STRUCTURAL REVIEW COMMENTS: N/A BUILDING REVIEW COMMENTS: N/A MECHANICAL REVIEW COMMENTS: Denied Comment Mechanical 3: “Not compiled, recirculating hood is not acceptable and must have exhaust to the outdoors per Chapter 4, ‘Not Compiled,’ there is no radiation damper tested and listed for kitchen exhaust applications.” Response: IMC 506.3.11 prohibits fire dampers from being installed in grease duct. Grease duct is only required at Type I hoods, which we do not have. Domestic kitchen exhaust ducts are covered in IMC 505.3, and there are no adiation damper restrictions in this section of code. Not Complied this code section you have stated is a misapplication of the code. It does not apply to residential kitchens, it applies to commercial kitchen applications. Response to Comment Mechanical 3: Per correspondence with Juan Garcia III: “A recirculating kitchen hood employed with a ceiling exhaust fan in the kitchen area per exception 1, Section 505.3, IMC 2018 to resolve this item. The ceiling fan will provide the local exhaust required by Section 403.3.3.2, IMC 2018 (100 CFM intermittent or 25 CFM continuous) and can be equipped with a radiation damper.” A recirculating kitchen hood employed with a ceiling exhaust fan capable of exhausting 100 CFM of air intermittently in the kitchen area was added. See Sheets M003, M421, M422, M423, A641, A642, E008, E421, E422, and E423. Complied Comment Mechanical 8.1: “A corridor damper shall be installed in corridor ceiling enclosure on all floors on Sheet M101 (IMC2018,607.5.4).” Response: Plans have been updated to reflect this. Not Complied your updated plans does not clarify corridor dampers at the ceiling diffusers. You have a number 6 next to cd but in keynote does not describe what the note 6 is next to the diffusers. Response to Comment Mechanical 8.1: Per correspondence with Juan Garcia III: “This item was resolved. The Legend on Sheet M002 of the last submittal clearly shows the symbols for a corridor damper and for a radiation damper.” Please note that Number 6 on Sheet M101 is the delta revision number. Complied Comment Mechanical 8.2: “Provide corridor dampers where ducts penetrate corridor ceiling enclosure throughout on first floor on Sheet M201 (IMC2018,607.5.4).” Response: Plans have been updated to reflect this. Note that some of the ductwork and diffusers shown on M201 are below the rated floor/ceiling assembly. These are not provided with radiation or corridor dampers. Understood but you need to note that information on the sheets that the ceiling fire rated assembly is not penetrated in the corridors and provide a note for the corridor dampers required when penetrated you have not done that, it needs to be clear, therefore until corrected it is Not Complied. Response to Comment Mechanical 8.2: Per correspondence with Juan Garcia III: “Provide notation to clarify the location of the ducts relative to the rated horizontal assembly to resolve this item.” Added Keynotes 10 and 11 on Sheet M201 that clarify which ducts are routed above or below the rated floor/ceiling assembly. Complied Comment Mechanical 8.3: “Elevator machine rooms, machinery spaces that contain the driving machine, and control rooms or spaces that contain the operation or motion controller for elevator operation shall be provided with an independent ventilation or air conditioning system to protect against the overheating of the electrical equipment. Show where you are providing this (IBC2018,005.2).” Response: RTU-3 and -4 are ducted into the elevator shafts to protect against overheating; see Sheet M121. Not Complied mechanical systems are not allowed in elevator shafts (IMC2018,303.8). Response to Comment Mechanical 8.3: Per correspondence with Juan Garcia III: “Please provide the manufacturer’s information and specifications for cooling of equipment for review.” Attached is rooftop unit (RTU) cutsheet for the Basis of Design, Model 48VL-C24040. Not Complied the code section is clear a mechanical system is not allowed in shaft ELECTRICAL REVIEW COMMENTS N/A PLUMBING REVIEW COMMENTS: N/A If you require additional clarification regarding these comments, please contact Doris Benoit at doris.benoit@tucsonaz.gov |
