quote; Thank you I will be revising and re-submitting in the near future as I am at that point of the renovation.
Actually, that is the key to the whole project. You make a drawing and submit it to the building department. They reject it and you revise it and resubmit it. This process repeats until they are satisfied with the DRAWING. Then you, or a qualified plumber, installs it. Finally an inspector looks at the installation and determines whether it was done like the approved drawing. If so, he approves it, if not it is rejected and has to be redone.
Here is an example of when the process goes awry;
Several years ago I was installing the plumbing for bakery departments in grocery stores. All of the installations were basically similar. About the fourth one, when I took the isometric to the building department, they said I could NOT install the system that way, regardless of how it had been done previously. When I asked, "How can I install it then?", they said to take it over to "Joe" at the adjacent desk. Joe then proceeded to revise my drawing. When he finished he had "true" flat vents on all the floor drain lines. When I protested, "You cannot do that", he said, "Yes you can under the new code". Since the revisions were simple to incorporate into the piping we had already installed, I told him, "okay, send the inspector out this afternoon". When the inspector arrived he took one look at the installation and rejected it because of flat vents, but then I showed him the approved drawing. He looked at it, then at the installation, and asked, "Where is the telephone?" He called his senior inspector and told him, "These guys have an installation with flat vents and a drawing approved this morning showing them. What should I do?" The boss told him, "Have the person who approved the drawing, make the inspection and approve it." I told the inspector that as soon as he left, concrete was going into the trenches, regardless of whether he approved it or not. He did, but 30 minutes later he came back and said, "As of this minute, we are back on the old code". Six months later on another job, he said, "Aren't you the same guys who did the grocery store bakery? Can you redraw the isometric for the installation, because ALL of the paperwork for that job has disappeared."
