Excavating for footing/foundation

"Compaction is going to make or break this project."

This should be framed and put in lights at the top of every page.

Didn't chat about warranting bearing pressure. But the building inspector said it would be fine to fill and then dig down 30" from top of new fill.

The best money I ever spent on the house was for a soil compaction test. The City approved us to dig 42" (we are on what was thought to be good fill) and then build but we found the soil was bad. We had to end up digging another 2 feet, but the alternative would have been catastrophic.

Looking at the lot layout , would it be possible to put in a second drive closer to your property line (-4'6") going uphill and still keep the same orientation to the road? I too would hate to have my garage pointed at my neighbors.

Standing where essentially the center of the garage door would be if I dug down. Camera at Eye level looking towards property corner.

Looking at House from same elevation.

I think I would need alot of retaining wall edge, that would far pass $4800.

30 inch not nothing, less than three feet, just do a mono and be done in one day.

prep the pad, then get a backhoe to dig 30 inch footer, throw some rebar in and pour.

somebody mention, five inch of rock, why, just fill up with concrete and be done.

Straight and to the point, thanks bud.

Good point.

In the self storage industry, many of the slabs are monos done by first trenching the vertical trench. Pour that to below the desired finish floor elevation by thickness of edge
form, ie. 2x8, 2x10, 2x12. Then lay vapor barrior and reinforcing and pour slab.
