We went through this when subcontractors wanted to have engineering drawings done in far-flung places to save money.
We got the drawings in for Farmersville Highschool (in California) and they were done in Puerto Rico by someone who studied in metricland.
They submitted drawings with dimensions like 5/12" and 3'-17"
Dang They submitted that? Lol
We have issues with dimension overrides and if a column line doesn't fit they just leave it off. I was field checking and was short 120' of pipe. I started looking and they modified dims then left of 2 steel column bays.
I told the main company I'm not sending another thing to Mexico. Well the head honcho came down and told me I would then explained that it was to keep us competitive. I later looked at the bid they submitted normal pricing then took advantage of cheap labor. Which isn't cheap considering we have to redo everything.
