It is possible to have this weld eliminated, as I did on my 42″ project, if the contractor can get the engineering clearance. I’ve worked 5 large bore waterlines as a rig welder, one 42″ short line I contracted myself, so I have some experience but there are others who cc206 in that niche and can speak more authoritavely than myself.
That pretty much answered my question and my curiosity. If you have D1.
Anyone know the AWWA c code ?
Water work is generally IMHO far less critically challenging, but every application in this trade has its tricks, short cuts and learning curve and I thought I might pass on the few crumbs I’ve gleaned from my limited time in those particular trenches.
Generically speaking, my experience with AWWA is that it doesn’t have a lot of teeth. The best welders on that line welded that joint in a 10 hour day and inspection was stringent.

Not logged in American Welding Society Forum. Welding the inside lap joint on a 36″ line would not be a job I would care to volunteer for, at least not for an extended period of time- it gets a little cramped in there for me. Something to chew over maybe anyway.
Having read postings from you in the past, it appears you tend to focus and specialize more in the gas and energy business than large bore waterlines. It required the voltage module to be installed on my Classic D, which I wasnt going to spend for, so he by passed the code wth charpy testing on my weld test and I was good to go.
