Agreed. If it was a public works project, they probably took the cheapest route. I thought the surface was clay tile. They definitely wouldn’t spend time trowelling.
The worrying thing about the fault is that it’s probably even bigger somewhere below.

My Asian experience is different. I’ve seen the absolute worst formed concrete and concrete block work imagineable parged over and troweled smooth. I’ve seen many examples where they recreated the morter joints with tools in the freshly applied stucco to make it look like the concrete block construction they parged over.
