Black Pine.pdfFrom: Bjorback, Leif Sent: Tuesday, lune 24, 2014 2:43 PM To: 'Western Solar' Cc: Gahan, Andrew Subject: 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.

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.
