Northlake Way Seattle,WA 98103 RE: Owner: Ms. Barbara Stephanus c/o Epic Management Job Address: 9300 West Mall Dr Plan Check Number: B1701-040 through -042 Dear Mr. Nicholas, In response to your application for a construction permit,your plans have been examined and you are advised that revisions may be necessary before a permit can be issued. Please review and respond to the comments below. These comments address building issues only. Additional revisions or additions may be required by other departments (such as Public Works, Planning, or Fire). All references refer to the 2015 International Building Code (IBC),the 2015 International Existing Building Code (IEBC),the 2015 International Property Maintenance Code (IPMC),the 2015 International Fire Code (IFC),the 2015 International Mechanical Code (IMC), and the 2015 International Energy Conservation (IECC), as amended by the State of Washington (WSEC) 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, FHA, and HUD regulations and standards, including the Fair Housing Accessibility Guidelines may be more restrictive. In order for the processing of your application to continue, it will be necessary to provide the Building Division with two complete new sets of stamped and signed construction documents and calculations reflecting the corrections requested. Structural 1. On the General Structural Notes,sheet S1.0"Building Code&Reference Standards",the design code used for this project is the IBC 2015. However, on the permit structural calculations where the wood shear walls are checked against the design demands (for example, Bldg A 1st Floor Walls), it appears that the IEBC Section 404.2.1 is used to check for 75% of the IBC 2015 design demands, which is in conflict with the intent of the using the IBC 2015 full lateral design demands for wood shear walls. Please verify which code is being followed for the design of the wood shear wall repair and update the drawings and notes as required for the appropriate building code. 2. On the permit structural calculations where the wood shear walls are checked against the design demands(for example, Bldg A 1st Floor Walls),the use of HDU 5 holddown anchorage appears to exceed the Demand Capacity Ratio (DCR) by nearly a factor of 3.0 (10.9 kips/ 3.8 kips = 2.87) even when using 75% of the lateral forces in the IBC 2015. Please provide an alternate detail and calculations for these HDU5 holddowns that are exceeding the DCR values of 1.0. 3. On the permit structural calculations where the wood shear walls are checked against the design demands (for example, Bldg A 1st Floor Walls), exceed the Demand Capacity Ratio (DCR) by nearly 14%. It is unclear if the 75% of the IBC 2015 lateral forces is being used (for example, 531 plf/ Page-1-4-2 CITY OF EVERETT • 3200 Cedar Street • Everett,WA 98201 • (425) 257-88 ax(425) 257-8857
