I trust you saw the post of FM class handouts pinned to the top of this forum? Hopefully newer stuff will be uploaded soon, too. But, the basic principles are the same. And the BIM & FM page on the Facilities Management Community area?

My last facility was very complex and very old. The paper to CAD transition took about 15 years, and the CAD to BIM transition should take about the same amount of time. Obviously, most facilities don't have the funds available to have that type of thing done on a mass basis, so it was pretty much covered by renovation projects only (you have to really ride your project managers, architects, engineers and gcs about CAD or BIM standards to ensure you're getting decent editable electronic documentation, which is a whole topic unto itself). I know it's frustrating to move that slowly, the engineering analysis which will be a big benefit later on, can't really be done when you've only got 15% of your building modeled.
The architectural modeling seemed to go pretty quick. They were starting a campus upgrade as I left, and the architectural firms managed to do pretty decent models of the 5 most affected buildings in pretty short order. The MEPFP is a whole other animal, though. They didn't model much of that up front, it would've been cost prohibitive.
Now, I believe Clyne Curtis out at Brigham Young University used student labor from the architectural programs to have his campus modeled.
If you could pair up with some instructors from a local university or trade school that wanted their students to get some hands on surveying and modeling experience, that could be a way to make it more affordable, or if your company is supportive of interns, etc.
