Inside wall conduit codes?

[baspinall]

Hope this where I should ask this. We are cabling(voice and data)a small building and need to run 4" conduits between floors within the outside walls. They do not want cores in the floors.
2-questions. Does code allow 4" plastic pipe to be ran within walls (actulally we want to use the lighter 4" drainpipe in 10'legnths)?
Next, the drywall in this building runs up to the cielings on the outside walls which leads me to think they are fire rated. Can I cut out, say 2x2 sections of the drywall to access the conduits and run the cabling through then, fire stop around the conduits leaving them accessable for cabling in the future?
Thank you for any information.
Brian

Brian put the 'drain pipe' idea right out of your head.

800.48 Raceways for Communications Wires and Cables.

Where communications wire and cables are installed in a raceway, the raceway shall be either of a type permitted in Chapter 3 and installed in accordance with Chapter 3 or a listed nonmetallic raceway complying with 800.51(J), (K), or (L), as applicable, and installed in accordance with 362.24 through 362.56, where the requirements applicable to electrical nonmetallic tubing apply.

Exception: Conduit fill restrictions shall not apply.

If you put it in 'pipe' it must be pipe for electrical use.
