Ponderosa Construction has budgeted $350,000 to build a new clubhouse at the Sun Lakes Golf Course outside Tampa, Florida. Ponderosa uses a mixture of union and nonunion personnel. Grading of the land, electrical, and plumbing work is subcontracted out to union shops. The actual construction of the project, though supervised by union carpenters, is performed mainly by nonunion laborers to conserve costs. Project planning has produced the following chart.

a. Draw a PERT/CPM network for this problem.

 b. Prepare a chart showing the earliest/latest start and finish times and the slack for each activity. What is the expected completion time for the project?
