BDCS - NCARB Ramp, Stair, Roof Vignettes (Comment Please!)

[marge]

I took BDCS two months ago and didn't pass the ramp and the roof vignettes. I don't know what I did wrong, but I figured I would get feedback on these. Any comments are greatly appreciated!

Roof
Incorrect flashing. Flash where vertical surface is above roof plane.
Upper roof is higher than necessary.
Verify upper and lower east gutters are drawn independently.

Stair
Rails encroach southwest corner of CFA at top landing.

Ramp
Egress narrows at base of stair.

Thanks for the response!

Roof
Incorrect flashing. Flash where vertical surface is above roof plane. - That makes sense looking at the NCARB solution now, but the directions say "Flashing must be provided at all roof/wall surface intersections, including chimneys". So how why doesn't that also include when the vertical surface is below the roof plane?


Upper roof is higher than necessary. - Is there a maximum height limit that I should try and stay within? I used the minimum slopes and the minimum height at the clerestory

Verify upper and lower east gutters are drawn independently. - Gutters are drawn independently

Stair
Rails encroach southwest corner of CFA at top landing. - Got it!

Ramp
Egress narrows at base of stair. - I thought this was an issue, but I thought that the NCARB solution shows it this way on their solution.

Thanks again for the feedback!

Because you're showing roof flashing.

You didn't use the minimum height. You based upper roof height on a low roof elevation that doesn't impact the clerestory location.

They do, and their solution is wrong too.
