In commercial installs, (multi-story high rises) I used two 4" sleeves
(three sleeves on some of the lower floors) between wiring closets on the
floors.

I'd bet few of those had any 1 inch hardline running around

I keep the RG-6 coax runs in separate conduit from the UTP runs.

Hmm.. Why? Shouldn't be any effect either way.

Reduces problems (you never know who will follow you) with pulling future
RG-6 cables. Also the bend radius tolerances are different. IF UTP cables
are within same pathway the pulling crew has to be more gentle and careful.

Now if you have ever worked a large cabling installation ... you know that
words "gentle" and "careful" are a foreign language terms to many cabling
pulling crews.
Although when I have traveled with these crews .. they referred to the
airline baggage handlers (pre-9/11) as gorillas (former TV ad of a logistics
company).
