a big western city is requesting federal funding for a park-and-ride project. One of the requirements in the request application is a network plan for the design phase of the project. Yousif Walker, the chief engineer, wants you to develop a project network plan to meet this requirement. He has gathered the activity time estimates and their dependencies shown here. Draw your project network by AOA method with T box, computing the activity early, late, and slack times. Mark the critical path.

3. For the following seven-activity project, develop a precedence network, calculate all relevant characteristics of each activity (ES, EF, LS, LF, TF), and the project duration. Then go through a repetitive process to expedite the project on a least-cost basis until the project is crashed. The solution should include the precedence diagram and calculations for each activity, and then the cyclical calculation to shorten the project activity by activity in a least-cost manner. What is the total cost of the crashed project? Why is this less than the sum of the crashed costs for the seven activities? Please use Table A (Table A-2.pdf Please provide a detailed answer to this question.
