I'm moving on into a project bigger than the remodeling, small projects i'm used to. Building the dream garage. (dreaming I'll be done on budget)
Engineered plans for a 2 story gambrel garage call for a double 2x6 plate on top of the stem wall. One, I'll assume is the mudsill and to be p/t, but why is the second sillplate 2x6? the wall is 2x4 framing.
The foundation crew used tie down bolts, not straps, so I'm sweating the bolt height too. I'm thinking of keeping the second 2x6, but notching/drilling wide to clear bolts and nuts(and cutting the bolts down flush with the second plate.) then frame the walls using traditional 2x4 plate, tilting up the wall, nail down to the double mud sill. But that'll make total of three sill plates. Seems easier, not trying to lift a wall into place over the bolts, but strikes me as stupid to have 3 plates. simple and stupid--all at the same time.
expert opinions welcomed!
