It sounds like a good challenge Travis, and congratulations for getting the contract-- the self employed designer who turns down any work has never lacked for beer and cigarette money. And typical of goverment work, there are the doers vs the reviewers, and every which way the doers turn they are screwed by an inch or two. When the Corp of Eng is the AHJ though I have had good luck with the field people- they seem to know when you have gotten as close to the intent as reality allows-- ie, instead of deflector distance they look at 'bulb' distance- within an inch or two, and rightly so.
We NICET IVs who can design, calc, bim coordinate, and stocklist are often the saviours of projects that would otherwise be a total cluster without us.
