The Ontario Ministry of Transportation is undertaking a construction project to widen a large section of high-way near Ottawa, which includes the construction of a number of new bridges, interchanges, and overpasses. The first step in the project is the appointment of a project manager and the development of a project team, some of which will be departmental employees and others will be private consultants and operatives. The team for a project this size also requires a large support staff with varying technical skills. Once the team is selected and the staff is in place, the first task is to select a primary contractor to manage and oversee the actual construction. The following table shows the standard activities 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. Determine the probability that the team and contractor will be in place and the project started within six months and within one year.
