Thanks for the clarification - now we can see what you are getting at.
A point to remember for the future - If you want the right answer then ask the right question.
There are two types of extra work:
1. Increased volume of the original tasks
2. New tasks not included in the original programme
Or any combination ot the two.
Extending a task because of increased volume is easy if the task is resource modelled - if not you can re create the effect on a spreadsheet like this:
Original Volume / Hours per unit / Gang size = Duration
Copy the formula to the next row and change the Original volume to the Actual volume.
You then have to consider the Gang size to see if the extended duration can be reduced.
Be aware that your programme task duration will not the same as the result of the original volume calculation - this will create difficulties if the calculated durations are longer than the programme tasks.
Inserting new tasks is equally simple by just creating new tasks and linking them in.
Remember two things:
A 50% increase in volume will not necessarily genrate a 50% increase in time - it could be less by using up float or it could be more by going over holidays.
It is the contractor's duty to mitigate delays - whoever caused them - provided no extra cost is involved.

Ok i talk about reschedule because in this case the original work plan suffer changes by Mostadditionalwork andthereforeworktimeis prolonged...not is only a update...cause a contract witha valueof $25.000 will cost now with the additional work (amounts) $35000 and the original duration of 6 months is now 8 months...take that like a fictitious example...

Hi Jhorbam . Yes i concur with Mike and Raymund. Maybe the following is helpfull.
Reschedule
I consider a reschedule as and when the applicably schedule is no longer meaningfull. This can have many reasons but the most common are that the scope of work has significantly changed and that the project is far behind schedule. In this case you reschedule so that the requirements of the stakeholders are met.
Schedule
I schedule as and when i have updated the schedule with % complete. remaining durations, actual start and finish dates and have set a new data date.
Trust this helps

Hi Jhorbam,
You meant to say that you will view together the Scheduled % Complete (Program Percente) with the Performance % Complete (Executed) for comparisson.
If this the case then you are updating your program.

Hi Jhorbam
I think you may be confusing "Reschedule" with "Progress".
Please clarify.
