Fire Damage Repair <br /> Project Address: 2415 11th Street <br /> Dear Mr. Lee, <br /> Itemized below is our response to the review comments in the September 13, 2017 corrections letter for the <br /> above referenced project. Our response appears in bold. <br /> 1. A listing for the one-hour walls should be provided. IEBC Section 603.1. <br /> IEBC 603.1 commentary says,"...provide the same level of coverage and protection that existed <br /> prior to the repairs being undertaken." We have added notes to that effect to the plan sheets <br /> S2.1 and S2.2. Since the gypsum board has already been removed in the affected units,we added <br /> a plan note that all assemblies shall have a minimum of 5/8"gypsum board. <br /> 2. A listing for the one-hour floor/ceiling assembly between the upper and lower floors should be <br /> provided. IEBC Section 603.1. <br /> See item 1 response. <br /> 3. Duct penetrations through a one-hour floor/ceiling assembly should be provided with ceiling <br /> radiation dampers or a shaft. IBC Section 717.6.2. <br /> There is no through-floor ductwork existing or proposed. <br /> 4. A manual fire alarm system should be provided for the building if the project does not fall under an <br /> exception provided under IFC Section 1103.7.6. <br /> There is already an existing manual fire alarm system in this building. <br /> 5. The locations of smoke alarms within the repaired units should be shown on the plans.The alarms <br /> should be hardwired, interconnected and provided with battery backup. IFC Section 1103.8. <br /> Smoke alarm locations have been added to the plans on sheet S2.1 and S2.2. <br /> 6. Carbon Monoxide alarms should be shown on the plans. IFC Section 1103.9. <br /> Carbon monoxide alarms have been added to plan sheets S2.1 and S2.2. <br /> D EC- E5VED (1 ) <br /> ^^ ,p <br /> IFN <br /> SEP 2 0 2017 <br /> 250 4th Avenue South,Suite 200 <br /> CITY OF EVERETT Edmonds,WA 98020 <br /> Permit Services ph.425.778.8500 I f.425.778.5536 <br /> www.cgengineering.com <br />
