Feeder plans

[Charged]

What are overall thoughts about conduit routing/ feeder plans in a set of drawings for a typical commercial building?. Basically reflecting all the feeders on the single line in plan.

Personally I don’t like to do it. I think the contractor is free to do it as he wishes meeting specifications and NEC. I think there’s a lot that goes into it with scheduling and don’t see why I need to try to direct it. I should be thinking it through during design , to make sure it’s possible from point A to point B and to upsize for any voltage drop concerns but in general I do not include these plans but others in my office do.

I am inclined to agree with you, at least in principle. However, there are probably some cases, such as where you have to account for seismic constraints where you might need to show the routing because someone will have to make the appropriate designs for the wall penetrations.

We use both a single line vertical riser drawings and a conduit drawings. The conduit drawing is typically coordinated amongst all of the mechanical contractors so that the conduit runs don't conflict with duct work, sprinkler lines, plumbing pipes, etc.
