Ms. Dawn Bushnaq Bushnaq Studio Architecture + Design Plan Check Number: B2109-083, First Building Review February 2, 2022 exposure. If preservative -treated posts are provided, revised calculations substantiating the design for reduced capacities may be required. See IBC Sections 2304.12.2.2 and 2306.1. 6. The architectural plans and details on Sheets A701, A702, and A703 indicate that the stairs and landings are wood framed construction and reference the structural drawings for their construction. Structural framing and details should be provided in the structural drawings. Note that Stairway C is open on at least one side and does not include a wall to support horizontal framing. Stringers should be designed considering an effective cross-section after notching and provided with sistered framing as needed to comply with strength and serviceability requirements. See IBC Sections 1015, 1603.1, 1604.1, and 1604.3. 7. The building includes guards at multiple locations including but not limited to the stairways and around floor openings overlooking lower levels. Details for guards should be included in the structural drawings. The guards should be designed for the loads per IBC Section 1607.8. Calculations substantiating the guard design should be submitted for review. See IBC Sections 1603.1 and 1604.1. Lateral System: 8. Detail 1/S301 specifies the typical sill plate anchorage. See IBC Section 107.2.1. The following comments should be addressed: a. The minimum concrete edge distance of 15x the anchor diameter (i.e., minimum 9.375-inch for 5/8-inch anchors) should be specified. Alternatively, calculations should be submitted for the design of the anchors per ACI-14 Section 17.2.3.5.2. See IBC Sections 1901.2 and 1905.1.8 Exception 1. b. The maximum six-foot spacing exceeds the spacings per the Shear Wall Schedule on Sheet S410. The detail should reference the schedule for the required spacings. 9. Details 1/S301 and 2/S301, and the Shear Wall Schedule on Sheet S410, include notes stating that post -installed (PI) anchor bolts may be substituted for the specified cast -in -place (CIP) anchors. The notes should be revised to state that this will require the revised anchor design to be submitted to the City for review and approval prior to construction. Alternatively, the alternative design for the PI anchors may be specified in the notes. In either case, documentation substantiating that the anchor design complies with ACI-14 Sections 17.2.3.3 and 17.2.3.5.2 must be submitted for review. See IBC Section 1901.2. 10. The Shear Wall Schedule on Sheet S410 specifies 0.148-inch diameter nails which corresponds to a 10d common nail; the shear capacities correspond to 10d nails. However, the 2.5-inch length corresponds to an 8d nail in both the common and box size. A minimum nail length of 3 inches should be specified to prevent use of the wrong fastener. The notes should also be revised. See IBC Section 2306.1 and AWC SDPWS-15 Table 4.3A. 11. Multiple shear walls at the second and third stories appear to be discontinuous and transfer holdown loads through supporting beams. Discontinuous walls include but are not limited to Girds D, E, F, and G at the second story, and Grid G at the third story. The beams are required to be designed for seismic loads including overstrength per ASCE 7-16 Section 12.3.3.3.
