Elden McCall Plan Check Number: B2207-083, B2207-086, B2207-089, B2207-090, B2207-091, and B2207-092, First Building Review September 27, 2022 Architectural 1. A handrail should be shown at the stairs on the floor plan in compliance with Section R311.7.8. 2. The plans should show a heat pump per the project energy credits. Plans currently show a furnace. WA State Energy Code Table R406.2 3. Smoke alarms on the second floor appear to be shown closer than 3 feet to the bathrooms. The smoke alarm should be relocated a minimum 3 feet from the bathroom door. See IRC Section R314.3 item 4 for more information. 4. See the selected energy credits on Sheet A7. The drawings should specify the maximum tested building air leakage per selected option 2.1. WSEC Table R406.3 5. See the selected energy credits on Sheet A7. The drawings should specify the minimum equipment efficiency per selected option 3.6. WSEC Table R406.3 6. See the selected energy credits on Sheet A7. The drawings should specify the minimum equipment efficiency per selected option 5.5. WSEC Table R406.3 Structural 1. The walls at the stairway appear to be up to 18 feet in height. The wall height exceeds the prescriptive limitation of the IRC and the shear walls at the location of the stairway do not meet the shear wall aspect ratio of 3.5 per Table 4.3.4 of the Special Design Provisions for Wind and Seismic (SDPWS). Shear walls should be updated and calculations substantiating the design should be submitted for review. R106.1.1, R602.3.1 2. Continuing with the previous comment, the walls at the stairway should be balloon framed from floor to roof to prevent a hinge at the 2nd floor level or provide a wind beam to resist horizontal wind loads acting on the wall. Submit calculations substantiating the design for review. R106.1.1, R602.3.1 3. It appears that some of the glulam beams are exposed to weather. Plans should specify the exposed glulam beams to be pressure treated with preservative or manufactured from naturally durable or preservative -treated wood. R317.1.5 4. Details for the deck guardrail should be provided. The guards should comply with IRC Section R312.1. The guards, connections to the supporting framing, and the supporting framing should be designed to resist a minimum 200-pound load per Table R301.5. 5. The structural calculations do not include calculations for the lateral design of the covered deck. Calculations substantiating the design should be submitted for review. Lateral loads should be transferred to the ground or to a structure capable of transmitting them to the ground. See Section R507.9.2 for more information.
