Hi, the project finish date is almost 2 years delayed, which constraint shall I use in P3? The data date after I put the constrainst will be the project start date. When I use the mandatory constrainst, the total float will be zero for that activity while the successors has negative floats. When I use the late constrainsts, it has no negative floats. When I use the early constrainst, the applied activity has negative floats. So which one shall I use. I want to show the result of these constrainst to claim Extenstion of time. Can you elaborate the difference between them?
1. Early constrainst - start
2. Early constrainst - finish
3. Late constraint - start
4. Late constrainst - finish
5. Start on
6. Expected finish
7. Mandatory start
8. Mandatory finish
9. Float constraint - zero total float
10. Float constriat - zero free float
Thanks guys.
Hi Num
Constraints should never be used to demonstrate a delay to the works.
The first thing to do is remove ALL constraints and reschedule so that you have a reasonably realistic critical path.
