In my experience, jobs such as this that go in the general direction of 'design/build' tend to be a way for the Owner to shift the blame to someone else if something is done wrong.
I would expect that someone with "more skin in the game" tell me what this pump is. Then I can get it installed per the proper Codes with no further direction from them.
I don't want to treat it as a standard motor and get nailed a few years down the road when the building burns down with some hotshot saying that it was MY fault because it didn't wire it per NEC 495...or go full boat and get unpaid when I send a bill because I went overboard when all that they wanted was a plain motor installation.
This could get pretty sticky either way.
