Hi Mike

Assume a floor in building construction projects where the last activity is tied to an activity named as floor completion(Dummy 1) and that floor completion is tied to respective sectional completion and finally sectional completion is tied to project handover

Please be noted that i might be wrong but i proposed to get the correct logic through discussion in this forum
.-Intermediate dummy activity

Hi shahul

Whats all this about "intermediate dummy activity"?

How does that fit into proper planning unless it is a "Time Risk Buffer".

Please let us know.

Best regards

Check your logic, you probably have too many activities without successors. Link them to a finish milestone that the project is aiming for, or it may have several finish milestones. Do a view log in P6 when you schedule and tidy up all the mess.

Hi, Arun.

I’d approach it by identifying which critical tasks have the most drag. Then I’d compress the schedule by shortening them up, splitting them, or fast tracking them (SS relationships) wherever I could without damaging the project by increasing risk, etc.

Then if the critical path has changed, I’d check which activities now have the most drag, and I’d keep repeating this process until most of the float was gone and I had a shorter (and often more profitable!) schedule. If it’s shorter but not more profitable, I’d see if a shorter project has value for the customer, and, if it does, negotiate an early delivery incentive.

Unfortunately, Primavera (unlike Spider or MSP with an add-on) doesn’t compute drag, so you’ll have to do the drag calculation "manually".

Good luck.
