EOT Claim analysis in P6

Hi,

I am working on an EOT claim submitted by the contractor recently. They are claiming for 35 days extension for the project. The project was suspended for 10 working days by client. Even though the project was on hold, contractor was progressing the works to catchup his delays in the other area.

My question is how can I analyze this claim in P6.

What I have done is

1. Updated the progress (Applied the actual, thinking that everything was done as planned) on the contractor’s baseline schedule using the data date as the beginning of the hold period.
2. Then run the “schedule “ using the data date as the last day of the hold period)
3. I am getting a result of 11 days (Total float = -11Days)

Is this the correct way to do this sort of exercise or need to do something else?

Thanks for your help,

Johny
