The following table represents the logic sequence of U, V, W, X, Y & Z operations in a project of constructing and finishing 100 identical houses. It shows the man-hours/house and the optimum gang size required for each operation. A minimum 3 days buffer time exists between the finish of each operation and the start of its successor/s. The desired target is 4 houses/ week. The construction company typically works 8hrs/day 5days/week.

Calculate the commencement and completion times of each operation 2. Summarize your final result in BOTH a table and a diagram 3. Where should be the different gangs working after 70 days. Give your calculations of starts, finishes and durations of activities approximated to the nearest half day. Take the actual used number of gangs as the calculated required number of gangs rounded up to the next full gang.
