| 05/25/2021 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | 1. The required expansion tank has been removed. Correct the detail. [Initial comment: Correct the connection entry for the expansion tank in the plumbing equipment/fixture schedule to show the expansion tank connected to the cold water rather than the hot water. Reference: Section 303.2, IPC 2018.] 2. Comment not addressed. [Initial comment: Provide tempered water for the restroom lavatories using approved devices conforming to ASSE 1070. Reference: Sections 419.5 and 607.1.2, IPC 2018.] 3. Comment not addressed. [Initial comment: Provide an approved vacuum relief valve for the scheduled bottom-fed water heater that is located above the fixture outlets. Reference: Section 504.2, IPC 2018.] 4. Comment not addressed. [Initial comment: Provide calculations showing how the water supply piping has been sized. Reference: Sections 604.1 and 604.3, IPC 2018.] 5. Comment not addressed. [Initial comment: Verify that the pipe sizes called out for the flush valves will not result in water velocities greater than that recommended by the pipe manufacturer (e.g. limit the water velocity to less than 8 FPS for copper, PEX, or CPVC piping). At a minimum design flow rate of 25 GPM for a siphonic, flush-valve water closet, a 1” Type L copper pipe has a flow velocity of 9.7 FPS. Reference: Table 604.3, IPC 2018.] 6. Show the locations of the specified tankless water heaters. [Initial comment: Show that the distance from the hot water source to the hot water termination for the public lavatories complies with the requirements of Section C404.5, IECC 2018.] 7. The 2 PSIG gas piping will require regulators at each appliance. Show the sediment traps. Reference: Section 408.4, IFGC 2018. [Initial comment: Southwest Gas, the local gas utility, provides natural gas at 7” WG, 2 PSIG, and 5 PSIG. Appliances needing gas service at 7” WG or greater will require a gas meter that delivers at least 2 PSIG gas into a regulator located after the meter set. Reference: Section 402.1, IFGC 2018.] |
| 05/25/2021 | ROBERT SHERRY | WATER | REVIEW | Reqs Change | 1. Comment not addressed. [Initial comment: Show the size and location of the proposed water meter, backflow preventer, and the water service pipe on a site plan. The development package is not a substitute for a complete site plan. Reference: Section 107.2.1 and 107.2.6, IBC 2018.] 2. Comment not addressed. [Initial comment: Verify the calculated water demand (216.1 GPM, sheet P1). Reference: Section 107.2.1, IBC 2018.] 3. Comment not addressed. [Initial comment: Reduced pressure backflow prevention assemblies are required to be installed in locations accessible to Tucson Water. Reference: Chapter XXVII, Article V, Section 27-72, the Tucson Code, http://www.tucsonaz.gov/files/water/docs/backflow-ordinance.pdf] |
| 05/26/2021 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Reqs Change | 1. The unit heater vents are still shown as being horizontal. [Initial comment: Clarify how the unit heater flues are to be installed (e.g. flue material, slope direction, thimble requirement, condensate drain, minimum flue extension beyond the exterior wall, termination type, etc.). Reference: Section 305.1, IFGC 2018.] 2. All unit heater vents are still shown as horizontal, the furnace vent route and termination is not shown. [Initial comment: Three of the flues terminate over doorways; show how the condensate will be prevented from becoming a nuisance or hazard. Reference: Section 503.8 (4), IFGC 2018.] 3. Comment not addressed; only the COMcheck mechanical compliance report was submitted. [Initial comment: Demonstrate energy code compliance for the building envelope using calculations based on the current code. Reference: Sections C101.5, C103.2, C303, and C401.2, International Energy Conservation Code 2018.] 4. Revise the COMcheck mechanical report using the equipment types specified in the plans (e.g. the evaporative coolers are not “evaporatively cooled condensers”) [Initial comment: Show how one of the “Additional Efficiency Package Options” (C406, IECC 2018) is to be accomplished. Reference: Section C401.2, IECC 2018.] 5. Provide calculations and equipment selection based on the current activity. Correct errors in equipment schedule (e.g. condensing unit weighs 150 pounds, not 30 pounds; “VAV w/ baseboard heating”). [Initial comment: Provide heating and cooling load calculations to justify the heating/cooling capacities of the specified HVAC unit for the offices and restroom. Reference: Section C403.1.1 and C403.3.1, IECC 2018.] 6. Show that the cooling capacity of the matched condenser/evaporator coils does not exceed the calculated cooling load by more than 6,000 BTUH. [Initial comment: Show that the proposed HVAC equipment for the offices and restroom meets the minimum performance requirements of Section C403.3.2, IECC 2018.] 7. Provide calculations based on the 2018 IMC. [Initial comment: Provide calculations to verify that adequate ventilation will be provided for the offices and restroom. Reference: Section 403.3.1.1, IMC 2018.] 8. Provide calculations based on the 2018 IMC. Clarify the “existing rooftop unit” noted in the calculations. [Initial comment: Provide calculations to show how natural ventilation has been provided for the warehouse. Reference: Section 402.2, IMC 2018.] 9. EF-1 shall provide the required exhaust airflow rate during the hours of operation even when the lights are off. [Initial comment: Provide information on the sequence of operation for the restroom exhaust fan, EF-1, 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.] |
| 06/03/2021 | ERIC NEWCOMB | BUILDING-COMMERCIAL | REVIEW | Approved | |
| 06/14/2021 | DAN SANTA CRUZ | ELECTRICAL-COMMERCIAL | REVIEW | Reqs Change | Please address the following electrical plan review comments. Also provide a written response. The revised outdoor lighting calculations are not sufficient to verify complete compliance with the Outdoor Lighting Code. See section 104, (Plan, Permit Submittal requirements). #1. The following errors were found in the Outdoor Lighting Calculations. (a)Verify the correct parcel size in acres. (b) Show total allowed lumens vs total proposed lumens. Include all luminaires, new and existing. (c)Indicate shielding and lamp output color temperature output (not to exceed 3500K per OLC section 402.1). #2. Ref; Plan Sheet E6, E7A. The line diagrams for the Electrical Services are not the same Equipment. Please clarify. Provide a grounding detail for whichever is the correct Service Equipment. Ref; 2018 IBC sec 107.2.1, 2017 NEC, 2012 Tucson/Pima County Outdoor Lighting Code (OLC), City of Tucson Commercial Plan Submittal Requirements |
