Conduit for balcony floor

[wxstevens]

I am putting in a couple of light circuits at a church building. While I am there, they ask me if I would move some audio/video cabling which will require about ten feet of conduit. It would have to go in the floor of the balcony and it is cantilevered (2X10 joists). Because the A/V cable ends are factory made & I don't want to cut them, so I need to put a fairly good size conduit in. Where can I find the allowable size to notch the floor for the conduit without hurting the structure? Also, do you know of any problems using PVC for the A/V? Thanks.

Have you ever seen the plumber cut the entire plate out? You can cut the plate and install rigid metal braces to hold them together but quite frankly I am not sure you need to on the bottom plate. I have cut holes for 2" PVC in a 2x4 wall and never had a problem.

Don't have an answer for you, but the OP appears to be asking about a joist.

I believe that Dennis's comment is in regards to a top and bottom plate of a wall. BIG differance.

A church balcony will have live loading, and I would not make any changes in the structure without an engineer approval, PVC in a place of assembly? I don't think so.

Why does it even need to be in conduit at all? If it is underneath it is not going to be damaged.

I agree that cutting into a structure like that requires some expertise into just what can be done.

I don't see why PVC would be a problem if it's being used for audio equipment, am I wrong?

And even scarier - its cantilevered, so I'd definitely wouldn't be touching that.

Time to call the engineering professionals.

Or hack the end off the cables and remake them...
