Amendment 0002 7440851 Replace Chiller & Cooling Tower B4225

RFI Responses:

A. This amendment provides responses to pre-proposal inquiries:

1. MCAS CP FRCS Standardization (Attached): In accordance with MCAS CP FRCS Standardization for JCI Metasys branded products, please include “J&A ML-25-03 Class FRCS Cherry Point” within the next amendment

Response: Concur.

2. Chilled Water Control Points: M-702 shows several writeable outputs and control dependent inputs via network connection. This will not provide reliable control if network connection is lost. Revise all writeable outputs and the control dependent inputs to be hardwired to JCI Metasys controller

Response: M-702 revised as requested. See attached updated M-702 drawing (NAVFAC # 12939367)

3. BTU Meter: M-702 shows a BTU meter being installed. For cost savings, the 2 temperature sensors and 1 flow meter shown on M-702 could be used to calculate BTU within JCI Metasys controller. Please confirm removal of BTU meter hardware.

Response: Non-concur. TS-1 and TS-2 measure temperature out to system while FMS-1 measures plant flow on other side of bypass valve for ensuring chiller min flow is maintained.

Provide BTU meter per drawings.

4. Control drawing M-702 indicates that there is a heat trace controller included in the project however neither the mechanical drawings (including sequence of operation) nor the electrical drawings stipulate the provision of a heat trace controller or the power wiring for it. Please confirm whether a heat trace controller is included in the project and if so, revise the mechanical and electrical drawings accordingly.

Response: Heat trace controller identified on E-401 and noted to be provided on mechanical sheet M-402 keynote 5 and per detail 7/M-501. Provide evaporator low ambient heater per chiller schedule note I on M-601. Coordinate exact power requirements with chiller manufacturer. Reference amendment 2 electrical modification identifying an additional dedicated power connection for chiller low ambient kit evaporator heater. Field provided heat trace must extend to limits of factory installed systems to avoid gapping of heat trace freeze protection.

5. The chiller schedule indicates a full load capacity of 290.5 tons at 55°F EWT, 44°F LWT, and 655 GPM. Our proposed chiller provides 290.5 tons at 55°F EWT, 44°F LWT, and 632.1 GPM. Will this be acceptable? Based on the scheduled flow rate of 655 GPM and an 11°F temperature differential, the calculated load is approximately 300 tons, which exceeds the scheduled full load capacity of 290.5-tons.

Response: The proposed flow rate is acceptable.

Amendment 0002 7440851 Replace Chiller & Cooling Tower B4225

B. This amendment incorporates the following attachments:

1. NAVFAC DWG NO. M-702, E-401, E,403, and E-601

C. All other contract terms and conditions remain unchanged.

DESIGN INTENT

THE CHILLED WATER SYSTEM IS AN AIR-COOLED CHILLER PLANT WITH VARIABLE PRIMARY PUMPING SYSTEM. THE

CHILLERS ARE IN A LEAD-LAG OPERATION AND PUMPS HAVE N+1 REDUNDANCY.

THE CHILLED WATER PLANT SERVES THE BUILDING HVAC EQUIPMENT. THE HVAC SYSTEM CONSISTS OF MULTIPLE

ROOFTOP AIR HANDLER UNITS AND AIR HANDLER UNITS 2-WAY COOLING COILS.

GENERAL

IF REQUIRED BY THE CHILLER MANUFACTURER'S WRITTEN INSTRUCTIONS, PROVIDE DIFFERENTIAL PRESSURE TRANSMITTER DPT-X. WHEN THE PRESSURE DROP ACROSS THE CHILLER MEETS THE PRESSURE DROP ASSOCIATED WITH THE CHILLER MANUFACTURER'S REQUIRED MINIMUM FLOW THE CHILLER WILL BE ENABLED TO START.

UPON PROOF OF FLOW IN ACCORDANCE WITH CHILLER MANUFACTURER'S WRITTEN INSTRUCTIONS, THE SELF CONTAINED CHILLER CONTROLS WILL START AND MODULATE THE CHILLER CAPACITY TO MAINTAIN SETPOINT.

DISPLAY BTUM-1 TONNAGE, CHILLED WATER FLOW RATE (GPM), AND TEMPERATURES ON GRAPHIC.

RECORD INSTANTANEOUS TOTAL PLANT POWER (KW), PLANT PRODUCTION (TONS) AND CHILLED WATER FLOW (GPM) EVERY 5 MINUTES. INSTANTANEOUS TOTAL PLANT POWER (KW) IS THE SUM OF THE TOTAL KW FROM OPERATING CHILLERS, AND CHILLED WATER PUMPS. CHILLED WATER PUMP KW IS BASED UPON MEASURED

CURRENT FROM TAB REPORT.

MONTHLY PRODUCTION REPORT: FOR A SPECIFIED 24 MONTH PERIOD, BY MONTH, DISPLAY: TOTAL GALLONS, TOTAL TON-HOURS, TOTAL KWH, AVERAGE KW/TON, AVERAGE GPM, AND AVERAGE OUTSIDE AIR TEMPERATURE. PROVIDE

A BUTTON ON THE GRAPHICS TO GENERATE AND VIEW THE REPORT.

HOURLY PRODUCTION REPORT: FOR A SPECIFIED 24 HOUR PERIOD, BY HOUR, DISPLAY: TOTAL GALLONS, TOTAL TON-HOURS, TOTAL KWH, AVERAGE KW/TON, AND AVERAGE GPM. PROVIDE A BUTTON ON THE GRAPHICS TO

GENERATE AND VIEW THE REPORT.

CHILLER

CHILLED WATER SYSTEM START / STOP: THE CHILLED WATER SYSTEM WILL BE ENABLED TO START AND STOP BY

THE BAS. THERE IS NO TIME DELAY DURING OPTIMUM START AND OPTIMUM STOP.

ON A CALL FOR THE CHILLED WATER SYSTEM TO START, OPEN LEAD CHILLER VALVE V-CH-X. START LEAD CHILLED

WATER PUMP AND ENABLE LEAD CHILLER.

ON COMMAND TO START A SECOND CHILLER, START ASSOCIATED PUMP AND OPEN CHILLER VALVE V-CH-X PRIOR TO ENABLING LAG CHILLER. UPON PROOF OF FLOW, ENABLE LAG CHILLER. ON COMMAND TO STOP THE SECOND, THE REVERSE WILL OCCUR.

THE OWS WILL COMMAND AN ADDITIONAL CHILLER ON WHEN CHILLED WATER SUPPLY TEMPERATURE AS SENSED BY TEMPERATURE TRANSMITTER TS-1 IS 1.5 DEGREES F ABOVE PLANT CHILLED WATER SETPOINT CONTINUOUSLY FOR

15 MINUTES, OR

THE OWS WILL COMMAND A CHILLER OFF WHEN ALL OF THE FOLLOWING OCCUR:

1. CHILLER CAPACITY IS NOT NEEDED: WHEN THE TOTAL ELECTRICAL DEMAND (SUM OF KW OR AMPERES) IS 90% OF A SINGLE CHILLER ELECTRICAL DEMAND, TURN OFF THE SECOND CHILLER.

2. IF THE MEASURED FLOW AT FMS-1 IS LESS THAN 590 GPM WHEN BOTH CHILLERS ARE RUNNING.

PROVIDE A ONE HOUR DELAY BETWEEN STARTING AND STOPPING OF CHILLERS.

WHEN THE FIRST CHILLED WATER PUMP IS AT MAXIMUM SPEED AND UPON A CONTINUED FALL IN DIFFERENTIAL PRESSURE AT DPT-CW BELOW SETPOINT, SEND ALARM TO OWS. THE SECOND PUMP WILL START UPON OPERATOR MANUAL APPROVAL AT OWS. UPON A FALL IN PUMP SPEED TO 75%, THE SECOND PUMP WILL STOP. PROVIDE A 15 MINUTE TIME DELAY BETWEEN PUMP STARTS AND STOPS. IF OPERATING, STOP LAG PUMP EACH NIGHT AT 2000

HOURS.

THE SELF-CONTAINED CHILLER CONTROLS WILL MODULATE THE CHILLER CAPACITY TO MAINTAIN PLANT CHILLED

WATER SETPOINT.

ON A CALL FOR THE CHILLED WATER SYSTEM TO STOP, STOP ALL CHILLERS AND PUMPS AND RETURN ALL VALVES

TO THE NORMAL POSITION.

LEAD/LAG SELECTION

THE SELECTION OF THE LEAD AND LAG CHILLED WATER PUMPS AND CHILLERS WILL BE MADE MANUALLY AT THE OWS. THE LEAD/LAG EQUIPMENT WILL ALTERNATE AUTOMATICALLY BASED ON EQUIPMENT ROTATION PARAGRAPH

BELOW.

CHILLERS AND PUMPS INPUT AS "OUT OF SERVICE" WILL BE SKIPPED OVER IN THE STARTING AND STOPPING

SEQUENCE.

EQUIPMENT ROTATION: AUTOMATICALLY ALTERNATE THE FOLLOWING TO EQUALIZE THE RUN TIMES, WITH A

MINIMUM OF ONCE PER WEEK:

CHILLED WATER PUMPS CWP-1, CWP-2, AND CWP-3 AND CHILLER CH-1 AND CH-2

PUMPS

LEAD PUMP START/STOP: THE LEAD CHILLED WATER PUMP WILL BE STARTED BY THE BAS WHEN THE CHILLER IS

ENABLED. THE PUMP WILL BE STOPPED WHEN THE CHILLER IS DISABLED.

PUMP SPEED: ON A FALL IN SYSTEM DIFFERENTIAL PRESSURE BELOW SETPOINT (INITIAL 40' W.G., SEE NOTE 1), AS SENSED BY DPT-CW, THE PUMP SPEED WILL INCREASE. ON A RISE IN PRESSURE THE REVERSE WILL OCCUR.

CHILLED WATER BYPASS VALVE V-1 WILL BE MODULATED TO MAINTAIN A MINIMUM FLOW THROUGH THE OPERATING CHILLER AS MEASURED BY FLOW METER FMS-1. CONFIRM MINIMUM FLOW WITH MANUFACTURER. UPON ACTIVATION OF LAG CHILLER, VALVE V-1 SETPOINT WILL INCREMENT TO CUMULATIVE MINIMUM FLOW OF BOTH CHILLERS.

RESETS: WHEN THE MOST DEMANDING CHILLED WATER VALVE IS 85% OPEN OR LOWER FOR 5 MINUTES, CHILLED WATER DIFFERENTIAL PRESSURE SETPOINT WILL BE RESET LOWER, IN ACCORDANCE WITH ASHRAE 90.1. WHEN THE MOST DEMANDING VALVE IS 95% OPEN OR HIGHER FOR 5 MINUTES, THE REVERSE WILL OCCUR.

PUMP ROTATION: ON A FAILURE OF THE LEAD PUMP, THE LAG PUMP WILL BE STARTED AND AN ALARM INDICATED AT
