10/09/2018 DAN SANTA CRUZ ELECTRICAL-COMMERCIAL REVIEW Reqs Change Please address the following electrical plan review comments. Also provide a written response.
#1. Ref; Plan Sheet E1.
(a) The two sets of 500Kcmil Al feeders for panel 'H2' are undersized for the 800 amp OCPD's. The parallel 500's have a ampere rating of 620 amps at 75deg. NEC 240.4, 310.15B(16).
(b) Indicate the voltage and amp rating of the main service disconnecting means.
(c) The 3/0 cu feeders between panels 'H' and 'H2' are undersized for the 225 amp OCPD in panel 'H'. Should be 4/0 cu or 300Kcmil AL. NEC 240.4, 310.15B(16).
(d) The one -line diagram shows transformers 'T1' and 'T2' being fed from panel 'H'. 'T2' is shown on the panel schedule for panel 'H2'. Also the feeder sizes shown on the panel schedules do not correlate with the conduit and feeder schedule. Please clarify.
#2. Ref; Plan Sheets E1 and E2.
(a) Grounding Detail shown for the transformers on plan sheet E3 seems to apply to services. Also some of the code references were deleted or revised from 1996. Please revise the transformer grounding detail to correlate with the 2011 NEC art 250.30. Size the GEC for the derived secondary conductors. 250.30A (1thru 5) NEC.
(b) Provide secondary fused disconnect switches as required per NEC 240.4, 240.21, 450.3, 450.14.
(c) The feeder size shown on the panel schedule 'L' for panel 'A4' (#2 wire) does not correlate with the conduit and wire schedule (3/0). Please clarify.
#3. Ref; Plan Sheet E3.
Provide for GFI protection of the restroom receptacles and any receptacles within 6' of a sink. Rooms # 227.
#4. Ref; Plan Sheets E7 and E8.
Provide an identifying mark or symbol for each exterior luminaire on the parcel, including existing parking lot lighting. These luminaires must be shown at their location on the property and correlate with the luminaire schedule and Outdoor lighting calcs. Indicate which option is used per table 401.1 OLC. Be advised that "Option 1" (350,000) of area "E3", is for LPS lighting.
#5. No compliance with the previous plan review comment #1(h).
Ref; 2012 IBC sec 107.2.1, 2011 NEC, Tucson/Pima County Outdoor Lighting code (OLC).
10/16/2018 ROBERT SHERRY MECHANICAL-COMMERCIAL REVIEW Reqs Change 1. Comment not resolved. Provide balancing information for each area and identify the symbols used for the HVAC system components (e.g. supply/return/exhaust devices). [Initial comment: Provide construction documents drawn to scale and with sufficient detail and clarity to demonstrate that the work complies with the requirements of Sections 302, 307, 309, 401, and 601, IMC 2012 (e.g. balancing information, specifications for mechanical equipment, duct layout, etc.). Reference: Section 107.2.1, IBC 2012.]
2. The heating and cooling load calculations (for the city of "Tuscon"), based on incorrect exterior design conditions, do not include a summary of the total loads for each of the three systems. [Initial comment: Provide heating and cooling load calculations, using the exterior design conditions shown in Section 302.2, IECC 2012, as modified by the City of Tucson.]
3. Revise the COMcheck mechanical compliance certificate using the actual heating and cooling capacities for the HVAC systems. (Hint: your heating and cooling capacities are off by a factor of 1,000.) [Initial comment: Show that the proposed HVAC systems and their controls comply with all of the applicable sections of the 2012 International Energy Conservation Code. Reference: Sections C403.2, C403.3, and C403.4, IECC 2012.]
4. Condensate piping not found - add labels for identification. [Initial comment: Show the size, routing, and termination of the condensate drains. Reference: Section 307.2.1, IMC 2012 as amended by the City of Tucson.]
5. Provide a summary of the total outside airflow rate required for each ERV. See Section 403.3.2.3, IMC 2012 for the calculations required for multiple zone recirculating systems. [Initial comment: Provide ventilation calculations based on section 403.3, IMC 2012. Reference: Section 403.2, IMC 2012.]
6. The 10% limit refers to the leakage within an ERV when it is used to recover energy from an exhaust air stream. [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 2012.]
10/16/2018 ROBERT SHERRY PLUMBING-COMMERCIAL REVIEW Reqs Change 1. Provide a detail of the water heater installations for the training house, including the excess pressure reliefs, expansion tanks, safety pans, and valves. Reference: Sections 503, 606.1, and 607.3 , IPC 2012.
2. Show how the vent for the gas-fired water heater in the training house will be handled. Reference: Section 107.2.1, IBC 2012.
3. Provide waste and vent isometrics for the training house. Reference: Section 107.2.1, IBC 2012.
4. An approved 2-way cleanout fitting is allowed to be used at the junction of a building drain and a building sewer; otherwise, cleanouts shall open to allow cleaning in the direction of flow. Reference: Sections 708.3.5 and 708.5, IPC 2012. [Initial comment: Provide sheet TH-P as noted on sheet P-3. Reference: Section 107.2.1, IBC 2012.]
5. Clarify how the vents labeled as "VTR" for the training house are to terminate. Reference: Section 904.3, IPC 2012.
6. Identify the plumbing fixtures and water heaters on the plumbing plans. [Initial comment: Identify the plumbing fixtures and show the water piping, water heaters, and on the plumbing plans. Coordinate the plumbing isometrics with the plumbing plans (e.g. where are the two P-11 fixtures located). Provide a unique number for each specified fixture. Reference: Section 107.2.1, IBC 2012.]
7. A trough urinal is still included in the fixture specifications. [Initial comment: The use of trough urinals is prohibited. Reference: Section 401.2, IPC 2012.]
8. Comment not addressed. [Initial comment: Show the route and termination of the safety pan drains from the water heaters WH-2 and WH-3. Reference: Section 504, IPC 2012.]
9. Use the low value of the water pressure range for pipe size calculations. [Initial comment: Verify the minimum available water pressure for this address with Tucson Water; the data from Tucson Water appears to show a pressure range of 41 to 47 PSI. Revise the water pressure calculations as required.]
10. The recirculation piping has been removed from the water heater detail but the hot water pipe from the water heater located in room 103 has a developed length to the lavatory in room 125 that is in excess of 50-feet. Show how the requirements of Section 607.2, IPC 2012 are to be met. [Initial comment: Revise the water heater detail to show the hot water return for the recirculating hot water system connecting to the cold-water inlet of the water heater. Reference: Section 607.2.2, IPC 2012.]
11. The plumbing plan for the second floor notes a 4" waste stack dropping down to the first floor from room 206 but on sheets P-2 it is a 4" pipe and on P-3 it is a 3" stack. Clarify the size of the stack.
12. The 4" stack in room 109 appears to be dropping down in a water closet partition. Is this the intension? [Initial comment: Horizontal branches shall connect no closer than ten diameters downstream of the bases of vertical stacks (e.g. 40" for a 4" stack). Reference: Section 704.3, IPC 2012.]
13. Coordinate the riser diagram with the first floor plumbing plan; it does not appear that the cleanout is located on the stack. [Initial comment: Provide a cleanout at the base of each waste stack. Reference: Section 708.3.4, IPC 2012.]
14. Provide cleanouts sized for the nominal size of pipes that they serve up to 4-inches. Reference: Section 708.7, IPC 2012.
