MickeyToo Posted February 15, 2015 Share Posted February 15, 2015 Is there a way to get the foundation slab to sit on top of the stem wall? What I have come up with so far (see the pic), the slab won't overlay the stem wall top and, the sills don't meet in the corners (???). Thanks!

DRAWZILLA Posted February 15, 2015 Share Posted February 15, 2015 Yes there is a setting Link to comment Share on other sites More sharing options...
MickeyToo Posted February 15, 2015 Author Share Posted February 15, 2015 Thanks, Perry, but that places the slab flush to or AT Top of Stem Wall (both are at the same EL). I am looking to place the slab ON Top of Stem Wall. I am half way there. You will see in my previous pic that the the top of the slab is higher than the top of the stem wall (OK so far), but the slab will not extend over and across the top of the stem wall to meet the PT sill (big gap). In other words, I want the slab to behave like it does when it sits on top of the footing in the basement: ON the footing and against the foundation wall automatically. There are workarounds, I suppose, but I just did not know if I was missing something. Easy to do. Thanks again. Link to comment Share on other sites More sharing options...

MickeyToo Posted February 16, 2015 Author Share Posted February 16, 2015 Almost, Mike. Here is a CAD Detail of what I am trying to model. I would be interested to know how you placed the slab in your model, though. Structural slabs are done this way so there must be a way to do it in Chief, I would hope.

evergreen Posted February 16, 2015 Share Posted February 16, 2015 This is as close as I can get OOTB.The foundation is "Walls with Footings"The "Normal" walls are set to "Foundation Walls" - I put them on a different layer for more control. (make the necessary adjustments for the wall footing to fit on top of stem wall)Level 1, Room Specification, set floor finish to 0" and floor structure to "concrete", 3" thick. Make a few more minor adjustments to Cad detail in Elevation to get to exact look/design. Edit: See Attached Link to comment Share on other sites More sharing options...
dshall Posted February 16, 2015 Share Posted February 16, 2015 This is as close as I can get OOTB. The foundation is "Walls with Footings", "Slab at Top of Stem Walls" - Slab thickness set to 1" The "Normal" walls are set to "Foundation Walls" - I put them on a different layer for more control. (make the necessary adjustments for the wall footing to fit on top of stem wall) Level 1, Room Specification, set floor finish to 0" and floor structure to "concrete", 3" thick. The problem with your model is you have a sill plate between top of stem wall and bottom of slab....there should not a sill there.... and the second problem is a 1" slab vs. 4" thick slab........ I can do this quite easily with the exception of eliminating the sill plate on top of the conc stem wall Link to comment Share on other sites More sharing options...
evergreen Posted February 16, 2015 Share Posted February 16, 2015 The total thickness is 4". Did not know how else to go about getting what the OP wanted using CA tools OOTB. Its merely a representation, not how I would do this in the field. Maybe a Video Scott on your take. Link to comment Share on other sites More sharing options...
joey_martin Posted February 16, 2015 Share Posted February 16, 2015 Since no one is going to come right out and say it....No, using Chief Architect you cannot get the slab to set on top of the stemwall like those of us in the Midwest build. You have to use one of the workarounds that some folks are showing, or set the slab to be flush, like Chief wants it, and when doing the detail for that area, pull the slab fill over and move on. I will give you the first piece of advice I give to people that do my training class...stop fighting the program! Chief does what it does, adjust and move on or you will spin your wheels for days trying to get that slab to set on top of the wall. Link to comment Share on other sites More sharing options...
joey_martin Posted February 16, 2015 Share Posted February 16, 2015 You can however, do a mono slab, two pour, on top of grade beam disguised as a stem wall, but then you would have to fake the footing with a slab. Link to comment Share on other sites More sharing options...
Greg_NY61 Posted February 16, 2015 Share Posted February 16, 2015 Mike (Evergreen), I never seen this being done that way... Usually when dealing with situations like that this is the way its being done. Link to comment Share on other sites More sharing options...

evergreen Posted February 16, 2015 Share Posted February 16, 2015 I never have either, just giving back what "MickeyToo" was originally asking... All structures I do are either slab-on grade or a "normal stem wall" Link to comment Share on other sites More sharing options...
joey_martin Posted February 16, 2015 Share Posted February 16, 2015 If we are doing a slab around here...and thats a big if....its usually 3-4 blocks on top of the footing and the gravel fill goes flush with the top of the block, slab poured on top of that. The slab sits on the top of the block. Link to comment Share on other sites More sharing options...
joey_martin Posted February 16, 2015 Share Posted February 16, 2015 Chief has a detail in the library OOTB that details the situation, but won't model the same situation. Link to comment Share on other sites More sharing options...
MickeyToo Posted February 16, 2015 Author Share Posted February 16, 2015 Thanks everyone for your replies. In cold weather climates, special care must be taken to properly insulate slabs, of course. (It was minus two degrees this morning here in New England!) The first pic shows how we did slabs years ago and the second how we would do them today (some elements are not shown such as sill sealer, bug shields etc). Both are simply variations on recommended methods shown here: http://www.buildingscience.com/documents/information-sheets/slab-edge-insulation In addition to the (modest) insulation value the double pressure treated sill provides, we like the fact that it improves the exterior profile of the structure, dropping the siding down and allowing for a full kick board under doors. This method also allows for the slab to be poured after the structure is framed. Lastly, if it ever becomes necessary to replace the sill plate, it can be done from the outside without disturbing the interior space. Growing up in New England with its many historic structures, you learn to think (and design) for the really long-term. Thanks again! Link to comment Share on other sites More sharing options...

DRAWZILLA Posted February 16, 2015 Share Posted February 16, 2015 Nice video Scott, yep the only way is really to manipulate the auto detail, to get the section correct like he wants it unless somehow you use pony walls and a manual slab floor.

MickeyToo Posted February 16, 2015 Author Share Posted February 16, 2015 Hey Scott: That is a great vid! Lots of useful information, and very clever, especially hanging the slab the way you did. (Too bad those slabs are not editable in other views.) Anyway, I really do appreciate you taking the time to make it. I have it bookmarked for future reference. Thanks again!

HumbleChief Posted February 16, 2015 Share Posted February 16, 2015 Scott ,as usual a great video. I'll (try to) remember those techniques. Here's a bad video perhaps showing how to get just the plywood to show? Not sure it answers your question but seems to. http://screencast.com/t/UVxTzDjd Link to comment Share on other sites More sharing options...
HumbleChief Posted February 16, 2015 Share Posted February 16, 2015 Tried again in the framing overview and it worked again. http://screencast.com/t/brpudeSOm BUT it does NOT work when building the structure as in your video. http://screencast.com/t/2fNoK7c9Lr Anyway thanks again and I'll stop highjacking this thread Link to comment Share on other sites More sharing options...
Joe_Carrick Posted February 16, 2015 Share Posted February 16, 2015 I've changed my procedure for Floor Finishes. My Default is no Finish Floor. Then I add Floor Material Regions in each room. They are on Layer "Material Regions" so I can have "Floor Surfaces" displayed (the Slab Floor Structure). I like this procedure for my Floors because I can create much more flexible finish flooring layouts. My Entire Structure starts out with a "Framed Floor" which can be a 4" concrete Slab - which can even have gravel and a membrane under it. I thought this might be more work - but I was having to go into each room and change the flooring anyway since the default never seems to match most of the rooms. BTW, this allows me to change the material in a large room without having an "invisible wall". Link to comment Share on other sites More sharing options...
