brick veneer support at sides of dormers
(OP)
I have been searching through the BIA Technical Notes for a recommended detail for supporting brick veneer on the sides of a dormer...is there a preferred way? (see attached image)
Thanks

If the bricks have holes, short lengths of field welded vertical rebar would suffice in lieu of the tabs.
Proper flashing would be imperitive to prevent leaks here - an obvious placed to develop.
The rafters under the wall should be designed to L/600 minimum.

Detailing for the inevitable moisture penetration behind the brick veneer is critical.
RE: brick veneer support at sides of dormers
I was hoping I could put thin brick adhered to durock on the sides, but the brick I am using doesn't come in thin brick. Also, the sidewalls aren't going down to the floor so I can't support from the floor. It's not that much brick so I think my two solutions are either Mike McCann's suggestion of the angle with welded steel plates bolted to the stud or...convince the owner that he really doesn't need to see brick on the side of his dormers http://www.tipmaster.com/images/bigsmile.gif

Either the angled steel member with tabs or going down to a satisfactory horizontal member to build off of are common solutions depending on the conditions, and details necessary.
The key is proper flashing to prevent water penetration.

When the brick veneer/concrete block extends down to a beam in the floor system, there is no need for the wood framed wall to continue down. The unsupported height of the block below roof level would max out at like 4 ft or so.
RE: brick veneer support at sides of dormers
If you look at the perspective posted by henryd, it is obvious that the dormers are roof projections only. Nothing extends below the ceiling.

I never liked building the dormer on top of the rafters. 9 times out of 10, there is a knee wall inside anyway, so building them on top was really of no benefit as far as space goes.
I'm with Hokie on his original post, I wouldn't even consider brick here. The last few houses I built like that, I convinced the owner to use Dryvit, lick'em stick'em stones or a high-end siding. There is just too much movement up there.

But, we have used 4x4x3/16 painted steel angle (w no tabs) for cases like this. Lag every stud, solid blocking 2x8 on edge beween studs, 16x16 bent edge Galv flashing over 36" peel and seal underlayment. Enshure the truss at each dormer edge is designed for the DL or triple the trim rafter.

...just sayin'.

I see this all the time. Architect wants a brick chimney sticking out the roof, but if you go to the inside of the building, there is no fireplace. The chimney is on a pretty steep slope. Now, do you want to keep telling your architec clients that you cant do that? How are you going to get their business again?

RE: brick veneer support at sides of dormers
I agree, I was merely suggesting that he at least suggest what might be a more feasible solution. If it is bricks he wants, well, bricks he shall have....and cracks.

Hey that's me!...I'm an Architect, but I have always considered a good engineer and builder to be my best friends.

1. Chose another finish other than brick for the sides of the dormers. (Still keeping the face of the dormer in brick)
2. Go with the custom sloping steel brick angle with lagged to the dormer studs which are carried by the roof rafter at a very stiff L/600 or better.
3. Thin-Brick "Lick 'n Stick". I realize that you said it is not available, but have you considered the possibility of having thin brick made for your application? It may be possible to have the mason slice the faces off the full brick to create your own custom thin-brick...labor intensive, but might workout to be similar in intensity to the custom steel lintel design.

I think they are a lot lighter.

I have done it myself a hundred times.
There is nothing difficult about it.
RE: brick veneer support at sides of dormers
The longer vertical leg allows more than one lag bolt at each stud which may be necessary to support the load.
I generally don't specify bolts larger than 3/8" diameter in the 2" face of a 2x4.
Also pilot holes should be specified to prevent splitting the wood.

My suggestion would be to use one single "fin" at the bottom and then use a spacer of some sort in the mortar joints the rest of the way up the hill until you have a level row of brick. Similar to tiling a tub surround. The spacers will wind up buried in the mortar joints.
