After stumps and rock removel, mound needed to be leveled, tried compact tractor which started out good till we hit some hardy rocks, not that I was surprized not to much dirt around here. I had to get some larger equipment which still had trouble.
The garage build site was was started in november 2010 with one big problem, a large boulder on the mound which needed to be removed where the garage is to go. Here are some pictures.
I will be pouring a monolithic slab in about a week looking for recomendations on saw cutting slab. size is 30 x 40 right side of garage will be poured flat left side between two overheads have a slight pitch to 40" trench drain. I don't know if this layout is best?
It's been awhile since I installed mine 21 years ago. 7/8 might be more work but is possible, I ran some in between floor joist 16" on center, and some in concrete can't remember 16" or 24" centerd.
