Exercise 32

The Virginia Department of Transportation is undertaking a construction project to widen a large section of interstate highway near Washington, DC. The project includes the construction of a number of new bridges, interchanges, and overpasses. The first step in the project is to appoint a project manager and develop a project team, whose members will be departmental employees and private consultants and operatives. The team for a project this size also requires a large support staff with a variety of technical skills. Once the team is selected and the staff is in place, the next task is to select a primary contractor to manage and oversee the construction. The following activities are standard for the planning and scheduling of this process:
Construct the CPM/PERT network for this project and determine the project schedule. Identify the critical path and determine the expected project duration time and variance. What is the probability that the team and contractor will be in place and the project started within 6 months within 1 year
