[Cob] finding statsclaysandstraw kindra at claysandstraw.com

Sara- your first clue: when looking for cob stats use the word "adobe". My favorite structural engineer in Santa Fe considers them identical... he did admit that monolithic adobe could be stronger than assembled blocks. I have found that using load and shear calculations from adobe blocks gives you whatever you need. For working with your township: give them a printed version of the NM adobe code (check Questin Wilson's page- he has a downloadable PDF of the code there). Inspectors like to know that they would not be the first to approve a mud structure. So as a personal anecdote: after taking two years off to study natural building including an apprenticeship and various workshops, I STILL learned things from the NM earthen building code that no one had mentioned to me before... 1. structurally, bond beams are worth it 2. the distance that headers bear on walls beyond the window opening is quite crucial 3. stem walls should rise above interior floors (not to say everything in that code is perfect, for example... they still allow portland in plasters over non-stabilized mud walls - but at least they don't force you to put it in) By the way. The NM building code is a state adopted amendment to the International Building Code advocated for and put in by the people of the state. Yeah, the people who cared about it got up and wrote their own law, go figure.
