Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Do you think that the critical path change during the project,

If you Say no, that’s mean you like to use the method of (impact as planned) for delay analysis.

If you say yes, that’s mean you like to use the method of (Time Impact Analysis) for delay analysis.

 

sure that the critical path change during the period of the project, and it’s not fair to use the first method (impact as planned), because this method is built on the idea of to see the impact of the delayed activities in the base line program, which is have a critical path not reflecting the true critical activities on project anymore at the time when this delay occurred.

In other meaning, the critical path which is in the (updated progress program) is more accurate and reflects the actual critical activities on site.

So, take care of using the (impact as planned) for delay analysis even if it’s agreed method or old method

Hi Khalid

Let us get our terms right first.

My definition of Impacted as Planned method of delay analysis is where a delay event occurs during the progress of the work and the duration of the delay event is impacted on to the affected activity - thus showing the likely effect of the delay on the completion date.

If you agree with this then it is the ONLY method that can be used when work is in progress.

The critical path will change after the impact of the event ONLY if the event uses up enough total float to affect criticality.

It should NEVER be used for forensic delay analysis when work is completed.

I have no idea what you mean by Time Interval analysis unless you are referring to Windows or Snapshot methods which - outside of USA - are totally debunked as valid delay analysis procedures.

Best regards

Mike Testro
