Numerous Amount of Positive Float

In the Open Standard

Hi To All,

I need your valuable input regarding the below:

A particular activity (finish of survey work) in the Baseline CPM-PS has an EF on 21 Nov. 2007 with a total float of 42. However, in the Updated Current CPM-PS, such activity appears to have an EF on 21 feb. 2008 with a total float of 840 days.

I suspect that the updated Current CPM-PS portrays an unrealistic amount of Positive Float.

Is there something wrong about it? Kindly advise me how to make the necesary adjustment or to correct it.

Pls. note that we are using P3 Primavera.

Your reply is highly appreciated.
Best regards.

    Just check teh end date of both the projects. Plz also check weather there any mandatory constrainst in the baseline program or not?

    if end date has moved considerably, then TF is also going to get changed.

    Cheers,

    Ravi

    Raviraj is right. Also, check that links to successor activities have not been deleted or that those activities have actually started without the survey having been finished.

    It’s possible that the groundworks were logically linked in the baseline to start after the survey was 100% completed, for example, but that in the event they were able to start while the survey work was ongoing, either by reorganisation of the works or because the logical link was an oversimplification to start with. In this event it may be that there is no longer any successor activity contingent on the completion of the survey and the Float would extend to the end of the project itself. It should then be logically tied back into the activities that are still contingent on it
