S S • Architectural: 4. Handrails should be specified for all stairways. See IRC Section R311.7.8. 5. Guard details should be included in the construction drawings. 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. 6. The bedrooms should have emergency egress openings. The minimum opening dimensions and area, and maximum bottom sill opening height of the floor, should be specified. Structural modifications may be required. See IRC Section R310. 7. Smoke and CO alarms should be provided per IRC Sections R314 and R315. The locations of all alarms should be shown on the plans. The alarms should be hardwired, interconnected, and provided with back-up battery power as required. 8. Insulation should be specified for all exterior walls, floors, slab-on-grade, and ceiling/roof cavities per WSEC Table 402.1.1. 9. The project includes replacement of the existing windows and exterior doors. The required thermal ratings for each type of vertical fenestration should be specified. See WSEC Table R402.1.1. Structural: 10. The proposed project appears to include structural work. Structural drawings should be submitted as needed that include framing plans, sections, details, construction schedules, fastening schedules, materials requirements, general notes, special inspection requirements, etc. The drawings should substantiate compliance with the prescriptive requirements of the IRC. See IRC Sections R106.1.1 and R301.1. 11. The modified load paths should comply with the prescriptive limitations of the IRC. Alternatively, an engineered analysis and design may be performed per IRC Section R301.1.3; sealed and signed drawings and calculations prepared by a professional engineer licensed in the state of Washington are required per RCW 18.43.010, 18.43.020, and 18.43.070. The framing and foundation plans, and structural calculations as required, should show a complete load path. See IRC Section R301.1. 12. Details for the construction of the new walls should be included. The details should specify connections for the top and bottom framing plates to the existing structure. See IRC Sections R106.1.1 and R301.1. 13. The proposed design includes modifications to the existing wall bracing that do not comply with the requirement of IRC Section R602.10. The drawings should be revised. See IRC Section R106.1.3. 14. A fastener schedule should be provided per IRC Table R602.3(1). Providing a reference to this table in the drawings does not satisfy this requirement. In addition,the make and model of proprietary hardware should be specified in the plans and details where used for connections. 2
