specs on natural stone install

[mark999]

I lost my copy of the TCNA handbook and never had a MIA/BSA handbook.
I need to lead an architect to the following specs.

1) L 720 for natural stone install
2) second layer of plywood for natural stone install

Would you please advise where these can be found and if possible which section or spec. number.

Thanks,

Mark
