MECHANICAL – DEMOLITION NOTES

MECHANICAL DEMOLITION DRAWINGS SHOWING EXISTING CONDITIONS HAVE BEEN

PREPARED BASED ON NON-DESTRUCTIVE FIELD OBSERVATION AND AS-BUILT DRAWINGS

PROVIDED BY THE OWNER. FIELD VERIFY EXISTING SYSTEMS BEFORE BEGINNING WORK.

NOTIFY ARCHITECT/ENGINEER IF EXISTING CONDITIONS ARE MATERIALLY DIFFERENT THAN

THOSE SHOWN ON THE PLANS.

BE FAMILIAR WITH EXISTING MECHANICAL SYSTEMS THAT WILL BE AFFECTED BY THE

DEMOLITION WORK. OBTAIN PERMISSION FROM THE OWNER'S REPRESENTATIVE TO SHUT

OFF SERVICES OR SYSTEMS THAT AFFECT AREAS BEYOND THE LIMITS OF THE IMMEDIATE

DEMOLITION AREA. INFORM THE OWNER’S REPRESENTATIVE OF THE REASON FOR AND

DURATION OF THE SHUTDOWN. MINIMIZE IMPACT TO OTHER AREAS. PROCEED WITH THE

SHUT-DOWN AFTER PERMISSION FROM THE OWNER IS GRANTED.

REMOVE PIPING, HANGERS, DUCTWORK, GRILLES, REGISTERS, DIFFUSERS, ETC. THAT ARE

INDICATED TO BE REMOVED IN A TIMELY MANNER IN ACCORDANCE WITH THE GENERAL

DEMOLITION SPECIFICATIONS. COORDINATE WITH THE OWNER AND OTHER CONTRACTORS.

UNLESS EQUIPMENT TO BE REMOVED IS NOTED AS OWNER’S SALVAGE, DISPOSE OF

EQUIPMENT AND/OR MATERIALS INDICATED TO BE REMOVED PROMPTLY.

REMOVE ALL ABANDONED PIPING AND DUCTWORK THAT IS EXPOSED OR ACCESSIBLE

WITHOUT WALL OR CEILING DEMOLITION.

HVAC - NOTES

COORDINATE WORK WITH ALL OTHER TRADES AS DESCRIBED IN MECHANICAL GENERAL

NOTE #1.

INSTALL ALL EQUIPMENT PER MANUFACTURER'S RECOMMENDATIONS. INSTALL SYSTEM TO

MEET ALL CITY AND STATE CODES AND REQUIREMENTS.

CONTINUE PIPE INSULATION THROUGH WALLS, FLOORS, AND CEILING PENETRATIONS

UNBROKEN. SEAL AROUND INSULATION AT WALL PENETRATIONS.

MECHANICAL - GENERAL NOTES

COORDINATE MECHANICAL AND ELECTRICAL WORK WITH ALL OTHER TRADES. BEGIN

INSTALLATION AND ROUGH-IN AFTER COORDINATION WITH ALL TRADES ASSOCIATED WITH

THE INSTALLATION IS COMPLETE. COORDINATE BUILDING STRUCTURE, ARCHITECTURAL

ASSEMBLIES, SHEET METAL, ALL PIPING SYSTEMS, LIGHT FIXTURES, CONDUITS, CABLE

TRAYS, ETC. REFER TO ALL GENERAL, MECHANICAL, AND ELECTRICAL DRAWINGS AND

SPECIFICATIONS FOR THIS PROJECT. CONTRACTOR IS RESPONSIBLE FOR REWORK

ASSOCIATED WITH FAILURE TO COORDINATE.

INCORPORATE MECHANICAL SPECIFICATIONS, DRAWINGS, STATE AND LOCAL CODES INTO

WORK.

EACH TRADE IS RESPONSIBLE FOR MAKING PENETRATIONS WHERE REQUIRED IN EXISTING

WALLS, FLOORS, CEILINGS, AND ROOFS. MAKE PENETRATIONS NEAT. PATCH, CONCEAL, OR

CAULK OVERCUT.

COVER EXPOSED WALL PENETRATIONS WITH ESCUTCHEONS OR SHEET METAL AS

APPROPRIATE.

CAULK ALL CONCEALED AND EXPOSED PIPING AND DUCT WALL PENETRATIONS TO PREVENT

NOISE TRANSFER BETWEEN SPACES.

CREATE OPENINGS IN THE BUILDING THAT ARE REQUIRED TO REMOVE EXISTING ITEMS AND

TO BRING IN NEW EQUIPMENT. PATCH ALL OPENINGS CREATED AND FINISHED WITH

MATERIALS TO MATCH EXISTING CONDITIONS. INCLUDE THIS WORK IN BID.

ON COMPLETION OF THE INSTALLATION, COOPERATE WITH THE OWNER TO PROVIDE

TESTING, ADJUSTING, AND BALANCING TO OBTAIN PROPER OPERATION OF ALL EQUIPMENT

AND SYSTEMS. PROVIDE ALL FACILITIES AND EQUIPMENT AND COMPLETE ALL TESTS

REQUIRED FOR ADJUSTMENTS AND BALANCING TO ESTABLISH THE PROPER PERFORMANCE

OF EQUIPMENT.

PROVIDE WARRANTIES FOR ALL EQUIPMENT AND INSTALLATION PER THE CONTRACT

DOCUMENTS. CONDITIONING REFRIGERATION SYSTEMS SHALL BE WARRANTED FOR A

MINIMUM OF 5 YEARS, PARTS ONLY, NON-PRORATED, FROM THE DATE OF OCCUPANCY OR

SUBSTANTIAL COMPLETION, OR WHICHEVER OCCURS FIRST. THE WARRANTY SHALL COVER

COMPRESSORS, EVAPORATORS, CONDENSER COILS, HIGH AND LOW SIDE PIPING, AND

PIPING SPECIALTIES INCLUDING EXPANSION AND SOLENOID VALVES, RELIEF VALVES, FILTER-

DRYER, AND SIGHT GLASSES. PRESSURE GAUGES AND PRESSURE SWITCHES ARE NOT

UNDER THE EXTENDED WARRANTY EXCEPT FOR LOSS OF REFRIGERANT AND

CONSEQUENTIAL DAMAGE TO THE SYSTEM WHICH WILL BE AN EXTENDED WARRANTY

OBLIGATION. ALL DEFECTS THAT BECOME APPARENT WITHIN THE WARRANTY PERIOD SHALL

BE REPAIRED BY THE MECHANICAL CONTRACTOR AS DIRECTED BY THE ENGINEER THROUGH

THE OWNER’S REPRESENTATIVE. WARRANTY DOES NOT OBLIGATE THE MECHANICAL

CONTRACTOR TO REPAIR DAMAGE RESULTING FROM THE OWNER’S ACCIDENT, IMPROPER

OPERATION, OR FAILURE TO PROVIDE MAINTENANCE. WARRANTY COVERS DEFECTIVE

MATERIAL AND INSTALLATION. REFER TO SPECIFICATIONS FOR ADDITIONAL DETAILS AND

CHILLER WATER PUMP OPERATION:

WHEN THE COOLING SYSTEM IS MANUALLY ENABLED AT THE DDC, THE CHILLED WATER PUMP SHALL BE ENABLED AND SHALL RUN CONTINUOUSLY. PUMP SPEED SHALL BE

ESTABLISHED BY THE TAB CONTRACTOR. SYSTEM HAS FULLY REDUNDANT CHILLERS/PRIMARY PUMPS THAT SHOULD BE USED IN ALTERNATING SCHEDULE DETERMINED

BY THE OWNER.

CHILLER OPERATION:

THE CHILLER SHALL BE CONTROLLED BY THE LOCAL CONTROLLER. THE CHILLER CONTROLLER WILL MODULATE AND ADJUST COMPRESSOR STAGING, CONDENSER FAN

OPERATION, HOT GAS BYPASS CONTROL TO ACHIEVE CHILLED WATER SUPPLY SETPOINT, THE DRY COOLER WILL BE CONTROLLED BY THE DDC. WHEN THE COOLING

SYSTEM IS MANUALLY ENABLED AT THE DDC, THE FOLLOWING SEQUENCE WILL OCCUR:

•

CHILLED WATER PUMP WILL START

•

CHILLED WATER FLOW SWITCH WILL BE SET

•

CHILLED WATER SETPOINT WILL BE SET TO 44F (ADJ.).

•

AFTER A 10 MIN. WAIT, CHILLER WILL BE ENABLED.

WHEN THE COOLING SYSTEM IS MANUALLY DISABLED AT THE DDC, THE FOLLOWING SEQUENCE WILL OCCUR:

•

AFTER A 10 MIN. WAIT, CHILLER WILL BE DISABLED.

•

AFTER A 20 MIN. WAIT, CHILLED WATER PUMP TO BE STOPPED.

ADDITIONAL COOLING MODE:

•

IF CHILLED WATER SETPOINT IS NOT ABLE TO BE MAINTAINED FOR 20 MIN. (ADJ.) WITH ENABELED CHILLER FULLY LOADED, THEN REDUNDANT CHILLER SHALL BE

ENABLED AND BOTH CHILLERS SHALL MODULATE TO MAINTAIN SETPOINT. AFTER CHILLED WATER SETPOINT HAS BEEN MAINTAINED FOR 30 MIN., REDUNDANT

CHILLER SHALL BE DISABLED AND RETURN TO ALTERNATING SCHEDULE.

LOW TEMPERATURE OPERATION:

•

IF O.A. TEMP IS BELOW 25F (ADJ.) FOR 15 MIN. (ADJ.) THEN DRY COOLER 3-WAY VALVE AND FANS SHALL MODULATE TO MAINTAIN SETPOINT.

WHEN O.A. TEMP RISES ABOVE 28F (ADJ.) FOR 1 HOUR (ADJ.), MODULATE 3-WAY VALVE BETWEEN BYPASS AND FULL FLOW THROUGH DRY COOLER AS REQUIRED TO

MAINTAIN SETPOINT.

EXISTING BUFFER TANK BYPASS VALVE CONTROL. PROVIDE ABILITY ON USER INTERFACE TO MANUALLY OPEN BYPASS VALVE FOR BUFFER TANK. NORMAL OPERATION IS

TO HAVE CLOSED.

EXISTING ISOLATION CONTROL VALVES SHALL REMAIN AND BE USED AS NEEDED TO ISOLATE EACH CHILLER IF SERVICE IS NEEDED. CHILLERS CAN ALSO BE ISOLATED

MANUALLY VIA MANUAL VALVES.

TRENDS

ALL POINTS SHALL BE HISTORICALLY TRENDED. TREND POINTS EVERY 15 MIN OVER A 365 DAY PERIOD OF TIME.

FLOW METER SHOWN SHALL BE USED TO VERIFY FLOW AND CALCULATE APPROXIMATE CURRENT TONNAGE ON USER INTERFACE.

ALARMS AND INTERLOCK SAFETIES:

THE FOLLOWING SHALL SHUT DOWN THE ENABLED CHILLER AND PUMP AND SHALL INDICATE AN ALARM CONDITION. DDC SHALL ENABLE REDUNDANT CHILLER AND PUMP:

- PUMP STATUS CAN NOT BE VERIFIED WITH CURRENT RELAY (AUTO RESET)

- FLOW SWITCH CAN NOT BE VERIFED (AUTO RESET)

THE FOLLOWING SHALL DISABLE THE ENABLED PUMP AND SHALL INDICATE AN ALARM CONDITION. DDC SHALL ENABLE REDUNDANT PUMP.

- PUMP STATUS CAN NOT BE VERIFIED WITH CURRENT RELAY (AUTO RESET)

ALARMS

THE FOLLOWING SHALL INDICATE AN ALARM CONDITION:

- A GENERAL VFD ALARM

- A GENERAL CHILLER ALARM

- CHILLED WATER SUPPLY TEMPERATURE IS > OR < 5°F FROM SETPOINT FOR MORE THAN 10 MIN.

COOLING SYSTEM REPORT GENERATION:

BAS SHALL MONITOR THE FOLLOWING POINT ON 5 MIN. (ADJ.) INTERVALS WITH SIGNAL TREND. THE TREND SHALL RUN FOR A 365 DAY (ADJ.)

DURATION AT WHICH POINT THE NEWEST VALUES SHALL OVERWRITE THE OLDEST VALUES:

•

DATE

•

TIME

•

GLOBAL OUTSIDE AIR TEMP. (F)

•

SYSTEM CHILLED WATER SUPPLY TEMP (F)

•

SYSTEM CHILLED WATER SUPPLY TEMP SETPOINT (F)

•

•

SYSTEM CHILLED WATER FLOW RATE (GPM)

•

COOLING SYSTEM LOAD (TONS)

•

OPERATIONAL STATUS OF CHILLER, CHILLED WATER PUMP.

THIS INFORMATION SHALL BE ACCESSIBLE TO VIEW IN NEITHER TABULAR OR GRAPHICAL FORM ON THE BAS.

ONCE PER MONTH THE BAS SHALL RECORED THE LARGEST COOLING SYSTEM LOAD (IN TONS) WHICH OCCURED DURING THAT MONTH,

THE DATE, TIME, OUTSIDE AIR TEMPERATURE, CHILLED WATER SUPPLY AND RETURN TEMPERATURES WHICH COINCIDED WITH THAT EVENT

SHALL ALSO BE RECORDED. THIS INFORMATION SHALL BE STORED TO A MEMORY LOCATION ON THE BAS OPERATOR INTERFACE THAT IS MAINTAINED

(NOT AUTOMATICALLY OVERWRITTEN).
