Overheard a senior drafter say "accuracy over speed" and it hit different

Guy in his 60s said he's seen CAD guys rush and miss by 1/8" on a foundation plan. That one inch mistake cost a crew 3 days on site. Any of you ever catch a big error from rushing?

Man... buddy of mine had to re-stake an entire foundation off by that much.

Come on, a half inch is nothing. On a slab that size you're gonna have settling and shifting anyway, concrete cures and moves over time. Your buddy's foundation was probably fine the way it was, re-staking the whole thing sounds like overkill to me. I've seen guys pour footings that were off by an inch or more and nobody ever noticed once the forms were up and the concrete was down. Half an inch is within the margin of error for most residential work, builder grade stuff isn't a NASA rocket. Unless he was dealing with some crazy engineered spec or a commercial job with tight inspection, that re-stake was a waste of time and labor. Better to just adjust the forms a little and keep going, you're not building the Taj Mahal.
