Dear Mr, Walter:
I have completed a preliminary plan review of your ilPplication for the proposed new
single family residence located ~n~Q1.6_Ee~nhill Loop,.Springfield, Oregon, The ,
following items require additionarinformation, clarification or correction in order to
complete the review, approve the application, and issue permits,
I, The lateral engineering by Mr. Nava contains'a note in the table on page 7
regarding required revisions to the mudsill and anchor bolt spacing, The same
table on the drawings does not contain information in or reference to engineer's
note, Please clarify the Shearwall Schedule & note #7 on sheets L I & L2 to
provide the engineer's note, or reference to the note, on the construction drawings
in an appropriate manner.
2, The Foundation Plan notes that floor joists at the rear wall are to "Drop" into joist
pockets in the foundation wall. A detail of this condition is necessary since it is
not a common condition. The detail should demonstrate that the joists can be
properly placed into "pockets" with required bearing area and secured to prevent
joist rotation and other displacement, while maintaining the required stemwall
thickness, (R502,7 & Table 404,1,1(1) Footnote h)
3, A note on the foundation plan indicates that the typical footing is to be 15 inches
wide with an 8 inch stemwall. The front elevation shows a full height masonry
veneer applied to the face, which will require additional footing width, Also,
~
portions of the exterior building walls will support the third floor load, This also
will require a larger footing, No information or details are provided for these
conditions. Please provide the necessary information for footings required to be
larger. (R403.1 & Table R403,1)
4, Ridge boards & hip and valley rafters must be of sufficient depth to cover the cut
face of the reauired depth of rafters, Thus, if the required nominal depth of rafter
is 10", the ridge, hip or valley board must be a full 13" deep, However, if the
required depth of rafter is only 8", regardless of the size used, then the boards
connecting to the cut face of the rafters would be required to be a full 10-1/4"

"
deep, and if only 6"depth is required, the boards would need to be at least 7-3/4"
deep, The forgoing is based on a 12:12 roof pitch.
The vertical load analysis appears to indicate the 3rd floor walls are bearing walls,
The plans do not show this, Since the required rafter size is dependent on the
location of supports, the required size of ridge boards al1d hip & valley rafters will
vary accordingly, Please clarify the location of bearing walls on the 3rd floor and
verify that the reauired size of rafters has full cut-face connection to the ridge, hip
and valley boards at all locations,
5, The vertical load analysis (Beam Calculations) does not adequately show how the
applied loads were determined, I have been unable to verify the appropriateness
of many of the loads used in the beam check calcs, The vertical load analysis is
not stamped and signed by a licensed architect or engineer. Thus, verification of
the applied loads used in the calculations is critical. Please provide appropriate
information on how the applied loads were determined for each member in the
calculations, or provide a vertical load analysis for the building that is.signed and
stamped by a licensed architect or engineer.
Because the information needed is necessary to complete your review, the project will be
placed on "Hold" until we receive the required information, Once I have received the
information requested above, we will resume our processing of your application and
phone you once your application has been reviewed, Please be aware that processing your
application may require an additional two weeks from the day we receive the requested
information,
If you have any questions, please feel free to phone me at 726-3623,
