Nice.
Wish we had some soil like that to work with around here.
That soil is not the native material. This whole site was filled in with structural fill. 5' to 8' in some places. Around 8,000 tons of it and another 2000 tons of item #4 for asphalt sub base. What you see in that photo is the fill material.
I never got off of the dozer for weeks, the roller never stopped and the trucks just kept coming in, getting stuck, being pulled out all to do it again on the next load. The compaction testers were a royal pain, material to dry, to wet, lifts an 1" to thick, you get the picture.
The footings on the back side were just about at existing elevation with a 10' back wall, the whole inside of the building had to brought up that much.
The top soil we stripped, stock piled and reused at the end. I was lucky to have enough so didn't have to buy any, just move it around (twice).
This site also included water line, septic system, light pole bases (huge ones), electrical trenches, all concrete prep, asphalt prep, and lots of compaction tests.
