Ms. Waters:
Apri1 13, 2020
Pursuant to your request, we have reviewed your drawings aud the building for the installation of
the solar array at the above-referenced address.
Based on our review, we have determined that the existing roof stiucture is capable of supporting
the additional loading of thc solar array. The condition and capability of the structure is
suFficient for all loading conditions in accordancc with the requiremenYs of ASCE 7-10 and IBC
2015.
In addition, the total weight of the proposed an�ays in the proposed locations does not cause a
greater fhan 10% increase in lateral seismic forces experienced by any of the lateral load
resisring elements that this weight is tributa�y to, in accordance with the 2015 Inteinational
Building Code.
Pleasc feel free to contact ine if you have any comments or questions.
Respectfully yours,

Notes
1. CAUTION: Note screw tension to avoid damage to this profile.
2. CAUTION: These are cap-seam type profiles. The cap of this profile should be
mechanically fastened to the seam somewhere along its length with one lap tek.
3. SINGLE FOLD: These profiles are seamed to 90 degrees.
4. ATTENTION: The dimensioning on these seams is such that the clamp will not slip over
the seam. Some hand crimping at the clamp location will resolve this problem.
5. ATTENTION: Two piece clamp utilizes two M8 bolts & GX50, not setscrews.
6. ATTENTION: Two piece clamp utilizes one MS bolt & GXM50, not setscrews.
7. SETSCREW TENSION: Please note the setscrew tension. Panel has been tested with
increased setscrew tension.
8. ATTENTION: Load values averaged and reported based on 4 or more tests repetitions
performed.
9. ATTENTION: Test protocol preformed utilizing concealed standing seam clip.
10. ATTENTION: Clamp utilizes opposing setscrews.
11. ATTENTION: Two piece clamp utilizes one M8 bolt & GXM10, not setscrews.
12. ATTENTION: Two piece clamp utilizes two MS bolts & GX10, not setscrews.
This table represents tensile loads applied to the clamp in a direction parallel to the panel seam. Panels must
be adequately attached to the structure at their point of fixity to resist these loads. Allowable loads are listed
utilizing a default Factor of Safety (FS) = 2.0. Actual factor of safety is the responsibility of the designer and
should be employed as appropriate. Enter desired Factor of Safety and reset/re-tabulate.
All tabled values are dependent upon setscrew tension. Load testing of S-5!O clamps is conducted with
setscrews tensioned at 150 inch pounds (22 gauge steel profiles) or 115 inch pounds (24 gauge steel and all
other metals). When relying upon published load values, setscrews should be tensioned and verifed using a
calibrated torque wrench between 160 and 180 inch pounds when used on 22ga steel and between 130 and
150 inch pounds for all other metals and thinner gauges of steel.
