� • <br /> supporting structure of the one-hour fire-resistant assembly is provided with equal or <br /> greater fire-resistance rating. Identify all supporting structures on plans. <br /> R302.3 Two-family dwellings. <br /> Dwelling units in two-family dwellings shall be separated from each other by wall and/or <br /> floor assemblies having not less than a 1-hour fire-resistance rating when tested in <br /> accordance with ASTM E 119 or UL 263. Fire-resistance-rated floor/ceiling and wall <br /> assemblies shall extend to and be tight against the exterior wall, and wall assemblies shall <br /> extend from the foundation to the underside of the roof sheathing. <br /> R302.3.1 Supporting construction. <br /> When floor assemblies are required to be fire-resistance rated by Section R302.3, the <br /> supporting construction of such assemblies shall have an equal or greater fire-resistance <br /> rating. <br /> 5. The section designation (Detail B, Sheet 5) on sheet one, is located where the <br /> foundation for the fireplace is shown on the Basement Plan (called out as existing <br /> chimney) and Main Floor Plan. How is the foundation for the fireplace and the chimney <br /> supported where the floor in the basement is lowered? Provide detail(s). <br /> 6. Detail B on sheet 5 ��Building Section" does not provide sufficient detail to review the <br /> new construction for resistance to seismic loads, lateral loads and surcharge form the <br /> ground loads. Provide detail that includes all dimensions and reinforcing required to <br /> resist all loads specified in the International Residential Code. Details shall be prepared <br /> by a licensed WA State Structural Engineer and shall be designed for different heights as <br /> needed by site conditions. <br /> 7. Provide detail/section at rear of house where daylight condition exists. Show how <br /> ground level at the rear of the house is graded to allow entry to the basement. Provide <br /> minimum 36" landing at exterior entrance/exit. Show on plans. <br /> 8. The post at the north end of beam #4 in bedroom #2 is located in the same space <br /> occupied by the foundation of the fireplace. Please clarify the condition at this location. <br /> 9. Several beams in the gravity calculations submitted are a different length on the plan <br /> than what is shown in the calculations. Several beams in the framing plan were not <br /> included in the gravity calculations submitted. <br /> 10. Provide section drawing of framed walls on interior of concrete walls at existing floor <br /> joists in both parallel and perpendicular conditions. Show fireblocking and one-hour fire- <br /> resistive assembly. <br /> � � , <br /> � <br /> S:\1Common\Clerical\JHeilman\C1604-008(3316 HOYT AVE).doc <br />
