I need to interface with the electricians, carpenters, HVAC, and the GC on every project. None of them have the same drawings and none of their versions are the latest from the architects and engineers. The architects or engineers are also very expensive, so they rarely get brought back in for updates to drawings once unless it has to do with code / regulatory approvals. This ends up with the client's latest real drawings being a jpeg screenshot of the original plans that they just email blasted to everyone.

All the vendors and boots on the ground definitely have a version of the CAD floorplans, but it was whatever they decided to print out 3 weeks ago when they got this job on their calendar. The workers have just been marking it up by hand since then. This is where a lot for the confusion, delays, and change orders come from. I don't know if this is just what to expect with budgets less than a few million, or maybe it's just retail style projects, or maybe my clients attract poor quality vendors (I guess that says more about me). The only time with no major problem was when one client stuck to one GC over the course of 20 new buildouts. They eventually figured out how to wrangle all their subs together.
