Occasionally we have worked for the contractor instead of the Owner. Lots can go wrong in this arrangement, but with the right firm it can also work well - for everyone.
One of the things that might be different working for a contractor is that they may have specific requests for how they want information shown. We rarely use a sheet size other than 36x24. This determines the placement of a lot of information. Considerations like this ignore the user of the drawings.
One of my favorite contractors is the third generation in his family's business, usually a bad omen; but he is more hands-on than almost anyone I've come in contact with. For an office addition for his (our) industrial client he had a very clear idea of how he wanted our work laid out on the drawing sheets. See the image.
His instructions were: "Get both floor plan and ceiling plan on the same sheet along with door and finish schedules so everything is together and I don't have to flip back and forth when I'm working with my subs."
As you can see, it worked out very well. Although, compliance with the National CAD Standards was shot all to hell!
