4. Project managers have many resources that are not directly under their control, such as the designer and the owner. Provide at least 5 bulleted points describing in detail how project managers can manage (influence) resources outside of their control or above them in the contractual hierarchy. 5. For the following simple seven-activity project, develop a precedence network, calculate all relevant characteristics of each activity (ES, EF, LS, LF, TF), and calculate the project duration. Then draw a time-scaled network and under it a labor resource histogram for the ES. Do the same for the LS. In both cases, use the maximum allowable number of workers. Make adjustments to the noncritical activities, within the constraints of the ES and LF and the maximum and minimum workers allowed to provide what you feel is the best labor distribution. Please use Table B (Table B.pdf) Lastly, Explain in detail what do you feel is the biggest problem with the ES and LS configurations, and how has…
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.
