>Do you really think this is what happens on job sites? Does this match your personal experience?
I worked in ICI (Industrial, Commercial, Institutional) construction for ~10 years. Yes, this matches my experience. Perhaps it is different where you are from.
I also experienced this while doing utility locating for oil & gas pipelines (~2 years). As-built drawings were very accurate, and detailed any deviation from the initial drawings.
In the 2000s I had a SaaS firm making software for underground utility locating companies so I learned a lot about the industry. In most parts of the country as built drawings are unusual for residential property anyway. Locating staff mostly shows up, looks at whatever drawings are available, and then has to figure out what was actually done from the clues and by using locating equipment. Many of these folks end up with a very subtle understanding of what common practice was by different utility companies in various specific areas in specific eras.

I was doing large transmission pipelines (i.e. NPS 24 to NPS 56), so I can't speak to residential, but I wouldn't be surprised if there was less attention paid to as-built drawings when the cost of damage/replacement wasn't in the millions of dollars.
