Colonial State College is considering building a new multipurpose athletic complex on campus. The complex would provide a new gymnasium for intercollegiate basketball games, expanded office space, classrooms and intramural facilities. The following activities would have to be undertaken before construction can begin:

A. Construct the Project Network using AOA (Activity-on-arrow) method. Using normal times and costs, compute the project duration using forward pass and backward pass. Plot also the critical path and identify the critical activities. What is the projects normal cost?

B. Specify what activities you will crash in order to shorten the project completion time by 4 weeks. Show your solutions. What is the resulting total project cost for a reduction of 4 weeks?
