The ME wants the Area and Slope increases per 11.2.3.2.4 and 11.2.3.2.5. I pointed out the listing of the Attic heads but all he says is " If it's OK with the Local AHJ, he takes " no exception to that design approach" but he will not stamp the drawings saying this, even tho he DID stamp the first set " rejected/ resubmit"! LOcal AHJ requires plans to be stamped by the EOR or the Architect prior to submission, and the Architect won't stamp them " because". Trying to build a case that what we did is " per NFPA 13 and industry standard. Any thoughts?
