Got a whole bunch more done on the pad, ⅓ of it is within 2cm which is killa, another ⅓ is within 5cm and the other third is about 10cm low. It is level side to side, it's the length of it that drops. Not bad for an eye ball job but needs some work. Tomorrow, I'll use my mower to pull a dyno ramp to more evenly distribute the base, so it is within the 3cm required.
It's the same size as the shed in the background, but has a personnel door where their roller door is and has 3 roller doors along the width.
I'll fix the fence when it falls down
Here's a few pics of the progress
