(OP)
We have been asked to survey a 12 story hospital to develop plans for replacement of all horizontal DWV pipe in the building. What typical things would/should a plumbing engineer be looking for on a survey of this type?
Thanks...

Given the conditions above the ceiling (with duct obstructions, conduit, etc), should the slope problems have been picked up on the original engineering survey? Keep in mind the original scope was just to replace the failing pipe.

I would look for places where the pipe has or is failing. Look at ceiling tiles to see if there is evidence of leaks. Look at the elbows at the ends of the drops for erosion damage. Look for longitudinal cracks in long runs. Look for where piping is bowed (if it is plastic). Look for places where dissimilar metallic pipe materials have been joined (CI vs galvanized vs copper).
All this can be a long and daunting task. The first place I would look is the maintenance office. These guys, especially the ones who have been around a long time, have first hand knowledge of where failures and problems have occured and can give good info on where future problems might occur.
Try these as a start.
