- Depth checked in several places, not just the corners
- Reinforcement placed and supported off the ground
- Truck access confirmed, and somewhere to wash out

- Screed, float, edger and gloves on site
- Weather checked, not pouring into frost or heavy rain
Measure the depth in several places
A sub-base that dips half an inch across a 10 by 10 slab is about 4.2 extra cubic feet of concrete, roughly an eighth of a 4-inch pour. Corners tell you almost nothing. Check the middle, and check it again after you have walked on it.
