IENG 481: Project Engineering Question 1.1 Complete the network given in Figure 1. Activities A and B are the starting activities. The network should show slacks at the start and at the finish. The given durations are in weeks. (30 marks) (30 Question 1.2 Give critical length and identify all Critical Paths in the completed network in Figure 1. (4 marks). Critical path(s): A CD EGIL ACOE GKL VO Critical length A, CD, ,G,K, ID Question 1.3 Identify all Free Slacks and Total Slacks in the space provided below. (4 marks). Free slacks: + Total slacks: E and it 2 free slacks? Question 1.3 IF D, E, F, G, H, I, J, and K activities are treated as Hammock activity, how would the network be rewritten now? Draw the network below showing the right durations, ES, LS, EF, LF, slacks and identify the critical path. (5 marks).

Show in the network (in Figure 1) as to how these changes in the duration will change the total network in terms of slacks and in terms of critical path and critical length. You have to complete all forward and backward passes and slacks in the network and write answers to the following below. (5 marks). Critical path(s):_Ahere is critical path Critical length: Question 2: Under which circumstance, do you have to use an apportion method for cost estimation?
