We basically just want to be able to see how the commercial
contractor does the Chicago grid sheetrock ceiling stuff --
including what materials to buy, what spacing is required for
proper support, etc. -- all of which I am sure is simialr to a
regular drop ceiling but is not the same.

Sorry, exact same process. The material is slightly wider, but
other than that it is identical to hanging a drop ceiling.

Well, I assume that one difference may be in the spacing of the metal
framing when hanging drywall on the frame (including 1/2 inch or 5/8 inch
drywall) and the required number and size of the support wires. I know with
a regular drop ceiling the framing can be done to allow 2'x4' or 2'x2'
openings, but maybe (for example) the Chicago grid requires 16-inch framing
for the sheetrock.
