How to Square Concrete Footings and Forms on Sloping Hillside - No Complicated Math Here

www.homebuildingandrepairs.co... Check out some of our awesome construction and building foundation videos by clicking on link. In this video I will be providing you with a simple and easy way to check your hillside concrete forms to see if they are square. Keep in mind that the upper footings or forms will need to be level and the same for the lower footings other wise your measurements could be inaccurate.
How To Adjust Forms To Create Square Building Foundations And Patios

I can appreciate trying to keep it simple, but there's a little more involved in the sloping example because the parallel distance along the grade is longer than the parallel distance along the level horizontal distance by the reciprocal of the cosine of the slope angle.
I would suggest to only stake in the two parallel form boards without the two cross pieces first, then do your first two layout marks on the form boards to establish one side. Then just either use the Pythagorean theorem or trigonometry to establish the exact location of the third corner, then the fourth corner is established with the parallel distance. Then you can put in the two form cross pieces at each corner exactly where they supposed to be. This eliminates all the wasted time going back and forth with the cross measuring.

Hey greg, how would you go about framing a 26'x40' roof on a two story house (no trusses)? Is it possible? Do you have any videos I can watch for more info? Thanks in advance!

Yes, go to the website and check out the roof framing section. www.homebuildingandrepairs.com/framing/roofs/index.html

This also assumes the top 2 are perfectly level,and the bottom 2 are also perfectly level......rarely the case on a slope.

Yes, good observation and I also mentioned it in the video.
