Thank You.
I am the acting as the GC on this project and have learned much from this site and do appreciate it. It was quite interesting to see the response from the different ec's bidding the job to the questions I was able to pose in the job specs, much grabbed from the violation forum.For instance, the Ec I went with was one of only two that would agree to not backstabing. The EC will definately do it, he just had never seen the compressed air lines done in other than pvc if done at all he is strictly residential.
