ICF Exterior Walls - Open and Boxed

Recommended Posts

If I start with a new plan, it will default to a different exterior wall type, and then I can box it.  But that is not what I want.  Below is an image of the wall type with the footer that I want to make, but I cannot get it to work.

Uncheck Slab Footing.  When you check slab footing you are telling the program that you want the walls to be used to form the footings for a monolithic slab foundation so as soon as you enclose a room that's what you're getting.  The slab footings should go on the foundation room below if that's really what you want but should not be spec'd for your main walls.

 

NOTE:  You may also have to increase your ceiling heights if you make this change after the fact.

Once you enclose your room you can also just open the room up and increase the ceiling heights instead of unchecking Slab Footing.  I still say that you shouldn't be using that checkbox in this situation as the foundation belongs on the floor below but I wanted to point out that you CAN have that checked and still get what you're after.  There's just no good reason to do it that way IMO and its really not how I think that setting was designed to be used.  Again, once you enclose the room, Chief automatically converts the room to a monolithic slab and when it does that it changes the ceiling height to zero.

That just doesn't make any sense.  Why Chief would allow you to make the default settings, and then it doesn't work.

 

It does work.  I just don't think you're using it in the right way.  I would suggest you get in the habit of using the Help files...

I should be able to sketch my ICF walls with the specified footer and calculate the total amount of required concrete.  As of now, I don't see how to do that.

 

 Exactly what type of foundation/floor structure are you trying to draw?

For now, I’m just trying to create a simple 4-sided building as I showed in my first post, with a footer, and calculate the total amount of required concrete.  Then, as I add windows and doors, etc., I should see the amount of concrete decrease (automatic update).  I want to establish the methodology on how to do this in Chief.  I have watched a lot of the online videos, but I didn’t see anything on how to do this.

I checked Foundation Wall, which produces a footing which you may adjust for size -- and I assumed that's what you did too (should have looked at your image).

 

If all you want is the amount of concrete -- which is an estimate, so you will need to verify that the forms you are using match to what Chief is calculating, an ICF wall with Foundation Wall checked should work.

Chief should calculate the amount of concrete based upon the dimensions the end user entered for the exterior walls and footer and show in a table, somewhere, the required cubic feet.  I’m learning Chief, a trial version for 30 days, and spending also 30 days to learn Softplan with its trial verson.  Softplan does this with ease, as shown below, but I cannot figure it out in Chief.  I want to design ICF homes, and I have to determine which software works the best.  I like them both, and I’m not an expert in either one.

What are you unable to figure out?

 

Have you reviewed the material list? It shows the concrete used in the wall and footer, and it changes when you add openings.

Change the default wall to ICF, check Foundation Wall, change the footing (under Foundation) as needed.

 

Draw your walls. Make the room Open Below, or just leave the default floor structure as is -- should default to wood.

 

But, as Michael said, this isn't the correct (Chief) way to build a structure. Explaining a bit more about what you are building will help others help you.

Honestly, there's nothing really wrong with what you just spelled out but you also correctly left out the checking of the Slab Footing box.  That's all I was saying...don't check that box unless you want Chief to treat that wall as a footing for a slab.  And again...if you make this mistake you're going to end up having a room with a zero ceiling height as well as a monolithic slab foundation.  You'll need to fix those settings. 

 

P.S.  By "you", I don't mean you Eric, just any yous who might be reading along : )

solver,

 

I was able to replicate the enclosed ICF walls, based upon your guidance.  Thank you.

 

What I am trying to design is an ICF home, but I am starting with the exterior wall along with the footer.  But you stated that this is not the Chief way, and I don’t know what is.  I thought starting with the exterior walls was the right approach.

 

My approach to modelling is the same as if the contractor was building it.  Footers/piers and ICF wall (with window/door cut-outs), floor joists, subflooring, interior walls, roof trusses, roof, etc.

 

I guess I will have to watch more Chief videos to figure out the Chief way. :)

Not exactly.  The ICF will start on the footer, and the floor joist will integrate to the ICF wall via joist hanger.  Here’s an example.  There are several methods of doing this, and they vary depending if it is bearing or non-bearing.  I don’t know if Chief can show these types of joist hangers.

      Hello, I'm trying to draw some ICF walls, how do I get rid of the sill plate and space?
      Thank you

      I am posting this as FYI, and it has to do with the creation of ICF walls.  I have been learning Chief and Revit at the same time, and the one thing that I really like about Chief over Revit is that Chief does have default ICF walls, whereas Revit does not.  You have to create your ICF walls in Revit.  I was just amazed that Autodesk did not have this OOTB functionality.

      Community,
       
      I have two questions.
       
      1. I used ICF blocks on a footer to build my foundation wall, and the bottom of the first ICF block should mate with the top of the footer.  However, when you look at the attached image, the first ICF block is very narrow, and I placed red marks through the top of the first ICF blocks.  How can this be corrected?
       
      2. How can I make the floor joist part of the foundation wall?  Notice how the floor joists are above the ICF foundation wall.  Thanks in advance.

      Community,
       
      I have been watching a lot of Chief training videos on how to make walls, foundations, and floor joists, and I am trying to figure out a way to integrate joist hangers into the ICF wall to connect the floor joists.  In the real world, the footer is poured first, then the ICF wall erected, reinforced, joist hangers inserted, and braced, then concrete poured into the ICF wall.  The ICF wall will start on the footer and rise all the way up to the ceiling of the room, (and this will include the encapsulated crawl space), for example, 13 feet high.  And the joist hangers will be, for example, 3 feet above the footer.  Can Chief do this?  Thanks in advance.
       
      I have inserted an example of an ICF with a floor joist attached.
       

       
      I found this image from an older post, and it shows one type of hanger that comes with Chief (ICF wall ledger at floor), but that is not in my library.

      I've got a problem with unwanted steps in my footers. 
       
      I've checked the foundation tab of the wall properties for each wall, and I've checked the room properties to ensure the stem wall depth and footer depth/sizes are all set the same.  For whatever reason, they are not drawing the same depth footers, and I'm getting these really awkward steps.  They weren't like this in an earlier version of the plan, and I have no idea how they got broken or how to fix them.
