Dear All,
I have found that SF is very important in Resource Constrained scheduling though I wonder as to why there is a lot of criticism about it.
What are your comments on that considering the modeling of subgrade operation where all activties can work as FS other than water sprinkling and rolling as sprinkling can only be done when the rolling can be started right after it.
Best Regards

Oldest first- 0Frank Borcherdt ·I would use a FS with ZFF (as late as possible) constraint rather than a SF. Due to the short activity durations in your example you are unlikely to experience the issues encountered when activities are executed out of sequence, the schedule is updated to reflect what’s happened and you get illogical dates on these activities. Having helped several planners resolve this I am not a big fan of SF.
- 0Rashid Iqbal ·Thanks Frank.
I totally agree that Zero Free Float is very good and quite logical though it works good in schedules that do not require resource levelling. Try it with resource levelling and you would see that ’sprinkling’ will not tail follow ’rolling’.
If you know as to how i can attach a pdf with this forum posting, kindly let me know and i will attach a sample which would give you a better idea of what i am trying to say.
