Professional Engineer projects@creng.solar Code:2020 MINNESOTA BUILDING CODE (ASCE 7-16) Ult Wind Speed: Exposure Cat: After review of the field observation report and based on our structural capacity calculations in accordance with applicable building codes, the existing roof framing supporting the proposed solar panel layout has been determined to be: adequate to support the imposed loads. Therefore, no structural upgrades are required. 4/20/2022 A field observation was performed to document the existing framing of the above mentioned address. From the field observation, the existing roof structure was observed as: Shingle roofing supported by 2x4 Truss @ 24 in. OC spacing. The roof is sloped at approximately 26 degrees and has a max beam span of 8 ft between supports. Design Criteria: 4/20/2022 Everlight Solar Construction 7369 Highway 13 W Savage, MN 55378 Attn.: To Whom It May Concern re job:INFORMATION Jason Benda 20347 Kensington Way Design Criteria: Code:2020 MINNESOTA BUILDING CODE ASCE 7-16 Live Load:20 psf Ult Wind Speed:115 mph Exposure Cat:B Ground Snow:50 psf Min Roof Snow:NA Current Renewables Engineering Inc. Professional Engineer projects@creng.solar 4/20/2022 The following calculations are for the structural engineering design of the photovoltaic panels and are valid only for the structural info referenced in the stamped plan set. The verification of such info is the responsibility of others. After review, I certify that the roof structure has sufficient structural capacity for the applied PV loads.

Limits of Scope of Work and Liability: Existing structure is assumed to have been designed and constructed following appropriate codes at time of erection, and assumed to have appropriate permits. The calculations produced are only for the roof framing supporting the proposed PV installation referenced in the stamped planset and were completed according to generally recognized structural analysis standards and procedures, professional engineering and design experience, opinions and judgements. Existing deficiencies which are unknown or were not observable during time of inspection are not included in this scope of work. All PV modules, racking, and mounting equipment shall be designed and installed per manufacturer's approved installation specifications. The Engineer of Record and the engineering consulting firm assume no responsibility for misuse or improper installation. This analysis is not stamped for water leakage. Framing was determined based on information in provided plans and/or photos, along with engineering judgement. Prior to commencement of work, the contractor shall verify the framing sizes, spacings, and spans noted in the stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any discrepancies prior to starting construction. Contractor shall also verify that there is no damaged framing that was not addressed in stamped plans, calculations, and cert letter (where applicable) and notify the Engineer of Record of any concerns prior to starting construction.
