It's not really clear whether you are asking for help with the CAD drawing, or the installation method. For motorized you would use the same hardware installation as you would for a large commercial sliding gate opener, with tracks, pulleys, motor, etc. The hardware would be available through gate opener manufacturers/distributers. The plan may have to be engineered by an architect due to load stress. Once the engineering was figured out, and the hardware selected, your architect/builder would create the appropriate housing.
