Sweet.. gotta admit I don't often see the builder as the PM. Maybe the construction manager come that time. But a true PM sees a job from concept to completion. Builders come in around 80-90% through detailed design. Oversee the end of the design which gives them familiarity with the job, then build the thing. Basically appearing like they take over but the PM or client rep is still running around in the background (this is what I do). Someone has to keep the builder honest. Shadowing is brilliant. That's great. If you are happy with your decision (obviously not made overnight) stick with it. To put it this way: builder knows he's gotta put a copper pipe on the wall and that he'll be delayed by 3 days if the pipe order doesn't turn up. Project Manager knows why that pipe goes on that wall, which hydraulic service it is for, what pressure it contains, how it interacts with every other pipe on the f*cking site. Real project managers need to understand basic electrical, hydraulics, access and mobility standards, access and egress requirements and we'll everything else going on the site so he knows that his client isn't being ripped off or paying for something 6 times the size it needs to be.
