RE: Building Permit Structural Plan Review – First Submittal
17425 120th Lane SE (B25006585)
Dear Mr. Goetz:
We reviewed the proposed project for compliance with the structural provisions of the
2021 International Existing Building Code (IEBC) and 2021 International Building Code
(IBC) as amended and adopted by the State of Washington and the City of Renton. The
design team should address the comments below.
Responses to the review comments below should be made in an itemized letter form
and any changes to the drawings should be clouded. We recommend that the permit
applicant have the structural engineer respond and resubmit for additional review.
All information should be submitted directly to the City of Renton.
Structural
General
1. In light of the drawings indicating preservative-treated lumber, the drawings
should be revised to indicate the lumber shall be treated to the AWPA U1-16
(plant or shop treatment) and M4-16 (field treatment) standards. Below is an
image from Sheet S-1 with our redlined comments which need to be resolved
and our highlighted marks. The revised drawings should be submitted for
review. See IBC Sections 107.2.1, 1603.1, and 2303.1.9.

2. A note should be added to the section of the structural notes on PT Wood,
Sheet S-1, stating that fasteners, including nuts and washers, installed in
preservative-treated wood shall be hot-dipped zinc-coated galvanized with a
minimum coating weight complying with ASTM A 153. Fasteners other than
nails, timber rivets, wood screws, and lag screws are permitted to be
mechanically deposited zinc-coated with coating weights complying with ASTM
B 695, Class 55 minimum. Below is an image from Sheet S-1 with our redlined
comments which need to be resolved as well as our highlighted marks. The
revised drawings should be submitted for review. See IBC Sections 2304.10.6
and 2304.10.6.1.
3. The drawings, such as Sheet S-1, indicate the use of lag bolts/ lag screws and
nails. To what standards are the lag bolts/ screws (ANSI/ASME Standard
B18.2.1?) and nails (ASTM F1667?) to meet? Please note, per the 2018 NDS
Section C12.1.4.1, ANSI/ASME Standard B18.2.1, the metal strength must be
specified by the designer. See the footnotes in NDS Tables 12K and 12J (for lag
screws: Fyb = 70 ksi for D = 0.25”, Fyb = 60 ksi for D = 0.3125”, and Fyb = 45 ksi for
D ≥ 0.375”). Below is an image from Sheet S-1 with our redlined comments
which need to be resolved. The drawings should be revised to clarify what
standards and material strengths are to be met. The revised drawings should
be submitted for review. See IBC Sections 104.1, 107.2.1, 1603.1, 2306.1, and
2307.1.

4. The inspection note on Sheet S-1 appears to include an outdated reference.
Below is an image from Sheet S-1 with our redlined comments which need to
be resolved. The revised drawings should be submitted for review. See IBC
Sections 107.2.1 and 1603.1.
5. Our review notes the submitted drawings do not include abbreviations list
which defines the abbreviations indicated on the drawings. The drawings
should be revised to include such a list so as to define the design intent. Below
is an image from Sheet S2.1 with our redlined comment which need to be
resolved. The revised drawings should be submitted for review. See IBC
Sections 107.2.1 and 1603.1.

6. Is the design intent to have the proposed Simpson hardware to be fully nailed/
screwed to the attached lumber (i.e., no empty holes in the connecting part of
the hardware). The drawings should be revised to include such a list so as to
define the design intent. The revised drawings should be submitted for review.
See IBC Sections 107.2.1 and 1603.1.
Corrections and comments made during the review process do not relieve the permit
applicant or the designers from compliance with code requirements, conditions of
approval, and permit requirements; nor are the designers relieved of responsibility for
a complete design in accordance with the laws of the state of Washington. This review
is for general compliance with the International Existing Building Code and
International Building Code as they relate to the project. See IBC Section 105.4.
If you have any questions or need additional clarification, please contact us.
Sincerely,
Alan D. Findlay, P.E.
