Walkout Basement Floor Issue

[JKEdmo]

Hello,

 

Week 3 or so of my Chief journey.  Going pretty well.

 

Anyhow, been working on an as-built model with a walk-out basement.  I would like to have the basement floor be concrete slab-on-grade with the wood framed walls sitting on top.  It appears my wood walls are going through the slab. I'm a bit stumped as to the solution.  Any help would be appreciated.

 

I have attached the plan file.

 

Thank you again,

 

Jim

No, with a separate footing pour.  Similar to this detail:

To achieve this, walkout wall is modeled as a pony wall.  Framed wall up, poured concrete foundation wall under.  Set the junction height at the appropriate elevation.

 

But yours is an as built.  Could be anything going on down in the dirt.

Thank you both Gene and Eric.  I'll take a closer look at this in detail tomorrow.

If I am not mistaken,  you want the Retaining Wall on footing at one side of foundation and a mono slab footing on the opposite side.

 

This is the reason that I believe the floor plan of the walk out basement should be on level 1 (not level 0).  If the walk out basement plan is on level 1,  this allows the mono slab foundation to be on level 0. 

 

Now define all footings at level 0 to be mono slab footings and the retaining wall is defined as a foundation stem wall.  A bit tricky....  probably very difficult to build auto so this is a manual build.

If I understand correctly, which is a big if:

 

Referencing the Default Settings>Floors and Rooms>Floor Levels>Floor 0 dialog box, the basic issue is that the Absolute Elevations>Floor value needs to be coordinated with the Relative Heights>Stem Wall value. You can either:

1. Adjust the Stem Wall value:

 

2. Adjust the Floor value:

Isolated, that walkout lower wall is looking like a 3-story house built on grade, no cellar or crawlspace under.

 

i'd be surprised to find there's only an 8" deep footing under it.

 

A lot of the Pacific NW has houses on piers and beam foundations.

Thanks everyone for the help on this.  I adjusted the stem wall height and this works for my purposes.
