[7 marks]Write down short note on various stages included in a typical construction project cycle.
[3 marks]Draw AOA network diagram for the following. (Do not use redundant dummy). Activity C & Dcannot begin until both activity A & Bare completed.
[4 marks]Consider the following network diagram of a construction project and answer the following questions. (The time shown are in weeks). Identify the critical path. How long it will take to complete the project? Can activity Dbe delayed without delaying entire project? If so, how many weeks? Can activity Cbe delayed without delaying entire project? If so, how many weeks? What is the schedule of activity E?
[7 marks]Draw a network (AOA) from the following activities and find critical path and duration of project.1
[7 marks]Write down rules for drawing CPM AON network diagram.
[3 marks]In general, what is the effect of accelerating an activity on the direct costs of a project. Why?
[4 marks]Draw AON diagram for the activities listed below. Also find critical path and total float. Activity IPA Duration (Weeks) A - B A C A 1 D A E B F B G B H E, F I D, F, G 1 J C, G 9 K H L H, I, J M K, L
[7 marks]Discuss various rules for providing dummy in a network diagram. What are the redundant dummies?
[3 marks]State your answer with justification. Your critical path is 128 days long. The next-longest path is 122 days long. a. If you extend the longest path by 5 days, the entire project duration will increase by 5 days. True or false? b. If you reduce the longest path by 5 days, the entire project duration will decrease by 5 days. True or false? c. If you reduce the longest path by 10 days, the entire project duration will decrease by 10 days. True or false?
[4 marks]Asubcontractor must do the following: a. Framing (5 days) b. Drywall installation (4 days) c. Drywall finish and paint (3 days) Assuming he wants to make sure each activity finishes as least 1 day after its predecessor has finished, draw these three activities in a precedence diagram and calculate how much time the subcontractor would need to finish all three activities.
Explain the term ‘Earliest Expected Time’. Formulate an expression for determining the same.2
[3 marks]What does the term accelerating a project mean? Why would a project manager (or a contractor) accelerate a project?
[4 marks]For the project data given below, calculate the cash flow requirement for first 10 weeks if the project is scheduled as per early start of activities (ES Schedule). Activity IPA Duration Total Cost (Weeks) (Rs) A - 4 6000 B - 5 15000 C A 3 5000 D A 2 10000 E B, C 6 9500 F A 8 7000 G D, E 3 7000 H B, C 2 11000
[7 marks]The expected completion time for a project is 32 months with a variance of 7.6 months. What is the probability that project will not be completed in 30 months.
[3 marks]What do you understand by Cash flow diagram? How does it influence a construction project?
[4 marks]For the project data given below, calculate the cash flow requirement for first 12 weeks if the project is scheduled as per early start of activities (LS Schedule). Activity IPA Duration Total Cost (Weeks) (Rs) A - 4 6000 B - 5 15000 C A 3 5000 D A 2 10000 E B, C 6 9500 F A 8 7000 G D, E 3 7000 H B, C 2 11000
Management must pay attention not only to critical activities, but also to near-critical activities. Explain this statement from a practical point of view.
[3 marks]Explain central limit theorem and how it is used in PERT problems.
[4 marks]Figure shows the network for a construction project, with the three time estimates of each activity marked. Determine, 1. Probability of completion of the project in 45 days. 2. The duration that will provide 95% probability of its completion in time.3
[7 marks]What are the Advantages and Limitations of LOB method?
[3 marks]The earned value (EV) analysis involves comparing what happened with what should have happened. Explain this statement regarding both the budget and the schedule.
[4 marks]Calculate Normal Cost, Least Cost & Crash Duration for the following project. Calculate the cost associated with each duration. Indirect cost is $100 per day. Activit Duration (Days) Cost ($) IPA y Normal Crash Normal Crash A -- 7 5 500 640 B A 6 5 550 630 C A 8 5 800 935 D B 10 7 1200 1440 E B,C 6 4 600 700 F C 4 3 500 590 G D,F 4 2 700 1000 H E,F 7 4 650 950 I G,H 2 2 300 3004
