If you have experienced delays in detailing and procuring steel, it may be because the design documents were difficult for the fabrication detailer to interpret. Or multiple changes issued after the detailing process began may have made it difficult for the draftsperson to keep up. Or the specified steel sections were unavailable from warehouse suppliers and too unusual for the mill to fabricate quickly.

Professional golfers like to say that "they drive for show, and they putt for dough." Similarly, some would say that for most architects, rendering packages are for show and CAD drafting is for dough. But that statement is far less true today than it was five years ago, and certainly far less true than ten years ago.
