Hey Fitz -- first of all, my "thanks guys" was not sarcasm -- I always appreciate the input, including (and sometimes especially) the humorous stuff.

"Perspective."
. . . I personally have become very gunshy to suggest things . . .
Yes, I totally understand. My order is a tall one, not only in terms of TL requirements, but also satisfying the bureaucrats, and it's understandable that you guys would be hesitant to recommend or fully endorse anything anymore.
. . . my experience with not only a cracked slab, but moisture COLLECTING in small pools UNDER my floated floor. . . I THINK you might have a valid concern here. . . seeing as you have a clay bed, and knowing Sacramento weather sometimes . . .
Yup.
. . . maybe use a thick visquine layer like a pool liner completely sealing out moisture, although I haven't got a clue what BID will have to say to this as its a decoupled slab with another FLOATED slab above, its quite un-orthodox RESIDENTIAL construction. At least to me. It would SEEM as though they would require some kind of connection of the new support slab to the existing footing, although I don't know how that could be done. . . Perhaps, a thorough analysis of the costs involved as well as a talk with BID will support a correct decision.
Good idea, fitZ. Maybe I just need to draw up a few different scenarios (submerged float, elevated float, flush isolated) and get their input on each one -- not in terms of expense or difficulty, but in terms of getting their sign-off. It may be that
all of this is moot, regardless of expense or difficulty. I just want to limit my exposure to the bureaucrats because (1) I don't want to be perceived as a pesky pain-in-the-ass (or, as Paul would put it, pain-in-the-arse

) and, as such, I may be less likely to be treated well if/when the going gets tough, and (2) the doorway seems taller when I leave compared to when I arrived... An optical illusion?
If you DO choose to do this, I wish you all the luck, and EAGERLY look forward to YOUR DIARY, as Eric NEEDS another to fill Pauls diary ENTERTAINMENT vacancy when done

I am
totally up for that challenge -- although I'm considering doing an actual "blog" rather than posting every little detail on the forum(s).
I'm STILL wondering though, since Paul has a brick exterior, and had to HANG 5 LAYERS OF DRYWALL from the existing roof support to match the TL of the garage exterior, WHAT ABOUT THAT??

This is exactly why I asked about how these exterior shells relate to the INTERIOR shell as far as TL is concerned. Paul had the equivelent of TWELVE layers total.
This is why I'm wondering how your project would actually match what Paul achieved, considering your existing shell. Just curious.
Good question, fitZ, and one that I have been contemplating as well.
First of all, I believe Paul's panels are thinner (1/2" vs. 5/8"), so mine will be kind of like "install four, get one free." (Even if it's
cheaper with 1/2" boards, it's 25% more work, and 25% more inspections required --
yes, each layer will need to be inspected and signed off.)
Anyway, I'm looking at up to 5 layers of 5/8" gypsum wallboard (or equivalent) on each leaf. 3/4" OSB is about the same weight, and I may substitute that for one or two of the layers -- possibly the first and most likely the second to last). I definitely want my walls and ceiling to "keep up with" the floor, or at least not be the weak point in the system.
