| 04/20/2016 | ERIC NEWCOMB | BUILDING-COMMERCIAL | REVIEW | Reqs Change | 1. GENERAL: IT APPEARS MANY OF THE COMMENTS IN THE PREVIOUS REVIEW WERE NOT PICKED UP IN THIS SUBMITTAL. PLEASE REVIEW AND REVISE. 2. GENERAL: THE METAL BUILDING SHOP DRAWINGS AND STRUCTURAL CALCULATIONS MAY NOT BE SUBMITTED UNTIL THE ORIGINAL SUBMITTAL DRAWINGS ARE APPROVED. 3. GENERAL: PLEASE PROVIDE WRITTEN RESPONSES TO ALL REVIEW COMMENTS, INCLUDING THOSE FROM THE PREVIOUS REVIEW. |
| 04/25/2016 | ROBERT SHERRY | WATER | REVIEW | Reqs Change | Provide the total demand that this water meter will serve; the Tucson Water records indicate that the meter is already serving an existing building. [Initial comment: Provide the size of the water meter serving this building, the size of the backflow preventer associated with the water meter, and the total water demand served by the water meter. Provide the serial number for the meter. Reference: Section 107.2.1, IBC 2012.] |
| 04/26/2016 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Reqs Change | 1. The cover sheet still shows an E occupancy and no plumbing fixture calculations have been provided. [Initial comment: Clarify if this building will be classified as an assembly or an educational occupancy. Provide the minimum plumbing facilities required by Table 2902.1 and Section 2902.2, IBC 2012.] 2. Comment not addressed. [Initial comment: Clarify the part of the description of the urinal that refers to a "high rim". Show the mounting height dimensions for the urinals on sheet A-4. Reference: Section 1109.2 (6), IBC 2012.] 3. With the revised developed pipe length of 178 feet and using Table 402.4 (2), IFGC 2012, the sizes of two sections of pipe will need to be increased. The section of pipe between the two ovens should be 1" and the branch serving the range should be 1-1/2". [Initial comment: Verify the developed pipe length for the gas piping. The site plan shows the gas meter over 130-feet from the exterior of the new building. Reference: Sections 402.1 and 402.3, IFGC 2012.] 4. In the water heater detail on sheet P-3, relocate the shut off valve for the gas supply so that the sediment trap is downstream of the valve. [Initial comment: If the manufacturer does not incorporate a sediment trap within the gas-fired equipment, provide a sediment trap downstream of the appliance shut off valve, as close to the equipment as possible. Reference: Section 408.4, IFGC 2012.] 5. The water heater detail on sheet P-3 shows a natural draft flue for the water heater. Provide combustion air for the water heater. Reference: Section 304.1, IFGC 2012. [Initial comment: Specify the type of venting system and the venting materials to be used for the proposed water heater. Reference: Section 503.1, IFGC 2012.] 6. Revise the water heater detail by: removing the shut off valve at the expansion tank; remove the second shut off valve between the expansion tank and the water heater; clarify the gas input to the water heater (199 CFH or 50 CFH); and show the note for the T&P relief that was cut off from the detail. [Initial comment: Provide a detail of the water heater installation, including the excess pressure relief, expansion tank, safety pan, recirculation pump, and valves. Reference: Sections 503, 504, 606.1, 607.2, and 607.3, IPC 2012.] 7. The developed length of hot water piping exceeds 50-feet from the water heater to the furthest hot water outlet so a recirculating system (or some other method of effectively reducing the distance from the hot water source to the furthest hot water outlet) is needed. Reference: Section 607.2, IPC 2012. [Initial comment: Show the return piping for the recirculated hot water for the water heater on the plans and detail. Reference: Section 107.2.1, IBC 2012.] 8. Comment not resolved. [Initial comment: Provide automatic or manual controls for the circulating hot water system per Section C404.6, IECC 2012.] 9. A water pressure in excess of 80 PSI requires the installation of a water pressure reducing valve (Section 604.8, IPC 2012). The static lift is equal to the vertical distance between the outlet of the water meter and the highest water outlet (e.g. a lavatory of sink faucet). The pressure drop across a reduced pressure backflow preventer is greater than 5 PSI - see a specification sheet for a reduced pressure backflow preventer such as a Watt's LF009 as an example (http://media.wattswater.com/ES-LF009.pdf). [Initial comment: Clarify how the water service and distribution piping has been sized. It appears that the sizing method presented in Section E201, IPC 2012 has been used but there is insufficient data (e.g. minimum daily service pressure, required static lift, pressure losses due to special equipment, and the minimum pressure at each fixture) presented to confirm the pipe sizes. Reference: Section 604.3 (as amended by the City of Tucson) and E201.1, IPC 2012.] 10. Verify the existing material can be located below a building. [Initial comment: Show the inverts and slope of the existing 6" building sewer line on the drawing. Verify the existing material can be located below a building. Verify that the building sewer is not in conflict with the proposed building foundation. Reference: Section 107.2.1, IBC 2012 and Table 702.2, IPC 2012.] 11. The minimum size for a hydromechanical grease interceptor is 25 GPM and 50 pounds of grease capacity; you specify two different sizes on sheets P-2 and P-4. Show how access will be provided to the flow control device. Reference: Section 1003.3, IPC 2012 as amended by the City of Tucson. [Initial comment: The specified hydromechanical grease interceptor (Zurn Z1170) requires the installation of an external flow control device. Show how this device is to be installed per the manufacturer's instructions. Reference: Sections 303.2 and 1003.3.4.2, IPC 2012.] |
| 04/26/2016 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Reqs Change | 1. Clarify how the continuous insulation is to be provided for the roof and three of the four exterior walls. Provide documentation for the U-value used for door types B, C, and E. [Initial comment: Revise the energy code analysis for the building envelope, coordinating the building components used in the analysis with those shown on the drawing. Reference: Section C303.1, IECC 2012, as amended by the City of Tucson.] 2. Provide a statement on the drawings that the U-values and SHGC values are the maximum acceptable numbers and that the submitted components shall be NFRC-certified. [Initial comment: Provide NFRC fenestration product ratings for the U-factor and the SHGC values on COMcheck or use the appropriate default U-factor and SHGC values from Tables C303.1.3 (1), C303.1.3 (2) and C303.1.3.(3), IECC 2012. Reference: Section C303.1.3, IECC 2012.] 3. Comment not resolved; it is unclear to which area of the building and which of the specified heating and cooling units each calculation applies. [Initial comment: Revise the heating and cooling load calculations; clarify to which area of the building and which of the specified heating and cooling units each calculation applies. Reference: Sections C403.2.1 and C403.2.2, IECC 2012, and Section 312.1, IMC 2012.] 4. Provide manufacturer's specifications for the split-system heat pumps that are to be installed. [Initial comment: Full compliance with the 2012 IECC requires that an "additional efficiency package option" be selected per Section C406. The high efficiency HVAC option was chosen but none of the specified HVAC units comply with the requirements. The mechanical compliance certificate shows eight packaged terminal heat pumps with a capacity of 7 k BTUH cooling capacity being installed but the drawings show seven packaged heat pumps with a cooling capacity of 72 k BTUH and one packaged heat pump with a cooling capacity of 30 k BTUH; see Tables C403.2.3 (2) and C406.2 (2), IECC 2012.] 5. Verify the areas used to calculate the ventilation requirements for the dining area of the building. [Initial comment: Revise the ventilation table shown on sheet M-2 to agree with the ventilation calculations submitted with the COMcheck reports. Reference: Section 403.3, IMC 2012.] 6. Indicate the size of the exhaust ducts and the manner in which they are to be terminated. [Initial comment: Provide specifications for the exhaust fans serving the restrooms and the janitor's room. Indicate how they are to be installed, controlled, the size of the exhaust ducts, and the manner in which they are to be terminated. Reference: Section 107.2.1, IBC 2012.] 7. Manufacturer's shop drawings do not constitute an acceptable design. Provide a design showing what is being installed and how it complies with the mechanical code. Reference: Chapter 5, IMC 2012. [Initial comment: Provide a complete design for the Type I grease hood system, including the hood, grease ducts, exhaust fans, and make-up air units. Materials of construction, structural connections, controls, and balancing data shall be included. If the Type I hood is being relocated, verify that the manufacturer's listing is still in effect. Reference: Sections 301.7, 506, 507, and 508, IMC 2012.] |
