Table Q1 shows the cost of works and the program for the construction of a small building. The gross profit margin is 15 per cent of contract cost and retention is 5 percent. Progress payment is on monthly basis and measurement will be made at the end of each month and the contractor receives the payment one (1) month later. The retention money is paid six months after practical completion. To simplify the calculation you may assume that all costs must be met at the instant they are incurred. You may also assume that the monthly value and cost for each activity are equally distributed.
