CONTRACTOR TO FIELD VERIFY EXISTING DUCTWORK LOCATION, SIZE, AND ELEVATION PRIOR TO REMOVAL. COORDINATE ANTICIPATED ROUTING WITH EXISTING AND NEW DUCTWORK, PIPING, AND CONDUITS. CONTACT ENGINEER IF FIELD CONDITIONS REQUIRE ALTERNATIVE ROUTING. VERIFY THAT ALL SERVICES TO BE REMOVED DO NOT SERVE AREAS OUTSIDE INDICATED SCOPE OF WORK. B. PIPE AND DUCT ROUTINGS AND CLEARANCES INDICATED ARE BASED ON BEST AVAILABLE INFORMATION. CONTRACTOR SHALL VERIFY PIPING, DUCTWORK, ELECTRICAL, AND STRUCTURAL DETAILS OF EXISTING AND NEW INSTALLATIONS DURING AND AFTER DEMOLITION (PRIOR TO NEW INSTALLATIONS) TO DETERMINE WORK NECESSARY TO INSTALL WORK AS SHOWN AND INTENDED. CONTRACTOR SHALL CONTACT THE ENGINEER WITH ANY CONCERNS UPON COMPLETION OF THIS EFFORT. C. COORDINATE OUTAGES WITH OTHER CONTRACTORS, OWNER, AND MAINTENANCE STAFF. PROVIDE SUFFICIENT ADVANCE SCHEDULING TO MEET OCCUPANTS AND FACILITY PERSONNELS REQUIREMENTS FOR PLANNING AND COORDINATING FOR SYSTEMS WHICH MAY NOT BE EASILY INTERRUPTED. D. WHERE MECHANICAL, ELECTRICAL, PLUMBING, AND FIRE PROTECTION WORK IS DETERMINED TO PENETRATE EXISTING FLOORS, WALLS, CEILING, OR ROOF, THE OPENING THROUGH WHICH THE ABOVE DESCRIBED ITEM IS TO PASS MUST BE REPAIRED OR BUILT BACK BY THE CONSTRUCTION TRADE SKILLED IN THE WORK TO BE PERFORMED. SUBCONTRACTOR SHALL BE RESPONSIBLE FOR PROCURRING THE SERVICES OF SKILLED CONTRACTOR. E. PROVIDE TEMPORARY PATCHING AS REQUIRED FOR INFECTION CONTROL AS DETERMINED BY HOSPITAL INFECTION CONTROL DEPARTMENT AND MAINTAIN EXISTING FIRE AND SMOKE RATINGS. F. WHERE PRE-DEMOLITION AIRFLOW READINGS ARE NOTED, TAKE READINGS PRIOR TO BEGINNING ANY DEMOLITION WORK OR CONSTRUCTING NEGATIVE AIR PRESSURE BARRIERS. PRE- DEMOLITION TAB WORK WILL LIKELY OCCUR AFTER NORMAL HOURS, CONFIRM WITH OWNER. G. ALL DUCTWORK, PIPING, AND EQUIPMENT INDICATED BY DASHED LINETYPE SHALL BE REMOVED AS DESCRIBED BY PLAN NOTES. REMOVE OR REUSE ASSOCIATED HANGERS. DO NOT LEAVE UNUSED EQUIPMENT ABANDONED ABOVE CEILING. ALL TERMINAL UNITS TO BE REMOVED SHALL ALSO HAVE SUPPLY DUCTS REMOVED BACK TO MAIN DUCTS AS INDICATED AND CAP SUITABLE FOR +4" W.G. REMOVE PIPING RUNOUTS BACK TO MAIN AND CAP. FOR PIPING RUNOUTS THAT ARE TO BE REUSED, REMOVE ALL CONTROL VALVES, BALANCE VALVES, STRAINERS , AND PIPING ACCESSORIES TO BRANCH SHUT-OFF VALVES. ALL EXISTING TERMINAL UNITS, DDC CONTROLLERS, ROOM PRESSURE MONITORS, AND HARDWARE TO BE REMOVED SHALL BE DONE SO IN A MANNER TO MINIMIZE DAMAGE AND OFFERED TO THE OWNER. CONTRACTOR SHALL DISCARD ALL DEVICES NOT WISHED TO BE RETAINED BY THE OWNER. GENERAL MECHANICAL NOTES A. CONTRACTOR TO INSTALL ACCESS PANELS AT ALL FIRE DAMPERS. REFER TO DETAILS AND SPECIFICATIONS FOR MINIMUM ACCESS PANEL SIZES. COORDINATE LOCATIONS TO ENSURE ACCESS PANELS ARE NOT OBSTRUCTED. B. REFER TO SCHEDULES FOR DIFFUSER AND TERMINAL UNIT RUNOUT SIZES. C. UNLESS NOTED OTHERWISE, TERMINAL UNIT DISCHARGE DUCT SHALL BE THE SAME SIZE AS THE TERMINAL UNIT DISCHARGE CONNECTION. D. LOCATE ALL TERMINAL UNITS, DAMPERS, VALVES, AND EQUIPMENT REQUIRING ACCESS IN AN UNOBSTRUCTED LOCATION ABOVE LAY-IN CEILING. COORDINATE THE INSTALLATION OF A CEILING ACCESS PANEL WITH GENERAL CONTRACTOR. E. FIELD VERIFY LOCATION OF ALL FLOOR PENETRATIONS PRIOR TO CUTTING TO ASSURE THAT NO FLOOR PENETRATION CONFLICTS WITH EXISTING BEAMS OR JOISTS. FLOOR PENETRATIONS SHALL BE ONLY THROUGH THE SLAB. DO NOT CUT THROUG BEAMS OR JOISTS. NOTIFY ARCHITECT AND ENGINEER FOR ANY REQUIRED MODIFICATIONS PRIOR TO CUTTING. F. REFER TO TERMINAL UNIT SCHEDULE FOR PIPE RUNOUT SIZES. G. MINIMUM PIPE SIZE SHALL NOT BE LESS THAN 3/4". H. ALL NEW AIR-HANDLING SYSTEMS AND ASSOCIATED DISTRIBUTION SHALL COMPLY WITH NFPA-90A. I. ALL DUCTWORK AND PIPE INSULATION SHALL BE INSTALLED CONTINUOUSLY THROUGH WALLS. OPENINGS SHALL BE FRAMED LARGE ENOUGH TO ACCOMMODATE INSULATED PIPE/DUCT. ALLOW ENOUGH ANNULAR SPACE FOR PROPER SEALANT. NON-RATED WALLS SHALL HAVE NON- COMBUSTIBLE SEALANT. RATED BARRIERS SHALL HAVE A UL-LISTED FIRESTOPPING ASSEMBLY. INSTALL FIRESTOPPING ASSEMBLY IN COMPLIANCE WITH MANUFACTURER'S WRITTEN INSTALLATION INSTRUCTIONS AND IN COMPLIANCE WITH UL-LISTED ASSEMBLY. J. COORDINATE THERMOSTATS, HUMIDISTATS, DIFFERENTIAL PRESSURE SENSORS, AND ALL OTHER WALL MOUNTED DEVICES WITH ALL DISCIPLINES PRIOR TO ROUGHING IN. K. REFER TO H801 DRAWING FOR DETAILS. WHERE APPROPRIATE, SPECIFIC DETAILS HAVE BEEN REFERENCED ON THE PLANS. IN ORDER TO MAINTAIN DRAWING CLARITY, NOT ALL DETAILS HAVE BEEN CALLED OUT BUT DO PERTAIN TO THE SCOPE OF THIS PROJECT. L. CONTRACTOR SHALL DRAIN SYSTEM PIPING AS NECESSARY. BUILDING WILL REMAIN IN OPERATION DURING CONSTRUCTION. M. PROTECT ALL SUPPLY, RETURN, AND EXHAUST AIR OPENINGS THROUGHOUT CONSTRUCTION FROM DAMAGE, DIRT, AND DEBRIS. N. CLEAN ALL SUPPLY DIFFUSERS, RETURN AIR GRILLES THAT ARE EXISTING TO REMAIN PRIOR TO PROJECT COMPLETION TO REMOVE ANY DIRT OR DEBRIS. www.studio3design.net Phone: (317) 595.1000 8604 Allisonville Road, Suite 330 Indianapolis, IN 46250 A B C D E 1 2 3 4 5 6 7 A B C D E THESE DRAWINGS ARE THE PROPERTY OF STUDIO 3 DESIGN, INC.
