Per Section 1613. 1, W -(PV)/ W -(exist roof) = 3.2%, Increase Seismic Shear Load < 10%, -> [OK]
To Whom It May Concern,
Version 086.6 - 2
A jobsite survey of the existing framing system of the address indicated above was performed by a site survey team from Tesla. Structural
evaluation was based on site observations and the design criteria listed above.
Based on this evaluation, I certify that the alteration to the existing structure by installation of the PV system meets the prescriptive
compliance requirements of the applicable existing building and/or new building provisions adopted/referenced above.
Additionally, I certify that the PV module assembly including all standoffs supporting it have been reviewed to be in accordance with the
manufacturer's specifications and to meet and/or exceed all requirements set forth by the referenced codes for loading.
The PV assembly hardware specifications are contained in the plans/docs submitted for approval.
Sincerely
Abe De Vera, PE, SE
Structural Engineer.
