Awesome, thank you for sharing more info. I figured there was good
thinking happening but since I was just looking at it all by myself, I
needed to ask more questions to understand it.

I do feel a, "Wait, wait, really?" coming on from the proximity of the
panel to potentially wet food work spaces, though. I don't think
that's a hot idea. It looked like there's going to be a center island
with a counter top surrounding that column?

I met Jim today shortly after sending my email, and we did a
walkthrough of the work to be done. So I'll try to stop by 1-2 days a
week to hack on various pieces of the puzzle. I personally work best
with a small team and not too many oblivious bystanders, so if there
are build days / peeps who tend to show up together to work, I'd love
to join in on that.
