The calculations do not address wind loading on the proposed units. Given the size of the units, wind loads potentially control the design of the anchoring, especially in consideration of the rooftop equipment factor per ASCE 7. Please provide updated calculations including wind load evaluation, and revised anchorage details as necessary.
Reference: IBC Section 1605.1, 1609.1.1; ASCE 7 Section 6.5.15

Refer to Calculations Pg. 4. The determination of the wind load does not appear to include the rooftop equipment factor per ASCE 7. Given the size of the building, an additional factor of 1.9 is required.
Reference: IBC Section 1609.1.1; ASCE 7 Section 6.5.15.1
