Subject: Re: [TX/RX Labs] Re: The walls that are being built

Some of us had discussed this whole problem vis-a-vis the electrical wiring.  We decided on surface conduit for several reasons:
 
1. We can't use Romex because the walls aren't continuous.
 
2. Surface mount lets us do a phased installation - we only have to pay for the essential areas now and we can build out as we have time and money.  Also, we can add on later in a consistent way if we add equipment that requires special service.
 
3. It is an appropriate artistic choice that fits the "geek chic" aesthetic of the lab.  Think Pompidou center.
 
Especially for the latter reason, I suggest using surface mount wiring duct for the data lines.  Artistically,  if you're going to break the rules, break them big and intentionally.  So instead of hiding the wires in the walls, embrace the look of exposed conduit.  Better yet, paint the conduit bright primary colors so everyone understands that it's a choice, not a compromise.
 
Also, we're still up against the lack of contiguous walls.  Yes, you can run LV wiring without conduit but if you run it in an "environmental air space", i.e. not inside the wall, you have to use plenum-rated cable which is more expensive.
 
I've used this duct/raceway in the past and I thought it looked fine. The PN05 size will carry 5 ea CAT5 or 3 CAT6.  It comes with a PSA backing and you can get all kinds of elbows, tees, outlet boxes, etc for it.
