RE: Black Pine Spas
Markus, my staff ran a couple of calculations using the existing roof plan you supplied along with the weight of the
proposed arrays. Unfortunately, our numbers show that the existing roof framing members may be at or even slightly
beyond the design stresses allowed by code, even without the additional loading imposed by the solar arrays. If you are
to proceed with installing any additional weight on the roof, you will need to provide stamped engineering calculations
to justify doing so. Please advise as to how you wish to proceed with the permit application.

Leif,
Regarding the hardmount/seismic connection to the roof please reference the Eco65 product
guide cutsheet and test data. We will be using bracket option F-202. I have our Engineer working
out the calculations for the interconnection between the Eco65 hardmount anchor and the AET
Racking. They will also provide an updated set of plans that address ASCE- 7-10, 2012 IBC,
25lbs snowload, and that the structure of the building can adequately support the proposed PV
System.
Attached is a color copy of the ballast requirements. It clearly spells out what we are planning.
The valuation of $13,847 only includes the structural installation and does not include panels and
inverters. I appreciate you double checking this.
I apologize for not getting this information to you initially. Stay tuned as i will be passing
forward the necessary information as it is made available to me. I also included pictures of the
original plans for this building.
Kindest Regards,
MARKUS VIRTA

Hi Markus, I have reviewed the plans for your project, and have attached my comments that will
need to be satisfied before I can approve the building permit. Feel free to contact me if you have
questions.
