Ramp Vignette First Attempt

Postby cdimey » Tue Nov 28, 2017 8:47 pm

Any comments are very appreciated..
Also I was wondering, can the railing extensions at the base of the landings protrude into the 60" turning radius? Like at the base of the stairs here?
Can the 4" encroachment of the railings encroach into the 60" landings, or do the landings need to be wider to accommodate the railings?
Is it ok for the full ramp to be 60" wide to match the width of the landings?

You don't need a turning circle at base of stair, but egress width does narrow there. Distance from end of west rail to north wall can be no less than overall stair width. Best fix is to make stair 44".

Can the 4" encroachment of the railings encroach into the 60" landings, or do the landings need to be wider to accommodate the railings?

It depends. If turning circle is required (like at 12" landing) it must be clear. Other landings just need to be 5x5 min overall.

Yes.
