct the result from the original target cost for the item, to get the revised target cost?
