Hello....
Consider the Situation.
Activity 1 - Unclassified Excavation - 150days
Activity 2 - Excavate to lay storm water pipe - 45 days
Activity 3 - Lay Pipes - 30 days
Now the execution would be like Unclassifed excavation starts on and after a lag of say 7 days Excavation for pipeline starts and once again after a lag of 7 days from Excavation for pipeline Laying Pipes start; all activities running parallel.
ie the relation ships are:
Activity 1 (SS Lag 7) Activity 2
Activity 1 (FF Lag 2) Activity 2
Activity 2 (SS Lag 7) Activity 3
Activity 2 (FF Lag 2) Activity 3
Now once scheduled the dates are held by the Finish Links
(driving) as such the start dates of Activity 2 & Activity 3 would be later than what was actually intended with the SS Lag.
One solution now is to break up the activities into two or three parts.
Now suppose I dont break it up and go ahead and try to update the schedule....
Suppose Activity 1 starts as planned now after a week (7days) Activity 2 starts as such I give an actual start date to the activity and now I use remaining duration to update the progress. But now you see the FF driving relation still exists and as such my acivity duration increases from 30 days to some where around 145 days
(150-7+2). I thought I would use suspend and resume function of P3 but once again the programme permits suspend and resume on an activity only once.
Any comments on this situation??
