We didn't win the bid so it's a moot point, probably a good thing.
It was an unusual situation and I was wondering what others have done.
In Nebraska the AHJ does not do plan review for electrical.
The engineer answers to no one except the architect who hired him. All code compliance issues fall back on the contractor. In fact the engineer and architect will put in their contract that they are not responsible for errors and omissions.....I wish I could work that way.
The gear was bid by both Sq.D and Siemens. Sq.D provided a field service tech to install the main. Siemens provided just a breaker. There was about a $30k difference.
