* TWO CHILLER SYSTEMS SHALL ALWAYS BE OPERATIONAL DURING CONSTRUCTION.

1. ISOLATE AND DECOMMISSION CHILLER FROM ALL HYDRONIC SYSTEMS. EVACUATE

REFRIGERANT. REMOVE ASSOCIATED HYDRONIC PIPING TO THE NEAREST ISOLATION

VALVES.

2. ISOLATE, DECOMMISSION AND DRAIN COOLING TOWER. DEMOLISH COOLING TOWER

AND PERFORM CONCRETE SUMP REPAIR CONCURRENT WITH CHILLER WORK.

DEMOLISH BOLTED PLATE, WHICH COVERS OPENING BETWEEN CT SUMPS AND

PROVIDE A SLUICE GATE OVER THAT OPENING. REFER TO MD111 AND M-111 FOR MORE

INFORMATION. INSTALL COOLING TOWER. REFER TO MD111 AND M-111 FOR MORE

INFORMATION.

3. REMOVE CHILLED WATER PUMP AND ALL ASSOCIATED PIPING CONNECTIONS TO

BRANCH TEE CONNECTION ON EXISTING 18"Ø HEADER. REFER TO MD801. **THIS WILL

REQUIRE A CHILLED WATER PLANT DRAIN AND SHUTDOWN. UTILIZE CHILLED WATER

BRANCH ISOLATION VALVES SHOWN ON THIS SHEET.**

4. CUT IN NEW 12"Ø ISOLATION VALVES (CODED NOTE 6) ON PUMPS SUCTION PIPING NEAR

TEE CONNECTION. THIS VALVE WILL BE USED IN FUTURE PHASING AND PREVENT

ADDITIONAL PLANT SHUTDOWN AND DRAINAGE.

5. DEMOLISH CHILLER. UTILIZE HATCH OPENING.

6. REMOVE CONDENSER WATER PUMP, CENTRIFUGAL SEPARATOR AND ALL ASSOCIATED

PIPING CONNECTIONS TO THE NEAREST ISOLATION VALVES. REFER TO MD801. **THIS

WILL REQUIRE A CONDENSER WATER PLANT DRAIN AND SHUTDOWN. UTILIZE

CONDENSER WATER BRANCH ISOLATION VALVE SHOWN ON THIS SHEET.**

7. REMOVE REHEAT PIPING TO NEAREST VALVE CONNECTION.

8. INSTALL CHILLER RETURN HEADERS SUPPORT STEEL. REFER TO STRUCTURAL PLANS

FOR MORE INFORMATION.

9. INGRESS THROUGH HATCH AND INSTALL CONDENSER WATER PUMP, AND ASSOCIATED

VALVES AND PIPING. INSTALL CENTRIFUGAL SEPARATOR. REFER TO M-801.

10. INGRESS THROUGH HATCH AND INSTALL CHILLER, AND ASSOCIATED VALES AND

PIPING. REFER TO M-801.

11. INGRESS THROUGH HATCH AND INSTALL CHILLED WATER PUMP. REFER TO M-801.

12. INSTALL 18X18X18 TEE CONNECTION INTO EXISTING 18"Ø HEADER. INSTALL CHILLED

WATER RETURN HEADERS WITH VALVED BRANCH CONNECTIONS. REFER TO M-101 AND

M-801.

13. REPLACE REDUCED PRESSURE ZONE VALVE (RPZ-1) ON THE DOMESTIC WATER

MAKEUP WATER LINE. REFER TO M-111 FOR MORE INFORMATION.

14. DEMO AND INSTALL NEW CONDENSER WATER MAKEUP WATER PIPING. REFER TO M-111

FOR MORE INFORMATION.

15. **FILL CHILLED WATER SYSTEM, CONDENSER WATER SYSTEM AND COOLING TOWER

SUMP. CHILLED WATER AND CONDENSER WATER SYSTEM OUTAGE COMPLETE**

16. INSTALL NEW COOLING TOWER.

17. INSTALL WATER SOFTENING SYSTEM. REFER TO M-111 FOR MORE INFORMATION.

18. CONNECT CHILLED WATER PUMP SUCTION AND DISCHARGE TO HEADER PIPING.

19. CONNECT CHILLER TO HEADER PIPING.

20. TEST, COMMISSION AND GOVERNMENT SHALL ACCEPT CHILLER, COOLING TOWER,

CHILLED WATER PUMP, CONDENSER WATER PUMP, AND RELATED COMPONENTS FOR

OPERATION PRIOR TO WORKING ON THE NEXT CHILLER SYSTEM. THIS IS TO ENSURE

CHILLER PERFORMANCE AND MAINTAIN CHILLER PLANT CAPACITY BEFORE

SUBSEQUENT SYSTEMS ARE DEMOLISHED.

· REPEAT STEPS ABOVE WITH RESPECTS TO THE NEXT CHILLER AND COOLING TOWER.

CHILLED WATER AND CONDENSER WATER OUTAGE SHOULD NOT BE NECESSARY. AT

THIS POINT, NEW HEADER PIPING IS INSTALLED. CHILLER INGRESS (DISASSEMBLED)

MUST PASS BELOW PIPING NEW HEADER PIPING. REFER TO M-301.

· WHEN COOLING TOWER'S SUMP IS DRAINED, DEMOLISH TWO BOLTED PLATES WHICH

COVER OPENINGS AT EACH DEMISING SUMP WALL AND PROVIDE A SLUICE GATE OVER

CHILLED WATER AND CONDENSER WATER OUTAGE SHOULD NOT BE NECESSARY.

WHEN COOLING TOWER'S SUMP IS DRAINED, DEMOLISH BOLTED PLATE WHICH COVERS

THE OPENING.

· **IMPORTANT** PRIOR TO REMOVING THE REHEAT PIPING FROM CHILLER, INSTALL

FULL SIZE BRIDGE PIPING ON THE REHEAT RETURN PIPING AS DESCRIBED ON THE

MD101 AND M-101. FAILURE TO BRIDGE THE REHEAT RETURN PIPING WILL DEADHEAD

THE BUILDING REHEAT PUMPS. THIS WILL REQUIRE A BUILDING HEAT PLANT ISOLATION

AND SHUT DOWN TO REMOVE AND INSTALL BRIDGE PIPING. COORDINATE THIS WORK

DURING ANNUAL STEAM PLANT SHUTDOWN, TYPICALLY IN JUNE.

FEEDS BETWEEN THE MCC'S, ISOLATION TRANSFORMERS, VFD'S, SWITCHES AND

PUMPS.

2. TRIP SWITCHGEAR BRANCH BREAKER FOR CHILLER 2 AND 3. OPEN MCC BREAKERS

FOR PUMPS P-2 AND P-5

3. PROVIDE NEW CHILLER 2 SOFT STARTER AND CAP BANK. PROVIDE WIRING BETWEEN

PR-1, THE STARTER, CAP BANK, AND THE NEW CHILLER.

4. REMOVE TEMPORARY STARTERS AND PROVIDE FUSED DISCONNECT SWITCHES FOR

1. THE CONTRACTOR SHALL CONDUCT ALL OPERATIONS IN STRICT ACCORDANCE WITH

THE SAFETY REQUIREMENTS IMPOSED BY THE CONTRACTING OFFICER AND EM 385-1-1.

IT IS SOLELY THE CONTRACTOR'S RESPONSIBILITY TO FOLLOW ALL APPLICABLE

SAFETY CODES AND REGULATIONS GOVERNING THIS WORK. THE CONTRACTOR SHALL

REMOVE ALL DEBRIS FROM THE OWNER'S PROPERTY AND DISCARD ACCORDING TO

LOCAL REGULATIONS.

2. THIS STRUCTURE IS DESIGNED TO BE SELF-SUPPORTING AND STABLE AFTER IT IS

FULLY COMPLETED. HOWEVER, THE CONTRACTOR IS RESPONSIBLE TO DETERMINE

THE ERECTION PROCEDURES AND SEQUENCES REQUIRED TO ENSURE STABILITY

OF THE STRUCTURE AND ITS COMPONENT PARTS DURING CONSTRUCTION.

ANY TEMPORARY BRACING, CONNECTIONS, GUYS, OR TIE-DOWNS THAT MAY BE

NECESSARY DURING ERECTION ARE NOT SHOWN ON STRUCTURAL DRAWINGS. IF

APPLIED THEY SHALL BE REMOVED AS CONDITIONS PERMIT, AND SHALL REMAIN

THE PROPERTY OF THE CONTRACTOR. THIS CONSTRUCTION STABILITY REQUIREMENT

APPLIES CONTINUOUSLY AND IS NOT LIMITED TO NORMAL WORKING HOURS.

3. THE PROJECT SPECIFICATIONS SHALL BE USED IN CONJUNCTION WITH THE STRUCTURAL

DRAWINGS TO DETERMINE THE COMPLETE PROJECT REQUIREMENTS. ANY DISCREPANCIES

OR CONFLICTS FOUND BETWEEN THE PROJECT SPECIFICATIONS AND THE STRUCTURAL

DRAWINGS SHALL BE BROUGHT TO THE ATTENTION OF THE COR IMMEDIATELY. THE

STRICTEST PROVISION SHALL GOVERN UNLESS THE COR DETERMINES OTHERWISE

5. DIMENSIONS PERTAINING TO EXISTING CONDITIONS SHALL BE FIELD VERIFIED BY THE

CONTRACTORS PRIOR TO SHOP DRAWING SUBMISSION, ANY FABRICATION, CONSTRUCTION,

OR ERECTION

7. EXISTING UTILITIES AND ALL OTHER OBSTRUCTIONS TO WORK SHALL BE TEMPORARILY

REMOVED AND RE-INSTALLED (INCLUDING NECESSARY MODIFICATIONS) BY THE CONTRACTOR

AFTER COMPLETION OF NEW WORK.

8. OPENING SIZES AND LOCATIONS SHOWN FOR PIPES, DUCTS, ETC. ARE SHOWN FOR GENERAL INFORMATION ONLY. REFER TO RELATED DRAWINGS (ARCH., MECH., ELECT, ETC.) FOR OTHER

POSSIBLE EQUIPMENT SUPPORTS; WALL, FLOOR AND ROOF OPENINGS, SLEEVES, AND OTHER

EMBEDDED ITEMS NOT SPECIFICALLY INDICATED ON STRUCTURAL DRAWINGS. COORDINATE

ALL REQUIRED DIMENSIONS WITH APPLICABLE TRADE CONTRACTORS PRIOR TO ANY STEEL

FABRICATION OR CONCRETE PLACEMENT.

9. ALL FRAMING MEMBERS PROVIDED FOR MECHANICAL TRADES, LINTELS, ROOF OPENINGS, ETC.

ARE FOR BIDDING PURPOSES ONLY. THE CONTRACTOR SHALL SUBMIT MANUFACTURER'S

DESIGN DATA FOR THE PROPOSED EQUIPMENT PRIOR TO STEEL SHOP DRAWING SUBMITTAL,

TO ACCOMMODATE THE ACTUAL CONDITION.

GENERAL NOTES

4. SHOP DRAWINGS REQUIRED BY THE PROJECT SPECIFICATIONS AND PREPARED BY

SUPPLIERS AND/OR SUBCONTRACTORS SHALL BE REVIEWED AND STAMPED BY THE

CONTRACTOR PRIOR TO SUBMISSION TO THE GOVERNMENT. ALL DEVIATIONS

DRAWINGS BY THE CONTRACTOR. NO SHOP WORK IS PERMITTED TO COMMENCE UNTIL

THE RETURN OF A STAMPED, APPROVED COPY OF THE SHOP DRAWINGS TO THE

CONTRACTOR.

6. ALL DETAILS, SECTIONS, AND NOTES PROVIDED ON STRUCTURAL DRAWINGS ARE INTENDED

TO BE TYPICAL FOR SIMILAR SITUATIONS ELSEWHERE, UNLESS SPECIFICALLY NOTED

OTHERWISE. FOR ANY DETAILS AND DIMENSIONS NOT PROVIDED, REFER TO ARCHITECTURAL,

MECHANICAL, ANY EXISTING DRAWINGS, AND BY FIELD OBSERVATION. ALL DIMENSIONS AND

ELEVATIONS SHOWN ON STRUCTURAL DRAWINGS WERE INTENDED TO CONFORM WITH THE

INFORMATION PROVIDED ON ARCHITECTURAL DRAWINGS. THE CONTRACTOR SHALL REPORT

ANY DISCREPANCIES TO THE COR FOR RESOLUTION BEFORE PROCEEDING WITH ANY

ADDITIONAL WORK.
