Suspend and Resume activities more than one time

Use the calendars non-work days to record the interruptions. Because Primavera software does not provides much visibility on the exception table, perhaps none visibility other than displaying lengthy reports then keep a log of the interruption days and, the calendars and activities impacted by the calendar.

Depending on how the interruption affect the activities you might do it within a single calendar or perhaps a few. Some calendars such as 24 hours 7 days week for activities such as deliveries and curing will not be impacted.

In this way when you update the schedule actual activity duration will be real. 

This is similar to the recording of rain days and the impact on the schedule. You only know rain days after it happened, same with the interruptions you do not know when will be finished. 

For a TIA you can determine prior to impact the expected project finish date and then include the non-work days to get a projection on the impact of these non-work days. 

Remember such interruptions or disruption might have the additional effect of having to re-mobilize plus an impact on productivity. It is not easy but it is mostly about good documentation as the burden of proof rests on the claimant. 

If you will claim reduced productivity then you will need to keep time distributed data for work performed, resource usage and compare using the Measured Mile method as to substantiate your claim. 

Ibrahim,

Most software I know either only allow for a single split/activity or multiple splits but a single split/activity/update period therefore under multiple splits the calendar option is what I use. If you find some other way it will be good to know.

Only other solution I am aware of, which is far from ideal, is to split each suspended task into 2: pre-suspension and post-suspension. Then you can control the individual suspension dates with early start constraints on the post-suspension element.

It causes problems with comparing vs baseline, and can be more work than creating individual calendars if you have to split the cost/resource loading too.

I read all your comments, but can you share with me when we suspend activities of project, how about the tracking progress because in baseline we did not have suspend?

Thanks,
