man-day estimate was 29. When 29 is divided by 434
the answer is 0.07 weighted percent.
Master Activity Percent Complete (WIP)
Obviously, for master activities not started the
WIP is zero percent and for completed master
activities the WIP is 100 percent. For master activities
that are partially complete, the crew leader must look
at the status of the individual construction activities.
Table 2-2 is expanded from figure 2-25 for master
activity 30, foundation/slab.
In evaluating the progress on master activity 30
you can see that you have completed the prefab of the
forms and the RST. These construction activities
represent 17 and 20 percent of the master activity. For
the set forms/RST activity you obtained the 50 percent
complete by actual measurement. Do not use
man-days expended, for they have nothing to do
with WIP. In this case you measured and determined
that one-half of the forms and RST have already been
set. Set forms/RST represents 40 percent of the master
activity, since you are half done you get credit for 20
percent. Add the 20 percent plus the previous 17
percent and 20 percent for a total of 57 percent
completion for master activity 30.
Project Percent Complete
Project percent complete represents that por-
tion of the work completed on the master activity
that contributes to the overall project comple-
tion. You get the project percent complete by
multiplying the weighted percent by the master
activity percent complete (WIP) for each activity.
Look at figure 2-25 master activity 20, underslab
utilities. The project percent complete was determined
by multiplying the weighted percent of 0.07 times the
percent WIP of 80 to get a project percent complete of
5.6 (0.07 x 80 = 5.6).
Actual Percent Complete
Actual percent complete for the project is the total
of the project 90 complete column. For the example in
figure 2-25 the actual percent complete for this project
is 14.2 percent. You will need to record the scheduled
percent complete at the bottom of the SITREP feeder.
You need to compare the actual progress to the
scheduled progress. The scheduled percent complete
comes from either the Deployment Execution Plan
(within the first 45 days of the deployment) or the
Revised Deployment Execution Plan (after the 45-day
review). The allowable percent deviation between
actual WIP and scheduled WIP is shown in table 2-3.
If the actual WIP is less than the scheduled WIP
by more than the percentage shown in table 2-3, the
battalion must advise 2ndNCB/3rdNCB by message.
This message must contain a plan detailing how to get
the project back on track. It must also request approval
for any required changes to the battalion level I or the
project level II in the revised deployment execution
plan.
Man-days Remaining
Man-days remaining area reflection of how much
work remains to be done on the project. Man-days
remaining has nothing whatsoever to do with how
many man-days have been expended. For master
activities that are complete (see master activity 10, fig.
2-25) the man-days remaining are zero. For master
