| 01/25/2016 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Reqs Change | 1. Exhaust fan EF-5 has been added to the mechanical design on sheet M101 to provide exhaust during a CO2 emergency but the fan has not been specified and no sequence of operation has been provided. [Second comment: A 200-pound liquid cryogenic tank (dewar) for CO2 is shown on sheet K402. Provide a mechanical exhaust system activated by an asphyxiant gas detection system. The alarm system itself will be handled as a separate permit from the Tucson Fire Department.] [Initial comment: If the carbon dioxide storage consists of more than two 50-pound cylinders, provide a mechanical exhaust system activated by an asphyxiant gas detection system. Reference: Tucson Fire Department Standard Operating Guideline for Compressed Gases dated 04/28/2015.] 2. The comment responses indicated that a ventilation schedule had been added to sheet M202 but no such schedule was found on the version of sheet M202 that was submitted. [Second comment: Provide the room areas used to determine the occupant load for the ventilation calculations.] [Initial comment: The occupant load used to calculate the required ventilation is not necessarily the same as the occupant load used for calculating exiting requirements. The occupant load used for calculating the minimum required ventilation is to be based on Table 403.3, IMC 2012 or an approved engineering analysis of the specific occupancy type. Reference: Section 403.3, IMC 2012.] |
| 01/25/2016 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | The specified temperature mixing valve, Powers LFe480, is listed to ASSE 1070 and does not have any manufacturer's application warnings with regard to location or recirculation systems. However, the pressure drop across the valve is 45 PSI with a flow of 4 GPM. The connected hot water load appears to be approximately 22 GPM, consisting of 6 hand sinks, 2 lavatories, 2 3-compartment sinks, a pre-rinse faucet, a mop sink, and a re-thermalizer. Show how the fixtures are to be supplied with a minimum flow pressure of 15 PSI. Reference: Section 604.3, IPC 2012, as amended by the City of Tucson. [Second comment: The revised mixing valve, Powers model LFLM495, is listed to ASSE 1070 but the manufacturer's specification sheet warns that the valve is not to be used at the source of the hot water when an ASSE 1070-listed mixing valve is required. Further, the manufacturer states that the valve is not to be used at the hot water source in recirculation systems. Reference: Section 303.2, IPC 2012.] [Initial comment: The specified temperature mixing valve (Powers LM490) is listed as conforming to ASSE 1017, not ASSE 1070. Provide tempered water for the restroom lavatories using approved devices conforming to ASSE 1070. Reference: Section 607.1.2, IPC 2012.] |
