| 01/10/2006 | LINDA BUCZYNSKI | ELECTRICAL-COMMERCIAL | REVIEW | Denied | TRANSMIT ORIGINAL DRAWINGS WITH NEXT SUBMITTAL. PLEASE CALL AT 791-5550 X1106 OR EMAIL AT Linda.Buczynski@tucsonaz.gov IF YOU CARE TO DISCUSS. 1. Add the lighting fixture to Ckt L2-31 on the panel schedule. 2. Please provide breakout of Non-Coincident loads for the feeder calculations for Panel P1 Section 2. When the Plans Examiner subtracts the Electric Heat the result is still over the panel capacity. Also demonstrate that no phase is being overloaded. 3. For Panel C1 specify exactly which loads are considered non-coincident. Demand factors receptacle loads, per NEC 220.13, may only be taken for outlets computed at not more than 180 VA; it appears that only Ckts 1,3,6, & 10 fit this category, although 6 and 10 are undercounted. 4. Connected loads for the elevators on the Electrical Load Summary do not correspond to those on Panel SWBD. Also note any changes in the comments above to carry forward into the service load calculations. 5. On the Electrical Riser Diagram, the #8 GND needs to be increased to #6, for Elevators 1 & 2. Reference NEC Table 250.122. 6. "Conduit and conductor specifications on Electrical Load Summary are not consistent with those on the Electrical Riser Diagram, and a third instruction is specified on the First Floor Electrical Power Plan." THIS COMMENT WAS MADE ON THE TWO PREVIOUS SUBMITTALS. On Electrical Load Calculations Elevator #2 feeder size is #3, but on the Electrical Riser Diagram it is 1/0; on Panel SWBD and First Floor Electrical Power Plan both Elevators are fed by 1/0. Meter Center #1 & #2 loads on Panel SWBD differ from those of the Multi-Family Dwelling Load Calculations and the Apartment Building Electrical Load Summary. 7. For the purpose of the Meter Bank Feeder calculations, the appropriate load to satisfy Article 220 should include the fan for the AHU on Ckt 10,12. The heaters are 3 KW themselves, but the fan runs with the heater. 8. Fault calculations are based on 6 sets of 500 MCM conductor. Electrical Riser Diagram shows 7 conduits between the TEP transformer and the service entrance, one of which is a spare, and the remainder 500 MCM. First floor power plans shows only 5 sets. Please clarify. 9. Panel SWBD is rated for 2000A on its Panel Schedule, and 2500A on the Electrical Riser Diagram. Electrical Load Summary Totals greater than 2000A. Clarify. 10. Panel SWBD panel schedule is set up with 12 switches, which does not comply with the requirements of NEC 230.71 Maximum Number of Disconnects. From the set up on the Electrical Riser Diagram, it appears that Mains 1-4 would serve as 4 (maximum 6) disconnect switches, which looks right, with the second and third vertical rows (from the left) being served from Main #4. Now, the Elevation of Main Distribution Panel shows SWBD as having a 2000A main switch. Clarify. 11. Indicate all fault current ratings at the Meter Centers. Please note that for Meter Center 1 the AFC appears to be 23705 on the basis of 100'; however, by scaling from the drawing the distance appears to be 175, thus AFC appears to be 16416; please clarify, as calculated value in this submittal is 20000A. Please note that for Meter Center 2 the AFC appears to be 35120, not 31000; please clarify. Please note that for Meter Center 3 the AFC appears to be 35119 on the basis of 50' and 2 sets of 250 KCM; however, by scaling from the drawing the distance appears to be 100', and the conductor used is 4/0; please clarify. 12. Please provide for the Equipment Grounding Conductor in the feeders to the Meter Centers. 13. On Sheet E-7, the grounding of the telephone system, has the connection to a 5/8" X 8' ground rod (to building GND per NEC 800.40 (B). Since Note 3 on the Electrical Riser Diagram Sheet E-9 specifies a 10' ground rod, it needs to be clarified the size, 8' or 10'. This was noted previously. |

| 01/10/2006 | ROBERT SHERRY | PLUMBING-COMMERCIAL | REVIEW | Denied | 1. The water piping design may be based on the data from the Tucson Fire Department (65 PSI) instead of the data from Tucson Water (47 to 54 PSI before the meter and reduced pressure backflow preventer). But the water demand is to be calculated based on the fixture units shown in Tables 6-3 or A-2 of the 1994 UPC. 2. The cut sheet for the Wilkins Model 575 reduced pressure backflow preventer does not indicate that it is ASSE listed (Standard 1013) or approved by the Foundation for Cross Connection Control and Hydraulic Research at the University of Southern California, both of which are required by Tucson Water. 3. Coordinate sheet SU-1 and the City of Tucson Water Distribution System drawing in the project drawing set. Reference Sections 103.3.3, 610.3, and Appendix A, UPC 1994. 4. Clarify how the condensate from the independent air conditioning systems for the elevator machine rooms is being collected. Provide a riser diagram for the indirect waste receptor in room 129. Show how the condensate from the air conditioner for room 135 is being collected. Reference Sections 804.1 and 807.1, UPC 1994. |
| 01/10/2006 | ROBERT SHERRY | MECHANICAL-COMMERCIAL | REVIEW | Denied | 1. The 12/14/05 response to this comment is acceptable but the entry for AH-1 in the Air Unit Schedule on sheet M-5 does not appear to have been changed. [Section 403.3.2 allows "the RATIO of outdoor air to total supply air for the system to be determined based on the space having the largest outdoor air requirement…". For example, if the beauty shop served by AHU-1 requires 36% outside air then AHU-1 can be set to deliver 36% outside air to all of the spaces it serves. Reference Sections 403.3 and 403.3.2, IMC 2000.] 2. The 12/14/05 response to this comment is acceptable if the arithmetic is corrected (0.25/(1+0.25-0.30) = 0.26, not 0.24) and the outdoor air quantity adjusted appropriately. [The Community room appears to be an assembly room, not a lobby. Adjust the ventilation requirements accordingly. Note that the mechanical plan shows AHU-3 delivering only 1820 CFM, not 2000 CFM. Reference Section 403.3, IMC 2000.] 3. The 12/14/05 response to this comment is acceptable if the arithmetic is corrected (according to the drawing, AH1B is supplying a total of 1070 CFM and Z = outdoor air required for the seating area / supply air to the seating area) and the outdoor air quantity adjusted appropriately. [The Seating rooms (approximately 470 square feet) appear to be a lobby with a corridor (120 square feet) running through it. The reception room appears to function as an office. Adjust the ventilation requirements accordingly. Note that the mechanical plan shows AHU-1B delivering only 1040 CFM, not 1020 CFM. Reference Section 403.3, IMC 2000.] |
