Progress without actual start

I don’t think so, but why on earth would you want to claim progress before you’ve started anyway?

If P6 does let you do this, it shouldn’t.

Hi Mr Gary,

Let me explain you the situation: I have "Footings Area XX" as activities in my schedule, the re-bars for those footings are already prepared in the workshop but it will be installed after months from now, so if I put an actual start the duration will be stretched every time I update the schedule without any progress and it will not reflect site situation.
I know that the best way is to split those activities but I cant modify the approved schedule :(

Thanks in advance,

I see. Was the original intention to have the rebar prepared just in time for installation rather than several months earlier, or was it just an oversight not to allow for the rebar?

I would advise applying an actual start, then suspending the task and resuming it when installation occurs.

Cheers,

G

Why you don’t use two activities - different resources, payment for prefab?

Aymen,

Because you are not allowed to change the approved schedule the way to go is by Gary’s suggestion, to interrupt progress. It is a common error in our specs to prohibit changes in the CPM as need be, Scheduling is a dynamic thing, but we have to live within our reality.

Maybe if allowed to include steps within your activity, a functionality of P6, then you can include a step for the purpose of showing what is happening.

Perhaps there is more functionality within the use of steps that allows you to model for your progress per step, if so others more knowlegeable of P6 can provide us with their knoledge.

I believe Dieter can be one of those who can give us more insight into this functionality. He must be used to work his CPM the right way, without such restrictive clauses he missed our so wrong reality.

Best regards,

You’re right, I didn’t read Aymen’s last sentence.

Aymen
In this case steps would be appropriate.
Introduce 2 steps: "Prefab Ready" with a percent complete of %, then another "Completed" with (100-x)%.
Don’t forget to mark Projects --> Tab "Calculations" --> "Activity percent complete..."

Thks a lot my friends for your help,

I think Suspend/Resume is the most suitable for this case specially that you can show the hold period in the bar chart, but in the case that you have more than one hold period Steps become better.

Best regards,
Aymen.
