MN_JohnH Posted May 20, 2019 Share Posted May 20, 2019 I am trying to construct a home on a slab and I am going to use ICF walls around the perimeter with footings. The bottom of the footing needs to be 52" below grade and the interior of the icf walls are filled in and the slab is poured either on top of the ICF walls or inside the ICF walls. All the tutorials show how to make a slab foundation or a crawlspace but I don't see an option for a stem wall and footing below the slab without a crawlspace.

A crawlspace has the dirt removed, the other does not. 26 minutes ago, solver said: What's the difference? A crawlspace has the dirt removed, the other does not. Well that's the question I guess, how do you remove the dirt and make the floor above to be a slab? Lets say slab inside the ICF wall. Link to comment Share on other sites More sharing options...
Michael_Gia Posted May 20, 2019 Share Posted May 20, 2019 Compacted soil or fill. Pour slab anywhere you want. We usually just fill the whole thing with 3/4 net. No compaction needed. No headaches with sinking etc. Link to comment Share on other sites More sharing options...

Awesome! thank you. Link to comment Share on other sites More sharing options...
MN_JohnH Posted May 21, 2019 Author Share Posted May 21, 2019 Now if I draw another interior wall and I want it to be a bearing wall shouldn't it show a footing under the slab on the foundation level? I can get it to show a footing by changing it to a foundation wall but it still doesn't show it on the foundation level. I need a thickened area under the slab under that wall.5-20-19 fresh.plan Link to comment Share on other sites More sharing options...
glennw Posted May 21, 2019 Share Posted May 21, 2019 You have the settings correct - making the wall a Bearing Wall and Create Wall/Footing Below. You just need to Build foundation and the footing will build in the foundation. The wall will look like a normal wall on level 1 and you will have a wall/footing in the foundation. Unless there is a pressing reason not to, I would always leave Automatically Build foundation toggled on. Link to comment Share on other sites More sharing options...

Unless there is a pressing reason not to, I would always leave Automatically Build foundation toggled on. That works except I really don't want the same foundation stem wall that is on the other walls. I just want a thickened footing under the slab. I can go to a cross section and drag it up but then the auto foundation will fix it later if I rebuild or have it on auto rebuild. It would be nice if I could just change the foundation on that one wall to a thickened footing under the slab. I can do that by just changing the upper wall to a foundation wall but then it doesn't show on the foundation plan. So maybe leaving it as a non bearing wall so that the foundation rebuild will not mess with it and just drawing the thickened slab footing under it in as Solver said, is the only option...

Yes that is what I get too but I just wanted it to show on the foundation plan view. If I build the foundation I get it on the plan view but I get the stem wall with it on the cross sections.. After thinking about it, I think the thing to do is just build the foundations automatically and then when it is all done, go to cross sections and modify them, I also almost always have some step footings too so there are other things to change that won't rebuild properly. Anyway, I think I am good here, thanks for the help. Link to comment Share on other sites More sharing options...

That is almost always the case for me, therefore I may use auto build roof and foundation once and then turn auto off and edit any differences. 1 Link to comment Share on other sites More sharing options...
Archnot-Boltz Posted May 23, 2019 Share Posted May 23, 2019 The problem with floors is you can't re-frame just one section (unless you re-draw each floor member of that section manually). Chief only allows you to re-frame the entire floor which screws up any customizing that you've done with the framing layout. Makes additions and remodels more difficult. bB Link to comment Share on other sites More sharing options...
