5. The proposed project appears to involve work that is not clearly shown including but not limited to modifying walls, doors, floors, roof, windows, sinks, showers, and toilets. All proposed work should be clearly shown in the drawings. The drawings should clearly delineate between existing and new work using established drafting standards. All demolition should be shown on the existing floor plans. All new construction should be shown on the new floor plan. Where the proposed project includes modifications to existing building components (e.g., gypsum wall board, insulation, etc.), these components should be similarly delineated from existing component that are not being altered. See IRC Section R106.1.1. Architectural: 6. Handrails should be specified for all stairways. See IRC Section R311.7.8. 7. 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. 8. 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. 9. Insulation should be specified for all exterior walls, floors, slab-on-grade, and ceiling/roof cavities per WSEC Table 402.1.1. 10. 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. 11. The project may involve increasing the conditioned space at the upper floor. Energy credits are required per WSEC Section R406. The required number of credits should be normalized per Table R406.2. A schedule of the selected credits should be included in the drawings. The performance requirements for the selected credits should be specified. 12. The bathrooms and kitchen should specify exhaust fans including the minimum required performance rates per IRC Table M1505.4.4(1). Structural: 13. The proposed project may 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. 14. Continuing with the previous comment, 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.
