I have 8 20amp I.G. circuits using #10awg in one conduit from the panel to a pull box. From the pull box we ran 12/2 I.G. mc cable to each of the 8 dedicated outlet locations. I used the approved grounding method of pulling only one ground through the conduit and tying all 8 ground wires to the one ground wire in the conduit at the pull box. Can I do the same with the I.G. (grenn w/ yellow stripe) as I did with the ground wire (green)? My PM is telling me that each dedicated circuits I.G. needs to travel through to the panel. This seems a little redundant carrying 8 I.G's through the same conduit not to mention fill factor. If my PM is correct where is this referenced in the code book. I've looked and can't find anything. Thanks.

Not really in the code book, it a design decision and may be in the job specifications.

:D thanks I will check the job specs again. Didn't see anything when I first read them. Will dig deeper into the fine print. I wonder if an RFI to the engineer would be a good move?
 
As stated, not a Code issue but rather one of design. It is commonplace in design specifications to require an IG-EGC for each circuit between source panel and its outlets.
