Compliance is part of the general terms and conditions. An architect or engineer also isn't going to tell you how to comply with the NEC, just to follow it. What I'm looking for is not design information, you are correct that that is supplied by the architect and engineer. From what I remember, in an operating hospital there are requirements for isolating the work area from the rest of the building, providing negative pressure ventilation, entrances and egress like you would use for asbestos and lead remediation. And I'm sure it gets even more complicated because of the spread of infectious diseases.

If you are bidding a project, I would expect the drawings and specs to say what is expected because requirements normally vary a lot depending on which part of a hospital the work is in.
But in general, I would expect basically what you mentioned. Dust barriers, negative pressure, walk off matts, frequent cleaning, filters on return ducts, wet cutting when possible. More sensitive areas may require HEPA air cleaners, requirements to wear paper overalls and clean outter clothes through sensitive areas, and anti-rooms at the dust barriers for putting on paper overalls, shoe covers, and hair nets.
Infectious diseases shouldn't be an issue - you shouldn't be in any areas that have infectious patients. Hospital staff should be doing any disinfecting and pre-cleaning and final cleaning.
Sometimes in OR's you need an air testing agency to come in before and after the work. The room has to be cleaner after you leave than before you started.
