2. THE CONSTRUCTION PHASING SEQUENCE IS MEANT AS A DESIGN INTENT. CONTRACTOR IS RESPONSIBLE FOR PROVIDING A DETAILED STEP BY STEP CONSTRUCTION PHASING SEQUENCE AND SUBMIT

TO THE VA COR AND A&E FOR APPROVAL.

3. IN CASE OF ANY DISCREPANCIES BETWEEN THE NARRATIVE BELOW, DRAWINGS OR SPECS, A RFI SHALL BE GENERATED BY THE CONTRACTOR TO THE DESIGN TEAM. THE NARRATIVE BELOW MAY OR

MAY NOT CONTAIN ALL THE DETAILS LISTED ELSEWHERE ON THE DRAWINGS/SPECS, REFER TO DRAWINGS/SPECS FOR MORE INFORMATION.

4. CONTRACTOR TO COORDINATE WITH LOCAL DIESEL DELIVERY COMPANIES TO ENSURE THAT FUEL DELIVERY TRACKS AREA AVAILABLE ON STANDBY TO ENSURE THAT FUEL OIL IS AVAILABLE AT ALL

TIMES TO FILL THE EXISTING GENERATOR BELLY TANKS DURING SHUTDOWNS.

PHASE 2 - INSTALL TEMPORARY BOILERS

THE INTENT OF PHASE 2 IS TO INSTALL TEMPORARY BOILERS PRIOR TO DEMOLITION OF THE EXISTING BOILERS OR ANY PHASE 32 WORK SO THERE IS NO DISRUPTION TO FACILITY OPERATIONS.

THE BASIS OF DESIGN FOR THE TEMPORARY BOILERS IS POWERHOUSE. THE TEMPORARY BOILERS HAVE THE CAPACITY TO HANDLE THE FACILITY STEAM LOADS FOR BOTH WINTER AND SUMMER AS INDICATED ON THE DRAWINGS. EACH BOILER WILL HAVE THE CAPABILITY TO HAVE DUEL FUELS (NATURAL GAS AND #2 FUEL OIL) AND WILL HAVE A DA TANK, CHEMICAL SYSTEM AND OTHER ANCILLARY EQUIPMENT. PRESSURE RELIEF VALVE WILL BE INSTALLED ON 8” HPS IN CHILLER PLANT AND TIED INTO EXISTING 10” MAIN VENT STACK. PRESSURE RELIEF VALVE WILL BLOW OFF STEAM TO MAIN VENT

STACK DURING LOW SUMMER LOAD.

A CONTROL TRAILER WILL BE INSTALLED ADJACENT TO THE TEMPORARY BOILER TRAILERS. THE CONTROL TRAILER WILL CONTAIN SINK, CONTROLLERS, SCREENS AND A REST ROOM. THE REST ROOM AND

SINK WILL BE PUMPED OUT ON A WEEKLY BASIS.

PREPARATION WORK MUST BE CONDUCTED IN ORDER TO OPERATE THE TEMPORARY BOILERS. THE PREPARATION WORK INCLUDES:

1. UTILITY TIE-INS TO EXISTING FACILITY UTILITIES

2. MODIFICATION OF THE NATURAL GAS AUTOMATIC SHUT-OFF VALVE

3. REMOVE NATURAL GAS LINE TO BOILER #1.

4. INSTALL TEMPORARY NATURAL GAS SERVICE FOR TEMPORARY BOILERS.

5. INSTALL TEMPORARY WATER SERVICE FOR TEMPORARY BOILERS.

6. INSTALL NEW TEMPORARY MEDICAL GAS CABINETS AND ALARMS IN TEMPORARY CONTROL ROOM.

7. MODIFICATION OF THE STEAM HEADER PIPING IN THE BOILER PLANT.

8. MODIFICATION OF THE EXISTING CONDENSATE SYSTEM.

9. EXISTING DOMESTIC WATER HEATERS WILL BE REPLACED.

10. EXISTING AHU VFD WILL BE RELOCATED.

11. EXISTING COMPRESSORS WILL BE RETROFITTED WITH A LEAD/LAG CONTROLS. PRESSURE ALARM WILL BE EXTENDED TO THE TEMPORARY CONTROL ROOM.

12. EXISTING MAIN GAS VALVE ALARM WILL BE EXTENDED TO THE TEMPORARY CONTROL ROOM

13. EXISTING HIGH PRESSURE STEAM UNIT HEATERS WILL BE REPLACED.

14. EXISTING WINTER BOILER FUEL OIL PUMPS WILL BE REPLACED.

15. INSTALLATION OF PROTECTIVE PARTITIONS, A DUST BARRIER ENCLOSURE TO PROTECT EXISTING EQUIPMENT IN THE BOILER PLANT

THE UTILITIES INCLUDING NATURAL GAS, DIESEL FUEL OIL, CONDENSATE PIPING, ELECTRIC, DDC CONTROLS, AND WATER MUST BE CONNECTED TO THE TEMPORARY BOILERS. SHUTDOWNS WILL BE REQUIRED. IN ADDITION, THE STEAM PIPING FROM THE TEMPORARY BOILERS SHALL BE CONNECTED TO THE EXISTING STEAM HEADER VIA A CONNECTION POINT IN THE EXISTING CHILLER PLANT. THIS

CONNECTION POINT WILL PROVIDE STEAM TO THE FACILITY.

THE ELECTRIC FEEDS WILL BE FROM THE EXISTING PANELS AND SWITCHGEAR IN THE EXISTING BOILER PLANT. THE BUILDING AUTOMATION SYSTEM (BAS) AND OTHER COMMUNICATIONS WILL BE EXTENDED FROM THE EXISTING BOILER PLANT TO THE TEMPORARY BOILER CONTROL ROOM. ALL FUNCTIONS OF THE CURRENT CONTROL ROOM AND HOSPITAL CRITICAL MONITORING SYSTEMS (MEDICAL GASES, EMERGENCY GENERATOR STATUS, TANKS.) NEED TO BE REPLICATED TO THE TEMPORARY CONTROL ROOM.

THE NATURAL GAS MAIN LINE WILL REQUIRE MODIFICATION PRIOR TO PHASE 2 WORK. A TEE WILL HAVE TO BE INSTALLED IN THE MAIN LINE AND THE EXISTING MANUAL SHUT OFF VALVE WILL REQUIRE RELOCATION TO INSIDE THE BOILER PLANT. THE EXISTING PLANT WILL REQUIRE A SWITCH OVER TO DIESEL FUEL OIL WHILE THE NATURAL GAS LINE IS MODIFIED.

THE CONDENSATE SYSTEM WILL BE MODIFIED SO THE FACILITY CONDENSATE CAN BE TRANSFERRED TO THE TEMPORARY BOILERS. THE NEW CONDENSATE TANK WILL BE LOCATED AT THE EXISTING FUEL OIL #6 PUMPING AREA WITHIN THE BOILER PLANT. THE PIPING FROM THE NEW CONDENSATE TANK WILL BE PIPED TO THE TEMPORARY BOILERS WITH SEVERAL BRANCHES (VALVED AND CAPPED) FOR FUTURE CONNECTIONS TO BOILER FEED SYSTEM IN PHASE 2. EXISTING CONDENSATE TANK AND PUMPS WILL BE DEMOLISHED AFTER NEW CONDENSATE TANK, PUMPS AND PIPING ARE INSTALLED AND

COMMISSIONED.

THE FOLLOWING PIPE MODIFICATIONS WILL NEED TO BE MADE PRIOR TO PHASE 2 INCLUDING STEAM CONNECTION IN THE CHILLER ROOM TO TEMPORARY BOILER, MODIFYING THE CONNECTION TO HOSPITAL STEAM BRANCH, MODIFYING THE CONNECTION TO LAUNDRY STEAM BRANCH, AND MODIFYING THE 4” CONNECTION TO DA TANK PRV. SIMILARLY, CONNECTIONS TO CONDENSATE RETURN LINES FROM HOSPITAL, MEDIUM PRESSURE DRIPS WILL REQUIRE MODIFICATION. THE STEAM PIPING CONNECTIONS FROM THE TEMPORARY BOILERS TO THE HOSPITAL AND LAUNDRY BRANCHES WILL HAVE A TEE WITH SHUTOFF VALVES SO ONCE THE TEMPORARY BOILERS ARE OPERATING, THE EXISTING BOILERS CAN BE ISOLATED.

ONCE ALL THE UTILITIES HAVE BEEN TIED IN, THE TEMPORARY BOILERS WILL BE COMMISSIONED. THE TEMPORARY BOILERS MUST OPERATE FOR TWO WEEKS AFTER COMMISSIONING TO ENSURE THE

BOILERS ARE OPERATING WITHOUT ISSUES BEFORE THE EXISTING BOILERS ARE DEMOLISHED.

EXISTING DOMESTIC WATER HEATERS WILL BE REPLACED WITH NEW IN THIS PHASE. PROVIDE NEW PRV AND CONNECT TO 6” HPS SECONDARY HEADER TO PROVIDE LOW PRESSURE STEAM FOR NEW

DWHS.

EXISTING AHU VFD WILL BE RELOCATED. ALSO EXISTING AIR COMPRESSORS WILL BE PROVIDED WITH THE DDC MONITORING AT THE TEMPORARY CONTROL ROOM.

REPLACE EXISTING HIGH PRESSURE STEAM UNIT HEATER WITH LOW PRESSURE. REPLACE PRV SERVING MUA-1 WITH HIGHER CAPACITY TO PROVIDE LOW PRESSURE STEAM FOR EXISTING MUA-1 AND NEW

UNIT HEATERS.

CROSS-CONNECT EXISTING SUMMER BOILER FUEL PIPING AND WINTER BOILER FUEL PIPING TO ALLOW SUMMER BOILER PUMP TO SERVE EXISTING AND TEMPORARY BOILERS DURING REPLACEMENT OF

WINTER BOILER PUMPS.

LASTLY, PROTECTIVE PARTITIONS, A DUST BARRIER ENCLOSURE WILL BE INSTALLED TO PROTECT EXISTING EQUIPMENT IN THE PLANT THAT ARE NOT SLATED FOR DEMOLITION SO THAT BOILER PLANT

PERSONNEL CAN SERVICE THIS EQUIPMENT DURING CONSTRUCTION.

PHASE 3: (NEW WORK)

PHASE 3 CANNOT COMMENCE UNTIL PHASE 2 WORK HAS BEEN COMPLETED AND ACCEPTED BY THE VA. THE GC WILL RECEIVE A NOTICE TO PROCEED TO PHASE 3 ONCE PHASE 2 WORK IS ACCEPTED BY

THE VA.

THIS PHASE INCLUDES THE DEMOLITION OF EXISTING EQUIPMENT NOT DEMOLISHED DURING PHASE 2 AND INCLUDES THE INSTALLATION OF NEW BOILERS, WATER HEATERS, AND RELATED EQUIPMENT. A NEW STANDBY GENERATOR WILL ALSO BE INSTALLED DURING PHASE 3. THE EXISTING CHIMNEY WILL BE REUSED.

THE FOLLOWING EXISTING EQUIPMENT IS TO BE REMOVED FROM THE BOILER PLANT DURING PHASE 3:

1. (3) EXITING 1000 HP WATER TUBE BOILERS WITH ECONOMIZERS

2. (1) 400 HP SUMMER FIRETUBE BOILER
