for completion. Material schedules show when the
material is needed on the job. They may also show
the sequence in which materials should be delivered.
Equipment schedules coordinate all the equipment to
be used on a project. They also show when it is to be
used and the amount of time each piece of equipment
is required to perform the work. Manpower schedules
coordinate the manpower requirements of a project
and show the number of personnel required for each
activity. In addition, the number of personnel of each
rating (Builder, Construction Electrician, Equipment
Operator, Steelworker, and Utilitiesman) required for
each activity for each period of time may be shown.
The time unit shown in a schedule should be some
convenient interval, such as a day, a week, or a month.
Network analysis is a method of planning and

interdependence in diagram form. This enables you
to undertake each problem separately. The diagram
form, known as a network diagram, is drawn so that
each job is represented by an activity on the diagram,
as shown in figure 9-1. The direction in which the
activities are linked indicates the dependencies of the
jobs on each other.
Progress control is the comparing of actual
progress with scheduled progress and the steps
necessary to correct deficiencies or to balance
activities to meet overall objectives.
LEARNING OBJECTIVE: Upon completing
this section, you should be able to give the
documentation requirements necessary in
planning a construction project.
There are two basic ground rules in analyzing a
project. First, planning and scheduling are separate
operations. Second, planning must always precede
scheduling. If you dont plan sequentially, you will
end up with steps out of sequence and may
substantially delay the project. Everyone concerned
should know precisely the following aspects of a
What it is;
Its start and finish points;
Its external factors, such as the schedule dates
and requirements of other trade groups;
