hot tub loading and deck live loads as these appear to be missing from the design calculations. If the hot tub is not intended to be placed on the elevated exterior deck, please provide gravity framing calculations for the new exterior deck as these appear to not conform to the prescriptive requirements of IRC 507 and WA State Code Interpretation 16-11. IRC 301.1.3. IBC 1604, 1605. 5. Please provide roof cover rafter joist spacing such that proposed roofing material can attach to as this appears to be missing from the plans. IRC 106.1.1. 6. On the first page of the deck cover design,there are notes indicating seismic/wind bracing options. While it is assumed that timber frames are the lateral force resisting system, it is unclear if these options were incorporated into the final design or are part of the construction documents. Please clarify the seismic/wind options as these appear to be preliminary design notes or contractor's option callouts. IRC 106.1.1. 7. On the permit calculations,the provided fastener schedule Item 4 indicates that a connection to the house is provided. Please verify that this connection meets the requirements of IRC 507.2 or provide an engineered connection that satisfy the load carrying requirements of IBC 1604.8.3. 8. Please provide anchorage calculations for the guardrails and the mounting hardware provided. Guards are required to withstand the forces indicated in Table R301.5 as these appear to be missing. 9. It is unclear if the use of the redundancy factor, p, has been applied to the lateral design of the exterior deck. Given the assumption that timber frames are used for the lateral system of the exterior deck structure, please verify the value of p, per ASCE 7-10 Sec 12.3.4.2. 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. All codes cited refer to the 2015 International Building Code(IBC),2015 International Existing Building Code(IEBC),the 2015 International Residential Code(IRC),the 2015 International Fire Code(IFC),the 2015 International Mechanical Code(IMC), and/or the 2015 Washington State Energy Code(WSEC),as amended by the State of Washington and adopted by the City of Everett. The current IBC referenced standard for accessible design is the 2009"Accessible and Usable Buildings and Facilities" (ICC/ANSI A117.1). Federal ADA regulations and standards may be more restrictive. These comments address building issues only.Additional revisions or additions may be required by other departments(such as Utilities,Traffic, Planning or Fire). All required submittals must be of sufficient detail and information to ensure that the proposed structure will be constructed in compliance with all adopted codes.
