Please review and respond to the comments below. Structural 1. It appears that the proposed unit will be anchored into the curb assembly that is located on the roof level of the building as shown on Detail 1/M5.0. The callout refers to a structural drawing that does not appear to be included in this submittal. Please provide clarification to the anchorage of the new unit. If the anchorage needs to be designed, please refer to ASCE 7-10 Chapter 29 for wind force requirements or ASCE 7-10 Chapter 13 for seismic loading requirements, whichever governs the anchorage design. 2. It is unclear from the drawings what the change in weight from the old unit to the new, proposed unit will become. Per IEBC 2015 Sec 707.2, if the change of weight between proposed and existing units increases existing framing member stresses by more than 5%, the existing framing will need to be evaluated by an engineer and provide stamped calculations and drawings indicating any strengthening or stiffness upgrades for the new unit, if strengthening is required. Please provide drawings, calculations, and a narrative as required. In order for the processing of your application to continue, it will be necessary to provide the Building Division with two new sets of revised construction documents reflecting the corrections requested. Please include a response letter indicating how the corrections were resolved. O 3200 Cedar Street 0 425.257.8800 0 everettpw everettwa.gov PjOEverett,WA 98201 425.257.8882 fax everettcr
