Walked a job site in Phoenix and the expansion joints were a total joke

I was out in Phoenix last Tuesday looking at a parking structure for a friend and the expansion joints were spaced every 40 feet. In the desert. With 100 degree temp swings. Someone quoted that slab out with zero thought to movement. I counted 12 cracks in one bay alone. The guy who poured it probably saved 2 hours of work by skipping the extra joints. Now the owner is looking at a 15k repair bill. How do you handle telling a GC their spacing is wrong when they already signed off on it? Has anyone else dealt with this on commercial work?

Ran into the same thing on a tilt-up in Vegas. Pulled up ACI 360 spacing charts and the local code on my laptop right there in the trailer, then showed the GC the crack map next to his joint layout. Framed it as a change order risk on his end, not a blame thing, and he got it. Got the extra joints cut in before the slab took on any more damage.
