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
