  16. 16. Example:The following information belong to a target cost contract:Target cost = L.E. 160 M.Cost at the start of target band = L.E. 155 M.Cost at the end of target band = L.E. 165 M.Target fee = L.E. 20 MCost saving share = 60/40, (60% by the client)Cost increase share = 70/30, (70% by the contractor)Required:Calculate the contractors fee for the following cases:I. If the cost of project equals L.E 163 M.II. If the cost of project equals L.E 177 M.III. If the cost of project equals L.E 184M.IV. If the cost of project equals L.E 140 M. 16
  17. 17. Solution: If the cost of project equals L.E 163 M. Contractor fee = 20M. If the cost of project equals L.E 177 M. Contractor loss= (177-160)*0.7= 11.9M. Contractor fee= 20-11.9=8.1M. If the cost of project equals L.E 184M. Contractor loss= (184-160)*0.7= 16.8M. Contractor fee= 20-16.8=3.2M. If the cost of project equals L.E 140 M. Contractor excess= (160-140)*0.4= 8M. Contractor fee= 20+8=28M. 17
