Hi, been following the forum for a while, but never posting. I work as a consultant designing audio-video systems and we draw all the associated conduit / box for bid documents (generally new construction, all commercial work for spaces like auditoriums, hotels, broadcast studios, etc.). We'll size all AV conduit directly on our drawings to simplify take-offs for EC's bidding the job. I've run across advice a few times that conduit prices larger than 2" rise quickly, and that I'm generally better off running multiple 2" conduits vs. a single larger conduit like 3" or 4".
From what I've read, this is mostly due to project specs commonly requiring rigid conduit instead of EMT for anything larger than 2", and that those larger conduits require 2 guys to mount each pipe instead of 1. Going from a lot of hear-say though, so was curious to hear from the guys here if that's actually accurate.
In many cases, multiple 2" conduits vs. 1, 4" won't make a difference for AV wiring, but I was curious how it impacts the EC's time and cost.
