OK <br />PV Panel W 3.00 psf <br />Area of panel 320.00 ft2 <br />Total Roof W 586.58 lbs <br />% increase=(Wadditional)/Wexisting 1.34% <br />The increase in weight as a result of the solar system is less than 10% of the existing structure and therefore no further <br />seismic analysis is required. <br />Limits of Scope of Work and Liability <br />Existing structure is assumed to have been designed and constructed following appropriate codes at <br />time of erection, and assumed to have appropriate permits. The calculations produced are only for the <br />roof framing supporting the proposed PV installation referenced in the stamped planset and were <br />completed according to generally recognized structural analysis standards and procedures, professional <br />engineering and design experience, opinions and judgements. Existing deficiencies which are unknown <br />or were not observable during time of inspection are not included in this scope of work. All PV modules, <br />racking, and mounting equipment shall be designed and installed per manufacturer's approved <br />installation specifications. The Engineer of Record and Engineerinc assume no responsibility for misuse <br />or improper installation. This analysis is not stamped for water leakage. Framing was determined based <br />on information in provided plans and/or photos, along with engineering judgement. Prior to <br />commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the <br />stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any <br />discrepancies prior to starting construction. Contractor shall also verify that there is no damaged framing <br />that was not addressed in stamped plans, calculations, and cert letter (where applicable) and notify the <br />Engineer of Record of any concerns prior to starting construction. Prior to the commencement of work, <br />the contractor shall verify the existing roof and framing conditions. Notify Engineerinc and the engineer of <br />record of any Discrepancies prior to starting construction. Prior to the commencement of work, the <br />contractor shall inspect framing for any damage such as water damage, cracked framing, etc. and notify <br />the E.O.R. if any issues are found.These plans/calculations are stamped for structural code compliance <br />of the roof framing supporting the proposed PV installation reference only. These plans/calculations are <br />not stamped for water leakage. PV modules, racking, and attachment components must follow <br />manufacturer guidelines and requirements. <br />303 N.
