• <br /> Mr. Kurt Nelson <br /> Rice Fergus Miller <br /> Plan Check Number: B2001-027, First Building Review <br /> February 7, 2020 <br /> b. Section 9/A40.01 indicates the new wall will abut the underside of an existing concrete <br /> beam at the Main Level. It is presumed that the vertical reinforcement will dowel into the <br /> beam similar to Detail 8/S40.01. However, the wall reinforcement is not centered in the <br /> wall and is anticipated to conflict with the beam reinforcement. A detail specifying the <br /> construction at this location should be included. <br /> Gravity System: <br /> 6. The Main Level Framing Plan on Sheet S21.01, and Sections 2/S40.01 and 3/S40.01, specify <br /> framing to support the new concrete deck at the mechanical opening. The following comments <br /> should be addressed: <br /> a. The structural calculations do not appear to include a design for the north and south L4 <br /> spanning between concrete slab and exterior wall. Calculations substantiating the design <br /> should be submitted for review. Note that the concrete-topped metal deck is anticipated to <br /> have similar or greater flexural stiffness to the L4 and may act as the primary load path. <br /> Use of a more substantial flexural member is recommended. See IBC Sections 1604.1 and <br /> 1604.4. <br /> b. The connections between the north and south L4 and the supports do not appear to be <br /> included in the structural details. Note that the supporting angle in Detail 7/S40.01 <br /> upturned and will not facilitate the connections shown in Detail 3/S40.01. Additional details <br /> should be provided. <br /> 7. The Roof Framing Plan on Sheet S21.02 shows supplemental framing for new openings in the <br /> existing roof. Previous work performed per Permit No. B1402-011 includes additional framing in <br /> the work area that is not included in the plan. The plan also includes existing framing that is <br /> not shown in the previous permitted drawings. The existing framing in the work area should be <br /> verified and the plan revised as needed. See IBC Sections 107.2.1 and 1603.1. <br /> 8. The Roof Framing Plan on Sheet S21.02 shows new 4x8 beams and appears to show <br /> unspecified connections at the beam-to-beam connections. The make and model of the <br /> connections should be specified. Note that the beam west of the mechanical chase opening <br /> does not appear to show connections. See IBC Section 1603.1, 1604.1, and 1604.4. <br /> Lateral: <br /> 9. The Roof and Elevator Roof Plans on Sheet S21.02 reference Sections 6/S40.01, 8/S50.01, and <br /> 12/S50.01 for the elevator shaft construction. The sections reference the plans for the shaft <br /> wall construction, which does not appear to be specified. The elevator penthouse should be <br /> provided with a vertical lateral system. See IBC Sections 1603.1, 1604.1, 1604.4, 1609.1, ad <br /> 1613.1, and ASCE 7-10 Chapters 13 and 16. <br /> 0 3200 Cedar Street 0 425.257.8810 j"j `� everetteps@everettwa.gov <br /> Everett,WA 98201 425.257.8857 fax everettwa.gov/permits <br /> Page 6 Of'8 <br />
