Getting overall progress in P3

Hi, I have some questions for the experienced P3 users.
First, I wish to know about the % COMP field (PERCENT COMPLETE) on a resource-loaded schedule for a construction project. The % COMP is based on what?
- Quantities installed?
- Duration consumed?
Second, knowing that this % COMP field is valid only for each activity, how do you get the overall progress? I wish to get the S-curve graph with the planned and actual lines, but how do you get it if the activities have different unit of measures (i.e. LM, M3, EA, and so on)? If you use a unified unit of measure, what report do you use and what data do you export to elaborate the graph using thrid party software, such as Excel (they told me P3 is bad elaborating graphics)?
Thank you very much.

There you can select how you want P3 to summarise the % complete for your activities.
You can choose from duration, resource units or cost.
With a fully resource loaded schedule I recomend resource units for construction progress and cost for overall design, procurement and construction progress.
Enter your % complete at an activity level acording to physical progress. Physical progress is not simply a units completed / total units calculation. For example you may be building a simple building consisting of 4 brick walls. Bricking up the corners takes considerably more time than the in-fill brickwork. Another example is structural steel erection, by just using a quantity method (eg tonnes of steel) erecting one large column will earn you a disproportional amount of progress compared to the infill steel. Factors like this need to be considered when defining your activity breakdown and progress.
Reports can be generated in P3 using the resource/cost profile. - 0Jackie Gilliland ·In P3 be carefull of using activity summarization for determining % complete.
I suggest you use a Resource Control Summary report from Tools/Tabular Reports/Resource/Control. Make a selection for the same group of activities you would like to summarize.
I suggest you run this report and compare the numbers to numbers from a summary bar to check for correctness.
