Close, but still more digging.
Decided to just go down 6” more overall and at the end I need to go 10” more. By going down 6”, it will ensure I have enough height for the future air compressor and I should be able to walk under the beams without hitting my head. I will have 14” of backfill and concrete on top of the footers so plenty of depth between the floor top and top of the footer. Only thing is I’ll have to have a concrete ramp poured to go from 17” drop to the floor. I think by pouring a 5ft long ramp, that will give me a 3.4” drop per foot ramp, and I will have 9ft between the wall and end of the ramp inside the bunker. Should be plenty of room for driving my riding mower in the bunker.
Here’s some progress photos



Once I get it to grade, I’ll clean the trenches out and then it’s time to pour 2b limestone in the trench to compact it, and then I’ll pour 4” of stone over the whole area for a 3.5” concrete pad/slab. Since I’m not driving a car in here, 3.5” concrete should be adequate.
