True, but if you have an auto feed screw gun and you deduct for all of the nails that missed the framing (nail gun cowboys), it's probably close to a wash.
Cutting a let-in brace should take, what?, ten minutes if you're loafing. I can't see how the difference between one type of bracing and the other would have any real impact on the budget.

You said the owner wanted to "would over build", wanted to exceed any & all codes.
but............
interior/exterior wood sheating. In addition, it's faster, and less expensive, (material/labor) to build the walls on a slab and fasten diagonal shear metal banding (interior/exterior?) with screws then to cut/ install diagonal 2x6 shear bracing into the walls. >>Everything will meet or exceed any codes.
R- Keep the cowboys away from the nail guns & just tighten up on the nailing schedule slightly, don't worry about the few misses, nobody fixes them......btw don't all shearwalls get nailed at about 4" independent of what the dwg says; 3, 4 or 6? :)

Not if I'm around. Even a few misses compromises the strength, although I don't worry about the odd miss here and there. It's the row of missed nails that pisses me off.

Yeah, a row of misses is bad, even if is it only field nailing...turns out that for cyclic loading, one of the possible failure modes is "out of plane" sheet buckling.
This is esp a problem with thin sheathing, even a few missed field nails (since they're only 12" oc) w/ 3/8 ply will allow the sheet to buckle. This buckling action actually pulls the boundary nails (that's why those wimpy .113 nails aren't so good) & compromises the overall strength. This doesn't seem happen with 1/2 (15/32) plywood. The field nails closest to the sheet corners are the most important.
That's why, I really don't like 3/8 but the code drives shea rwalls to
3/8 since it gives your best plf per $. Additionally field nailing should be more like 8 o/c not 12"Slight over nailing allows for occasional miss
btw never used a screw gun w/ auto feed.....don't the cowboys miss with those as well?

Tear along the perforations, and mail in for your liability settlement.
Now that's a STRONG POSSIBILITY!
Irrespective of all the suggetsions & controversy, I do know this guy will eventually do everything right. I also know he'll wind up overbuilding. He's engaged in the Nuclear industry where safety factors (4:1 minimum) run way past what the world lives by...............
Dan
Yeah, he'll wind up overbuilding from HIS point of view......... I really don't care if he's from the nuke industry....this ain't the nuke industry, he has his own set of experience but it doesn't have much to do with timber framing.
Exactly, or if you want to do something exotic, get qualified people to do it for you.
It seems like 75% of the posts here are, "I want to do something everyone tells me I shouldn't, but is cheaper and probably illegal. Can one of you internet experts tell me it's OK, so I can go ahead and do what I'm going to do anyway?"
Sure, but there's more feedback driving screws than shooting nails so they're more likely to discover their error and compensate.
