GENERAL NOTES

A. WORK SHALL CONFORM TO OWNERS CONSTRUCTION AND INFLECTION CONTROL

PROCEDURES.

B. WHERE DEMOLITION WORK NECESSARILY DIMINISHES OR ADVERSELY AFFECTS

LIFE-SAFETY SYSTEM SUCH AS SPRINKLER SYSTEMS AND/OR FIRE ALARM SYSTEMS

COORDINATE SUCH WORK THROUGH CONSTRUCTION MANAGER, OWNER AND FIRE

MARSHAL.

C. SERVICES SHALL NOT BE INTERRUPTED OR CHANGED WITHOUT WRITTEN

PERMISSION AND SCHEDULE APPROVED BY OWNER. WHERE DEMOLITION WORK

INTERFERES WITH OWNERS USE OF PREMISES, SCHEDULE WORK THROUGH OWNER

TO MINIMIZE INCONVENIENCE TO OWNER.

D. CONSTRUCTION MANAGER AND CONTRACTOR SHALL COORDINATE AND FIELD

VERIFY EXISTING PIPING, DUCTWORK, AND CONTROL DISCONNECTION POINTS.

PROVIDE VALVES, TEMPORARY CAPS AND/OR PLUGS TO ISOLATE PORTIONS OF

SYSTEMS TO FACILITATE PHASING OR WORK OR TO ISOLATE PORTIONS OF

SYSTEMS TO REMAIN FROM PORTIONS TO BE DEMOLISHED.

E. EXISTING DUCTWORK, PIPING AND EQUIPMENT LOCATIONS SHOWN ARE BASED ON

AVAILABLE DOCUMENTATION OF EXISTING CONDITIONS AND FIELD OBSERVATIONS.

DRAWINGS DO NOT SHOW IN DETAIL FULL EXTENT OF REQUIRED DEMOLITION WORK.

CONTRACTOR SHALL VISIT SITE AND REVIEW PRIOR TO BID OR NEGOTIATED

CONTRACT TO DETERMINE SCOPE O DEMOLITION WORK. PROVIDE COMPLETE

DEMOLITION WORK REQUIRED TO ACCOMPLISH PROJECT SCOPE. COORDINATE

EXTENT OF DEMOLITION WORK WITH DRAWING INDICATING NEW WORK.

F. WHERE EQUIPMENT, PIPING, DUCTWORK AND OR OTHER ITEMS ARE INDICATED TO

BE REMOVED, REMOVE RELATED SUPPORTS BACK TO ATTACHMENTS TO BUILDING

STRUCTURE. IN PERFORMING DEMOLITION WORK, DO NOT DAMAGE OR MODIFY

BUILDING STRUCTURE, INCLUDING REMOVAL OF CONCRETE OR STEEL STRUCTURAL

MATERIALS OR COMPONENTS TO ACCOMPLISH REMOVAL OF ATTACHMENTS TO

BUILDING STRUCTURE WITHOUT WRITTEN APPROVAL OF STRUCTURAL ENGINEER OF

RECORD.

G. OTHER THAN STRUCTURAL ATTACHMENTS, WHERE EXISTING WORK IS REMOVED,

MATERIALS SHALL BE REMOVED TO A POINT BELOW FINISHED FLOORS OR BEHIND

FINISHED WALLS TO ALLOW FOR THE INSTALLATION OF NEW FINISHED MATERIALS.

SUPPORT REMAINING WORK IN ACCORDANCE WITH REQUIREMENTS FOR NEW

INSTALLATION.

H. WHERE CONTROL DEVICES ARE REMOVED, REMOVE ASSOCIATED WIRING, CONDUIT,

AND PNEUMATIC TUBING AS APPLICABLE.

I. PATCH OPENINGS IN WALLS, CEILINGS, ROOF AND FLOOR SURFACES DAMAGED,

CREATED, OR LEFT BY DEMOLITION WORK. PATCHING SHALL MATCH EXISTING FIRE-

RESISTANCE RATINGS AND WHERE POSSIBLE,SHALL MATCH EXISTING ADJACENT

SURFACES AS TO THICKNESS, TEXTURE, MATERIALS AND COLORS TO SATISFACTION

OF OWNER.

J. EXISTING TO REMAIN INSULATION DAMAGED BY CONTRACTOR SHALL BE REPAIRED

OR REPLACED IN KIND.

K. PROTECT EXISTING DUCTWORK, DIFFUSERS, AND GRILLES TO REMAIN FROM

CONSTRUCTION DUST AND DEBRIS.

CONNECTION ON THE FACE OF THE CHILLER CH-1 AND THE FLANGE CONNECTION TO

THE EXISTING CONTROL-VALVE MOUNTED OVERHEAD AND REMOVE THE EXISTING

PIPING BETWEEN THE TWO POINTS AND THE CONTROL VALVE TO ALLOW FOR

REMOVAL AND NEW CHILLER TO BE INSTALLED.

9. DISCONNECT EXISTING CONDENSER WATER RETURN PIPING FROM THE FLANGE

CONNECTION ON THE FACE OF THE CHILLER CH-1 AND THE FLANGE CONNECTION IN

THE OVERHEAD LINE AND REMOVE THE EXISTING PIPING BETWEEN THE TWO POINTS

TO ALLOW FOR REMOVAL OF THE CHILLER

10. DISCONNECT EXISTING CHILLED WATER RETURN PIPING FROM THE FLANGE

CONNECTION ON THE FACE OF THE CHILLER CH-1 AND THE FLANGE CONNECTION

OVERHEAD AND REMOVE THE EXISTING PIPING BETWEEN THE TWO POINTS TO ALLOW

FOR REMOVAL OF THE CHILLER.

11. DISCONNECT EXISTING CHILLED WATER SUPPLY PIPING FROM THE FLANGE

CONNECTION ON THE FACE OF THE CHILLER CH-1 AND THE FLANGE CONNECTION FOR

THE EXISTING ISOLATION VALVE AND REMOVE THE EXISTING PIPING AND FAILED

BALANCE VALVE BETWEEN THE TWO POINTS TO ALLOW FOR REMOVAL OF THE

CHILLER.

12. EXISTING REFRIGERANT RELIEF PIPING TO BE REMOVED TO ALLOW EXISTING

CHILLER PLACEMENT PLAN - NORTH PLANT (FOR REFERENCE)

THE CHILLER REPLACEMENT PROJECT FOR THE NORTH CENTRAL PLANT WILL INCLUDE THE REPLACEMENT OF EXISTING CHILLERS CH-1 AND CH-2 LOCATED IN THE FRONT SECTION OF THE NORTH

PLANT. EXISTING CHILLER CH-3, LOCATED IN THE REAR EQUIPMENT ROOM OF THE NORTH PLANT WILL REMAIN IN PLACE AND IN SERVICE. THE REPLACEMENT PROJECT WILL INCLUDE THE REPLACEMENT OF EXISTING CHILLERS CH-1 AND CH-2, ALONG WITH THE REPLACEMENT OF SELECTED BALANCE AND ISOLATION VALVES. SELECTED CONTROL DEVICES AS WELL AS MAGNETIC FLOW

METERS WILL ALSO BE INCLUDED IN THE REPLACEMENT

THE NEW CHILLERS WILL INCLUDE A MARINE WATER BOX ON THE CONDENSER BARREL FOR EACH CHILLER. SINCE NEW CHILLER CH-1 WILL HAVE THE CONDENSER ON THE LEFT SIDE OF THE CHILLER AND CH-2 WILL BE OPPOSITE HAND AND WILL HAVE THE CONDENSER WATER BOX ON THE RIGHT, IT WILL BE BENEFICIAL TO BRING CHILLER CH-2 INTO THE PLANT FIRST AND SET IT ON THE EXISTING SUPPORT PAD BEFORE CHILLER CH-1 IS BROUGHT IN. THE DEMOLITION AND INSTALLATION PROCESS WILL BE FAST-TRACKED TO ALLOW ALL FOUR CHILLERS TO BE INSTALLED AT ONE TIME. CHILLER CHILLERS CH-1 AND CH-2 WILL BE TWO PASS EVAPORATOR /CONDENSER MACHINES WITH A CONDENSER WATER-BOX WITH SIDE CONNECTIONS AND STACKED CHILLED WATER SUPPLY AND RETURN FLANGE CONNECTIONS ATTACHED TO THE END OF THE EVAPORATOR BARREL. ALL CONNECTIONS WILL BE ON THE SAME END WITH THE CONDENSER BARREL ON THE LEFT OR RIGHT WHEN FACING

THE MACHINE.

THE EXISTING CHILLERS WILL BE DISMANTLED AS REQUIRED,AND REMOVED THROUGH THE OVERHEAD DOOR IN THE SOUTH EXTERIOR WALL. THE NEW CHILLERS WILL BE BROUGHT INTO THE NORTH PLANT THROUGH THE OVERHEAD DOOR. ONCE INSIDE THE PLANT, THE CHILLER MUST BE ROTATED AND MOVED ONTO THE EXISTING SUPPORT PAD.

A. FOR THE CHILLER CH-1 AND CH-2 REPLACEMENT, ALL PIPING, VALVES, FITTINGS,

CONTROL DEVICES AND OTHER ACCESSORIES WILL BE REMOVED CAREFULLY AND SET

ASIDE AND STORED FOR POSSIBLE REUSE TO INSTALL THE NEW CHILLERS. THE GOAL

WILL BE TO REUSE AS MUCH OF THE EXISTING COMPONENTS AS POSSIBLE.

B. THE EXISTING CONCRETE HOUSE KEEPING PADS WILL BE REUSED TO SUPPORT

THE NEW CHILLERS. ONCE THE CHILLERS ARE REMOVED, THE CONTRACTOR SHALL

REPAIR THE SURFACE OF THE PADS TO PROVIDE A CLEAN MOUNTING SURFACE. DUE

TO THE SIZE OF THE SUPPORT PADS FOR THE NEW CARRIER CHILLERS, THE EXISTING

PADS CAN BE USED AS IS, BUT THE ENDS OF THE NEW CHILLERS MAY EXTEND PAST

THE END EDGES OF THE PADS. IF DESIRED, ADDITIONAL SECTIONS OF PAD CAN BE

ADDED.

C. PLACEMENT OF THE NEW CHILLER ON THE EXISTING PAD WILL BE FIELD

DETERMINED TO MINIMIZE PIPING REMOVAL AND REPLACEMENT WHILE MAINTAINING

MAXIMUM ACCESS SPACE AROUND THE CHILLERS.

NEW CHILLERS WILL BE

THE NEW CHILLERS WILL

NEED TO STAY CLOSE TO

THE WALL SO THAT THEY

WILL SQUEEZE THROUGH

THE SPACE BETWEEN

CHILLER CH-3 AND THE WALL

AS THE NEW CHILLERS MOVE

THROUGH THE SECOND DOOR

OPENING, THE CHILLERS WILL NEED

TO START ROTATING TO MISS THE

WALLS ON THE RIGHT SIDE.

AS THE NEW CHILLERS CONTINUE

TO MOVE NORTH IN THE PLANT, THE

CHILLERS WILL NEED TO CONTINUE

ROTATING TO MISS THE WALLS ON

THE RIGHT SIDE THAT ARE FARTHER

WEST THAT ARE FARTHER WEST

THAN THE SECOND WALL OPENING.

THE FIRST CHILLER TO BE SET WILL BE

CH-1 THAT WILL BE FARTHEST BACK. THE

EXISTING PADS WILL BE UTILIZED AND

SHOULD BE LARGE ENOUGH TO

SUPPORT THE NEW CHILLER FRAME.

THE SECOND CHILLER TO BE SET WILL

BE CH-2 THAT WILL BE CLOSER TO THE

FRONT. ONCE IT IS…
