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.
NETWORK ANALYSIS
A network analysis is a method of planning and
controlling projects by recording their inter-
dependence in diagram form. This enables each funda-
mental 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.
