VHAHOUGolzaY1 Callout

VHAHOUGolzaY1 Text Box VA Revision:

D. CONTRACTOR SHALL COORDINATE CHILLED WATER SYSTEM ISOLATION WITH VA FACILITY PERSONNEL. Contractor shall use localized pipe isolation methods (e.g., mechanical pipe freezing or line-stop fittings) instead of draining and shutting down the full chilled water plant, wherever pipe size, material, and access allow it. Contractor shall submit engineering justification (pipe schedule, pressure rating, and equipment specs for the selected isolation method) for VA approval prior to using this method at each location. If localized isolation is infeasible due to pipe size, access, condition, or system configuration, Contractor shall notify VA and, upon approval, proceed with draining, refilling, and restoring the system, providing water treatment per VA's existing plant water treatment program.

E. CHILLED WATER PLANT ISOLATION FOR VALVE REPLACEMENT: Valve replacement at chiller condenser and evaporator connections shall use localized pipe isolation (e.g., pipe freezing or line-stop fittings) in lieu of a full plant shutdown wherever feasible. Contractor shall coordinate all isolation and replacement activities with VA facility personnel, scheduling work to minimize impact to operations. Final isolation parameters, equipment, and contingency measures shall be submitted by Contractor and approved by VA, and incorporated into the Contractor's work plan. Where VA determines a specific connection cannot be safely isolated by freezing, line-stop, or another non-shutdown method, Contractor shall comply with VA-established shutdown limitations and duration requirements for that limited scope, scheduled during winter months per VA-approved timing.

DESIGN INTENT: PROVIDE A REPLACEMENT CHILLER FULLY INTEGRATED INTO THE

EXISTING CENTRAL PLANT BUILDING AUTOMATION SYSTEM (BAS) CONSISTENT WITH THE

DEPARTMENT OF VETERANS AFFAIRS HVAC DESIGN MANUAL AND THE DOCUMENTED

PLANT CONTROL PHILOSOPHY. THE INTENT IS TO MAINTAIN PLANT RELIABILITY,

REDUNDANCY, AND OPERATIONAL CONSISTENCY WHILE AVOIDING THE INTRODUCTION

OF SPECIAL-CASE OR NON-STANDARD CONTROL LOGIC.

1. GENERAL REQUIREMENTS

CHILLER #1 SHALL BE INTEGRATED INTO THE EXISTING BAS AND SHALL OPERATE AS

PART OF THE BASE PLANT CHILLER GROUP. CONTROL SEQUENCES SHALL BE

CONSISTENT WITH THOSE APPLIED TO THE REMAINING CHILLERS SERVING THE

CENTRAL PLANT.

THE REPLACEMENT CHILLER SHALL NOT REQUIRE UNIQUE OR STANDALONE BAS LOGIC.

ALL CONTROL FUNCTIONS SHALL BE COORDINATED THROUGH THE EXISTING BAS AND

SHALL CONFORM TO ESTABLISHED PLANT SEQUENCING, STAGING, AND ALARM

STRATEGIES.

2. BAS COMMUNICATIONS AND POINTS

THE REPLACEMENT CHILLER SHALL BE PROVIDED WITH BACNET COMMUNICATION

COMPATIBLE WITH THE EXISTING BAS. THE FOLLOWING MINIMUM POINTS SHALL BE

PROVIDED:

CHILLER ENABLE/DISABLE

CHILLER RUN STATUS

CHILLER ALARM/FAULT STATUS

ENTERING AND LEAVING CHILLED WATER TEMPERATURES

CHILLER ELECTRICAL DEMAND (KW) AND EFFICIENCY INDICATION, WHERE

AVAILABLE

CHILLER AVAILABILITY STATUS

ALL POINT NAMING CONVENTIONS, ALARM PRIORITIES, AND TRENDING INTERVALS SHALL

MATCH EXISTING CHILLER INTEGRATIONS.

3. CHILLER ENABLE AND STAGING

THE BAS SHALL ENABLE CHILLER #1 BASED ON SYSTEM LOAD DEMAND, LEAD/LAG

ASSIGNMENT, AND OPERATOR-DEFINED SCHEDULES.

UPON RECEIPT OF AN ENABLE COMMAND, THE CHILLER SHALL EXECUTE INTERNAL

START PERMISSIVES AND SAFETY CHECKS IN ACCORDANCE WITH THE

MANUFACTURER’S FACTORY CONTROL SEQUENCE. SUCCESSFUL OPERATION SHALL BE

VERIFIED BY BAS MONITORING OF RUN STATUS.

IF CHILLER #1 FAILS TO START OR EXPERIENCES A FAULT, THE BAS SHALL GENERATE AN

ALARM AND AUTOMATICALLY ADVANCE TO THE NEXT AVAILABLE CHILLER IN THE

STAGING SEQUENCE.

4. CHILLED WATER SYSTEM INTERLOCKS

CHILLER #1 OPERATION SHALL BE INTERLOCKED WITH CHILLED WATER FLOW PROOF AND

ASSOCIATED ISOLATION VALVE STATUS. BUTTERFLY VALVES ONLY. SPECIFIED GATE VALVES

ARE FOR MANUAL LOCKOUT ONLY.

PROOF OF CHILLED WATER FLOW SHALL BE REQUIRED PRIOR TO THE BAS CONSIDERING

THE CHILLER AVAILABLE FOR LOADING. LOSS OF CHILLED WATER FLOW SHALL RESULT IN

CHILLER SHUTDOWN AND BAS ALARM.

5. CONDENSER WATER SYSTEM INTERLOCKS

CONDENSER WATER FLOW SHALL BE PROVEN PRIOR TO CHILLER ENABLE. THE BAS SHALL

COORDINATE CONDENSER WATER PUMPS AND COOLING TOWER OPERATION TO SUPPORT

CHILLER #1 CONSISTENT WITH EXISTING PLANT LOGIC.

6. CAPACITY CONTROL AND PLANT OPTIMIZATION

CHILLER CAPACITY MODULATION SHALL BE PERFORMED BY THE CHILLER’S INTERNAL

CONTROLS. THE BAS SHALL MANAGE OVERALL PLANT PERFORMANCE THROUGH CHILLED

WATER SUPPLY TEMPERATURE CONTROL AND CHILLER STAGING.

CHILLER #1 SHALL PARTICIPATE IN ALL APPLICABLE PLANT OPTIMIZATION ROUTINES,

INCLUDING LEAD/LAG ROTATION AND DEMAND-BASED STAGING, CONSISTENT WITH EXISTING

CHILLERS.

7. ALARMS AND SAFETIES

ALL CHILLER ALARMS AND SAFETY SHUTDOWNS SHALL BE ANNUNCIATED AT THE BAS.

ALARM PRIORITIES SHALL BE CONSISTENT WITH EXISTING CHILLER ALARM CLASSIFICATIONS.

UPON A SAFETY TRIP OR FAULT CONDITION, CHILLER #1 SHALL BE DESIGNATED

UNAVAILABLE AND REMOVED FROM AUTOMATIC STAGING UNTIL CLEARED.

8. MANUAL CONTROL AND MAINTENANCE MODES

THE BAS SHALL PROVIDE OPERATOR-SELECTABLE MANUAL ENABLE/DISABLE CONTROL FOR

CHILLER #1. A MAINTENANCE LOCKOUT FUNCTION SHALL BE PROVIDED TO REMOVE THE

CHILLER FROM AUTOMATIC STAGING WITHOUT AFFECTING PLANT OPERATION.

9. REDUNDANCY AND RELIABILITY

CHILLER #1 SHALL BE INCLUDED IN THE PLANT LEAD/LAG ROTATION TO SUPPORT

REDUNDANCY AND EVEN EQUIPMENT RUN-TIME DISTRIBUTION. BAS LOGIC SHALL

AUTOMATICALLY MAINTAIN REQUIRED CHILLED WATER CAPACITY IN THE EVENT CHILLER #1

IS UNAVAILABLE.

10. TESTING AND COMMISSIONING

FUNCTIONAL PERFORMANCE TESTING SHALL VERIFY BAS INTEGRATION, ENABLE/DISABLE

LOGIC, SAFETIES, ALARMS, AND STAGING COORDINATION IN ACCORDANCE WITH VA

COMMISSIONING REQUIREMENTS.

REMOVE ALL EXISTING WIRING DEVICES, LIGHT FIXTURES, WIRE, CONDUIT, ETC., AS NOTED OR INDICATED WITHIN DEMOLITION AREA (ALL ITEMS MAY NOT BE SHOWN). REWORK, AS NECESSARY, CIRCUITING WHICH

REQUIRES CONTINUATION THROUGH THE AREA.

ELECTRICAL CONTRACTOR TO PROVIDE ALL NECESSARY LABOR, CONDUIT, WIRE, CONNECTIONS, ETC., FOR DEVICES, FIXTURES, ETC., NOTED AS "EXISTING TO REMAIN" SUCH THAT EXISTING CIRCUIT CONTINUITY IS

MAINTAINED.

ELECTRICAL CONTRACTOR SHALL BE RESPONSIBLE FOR ALL WORK REQUIRED TO REMOVE/RELOCATE ANY EXISTING ELECTRICAL EQUIPMENT SUCH THAT ELECTRIC SHOCK HAZARDS TO WORKMEN ARE ELIMINATED

DURING DEMOLITION AND NEW CONSTRUCTION.

ELECTRICAL CONTRACTOR SHALL BE RESPONSIBLE FOR ALL WORK IN REMOVING AND REPLACING "EXISTING TO REMAIN" FIXTURES, DEVICES, ETC., AS REQUIRED SO THAT THESE DEVICES ARE NOT DAMAGED DURING DEMOLITION. RELOCATED TO NEAREST APPROPRIATE LOCATION TO AVOID CONFLICTS WITH OTHER TRADES' WORK. REPLACE WITH NEW ANY "EXISTING TO REMAIN" FIXTURE, DEVICE, ETC., NOT DEEMED SALVAGEABLE

BY THE COR.

REMOVED OR DAMAGED CONDUIT, WIRE, AND FITTINGS SHALL NOT BE REUSED FOR RELOCATED OR NEW

DEVICES.

MAKE AS-BUILTS WITH NEW TYPED DIRECTORIES FOR ALL PANELBOARDS, INDICATING CIRCUIT DESCRIPTION

(USED OR SPARE), CIRCUIT BREAKERS AND CIRCUIT LOAD.

WORK REQUIRED FOR EXISTING EQUIPMENT NOTED AS "EXISTING TO BE REMOVED" SHALL INCLUDE:

REMOVAL OF FEEDER FROM EQUIPMENT TO POINT OF FEED.

REMOVAL OR RE-CIRCUITING OF ALL BRANCH CIRCUITING.

REMOVAL OF ALL FITTINGS, SUPPORTS, BRACKETS, ETC.

PATCHING OF WALLS, FLOORS, CEILINGS, EARTH, PAVEMENT AND CONCRETE, PER ARCHITECT'S

INSTRUCTIONS.

CAPPING OF FEEDER CONDUIT AT 6" ABOVE OR BELOW FLOOR/CEILING AS REQUIRED AND MARKING

LOCATION OF POINT OF FEED WITH AN ENGRAVED BRASS TAG.

REMOVAL OF FEEDER CONDUIT IF FOUND TO BE UNSALVAGEABLE BY ARCHITECT, ENGINEER OR THE

COR.

EXISTING EQUIPMENT NOT IMPLICITLY SHOWN ON THE DRAWINGS IS INTENDED TO BE "EXISTING TO REMAIN
