| 04/10/2003 | STANTEC | 3RD PARTY REVIEW-COMMERCIAL | REVIEW | Denied | City of Tucson No. T03CM00204 GENERAL: q There are no general comments to be addressed. ARCHITECTURAL: q There are no architectural comments to be addressed. STRUCTURAL: q There are no structural comments to be addressed. MECHANICAL: q There are no mechanical comments to be addressed. PLUMBING: q There are no plumbing comments to be addressed. ELECTRICAL: q Address bonding of the electrical service to the metal water and gas piping [1999 NEC Art. 250-104(b)]. This previous comment has not been fully addressed. Please clarify grounding of the electrical service. Riser diagram on sheet 16.7 indicates grounding at the CT can and refers to a Grounding detail on the same sheet. The Grounding detail does not show the CT can or Main Disconnect switch. It appears that Main Bonding jumper is installed in panel DP. q All roof receptacles shown on sheet 16.4 shall be GFCI type [1999 NEC Art. 210-8(b)]. This previous comment has not been addressed. q A near duplicate of Panel "A" has replaced panel "C" on Sheet 16.3. This near duplicate panel is even labeled as Panel "A" so there are now two panels labeled "A" and no panel labeled "C". Please coordinate. q HVAC Motor & Equipment schedule on sheet 16.4 does not match with loads and branch circuits shown on panel schedules. For example, RT-1 is shown on HVAC Motor & Equipment Schedule could have load up to 112 Amp. However, schedule for panel "C" shows only 60 Amp branch circuit for RT-1. Please check and correct for all loads. This previous comment could not be checked for correction because of the preceding comment regarding missing Panel "C". q Equipment Connections schedule on sheet 16.4 does not match loads and branch circuit shown on panel schedules. For example, item #20B Bun Freezer requires 208V, 3 phase branch circuit with #12 wires. However, schedule for panel shows the Bun Freezer connected to 30 Amp, single pole circuit breaker. Please check and correct for all loads. This previous comment has been partially addressed, however a portion could not be checked for correction because of the preceding comment regarding missing Panel "C". q Schedule for panel "DP" on Sheet 16.7 shows 200 Amp feeders to the panels "C" and "cook center" to include #6 equipment grounding conductor. However, the one line diagram on the same sheet shows these feeders with a #2 equipment grounding conductor. Please clarify. This previous comment has been partially addressed. However, now the schedule for panel "DP" on sheet 16.3 shows 2" conduits for 200 Amp feeders to the branch circuit panels while the riser diagram on sheet 16.7 shows the same feeders in 2.5" conduits. Please clarify. q Branch circuit loads are showing in kW on panel schedules. Simple addition of the loads on panel "C" gives the same load in kW as shown for total connected load for the panel in kVA. It is not reasonable to assume 100% power factor for loads that include lighting and small motors. Please recalculate the connected load for all panels with a consideration to the power factor. This previous comment could not be checked for correction because of the preceding comment regarding missing Panel "C". q Please add to all load calculations 25% of all continuous loads [1999 NEC Art. 215.3] and 25% for largest motor [1999 NEC Art. 220-4(a)] as required for sizing overcurrent protection devices. This previous comment has not been addressed. q After replacing loads shown on schedule for panel "C" on sheet 16.7 for RT-1, RT-2 and MUA-1 with maximum loads shown in HVAC Motor & Equipment schedule on sheet 16.4 for the units, calculated connected load on the panel exceeds panel and feeder capacity. This previous comment could not be checked for correction because of the preceding comment regarding missing Panel "C". q Electrical Load Summation on sheet 16.7 shows service load of 517 Amps. After considering power factor, additional 25% of continuous load and largest motor load, errors in determining branch circuits loads, the calculated connected service load could exceed the service capacity. Please correct the load calculations and revise service size if required. This previous comment could not be checked for correction because of the preceding comment regarding missing Panel "C". q Fault current calculations are not provided in the electrical plans. Rating of the equipment is covered by a general note directing the contractor to coordinate with utility and provide equipment that is series rated with upstream devices. There is also a General Note #7 on Sheet 16.7 that shows distribution system rated at 65,000 AIC. Please provide fault calculations and describe your method of limiting the available fault current to the equipment rating. This previous comment has not been fully addressed. We received the letter from the engineer of record. The question is how does this design go from a service with an AIC of 55,600 to three panels located less than 2 feet away, each with and AIC or 22,000? Please provide documentation. -End of Review- |
