Botesch, Nash & Hall <br /> Architects, P.S. <br /> June 14, 2016 <br /> Steve Miller <br /> City of Everett <br /> RE: Puget Sound Kidney Center: #B1605-059 <br /> Comment ID # 1 It appears that the construction type could be reclassified to type V- <br /> B. If not, rated assemblies must be provided for floor/ceilings, roof, and bearing walls. <br /> Also detailing of the protection of any penetrations of these assemblies. If reclassifying <br /> is possible, please provide the analysis on the cover sheet. <br /> See sheet G1.0. The construction type has been changed to VB. The analysis of <br /> allowable floors and area, per IBC chapter 5, has also been added. <br /> Comment ID # 2 Using an occupant load factor of 100 per square foot of gross floor <br /> area as required by IBC 1004 results in an occupant load of 74 or 77 per floor. With half <br /> of the occupants per floor using each exit, IBC 118 requires one-hour rated corridors <br /> where the occupant load exceeds 30. <br /> See sheet G1.1. On the first floor, the actual occupants are listed to show an <br /> occupant load under 30. On the second floor, a 1-hour rated corridor is shown. <br /> See sheet A1.2. Door 226A has been added to create the 1-hour rated corridor. <br /> See sheet A9.1. The door schedule has been updated to include 20 min. rated <br /> doors in the 1-hour rated corridor walls. <br /> See sheets M1.2, M5.2, M5.4. The HVAC ductwork has been reworked to avoid <br /> any penetrations in the 1-hour rated corridor walls. <br /> See sheets E2.3, E4.3. The electrical has been redone for the new HVAC. <br /> Comment ID # 3 IBC 1503.4 requires emergency overflow at the new roof drains. <br /> See sheet A3.0. The emergency overflows have been shown with keynote 3.11. <br /> See sheet A8.1. The emergency overflow has been added to detail 8. <br /> „,r <br />
