Imagine saying this! "And, for this next change order...." At $50, plus mark-up! Then imagine yourself in court, deffending this item!
Or, "And, for this next change order, we suggest an isolated feeder for the A/V Panel, and 50 Amp True-sine isolation UPS. And, due to connectivity problems, we'll have to have all of your equipment re-listed for hard wiring. This way we can eliminate recepticals all together. You'll really hear the differance!"
