solution

The Bender Construction Co. is involved in constructing municipal buildings and other structures that are used primarily by city and state municipalities. This requires developing legal documents, drafting feasibility studies, obtaining bond ratings, and so forth. Recently, Bender was given a request to submit a proposal for the construction of a municipal building. The first step is to develop legal documents and to perform all steps necessary before the construction contract is signed. This requires more than 20 separate activities that must be completed. These activities, their immediate predecessors, and time requirements are given in Table 11.10 on the next page. As you can see, optimistic, most likely, and pessimistic (b) time estimates have been given for all of the activities described in the table. Using the data, determine the total project completion time for this preliminary step, the critical path, and slack time for all activities involved.
