Please Help Sill Plate Problems

Triple J

Ok my customer insisted on a monolithic slab so the concrete man poured it and several of the form boards bowed out about a half an inch in some places. So would you set your sill plate to the outside of the bow or straight from corner to corner. Keep in mind that the house will be sheathed with osb and then bricked. opinions please!

What did your carpenter think about it??

I would set the sill plates according to the dimensions in the plans, and make sure everything is square.

I have had to frame houses before on a bad foundations. Sometimes the plates were overhanging the foundations, sometimes they were inset, sometimes both just to get the house square.

Remember if you set the plates out farther, the house will be wider, etc., And you will have to compensate with everything else later, like trusses, etc.



Also did you check if it is square if you run them corner to corner?

How does a homebuilder not know this?? do this sound like a homebuilder question?

I agree. set the sill's as to plan, where the slab extends beyond the sill take a diamond blade saw cut down about 1" and 1" back in to make a small ledge, when you install your termite sheild bend it to that shape and then bring your wall sheathing down below your sill. I'm guessing the brick ledge is lower than the top of the slab.so it will not be visable.

Yes I'm a homebuilder who has never built on monolithic always block and slab. But I would have loved an opinion. I asked my local buddies answers. The house is square corner to corner. The corners did not move just two form boards in the middle of the wall bowed where they were braced. the brace did not hold. You would be surprised how many answers I have gotten.

The correct answer for the dimensions you stated are to run the plates true, period. I make it a point of pride that we frame square and true.....besides, the 1/2 inch is less then the brick spacing off the ledge.

If the extra inch isn't a deal breaker
for sheathing, siding, or rafters,
I would be inclined to let the corners
hang.
Other wise, buletbob has a good solution.
I just don't like a ledge between the
finger space and the wall.
It's a potential moisture catcher.

Also even if he wasn't using brick, by the time you add sheathing and siding he would be about a inch out over it anyway. So it would still be covered.

True, but where is the brickshelf? Is there one? I didn't hear any mention of that.

I try to stick with the plan as much as possible. Deviating from the plan has a funny way of creating other headaches down the line.

Then again...sometimes the plan is wrong and you HAVE to shoot from the hip.

Decide, and let us know how it turns out.

Just want to reiterate the fact. Go with the plains. Everything else can be covered up one way or another.

You need more exp. framing.

neolitic

Yeah, by all means,
get a good horse and
a buffalo rifle and
go for the plains!

I would definitely go by the plans if at all possible. If you don't, as mentioned above, it'll haunt you throughout the project. The foundation should be Square, True and Level also (in the perfect world)

Thanks for the comments they were very helpful. The house is working out great. We finished the exterior walls now on to the flooring system for the bonus room.
