Have activity 'B' be the FS predecessor to activity 'A'.  Then apply a lead equal to the duration of B + 1.  Now if activity B gets postponed by other predecessors, A gets pulled along also "just in time".  Notice that A will never drive B since its not a predecessor, but its early dates will always immediately preceed B.  This works whenever you have an activity with shelflife.

I’ve never levelled in Open Plan and now I don’t have the software to try it out, so can’t help you there.



Would a work-around be to combine instructions a and b into one? Maybe with a zero-resource activity acompanying if you need to show the specific isolation date?

In Open Plan set Resource Scheduling ’Type’ on the Advanced tab of the Activities dialog box to the value of ’Immediate’. This will cause the activity to be scheduled immediately after it’s logical predecessor. Use this sparingly.

If your software, Open Plan or P6 have zero float constraints as Suretrak does then you can schedule the successor activity with a f-s link from the predecessor along with a zero float constraint then with a lag on this link you probably will get a mandatory lag.

To see if this holds true after resource leveling try it in your software, then run the resource leveling and let us know.
