4) P-1 Hangar floor drainage is required to be processed through an oil/water separator. (IBC 412.4.3) 9-14-12 UNRESOLVED. OIL/WATER SEPARATOR IS STILL MISSING FROM PLANS AND PROPOSED SYSTEM DOES NOT MEET CODE REQUIREMENTS. 9-25-12 UNRESOLVED. 11-02-12 UNRESOLVED. THE SYSTEM IS REQUIRED TO DRAIN BY GRAVITY PER UPC 709. INTRODUCTION OF A SUMP PUMP INTRODUCES THE LIKELYHOOD OF A SYSTEM FAILURE. RESOLVED PER RESUBMITTAL OF 11-13-12.
5) P-1 “The drainage piping of each building …… shall be vented by means of one or more vent pipes, the aggregate cross-sectional area of which shall be not less than that of the largest required building sewer, as determined from Table 7-5.” (UPC 904.1) The required drainage service for this building is only 3". The 3" VTR is only considered to have the venting capacity of the 2" connecting riser below. If that were increased to 3" the 2" and 1-1/2" connecting branches would still only provide about 70% of the required venting capacity. 9-14-12 UNRESOLVED. ISOMETRIC WAS UNCHANGED. RESOLVED PER RESUBMITTAL RECEIVED 9-25-12.
6) P-1 The gas piping schematic does not represent the layout as shown on the floor plan. 9-14-12 UNRESOLVED. RTH-2 IS NOT CONNECTED WHERE SHOWN ON PLANS, TWO GF-1 ON ISO AND ONLY ONE ON PLANS, THE BOILER AND WATER HEATER ARE MISSING FROM THE ISOMETRIC, LOCATION OF FUTURE LOAD IS NOT INDICATED, ETC.

G) HB-1 & WH-1 in the hangar require backflow protection. 9-14-12 UNRESOLVED. INTERIOR HOSE BIBS IN OTHER THAN RESIDENTIAL APPLICATIONS ARE CONSIDERED BY THE AWWA CROSS CONNECTION CONTROL MANUAL TO BE A HIGH HAZARD AND WOULD NORMALLY REQUIRE AN RP DEVICE; HOWEVER THE MOA HAS BEEN ALLOWING EITHER A PVB OR AN SVB FOR THIS APPLICATION. RESOLVED PER RESUBMITTAL RECEIVED 9-25-12.
H) Gas appliances do not account for 805 MBH connected load. 9-14-12 UNRESOLVED. THE CURRENT GAS ISOMETRIC PLUS THE WATER HEATER, BOILER AND FUTURE LOAD OF 325 MBH TOTAL ONLY 1470 MBH DO NOT EQUAL THE 1875 MBH SHOWN ON THE 2" MAIN COMING OFF OF THE GAS METER.
