RE: Plan Check: BLD2014-0698 — Corrected Plans
Project: Demaray addition
Project Address: 505 10th Avenue N
Dear Chuck:
Please find delivered herewith a set of corrected plans for my proposed addition. I believe we
have made the corrections that you requested in your letter of August 19. A more detailed
examination of the existing structure was undertaken with a great deal more drywall removed to
expose the existing framing which revealed a number of existing engineered trusses that were not
noted in the previously submitted plans.
Please contact me if you have any further questions. Thank you for your time and consideration.

RESPONSE AND REVISION 11
September i
Response to Ch cl Millerg Plans Examiner
RE: Plan Check: BLD2014-0698
Project: Demaray addition
Project Address: 505 10th Avenue N
During a review of the plans by the Building Division for the above noted project, it was found
that the following information, clarifications, or changes are needed. A complete review cannot
be performed until the revised plans/documents, including a written response indicating where
the `clouded' or otherwise highlighted changes can be found on the revised plans, have been
submitted to a Permit Coordinator. Reviews by other divisions, such as Planning, Engineering, or
Fire, may result in additional comments.
General Note — Indicate on the plans the option to be selected to achieve the required 0.5 credits
per WSEC R406.
See note on Sheet A-1 indicating the flan for this credit 'hi hli hte in yellow)
On sheet A--1:
General Notes - Change the code year reference from `2009' to `2012' for the following:
a. Note #1 - correction made (highlighted in yellow)
b. Note #4 - correction made (hila.,hli hted in yellow)
2. Floor Plan — Indicate on the plans the following:
a. The required smoke alarm per R314. - correction made (hi-hli Ated in yellow)
b. The required carbon monoxide alarm per R315. correction made (hi hli�hted in
yellow
3. Framing Plan
An additional more detailed examination of the structure was undertaken with
much more drywall removed to expose the existing framing which revealed errors in the
previously submitted plans for the existing structure. In fact, engineered trusses are in
present and in place that were not known or noted in the original plans. 'These existing
trusses are now highlighted in the framing plan as noted on Sheets A-1 and A-2, as well as
structural calculations for the loads in the areas noted in paragraphs a b, c, and d below.
a. Clarify the callout for the `Existing Beams A' — 2x10 tripled joist — to be used to
support the loads from the walls and roof framing above the `Office'. They appear
to be over spanned, fail in bending, and deflect beyond that allowed per Table
R301.7. The uniform loads used in the provided structural calculations do not appear
to reflect those anticipated by the represented construction and are a bit low. The wood species
used in the provided structural calculations (Douglas Fir -Larch #2) is different than that noted in
the `General Structural Notes' (Hem Fir #2).
See highlighted framing plan showing existing trusses and new calculations with existing
trusses in this area.
b. Clarify the callout for the `HU210-3' joist hanger to be used to support the `Existing
Beam A' — 2x10 tripled joist. Per the manufacturer it appears to be unable to support the loads
anticipated by the represented construction.
See highlighted framing plan showing existing trusses and new load calculations with
existing trusses in this area as well as planned hanger.
c. Indicate on the plans the required connection to support the loads at the ends of
the`Existing Beam A' — 2x10 tripled joist — where not specified to guide proper
construction and inspection.
See highlighted framing plan showing existing trusses and new load calculations in this
area
d. Clarify the callout for the `Existing Beam B' — 2x10 tripled joist — to be used to
support the loads from the floor, the two `Existing Beams A', and the wall and roof
framing above the 'Office'. It appears to be over spanned, fails in bending, and
deflects beyond that allowed per Table R301.7. The uniform loads used in the
provided structural calculations do not appear to reflect those anticipated by the
represented construction and are a bit low. The point load from the east `Existing
Beam A' does not appear to have been accounted for. The wood species used in the
provided structural calculations (Douglas Fir -Larch 42) is different than that noted in
the `General Structural Notes' (Hem Fir #2). )
See highlighted framing plan showing existing trusses and new load calculations in this
area
On sheet A-2:
4. Section AM
a. Change the required wall insulation from `R-19' to `R-21' per WSEC Table
R402.1.1. - correction made (highlighted in yellow)
b. Indicate on the plans the required sill height of not more than 44 inches measured from
the finished floor to the bottom of the clear opening per R310.1.
- correction made (highlighted Jin yellow)
