   A mechanical contractor that I worked for often referred to CAD as a savings of 20% of the total labor hours.

I took this to mean that CAD coordination eliminated 20% of the labor hours that would have been incurred without CAD, and that some smaller figure was substituted in since CAD has to be done.

For instance, if you added 5% back in for CAD, your CAD operators save your company a net 15% of total labor hours, definitely making it worth paying for.

This doesn't sound right to some others I've spoken to. Does anyone have any rough figures that they're familiar with? Does this percentage sound high? I teach a union CAD class and would like some accurate (as far as averages go) figures to throw at to-be CAD guys.
