Re: Well that was an invisible problem
"we won't pay for cabling that new floor we've expanded into, we'll use wireless as it'll be cheaper"
Ah yes. I’ve had that (only once though). One director thought he could cut costs by skipping cabling, and signed off on everything without consulting anyone. Once the builders were finished, the new office looked amazing. Polished concrete floors, beatiful furniture. It was of little use though, since he skipped *all* cabling. So no power either. For on office area destined for mainly desktop users.
AC because I still work there, and so does the other guy. In his defense : he didn’t make the same mistake twice, next office expansion included raised floors for an 800 sqm area.
