For those wanting to watch a master class from Bill East on COBie then I would highly recommend the youtube videos below. There is a series of five videos that are linked from the first one.
And a few screeengrabs from it:
Screengrab 1 - The digital model sure looks pretty!
Screengrab 2 - But where is the information about the valves and pipes?
Screengrab 3 - And the entire HVAC system is in a single room the size of the building!
Screengrab 4 - how do we turn all of this paper into rich digital information?
