SEISMIC – PARELLEL
TO THE STAIRS

The original design for the CMU wall did not have so many
openings in it, especially at the main south entry door.  Show that the new loads, along with the loads
for the original building, can be resisted by the remaining CMU wall.  Provide relevant digital drawings of the
original building and CMU wall design.

SEISMIC –
PERPENDICULAR TO THE STAIRS.

The south entry is a significant opening in the CMU wall
beneath this stair structure.  The
vertical rebar no longer go to the foundation. 
Provide calculations to show how the seismic design forces perpendicular
to the stairs are to be resisted.

SEISMIC ATTACHMENT
TO THE CMU WALL

Provide calculations showing the adequacy of the
attachments of the stair structure to the existing CMU wall, both in shear and
tension.

NEW BOND BEAMS

Details 8 and 9 on Sheet S5.01 show new bond beams at
beam attachment points.  How are these to
be constructed in the existing CMU?

WIND

This new stair enclosure extends above two different
roofs, each at a different height. 
Provide a design for wind that shows how wind forces travel through
code-compliant load paths to resisting elements.
