Foundation Settings

[Ringos]

I am struggling with some foundation settings and cannot seem to figure it out. 

 

I need exterior footings to extend a minimum of 12 inches below undisturbed ground to reach the undisturbed soil.

Then the grade (ground level)

Then 36" of CMU block (because it is in a flood zone and required)

Then the sill

Then the floor structure 12 5/8

Then 1/2 of floor covering

 

The first and second floor is 10' (finished ceiling 120")

 

I set my terrain perimeter to -56 5/8" at contour 0  but I don't think that has anything to do with what the story pole dimensions say.

 

I must have one or more of the definitions wrong below because the story pole dimentions show my grade  and other wrong.

 

These are the definitions I use:

Floor above = the top of the second floor or the ceiling height of first floor plus the floor structure (12" or 16")

Ceiling = the top of the floor sheathing to the top of the ceiling drywall

Finished ceiling = top of floor material to bottom of ceiling drywall

Ceiling Below = the bottom of the floor joist (top of sill plate) to grade (level of dirt)

Stem Wall = top of block wall to top of footings (no sill plate)

Floor below is the grade. Set the floor below at the depth you want from the bottom of the floor joist to the grade.

Set the ceiling below to be how much you want the foundation to show above the grade.

Set the Stem Wall height to 12" The stem wall height is the height of the concrete block wall from the top of the footer to the bottom of the floor joist. In Virginia Beach, exterior footings must generally extend a minimum of 12 inches below undisturbed ground to reach the undisturbed soil, and also to or below the local frost line, which is 12 inches in this area.

The grade level needs to be 36" below the bottom of the floor joists but it seems to pick a random place in the middle of the floor.

The grade level in the story pole dimensions is set in the Story Pole Dimension defaults under the locate elevations panel. It is at the very top. It isn't based on where the actual terrain is located. May not be what you are needing, but it is worth a check.
