Without going through the As-Built records I believe we were on programme within a day or two so they should have been able to start work without any problems.
I have had little or no experince of any delay or disruption negotiations on my projects (maybe thats a sign i'm doing my job properly, or maybe im just lucky) so this will be something new to me.
You are using an As Planned v As Built analysis method which is suitable for Sub-Contract v Main Contract disputes.
In my opinion you are going about it correctly.
"First question, do I need to show all of these dates in order to demonstrate how the subcontractor delayed subsequent trades or am i overcomplicating it? "
You cannot have enough detail so show all the dates and data that you have.
"Second question, is this the correct way of going about demonstrating the delay that the subcontractor caused? "
Yes it is BUT and it is a BIG BUT it will show the late start of sub-contract work which can lead to counterclaim from the sub-contractor that they were denied access- so make sure you have the answers ready for this.
If you did deny access because of late finishing of other trades then your case will collapse - in which case it is best not to use barcharts but resort to text and spreadsheets.
Regarding costs of acceleration and mitigation this is very difficult to establish unless you are using your own direct labour - in any case you have avoided penalties /LAD's.
My suggestion is that you calculate what the penalties and your time costs would have been BUT FOR your mitigation and start the negotiations around that figure.

Hi Robert
My definition of a succesful negotiation is when both parties are equally unhappy with the result.
Good luck and best regards.
