Jeff Heilman, Development Technician--Public Works Department RE: Owner: Wong— 19`1'Avenue SE June 20,2018 age 3. The Second Floor Framing Plan on Sheet S2.2 references Section 3/S4.2 along the interior double walls. The section shows the joists parallel to the wall while the plan shows the joists perpendicular to the wall. The section or the reference should be revised. See IBC Section 107.2.1. Detail 7/S4.2 has been added and the detail callout on Sheet S2.2 has been updated. Gravity System: 4. The Second Floor Framing Plan on Sheet S2.2 appears to be missing floor joists at the top and bottom of the stair landings. The plan should be reviewed and revised as needed. See IBC Section 1603.1. Framing Spans have been added on Sheet S2.2 at the stair landings. 5. Sheet S2.2 shows Type B5 glulam beams at the middle of the units. The center and east units do not appear to include post supports at the west ends of the beam per Sheet S2.1. The design should be reviewed and revised as needed. See IBC Section 1603.1. Sheet S2.1 has been updated to include posts to support the B5 beams on the center and east unit. 6. The south wall of the Third Floor on Sheet S2.3 appears to be missing headers at the double windows. See the Front Elevation on Sheet A3.1 for clarity.Also,the post between the double windows should be specified. The plan should be reviewed and revised as needed. See IBC Section 107.2.1. The headers over the double windows are provided on sheet S2.4. There is only a single window on level 2,so an exterior wall supports the framing and walls above. S2.3 has been updated to callout a post size in between the double windows. 7. Sheet S2.4 shows Type RBI glulam beams at the middle of the units. The beams do not appear to have post supports at the west ends per Sheet S2.3. The design should be reviewed and revised as needed. See IBC Section 1603.1. S2.3 has been updated to provide posts to support each end of the RB1 on S2.4. 8. The Third Floor plan on Sheet S2.3 specifies Type B2 beams along the north sides of the units. The beams support the third story north wall and a portion of the third floor and roof. The beam does not appear to be supported by walls or posts per the Second Floor plan on Sheet S2.2 and the elevations on Sheets A3.2. The load path for the beam should be clarified.Note that the beam supports discontinuous shear walls. See additional comments below regarding this issue. See IBC Sections 1604.1 and 1604.4. The TJI joists cantilever to support the B2 beam along the north side of the units per detail 9/S4.2. This calculation is provided on page B-8 of the calculations. The B2 beam is designed
