From your description, this sounds like a commercial building.

If this is the case, this work should be done by a licensed EC.

Gee, the specs may want 6 hots, 6 neuts and six grounds????
I may doit that way; other guys may do it differently.
BTW:
The majority of the members at this site post info on themselves; you failed to do that. Any Reason??
