I recommend googling "U of M UDA Phase 3", there should be a PDF as the top result which has the most information about the SEMI District and the ADM-Delmar Elevators. This was where I got pretty much all the main information.
Nice start on the History of United Crushers. I'm a little surprised you didn't contact the owner. I would be happy to work with you to create a more complete and accurate video. With your permission, we might link it to our web site, if you are willing to update it. Call/email me.
