| 08/13/2020 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | Comment not addressed. [Initial comment: Calculate the number of required plumbing fixtures for the building addition. Note that based on the dimensions of the addition shown on sheet A-2, the gross area of the addition is greater than 2500 square feet. Reference: Section 2902.1, IBC 2018.] |
| 08/13/2020 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Reqs Change | 1. Comment not resolved: drawings unchanged. [Third comment: Comment not resolved: drawings unchanged.] [Second comment: Providing the extended operating capacity for the proposed heat pump rather than just the nominal cooling capacity clarifies the cooling capacity issue but the unit model number indicates that it is a cooling only unit with a 45KW heat strip (approximately 154 MBH, compared to the calculated 55 MBH heating load) which does not appear to be included in the electrical design. Show that power will be provided for the heat strip. [Initial comment: Provide justification for installing an HVAC unit having a total cooling capacity that far exceeds the total cooling load shown in the submitted calculations. Reference: Section C403.3.1, IECC 2018.] 2. Comment not resolved: drawings unchanged. [Third comment: Comment not resolved: drawings unchanged.] [Second comment: Show a design for the guards, including the method of attachment to the building, on the plans.] [Initial comment: Verify that the parapet height within ten feet of AC-1 is at least 42" above the walking surface of the roof or provide guards for the unit per Section 304.11, IMC 2018.] 3. Comment not resolved: drawings unchanged. [Third comment: Comment not resolved: drawings unchanged.] [Second comment: Condensate drains may not terminate over a roof drain or gutter unless the roof drain or gutter terminates at or below grade in an area capable of absorbing the condensate flow without surface drainage. Verify the termination of the roof drain.] [Initial comment: Show the size, routing, and termination of the condensate drain for AC-1. Reference: Section 307.2.1, IMC 2018 as amended by the City of Tucson.] 4. Comment not resolved: drawings unchanged. [Third comment: Comment not resolved: drawings unchanged.] [Second comment: Comment not addressed; provide the sequence of operation for the restroom exhaust fans.] [Initial comment: Provide information on the sequence of operation for the restroom exhaust fans to show that all of the air supplied to the restrooms will be exhausted. The exhausted air from the restrooms shall be limited to no more than 10% of any subsequent supply air stream. Reference: Section 403.2.1 (4), IMC 2018.] 5. Comment not resolved: drawings unchanged. [Third comment: Comment not resolved: drawings unchanged.] [Second comment: Comment not resolved. Verify the occupancy types, areas for each occupancy type, and the supply air flowrates. Check addition. The occupant load is based on Table 403.3.1.1, IMC 2018.] [Initial comment: Calculation of the required minimum ventilation for air handlers serving multiple zones requires the balancing data (supply CFM) for each zone and the calculations described in Sections 403.3.1.1.2.3.1 through 403.3.1.1.2.3.4, IMC 2018. Reference: Section 403.3.1.1.2.3, IMC 2018.] 6. Comment not resolved: drawings unchanged. [Initial comment: Provide a smoke detector in the return air duct, upstream of any outside air connections, for AC-1. Reference: Section 606.2.1, IMC 2018, as amended by the City of Tucson.] |
