never backward. Also remember that activities that
show no free float are tied by dependency to other
activities. If one moves the others must move. Such is
the case of activities 4000 and 4005.
Some minor adjustments on crew sizes and
durations may be required to ensure full use of
assigned crew. Once all the activities are scheduled,
you can input the noncritical resources and delayed
start dates (using lags) and create a new barchart. You
can create this new barchart with the computer or
manually.
LEVEL II BARCHART
You make a level II barchart from the information
gained from the level III. Figure 2-19 is a level III
barchart with construction activities sorted by activity
number. This sorting allows for an easy transfer of
information to the level II. Vertical lines on the level
III separate the weeks and horizontal lines separate
the master activities. The man-day estimate has been
taken off the CAS sheets and penciled-in to the left of
each activity number. The man-days have also been
written over each line representing the activity
duration. Where an activity was split between 2 weeks
the man-days were prorated between the 2 weeks.
Master activity 10 has a total man-day estimate of 19
(the sum of the construction activity estimates). You
can now transfer the information to a level II barchart.
Figure 2-20 is a level II barchart. The master
activities are listed in a column on the left and the
weeks of the entire deployment across the top. The
dates used are always the Monday of that week. Next
to each master activity is the man-day estimate for
that master activity. The next column is the weighted
percent, which is the master activity man-day
estimate divided by the total project man-day estimate
