It must just be one of those weeks, but every set of prints I pick up seems to have been engineered by someone who has lived on another planet. Like a '10' KVA 3 ph xfmr to feed a 125 A panel, or (20) 1-1/4 spare conduits to a panel that has only 8 spare ckts, and a (60) pole contactor to for the same 30 ckt panel.
Tell me your story - make me feel better - it FRIDAY!
(by the way, I do know it's hard to get everything right when engineering a job - BUT REALLY)
4” GRC conduit for all data drop in walls for a single CAT-5 (remodel of public building) 75KVA transformer (copper) for a 1,500 sf retail lease space (clothes store) No MC or Flex allowed, even for fixture whips (large box retail) Voltage drop must be maintained at 1% or better. (large box retail) Architect specified "plumbing 90s" for all exposed electrical conduit.
How about being given the wiring diagram for a small quarry on the back of a cigarette packet by the boss then being told "Oh heck you know more about panel wiring than I do. What ever you do will be right just go there and tell me what you need" This after being interviewed in the morning in the workshop rest of that day. At the quarry next
YOU GET PLANS???!?!?! Lucky!! Last renovation job I worked at did not really have plans. Er, well it did but the interior designer made an attempt at doing the electrical "comics" as we called them. Enough said there I think! I swear a 4 year old with a box of crayons could have done better!

This reminds me of a church remodel about 13 years ago.. I was working for the campus radio station as an engineer at the time. We needed to be able to run a 6 pair 22awg PIC telephone cable from the steam tunnels behind the building, into the basement A/V room. We asked for a single 3/4 or 1" conduit, and got a pair of 4".. talk about overkill..
