Thanks very much for clarfication , my next question is, Suppose I am a contractor work in a tower and I am now in the implementation phase of floor no.16 and received instruction from the owner to change the overall design of this tower,the time elapsed of the project was 18 months .. some delays resulting from the contractor by 4 months and was probably in the floor no. 20. Whatlogical methods to calculate the delay caused by the instructions and what we consider delays caused by the contractor
The client is trying to ascertain concurrency between his delay and the contractor's delay.
So this is what you do:
1. Create an event schedule where all the client instructions - including the one that you consider to be "most important" - and all the contractors delays are on an excell sheet.
2. Calculate the impact date of each event - that is the EARLIEST DATE THAT THE DELAYED TASK COULD START after the event including design and procurement etc.
3. Find the impacted event using UTID - there may be more than 1.
4. Sort the excell sheet into ascending date order of the Impact Dates.
5. Impact each event on the baseline in turn and note the delay effect - if any.
Remember that an event that causes delay will change the critical path so the next event may not have any effect.
Better still by my book on Basic Priciples of Delay Analysis where the full process is described with worked examples.

Hi Medhat
It seems that you are asking for a basic tutorial in delay analysis - in which case buy my book.
In an Impacted as Planned analysis every event has to be impacted in strict chronological order of the Impact Date of the event.
No delay event can be treated in isolation but must be considered within the order of all the others.
SO - Set up the events schedule and impact ALL the events in strict chronological order - its the only way.
