Overheard a union rep say 'don't trust any level that was checked with a string line'

I was on a callback at a 12-story office tower in Portland yesterday and heard that comment in the machine room, and it got me thinking about how often I still see guys rely on a string for rail alignment instead of a laser. Has anyone else noticed a shift away from string lines in new installs, or is that just my crew?

Read somewhere that lasers are way more consistent on long runs, especially with thermal expansion messing with string tension. Saw a stat that claims lasers cut callback rates by like 40% on high rise work. Makes sense that old school string guys would be skeptical though, hard to break habits.

Blame the tool when the real problem is nobody knows how to plumb a damn wall level anymore.
