Someone I used to work with (we'll call him Tim) told me a story a short time back. He was doing a big commercial job and talked with the electrical inspector about using aluminum wire instead of copper. The inspector said ok.
So later on that day the superintendant came out to the jobsite and Tim informed the superintendant of the conversation he had with the electrical inspector. The superintendant was thrilled due to the cost of copper at the time. So the superintendant told Tim to go ahead and resize the conduit and wire.
What's the electrical inspector got to do with materials used on a job. All he can say is that Al. is legal for use on this job.
If the job specs. call for copper wire then you would need more authorization than an electrical inspector and a job super to change out the cable.
What was the customer paying for on plans and specs. submitted? A large commercial project is going to have engineered plans. You don't get to change these because you find a cheaper way of doing things.
Most jobs will require you to go all the way back to the engineering stage to get authorization to make changes like this. If they wanted the job engineered by any Joe Blow on the job they would have paid for plans to start with.
