CAD-Based Photogrammetry

This is most probably the solution to the "as-built problem".

Not having had direct experience with this yet, I'd guess that it is expensive. Of course, "expensive" is relative; how much does a two-person team with a tape measure/Disto cost for a one-week site stay cost?

With 8 megapixel cameras becoming more affordable, this could have a big impact on smaller and mid-sized piping facilities that plan on upgrading.
