Dear Mr Fleming: Approval Date If -
RE: Corn / Sandison Residence, 3713 Mt Angeles Road, Port Angelefff
This is to report on my analysis of the Corn / Sandison residence roof system to
satisfy City requirements for a licensed engineer's opinion on structural adequacy of
this roof to support new solar panels.
The roof must support a total gravity load of 43.4 pounds per square foot. This is from
25 psf snow load, the existing 15.4 psf dead load, and an additional 3 psf panel load.
From Winborn Architects criteria I understand that the trusses were designed for 42
psf total load. Therefore, in my opinion, the roof system will support the required
gravity load, including solar panels.
Wind uplift loads at this location are roughly 30 psf. The roof has 2x6 trusses (at a
6:12 slope) with 24" spacing. The intent is to fasten mounting feet into the truss top
chord using 24" spacing along the array perimeter and with 24" & 48" spacing in the
field. This requires a 5/16" x 3" lag bolt, with minimum 1.5" penetration into the top
chord, at all mounting locations. With this connection the roof is also capable of
resisting wind loads on the solar panel array.
Panel locations are shown on the roof framing plan you provided. You also provided
panel details and manufacturers literature on the proposed Unirac mounting system.
My engineering calculations are attached. Please note, these are consistent with
requirements in the 2102 1 BC and ASCE Manual 7-10, Minimum Design Loads for
Buildings and Other Structures.
I trust that you will find this work satisfactory. However, if something additional is
needed, please let me know.
R pectfully;
Harold T Andersen, PE

raft-R-mateO attic vent is an extruded polystyrene foam vent designed to
assure unrestricted airflow from the soffit to the ridge vent by preventing attic
or rafter cavity insulation (batt or blown) from covering eave or soffit vents, or
from expanding to fill the code required air space for roof ventilation.
raft-R-matee Vent is now designed with a hinge to allow it to be attached to
the exterior wall top plate and roof deck, blocking insulation from clogging the
soffits while getting the highest possible R-value at the eaves.

RE: Engineering Certification for UniRac SolarMountTm
Universal PV Module Mounting System
Dear Sir:
I have reviewed Unirac SolarMountTm"Code-Compliant Installation Manual 227.3",and
certify that the information and results are accurate. To determine the design level forces,
the appropriate wind speed shall be determined as prescribed by local jurisdiction
requirements and applied in accordance to the Washington State Building Code that
references International Building Code-2009 or International Residential Code-2009 and
ASCE 7-05. Unirac's Manual 227.3 utilizes ASCE 7-05 for which Unirac Table 2 is
based upon,and that is dependent upon conditions of spatial form,height and other
structure parameters that are specified in the code provisions for determining the applied
wind loading pressures imposed onto the Unirac SolarMountTm rails supporting solar
panels.The SolarMountTm railing and anchorage requirements for the installation are
properly represented in the Installation Manual 227.3.
For other conditions,the determination of wind pressures should be determined by the
aforementioned International Building Code—2009 and ASCE 7-05 procedures.
The International Building Code requires that wind loading be determined based upon
ASCE 7-05 Simplified Method 1 or ASCE 7-05 using Method 2,that which is dependent
upon conditions of spatial form, height and other structure parameters that are specified
in the code provisions for determining the applied wind loading pressures imposed onto
the Unirac SolarMountTm rails supporting solar panels.
James A. Marx,Jr.P.E.
Page 2 of 2
The design verification is based on:
1. ASCE7-05—ASCE Standard
11. "Steel Construction Manual," 13th Ed.,American Institute of Steel
Construction,Chicago,IL,2005.
111. "Aluminum Design Manual", The Aluminum Association, Washington D.C.,
2005.
IV. Mechanical Properties and Static Load Testing of Unirac extruded rails and
related components obtained from Dr. Walter Gerstle,PE,Department of
Civil Engineering,University of New Mexico,Albuquerque,NM
Use:
Unirac SolarMountTm is evaluated for use in locations where wind pressure reguirements
do not exceed 50 r)sf or snow load conditions do not exceed 45 psf ground snow loads.
For loading in excess of either of the above stated conditions, Unirac,Inc. should be
contacted for suitability of installation.
By this letter, I certify that the Unirac SolarMountTm assembly,when installed in
accordance with the Installation Manual 227.3 will meet the requirements of the building
codes adopted by State of Washington. Others should evaluate the structure to which the
Unirac SolarMountrm system is to be connected on a case-by-case basis,per Part I—
Installer's Responsibilities of the Installation Manual,to ensure its adequacy to accept
attachments and to support all applied loadings per the building code.
Please call me if you have any questions or concerns.
Sincerely, N N A 1".

L Installer's Responsibilities
Please review this manual thoroughly before installing your SOLARMOUNT is much more than a product.
SOLARMOUNT system. It's a system of engineered components that can be assembled
This manual provides(1)supporting documentation into a wide variety of PV mounting structures.With
for building permit applications relating to Unirac's SOLARMOUNT you'll be able to solve virtually any PV module
SOLARMOUNT Universal PV Module Mounting system,and mounting challenge.
(2)planning and assembly instructions for SOLARMOUNT It's also a system of technical support:complete installation
SOLARMOUNT products,when installed in accordance with and code compliance documentation,an on-line
this bulletin,will be structurally adequate and will meet SOLARMOUNT Estimator,person-to-person customer
the structural requirements of the IBC 2009 and IBC 2012, service,and design assistance to help you solve the toughest
ASCE 7-05,ASCE 7-10 and California Building Code 2013 challenges.
(collectively referred to as"the Code"). This is why SOLARMOUNT is PVs most widely used mounting
system.
The installer is solely resl2onsible for:
- Complying with all applicable local or national building codes,
including any that may supersede this manual;
- Ensuring that Unirac and other products are appropriate for
the particular installation and the installation environment;
- Ensuring that the roof,its rafters,connections, and other
structural support members can support the array under all
code level loading conditions (this total building assembly is
referred to as the building structure);
- Using only Unirac parts and installer-supplied parts as
specified by Unirac (substitution of parts may void the
warranty and invalidate the letters of certification in all Unirac
publications);
- Ensuring that lag screws have adequate pullout strength and
shear capacities as installed;
Verifying the strength of any alternate mounting used in lieu
of the lag screws;
Maintaining the waterproof integrity of the roof,including
selection of appropriate flashing;
Ensuring safe installation of all electrical aspects of the PV
array;
Ensuring correct and appropriate design parameters are
used in determining the design loading used for design of the
specific installation.Parameters, such as snow loading,wind
speed, exposure and topographic factor should be confirmed
with the local building official or a licensed professional
engineer.

Keep rail slots free of roofing grit or other debris. Foreign matter will
cause bolts to bind as they slide in the slots.
Installing Splices:If your installation uses SOLARMOUNT splice bars,
attach the rails together(Fig.13)before mounting the rails to the
footings. Use splice bars only with flush installations or those that use
low-profile tilt legs.

Subject: Quick Mount PV Load Testing
loc-ES AC13 &.ASTM.D 1761
Dear Mr. Wentworth:
As requested, Applied Materials & Engineering, Inc. (AME) has completed load-testing Quick Mount
PV system anchors for shear andlensile strength. The purpose of our testing was to.evaluate the tensile
and shear load capacity of the Quick Mount PV system in a high density (Douglas Fir) and a low density
wood (Cedar).
SAMPLE DESCRIPTION
Twelve (12) 12"xl2" samples with.2-1/4" X 3-1/8" Unirac Angle.were delivered to our laboratory on
April 26, 2009; six each for Douglas Fir and Cedar. A copy of the installation instructions is provided in
Appendix A. Typical sample photo is providedin Appendix B.
PROCEDURES.&.RESULTS
Since an acceptance criterion(AC)has not been developed for this product,the samples were tested
under the direction of Mr. Yamil Moya, P.E. with ICC-ES, and in general accordance with applicable
procedures outlined in ASTM D 1761 and AC13.
a. Tensile.Strength
Three samples each of the two types of wood were tested for tensile strength on April 2.8, 2009 using a
United Universal testing machine. Samples were rigidly attached to the testing machine and a tensile
load was applied to the Unirac Angle at a displacement rate 0.1 inches per minute without shock until
failure. Detailed results are provided in Table 1. Based on these results, the average tensile strength of
the hanger bolt in Douglas Fir and Cedar wood species were determined to be 2554 lbf and 1355 lbf,
respectively.

United Universal testing machine. Samples were rigidly attached to the testing machine and a shear load
was applied to Unirac Angle at a displacement rate 0.1 inches per minute without shock until failure.
Detailed results are provided in Table II. Based on these results, the average shear str'
ength of the hanger
bolt in Douglas Fir and Cedar wood species were deten-nined to be 2203 lbf and 1957 lbf, respectively.
Photographs illustrating typical setups are provided in Appendix C.

RESPECT THE ROOF 925-478-8269
Stamped Engineering Test Reports Do Not Expire
To whom it may concern,
Quick Mount PV offers extensive testing for all our products conducted by a third-party
licensed professional engineer. All our third-party engineering reports are stamped by a
licensed professional engineer at the time the reports were prepared and do not expire.
Our engineering reports continue to be valid as long as the professional engineer's
license (date within the stamp) was valid when the reports were prepared (the report
date). Even if the license has expired between the time the engineering reports were
prepared and the time when a local agency reviews them,the reports do NOT need to be
re-stamped with a current stamp.
This information is written into California State law under the Professional Engineers Act
within the Business and Professions Code (B&P Code §§ 6700-6799).The California Board
for Professional Engineers and Land Surveyors(BPELS) provides further clarification of the
code in their Guide to Engineering & Land Surveying for City and County Officials, page
12 section 27,which is cited below.
27. If the license has expired between the time the engineering documents were
prepared and the time when the local agency's review is performed,do the documents
need to be re-sealed by a licensee with a current license? IMP Code §§ 6733, 6735,
673S.3,6735.4)
As long as the license was current at the time the engineering documents were prepared,
the documents do not need to be re-sealed prior to review by the local agency. However,
any changes (updates or modifications) to the documents that are made following the
review by the local agency would have to be prepared by a licensed engineer with a current
license and those changes would have to be signed and sealed.
It should also be noted that as of January 1,2010 professional engineers are not required
to include their license expiration date when they sign and stamp engineering
documents only the date that they signed the document (B&P Code §§ 6735, 6735.3,
6735.4, 6764, 8750, 8761 &8764.5). Links to all of the codes and guides referenced in this
letter may be found online at quickmountpv.com under FAQ. Please submit any further
questions to te,ch@quickmountpv.com.
