If you calculated for the support of the bar joists, you know what the end
reactions are -- You had to *design* something to ultimately support the
joists. My position is that anything beyond that is contractor
And the contractor knows that. I'd give him joist reactions
(CONSERVATIVE), and let him go from there.
In my experience, contractors are often offended when I tell them how to do
And don't overlook *liability* issues.
