How To Layout Square Wall Framing On Concrete Foundations That Is Not - Home Building Tutorial 

Thank you for this video and your time! I’ll definitely be using this as a guide!

Interesting video. How are you finding that interior square to pull off of for measurements? Are you pulling from two adjacent sides that you deem the most straight, finding the approximate center, and then rounding up to the nearest foot when you actually put your square down for an easier measurement later? Basement foundations would make this a more challenging method I presume. Do you know why this happens with slab foundations? I know that building a 7ft high basement wall can cause some errors by the time you reach the surface, but on slab? Does the pressure from the concrete curing cause the exterior boards to move around a little bit, or does it have to do more with improper installation of the foundation?

In your video, you mentioned replacing a 2 X 4 with a 2 X 6. If you use this method and place the inside of the 2 X 6 on the square line and then trim the outside to match the concrete foundation, would this cause some large challenges for the rest of the build ?? I see that some wall studs would have to be individually ripped or furred out but what else can I expect ?? Thanks for both your time and video.

If the framing base plate is hanging out side 1"in ina 6" wall will it be unsafe building?

How much will plate overhang on the concrete would be acceptable in your opinion?
