(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.
Dear All who can help;
I am a student studying delay analysis and i have a hypothetical project whereby a project has been partially completed and the two parties are in dispute over contract continuation. I do not wish to discuss the legalities of the topic as my assignment is in regards to the delay analysis, therefore my question is:
Do i need two types of delay analysis? One to calculate the delay of the completed phases of the project and one to project the delay of the uncompleted tasks?
Any help would be greatly appreciated.

Hi Ess
You are correct - both the methods I suggested require a critical path.
If the completed work has been calculated by "progress complete %" up to a dated data line then any logic left of the line becomes irrelevant.
Logic to the right should remain in place.
If that is your situation then the time impact method for future work should be OK.
If you cannot remove the progress % on the completed tasks and restore the logic then you will have to rely on an As Built v As Planned method whereby the Planned durations are compared to the As Built durations to show the degree of delay that has occurred.
This will not show cause and effect and becomes a global claim.
If the as built information is complete then you can attempt a collapsed as built method but this is very subjective and does not show concurrency.

Thanks Mike,
Your book will be purchased! First may i ask, does Time Impact Analysis not rely on Critical Path Method documentation? My understanding is that it is. In my assignment i only have baselines and activitiy durations, there are phases of the project where a critical path has not been defined only activity durations are stated.
Thanks.
Hi Ess
I am using UK definitions not US - see SCL Protocol 2002 Chapter 4.
For completed work it depends on the quality of your as built records - if they are complete then a Time Impact Analysis will work.
For work that is in progress but delay events will impact some time in the future then an Impacted as Planned method is required.
These are all described in my ebook Principles of Delay Analysis - download from my website www.expertdelayanalysis.com for £25.00.
