Adam Gold is making plans for spring break in England. In applying techniques he learned in his quantitative methods class, he has identified the activities that are necessary to prepare for his trip. Table 1 lists the activities and the immediate predecessors. Draw the network for this project.

The Reigner Corporation is constructing a 10-story office building at their new business location. A list of activates and their optimistic, most likely, and pessimistic completion times are given in Table 2 for this construction project.

a. Develop a project network for the problem.

b. Determine the expected duration a variance for each activity.

c. Determine the ES, EF, LS, LF, and slack time for each activity. Also, determine the total project completion time and critical path(s).

d. What is the probability that this job will finish in 38 days or less?

The Dream Team Corporation is trying to figure out the value of work that has been completed on their space-building project since its inception 8 weeks ago. They have approached you to help them with the evaluation. They wanted to know the value of work completed to date, the amount of any cost overruns or underruns for the project, and the extent to which the project is ahead of or behind schedule buy developing a table like Table 3.
