01/27/2014 RBROWN1 WATER REVIEW Denied Clarify the intent of the modifications to the water service for Suite 101. Keynote # 4 on C/P2.0 indicates that a new "1" water meter and a 1-1/4" backflow preventer" will be installed to serve the restroom and kitchen. Is this new water meter intended to be a sub-meter or a replacement of the existing meter supplied by Tucson Water? If not a sub-meter, all water meters for Tucson Water shall be located at the property line at a location accessible to Tucson Water. Show the location and size of the existing water service meter and backflow device on the site plan.
01/28/2014 ROBERT SHERRY PLUMBING-COMMERCIAL REVIEW Denied 1. Backflow preventers are required to be located in accessible locations and per the manufacturer's installation instructions; a location above a ceiling is not accessible. Reference: Section 608.14, IPC 2012.
2. Verify that the tempered water for the lavatories and public hand-washing sinks in restrooms is provided using approved devices conforming to ASSE 1070. The specified Leonard and Lawler mixing valves, for example, are not listed as meeting the requirements of ASSE 1070. Reference: Sections 416.5 and 607.1.2, IPC 2012.
3. Provide calculations showing how the water supply piping has been sized. Reference: Sections 604.1 and 604.3, IPC 2012.
4. Provide a full-open valve for the water service at the building entrance. Reference: Section 606.1(2), IPC 2012.
5. Provide the rim elevation of the next upstream sanitary manhole and the first floor elevation. Determine the need for a backwater valve per Section 715.1, IPC 2012, as amended by the City of Tucson.
6. Provide separate indirect waste pipes for each compartment of the 3-compartment sink to protect against cross-contamination or fouling. Reference: Sections 801.2 and 802.1.8, IPC 2012.
7. Indirect waste piping that has a developed length greater than 30-inches (30") when measured horizontally or greater than 54-inches (54") in total developed length shall be trapped. Exception: indirect waste piping conveying only clear-water waste (e.g. effluent from a sanitizing compartment) does not require a trap. Reference: Section 802.2, IPC 2012.
8. Provide a detail showing that the installation of the open hub drain meets the requirements of Section 802.3.2, IPC 2012 for the height of the hub rim above the floor and how the floor is to be made impervious to water.
9. Verify that the Pima County Regional Wastewater Reclamation Department will allow the drains from the janitor's sink and the hand sinks to bypass the grease interceptor. Reference: Section 1003.3, IPC 2012, as amended by the City of Tucson.
10. A dishwasher may not discharge through a hydromechanical grease interceptor. Verify how the discharge from the dishwasher can be accommodated with the Pima County Regional Wastewater Reclamation Department. Reference: Section 1003.3, IPC 2012, as amended by the City of Tucson.
11. Provide a vent downstream of the grease separator to protect the seal for the grease separator. Reference: Section 1003.9, IPC 2012.
12. If the specified water heater is not supplied with integral heat traps, provide heat traps on the supply and discharge piping. Reference: Section C404.4, IECC 2012.
13. If the specified water heater is not supplied with integral heat traps, provide 0.5" of insulation with a maximum conductivity of 0.27 BTU per inch/h F on the first 8 feet of supply and discharge piping. Reference: Section C404.5, IECC 2012.
14. Provide the total developed pipe length to each appliance supplied with natural gas. Reference: Section 402.3, IFGC 2012.
15. Clarify the connected loads or input ratings for each appliance (e.g. does the fryer have one connection at 230 CFH or two connections at 115 CFH?). State the minimum gas pressure required for each appliance by the appliance manufacturer. Reference: Section 402.1, IFGC 2012.
16. Coordinate the plumbing, water, and gas plan with detail 4/P3.0; the size of the gas pipe serving the ovens is 2" on the detail but only 1" on the gas plan. Reference: Section 107.2.1, IBC 2012.
17. Clarify the pizza oven configuration; it is scheduled as a double oven with two gas connections but is shown as a triple oven in elevation E/A5.1. Reference: Section 107.2.1, IBC 2012.
01/28/2014 RONALD BROWN MECHANICAL-COMMERCIAL REVIEW Denied 1. Provide structural calculations to verify that the existing roof is capable of supporting the additional dead load due to the installation of the roof top unit RTU-3. Reference: Section 302.1, IMC 2012.
2. Provide structural calculations and details to show that the Type I hood is supported from the building structure in accordance with Section 507.6, IMC 2012 (the hood hanging weight plus the weight of personnel working in or on the hood). Reference: Section 302.1, IMC 2012.
3. Based on a return temperature of 78 degrees Fahrenheit and an outside air temperature of 104 degrees Fahrenheit, the mixed air temperature entering the evaporator coils of both RTU-2 and RTU-3 will be above 90 degrees Fahrenheit (91ºF for RTU-2 and 95ºF for RTU-3). Contact the manufacturers of the two units to verify the ability of the units to function in this environment. Reference: Section 304.1, IMC 2012.
4. Provide guards for equipment located within 10 feet of a roof edge (e.g. exhaust fans or condensing units located within ten feet of the east edge of the roof). Reference: Section 304.11, IMC 2012.
5. Condensate drains may not terminate in an area that is not capable of absorbing the condensate flow without surface drainage. Terminating the condensate drain of a rooftop unit (e.g. detail 6/P3.0) is not acceptable. Reference: Section 307.2.1, IMC 2012, as amended by the City of Tucson.
6. Revise the sequence of operation for the restroom exhaust fan (EF-4) so that all of the air supplied to the restroom will be exhausted (i.e. the exhaust fan shall run as long as RTU-2 supplies air into the restroom). Reference: Section 403.2.1 (4), IMC 2012.
7. Clarify the size of the dishwashing hood; on sheet M1.0 it is 3'-3" long but on sheet M4.0 it is 5'-0" long. Reference: Section 107.2.1, IBC 2012.
8. Specify the insulation to be installed around the grease ducts as indicated in keynote #1 on sheet M1.0. Reference: Section 506.3.11.2, IMC 2012.
