Regarding deck collapses....There have been several more than the one in Chicago.
The problem, generally, has not been the member sizes (floor joists etc) but rather the connections between the legder and the main house and lateral stabilirty of the columns.
Generally, contractors will only...
I have done them both ways....supported by the framing and on a slab. It really was a function of the size (and therefore the loading) on the tub.
If you do support it on the deck...using galvanized joist hangers (or stainless steel) is critical since the tub will have some chlorine in the...
I'm glad to see the contactor decided to start cutting out the concrete before you told him to.....or at least I would have told to remove it and start over.
You might be able to justify not removing the footing by adding pins and dowels but I would not feel comfortable with this solution.

Answer to question #1.....I would pass on the person, unless the side job is not related to his/her full-time position. For example.....a structural engineer during the day......a bartender at and on weekend...or better yet and office manager during the day....stripper at night (now her I would...

Think about this....Do you remwenber the commercial for crazy glue where a man stands beneath a heavy object (I think it was an elephant) "glued" to a hanger with crazy glue?
Now apply this to your problem, You have a 100K truck hanging over your head that has a oval hole thru the web and...
You really nee to input this condition into a good 3D program, STAAD...RAM ADVANSE.....Risa 3D.....SAP, etc.
regading being conservative with your design.....belts and suspenders.
It is not uncommonm for CMU foundation walls not to be filled soild be grade, ie hollow.
Personally, I would rather use a cast in place foundation wall rather than CMU - hollow or partially grouted.
If you are trying to transfer the end reaction of the two C15's to the foundation wall, you should be a ble to rely on the shaer values for the epoxy anchors, provided you extend byonmd the opening(?) enough not to affect the opening.
You could also install short C below the C15 as a...
It has been my experience that you don't want to "show-up" the builing officials. Especially if you plan to work in the area again. You don't want to "bruise" his ego.
