A Typical Building Project Bar Chart Schedule
Figure 2 shows a typical building project bar chart
which relates the master schedule activities to the phases outlined in Figure
1. You will see that the acceptance of a tender and award of the major contract
is taken as an arbitrary zero on the time base. This is because it is a clearly
defined point in time and its significance in the life of a project is commonly
understood. The time durations shown were derived from a fairly large sample of
building projects costing from under $1 million to several million, and are considered
to be representative.

From the data, you will be interested to note that most projects have been
in existence for as long as it will take to construct them. The implication is
that the start of construction must be preceded by adequate time for conceptual
and functional planning as well as the preparation of the necessary design and
administrative documents and procedures.
