Mike -
_*don't you dare*_. The construction of the ceiling grid is not in your scope of work. That is someone else's responsibility. C635, and it's equally challenging C636 are either met by the installation of the ceiling, or they aren't. I'd ask for proof from the ceiling installer.

No to the seismic and I just looked at 9.2.1.3.3.2.


Now I have to look at ASTM C635.

Is this a project with siesmic requirements ? If so the ceiling does have to have supports but that is not the sprinkler contractors requirement.
