break down the project into construction activities. This is normally done at the battalion level. From the construction activities, you will develop a logic network that will link the activities together into a sequence of events from the beginning to the end and will show the dependencies between the activities. Table 1-5 shows an activity block that represents a single construction activity.. This is the building block on which the whole project will be planned and controlled. The connection of these blocks and their interdependence on each other makes up a network diagram. The sum of these network diagrams is called a network analysis.
A network analysis is a method of planning and controlling projects by recording their interdependence in diagram form. This enables each fundamental problem involved to be undertaken separately. The network diagram form is drawn in such a way that each job is represented by an activity on the diagram, as shown in figure 1-9. This network diagram is based on the installation of the generators shown in figure 1-10.
