1. Foundation Demo Plan — Clarify the difference in the size of the east isolated
footing in the center of the garage and of that required at that location on sheet
'AF1.0" — Foundation Plan.
Detail 1 on sheet AD1.0 — The dimension for the area of the slab to
demolished is 2'-6"x2'-6", which matches the 30"x3O" footing to be
installed. I

a. Indicate on the plans the required post to support the loads below the east
end of the proposed (4)2x8 HF #2 girder beam.
Detail 2 on sheet AF1.0 — The built-up (4)2x8 IIF #2 spans over the
existing 5 1/2'W%" GLB's. No post is required.
b. Clarify the callout for the (4)2x8 F -IF #2 to be used as a girder supporting the
post below the west end of the roof girder. It appears to be over spanned and
fails in bending. 'The tributary load may be reduced as a result of the
response to review comment'5b'. Indicate on the plans the required nailing
(size of fastener, spacing and arrangement, etc.) when specifying a 'built-up'
member.

4. Foundation Plan Key Notes:
a. Clarify the 'existing 6x8 glu-lam beam' identified in note 1.2'. Typically the
result of a process where multiple 1-1/2 inch thick members are glued
together, the depth of the beam is usually a product of the number of layers
multiplied by 1-1/2 inches. The specified width does not reflect that of those
commonly manufactured.

inspection of the required construction per the structural design.

5. Roof Framing Plan:
a. Clarify the reference to detail '2/S-1.0'— Interior Shearwall Connection —
along the interior wall between the `Hall' and the `Computer Room'. There
does not appear to be any other information elsewhere in the provided
construction documents indicating a shearwall at that location.
b. Clarify the callout for the 2x8 HF #2, installed at 16 inches on -center, to be
used as the upper roof rafters. They appear to be over spanned and deflect
beyond that allowed per table R301.7. There does not appear to be any
intermediate bearing elements represented on the provided construction
documents.
c. Clarify the callout for the (4)2x8 HF #2 to be used as a girder supporting the
upper and lower roof rafters. It appears to be over spanned, fails in bending
and deflects beyond that allowed per Table R301.7. The tributary load may be
reduced as a result of the response to the review comment above. Indicate on
the plans the required nailing (size of fastener, spacing and arrangement,
etc.) when specifying a `built-up' member.

7. Clarify the applicability of the provided lateral calculations to the proposed
project. The cover sheet notes an address different than that on the application
and the information contain therein does not appear to reflect the conditions
represented on the provided construction documents.
The address on the provided structural calculations is the correct project
