Adding an additional perspective. I'm on the board of directors of my condo corporation, and we have to deal with escalations from time to time for various claims, and threats of lawsuits, etc.
From what I've seen, a perspective of I've collected a bunch of evidence that I'll refer to, but not actually provide, does seem to correlate with those with baseless claims, or those possibly trying to scam the corporation. This is anecdotal from my experience, but has happened more than once. In this case, it might be slightly irrelevant, because the insurer probably has easily verifiably facts on their side to know the calls happened, and the computers were a problem, etc.
But something like the invoice that's being claimed, is an important piece of information. We may want to know what work was done, was it in scope of our responsibilities, call the plumber and verify their credentials, ask them for details not documented, etc. If we have any suspicion the individual is trying to defraud us, not knowing the evidence that supports the amount claimed makes it really difficult to agree to. And if this goes on for a long time, it may be difficult to follow up on those facts.
I don't know about the rules around arbitration specifically, but if this hadn't settled, there may be deadlines involved just like the courts. And anything your doing to make the other side unprepared or to ambush them may be held against you. I don't know that it means you have to lay out everything on day 1, but I wouldn't want to leave anything to the last minute and allow even an argument that I prejudiced the other side by knowingly withholding relevant information.
