General Aviation Hangar Restoration
Read the following case to answer the following questions.
1. Describe the nature of the project, and its key objectives.
2. Define “Dummy Activities” and describe their role in this project.
3. Describe the key problem(s) in this project and the strategies used to address these problems. Introduction
This case example, although for a very small project, illustrates some interesting features of planning using critical path analysis. although there are only 17 activities, the precedence logic is a little complex to draw clearly owing to the number of crossed links, and we show how this difficulty is easily overcome by inserting dummy activities at three of the crossover points.
Our case example demonstrates the application of pert (program evaluation and review technique), in which the estimated duration for each activity can be subjected to a probabilistic study in an attempt to forecast the most likely completion time for the entire project.
Finally, this case will demonstrate how a project manager need not accept the results of time analysis without question, but can plan to apply extra effort to expedite critical activities (usually for additional cost) to bring the planned project completion date forward.

Project Background
CEN-CONSTRUCT is a medium-sized business located in Sydney, Australia that is owned and operated by a family. It is principally a consulting company that specializes in aviation civil engineering, having worked on runway construction and paving projects as well as several other airport airside projects, most of which have been for smaller general airports. Having decided to extend its range of operations, the company recognized a local need for a contractor that could carry out aircraft hangar renovation. In consequence, the company has now achieved a good level of expertise in the
