Mr. Randy Heltne <br /> Everett Housing Authority <br /> Plan Check Number: B1807-032, Second Review <br /> October 17, 2018 <br /> Gravity System: <br /> 11.This comment has not been completely addressed. The load path appears incomplete. See <br /> IEBC Sections 807.4 and 1103.2, and IBC Sections 107.2.1, 1603.1, 1604.1, and 1604.4. The <br /> following comment should be addressed: <br /> a. Sheet A-7 specifies replacement of the existing ridge beams with new PSL beams. The <br /> existing beams support existing roof joists framing in from both sides. Clarify how the <br /> ridge beam will be replaced. Details for connections between the beams and the joists and <br /> supports shall be provided in the structural drawings. <br /> b. The existing 4x4 wood posts supporting the existing roof will bear on new framing at the <br /> Main Floor story per Sheet A-1. The following components of the load path shall be <br /> addressed: <br /> i. Positive connections shall be provided between the existing posts and the supporting <br /> beams. <br /> ii. Positive connections shall be provided between the new beams and supporting posts. <br /> iii. The post sizes at several locations are not specified. <br /> iv. Positive connections should be provided between the posts and the beams below. <br /> Where the posts do not extend through and bear directly on the posts, details showing <br /> revisions to the floor framing to transfer the loads from the posts to the beams below <br /> shall be included. <br /> v. The 6x12 beam supporting the south roof post indicates a HU-series hanger. The <br /> required hanger model should be specified. <br /> c. The new posts from the roof framing will bear on new framing at the Ground Floor story <br /> per Sheet A-2. The following components of the load path shall be addressed: <br /> i. The northern roof post should be supported by two posts per Sheet A-1. Sheet A-2 <br /> only shows one post. The position of the post and of the supporting 4x18 beam do not <br /> align with the posts above. The framing should be revised. Dimensions coordinating <br /> the location of the beam should be provided. <br /> ii. The PSL beam providing support for the northern roof post terminates at the north <br /> exterior concrete wall of the building. The beam end should be provided with a <br /> support. <br /> iii. The eastern post supporting load from the south existing roof post should bear on the <br /> PSL library door header. The post is not shown. <br /> iv. Hanger interconnecting the beams, and positive connections between the beams and <br /> posts, should be specified. <br /> d. Foundation improvements have not been provided to support concentrated loads from the <br /> roof above. Verify if new foundations are required. Details and calculations shall be <br /> submitted for review as needed. <br /> 12.This comment has not been completely addressed. See the original comment and revised <br /> Comment 11c above for additional information. See IBC Sections 107.2.1, 1604.1, and 1604.4. <br /> 13.This comment has not been completely addressed. The roof framing plan on Sheet A-7 has <br /> been revised and specifies both truss and 2x overframing west of the existing wall line. The <br /> required construction should be reviewed and revised. See IBC Section 1603.1. <br /> •a•e6of10 <br /> CITY OF EVERETT • 3200 Cedar Street • Everett,WA 98201 • (425) 257-8810 • Fax(425) 257-88 <br />
