AutoCAD SHX Text PIPING SHALL BE FIELD ROUTED IN ACCORDANCE WITH APPROPRIATE ENGINEERING PRACTICES, INDUSTRY STANDARDS, AND GOVERNING CODES/REGULATIONS. ROUTE OF PIPE, INCLUDING CLEARANCE, IS THE RESPONSIBILITY OF THE CONTRACTOR. UNIONS, BUSHINGS, AND REDUCING INSERTS, NOT SHOWN ON THE DRAWINGS, BUT REQUIRED FOR INSTALLATION SHALL BE PROVIDED. INDICATED EXISTING CONDITIONS (E.G. SIZE/LOCATION OF PIPING, DUCTWORK, EQUIPMENT, AND BUILDING ELEMENTS) ARE BASED ON INFORMATION OBTAINED FROM AVAILABLE RECORD DRAWINGS AND/OR FIELD SURVEYS. EXISTING CONDITIONS NOT RELATED TO THE WORK MAY NOT BE SHOWN. EXISTING CONDITIONS ARE PROVIDED FOR THE CONVENIENCE OF THE CONTRACTOR ONLY AND ARE NOT GUARANTEED TO BE COMPLETE OR CORRECT. PLANNING AND CHECKING HAS BEEN DONE BY THE ENGINEER TO MINIMIZE INTERFERENCES. PRIOR TO START OF CONSTRUCTION, CONTRACTOR SHALL FIELD VERIFY LOCATION AND SIZES OF ELEMENTS RELATED TO THE WORK. ROUTING OF PIPING AND DUCTWORK SHOWN ON DRAWINGS IS DIAGRAMMATIC. CONTRACTOR SHALL ASCERTAIN THAT INTERFERENCES WILL NOT BE ENCOUNTERED, PREVENTING THE DISASSEMBLY OF PARTIALLY OR COMPLETELY ERECTED SYSTEMS FOR RE-ROUTING TO CLEAR OBSTRUCTIONS WHICH MAY EXIST. EXISTING VALVES SHALL NOT BE ASSUMED TO PROVIDE POSITIVE SHUT-OFF. COORDINATE REQUIRED OPERATION OF VALVES WITH GOVERNMENT PERSONNEL. VALVES REQUIRED FOR SYSTEM ISOLATION SHALL BE TESTED PRIOR TO THE WORK SUCH THAT PROPER PLANNING AND WORK SEQUENCING CAN BE PERFORMED. COORDINATE VALVE TESTING WITH CONTRACTING OFFICER. IMMEDIATELY NOTIFY CONTRACTING OFFICER'S TECHNICAL REPRESENTATIVE OF VALVES THAT FAIL TO PROVIDE POSITIVE SHUT-OFF. CONTRACTOR SHALL PROVIDE LOW POINT HOSE END PIPE DRAINS WITH CAPS AS REQUIRED TO COMPLETELY DRAIN SYSTEMS INSTALLED UNDER THIS WORK. PROVIDE MANUAL AIR VENTS WITH CAPS AT HIGH POINTS IN SYSTEMS INSTALLED UNDER THIS WORK. PROVIDE AN EMERGENCY SHUTOFF SWITCH IN THE HVAC CONTROL SYSTEM TO IMMEDIATELY SHUT DOWN THE AIR DISTRIBUTION AND EXHAUST SYSTEMS IN THE BUILDING AND CLOSE ALL DAMPERS LEADING TO THE OUTSIDE.

GENERAL MECHANICAL NOTES

AutoCAD SHX Text REMOVE HANGERS, SUPPORTS, ANCHORS AND GUIDES, MISCELLANEOUS STRUCTURAL STEEL, CONTROLS AND INSTRUMENTATION, CONTROL WIRES AND TUBING, SPECIALTIES, VENTS AND DRAINS, ELECTRICAL POWER, AND OTHER ASSOCIATED ACCESSORIES IN THE PROCESS OF PIPE, DUCTWORK, AND EQUIPMENT DEMOLITION. SUPPORTS FOR PIPE, DUCTWORK AND SYSTEMS SHOWN OR NOTED TO BE DEMOLISHED THAT PENETRATE THROUGH THE INTERIOR ROOF INSULATION SHALL BE CUT 3" ABOVE INSULATION AND COVERED WITH A PROTECTIVE PLASTIC CAP (BRIGHT ORANGE). EXISTING PIPING, DUCTWORK AND SYSTEMS SHOWN OR NOTED TO BE DEMOLISHED SHALL BE DISCONNECTED AND REMOVED BACK TO SERVICE MAINS, UNLESS OTHERWISE INDICATED. EXISTING PIPING, DUCTWORK AND SYSTEMS SHOWN TO REMAIN IN PLACE SHALL BE CAPPED, PLUGGED, BLIND FLANGED OR OTHERWISE SEALED. NO PIPING OR DUCTWORK SHALL BE LEFT OPEN ENDED UNLESS OTHERWISE INDICATED. BEFORE DISCONNECTING PIPING, VERIFY THAT PIPING HAS BEEN ISOLATED, VENTED, AND DRAINED. REMOVE ALL FLUIDS AND GASES CONTAINED WITHIN PIPING, TANKS, AND EQUIPMENT SHOWN OR NOTED TO BE DEMOLISHED. NO FLUIDS SHALL BE ALLOWED TO DRAIN TO THE BUILDING SANITARY OR STORM SYSTEM WITHOUT WRITTEN APPROVAL FROM THE CONTRACTING OFFICER. THE CONTRACTOR SHALL BE RESPONSIBLE TO CONTAIN, HAUL, AND LEGALLY DISPOSE OF REMOVED FLUIDS AND GASES OFFSITE. DEMOLITION SHOWN IS BASED ON AS-BUILT DRAWINGS AND FIELD INVESTIGATION TO THE EXTENT POSSIBLE. FIELD VERIFY EXACT ROUTING OF PIPING AND DUCTWORK PRIOR TO COMMENCEMENT OF WORK. PATCH AND SEAL WALL AND FLOOR OPENINGS WHERE PIPING AND DUCTWORK IS REMOVED PER ARCHITECTURAL DETAILS. PROVIDE TEMPORARY CAPS FOR OPEN ENDS OF PIPING AND DUCTWORK TO REMAIN UNTIL NEW CONNECTIONS ARE MADE.
