All 3 3.1 Alt Vignettes - Comments appreciated!!

Testing next week so comments are much appreciated!

3.1_Ramp sm att 1_170411.jpg


First attempt at the 3.1 ramp vignette - is it ok to end the ramp facing the taller parts of the elevated landing/ramps as shown?

3.1 Roof Plan att 1_17-0411.jpg


Should I break the roof plane at the chimney?

3.1_Stair L1 sm att 1_170411.jpg

Since there is a portion of the landing that theoretically could be run into (under 80" head clearance) if someone were to turn around/go at a super hard angle towards the egress doors, would that be a fatal error? Or should I place a railing in that portion for detection even though it's not a part of the code req's?

Thanks in advance for all your help! This forum has definitely helped me weed through these confusing vignettes.

Yes, as long as you maintain the egress width (60") all the way through to the exit.

No.

No.

Ramp
Don't reduce existing egress width until both ramp and stair are accessible.
Remove extension at 6" landing inner rail.
6" landing is too small.
Why does the southern rail return at the wall?
Hold rails 2" off walls and edges.
Don't draw zero landing.
Don't cross rails into path of egress.

Roof
Why does low roof start higher than 9-6?
Upper roof is too low.
Too many skylights.

Stair
Stair narrows indirection of egress.
Upper runs are wider than required.
Remove inner rail extensions at 3' landing.
Why is there a rail return at the southwest corner?
Stop rails at cut lines.
Hold rails 2" off walls and edges.

Thanks for the feedback Coach!

Here are my second tries.

I revised the lower roof height but out of curiousity would a low roof that started higher than the min 9'-6" be acceptable?
