Two inches
On a building under construction, the entry slab sat about two inches above the public sidewalk, with the storefront framing already going in. There was no room to slope a public sidewalk up to the door, so the storefront had to move back and the entrance was redesigned and rebuilt on the project’s own property. Check it on paper, not after the pour.

The column move
Early in my career, the structural engineer moved a column and I missed the change; once the steel went up, it sat partly in the exit stair door opening, and the correction cost time and money nobody had planned to spend. My production manager then had me overlaying structural and MEP sheets on our drawings at a light table. I still treat every drawing as an unverified claim.
