RECEPTACLE BRANCH CIRCUITS WITH A TOTAL LENGTH LONGER THAN 150' SHALL UTILIZE #8 AWG

CONDUCTORS.

B. FOR ALL CONDUIT AND OTHER ITEMS PENETRATING A FIRE RATED WALL, PROVIDE UL LISTED THROUGH PENETRATION FIRE STOPPING SYSTEM THAT IS SPECIFIC TO THE WALL CONSTRUCTION ASSEMBLY AND COMPLIANT WITH ASTM E814. INSTALL SYSTEM IN STRICT COMPLIANCE WITH THE FIRE STOPPING MANUFACTURER’S U.L. APPROVED DETAIL. WHERE EXISTING WALLS ARE BEING UPGRADED TO FIRE RATED WALLS OR THE FIRE RATING IS BEING MODIFIED, PROVIDE U.L. LISTED THROUGH PENETRATION FIRE STOPPING SYSTEM FOR ALL NEW AND EXISTING PENETRATIONS. REFER TO THE ARCHITECTURAL LIFE

SAFETY PLANS FOR LOCATIONS OF FIRE RATED WALLS.

C. NEW ROOF MOUNTED EQUIPMENT SHALL BE BONDED TO EXISTING BUILDING LIGHTNING PROTECTION SYSTEM IF ONE EXISTS. PROVIDE AIR TERMINALS ON TOP OF EQUIPMENT AND BOND TO EXISTING SYSTEM PER NFPA 780 AND UL 96A REQUIREMENTS. PROVIDE UL INSPECTION AND/OR LPI SYSTEM INSPECTION AS REQUIRED TO OBTAIN UL MASTER LABEL RECERTIFICATION, UL MASTER LABEL AND/OR LPI SYSTEM

CERTIFICATE.

D. ANY ITEMS DAMAGED BY THE CONTRACTOR SHALL BE REPLACED BY THE CONTRACTOR, AT NO ADDITIONAL

COST TO THE OWNER.

E. NEW WIRING DEVICES AND ASSOCIATED COVERPLATES SHALL MATCH EXISTING FINISH OF SIMILAR

INSTALLED DEVICES.

F. THE SELECTED EQUIPMENT AIC RATINGS ARE BASED ON THE IMPEDANCES FOR CONDUCTORS AND TRANSFORMERS USED IN THE CALCULATIONS. IF DIFFERENT EQUIPMENT OR DIFFERENT CONFIGURATIONS

ARE SELECTED FOR INSTALLATION, THE CONTRACTOR SHALL BE RESPONSIBLE FOR PROVIDING

ADEQUATELY RATED EQUIPMENT THAT MEETS APPLICABLE SELECTIVE COORDINATION GOALS AND

PROVIDES SIMILAR INCIDENT ENERGY RISK OF ARC FLASH HAZARDS.

G. ALL CRITICAL AND LIFE SAFETY BRANCH CIRCUITS, INCLUDING LIGHTING AND WALL RECEPTACLES, SHALL BE MECHANICALLY PROTECTED PER NEC 517.31(C)(3). NON-FLEXIBLE RACEWAY SHALL BE USED FOR CRITICAL AND LIFE SAFETY BRANCH CIRCUITS, EXCEPT THAT THE FINAL CONNECTION TO VIBRATING EQUIPMENT OR LIGHT FIXTURES IF THE TOTAL LENGTH OF FLEXIBLE RACEWAY IS 6' OR LESS ACROSS THE

ENTIRE CIRCUIT LENGTH.

H. PROVIDE ADDITIONAL SUPPORTS AS REQUIRED TO INDEPENDENTLY SUPPORT ALL EXISTING TO REMAIN

CABLING.

I. FOR TEMPORARY FEEDERS, CONTRACTOR HAS CHOICE OF DIRECT BURIED CABLING OR CONDUIT AND RAN ACROSS FENCED OFF AREA. REFER TO SPECS FOR CABLE TYPES. TEMPORARY CONNECTIONS ARE NOT

SHOWN ON THE DRAWINGS. COORDINATE LOCATION OF TEMPORARY TRANSFORMERS, TEMPORARY

CABLING, AND TEMPORARY FENCING WITH THE VA. ALTERNATE TEMPORARY LOCATIONS OF EQUIPMENT TO ACCOMMODATE CONTINUITY OF SERVICES AT THE VA AS REQUIRED BY THE VA STAFF SHALL NOT BE

GROUNDS FOR ADDITIONAL COMPENSATION.

REPLACE TRANSFORMERS THROUGHOUT CAMPUS. REUTILIZE EXISTING TRANSFORMERS REMOVED FOR

TEMPORARY POWER FOR OTHER TRANSFORMERS WITH LONGER DURATION OUTAGES.

A. COORDINATE OUTAGE DATE, TIMING, AND DURATION WITH VA PRIOR TO SHUTDOWNS. OUTAGE DURATION

TOLERANCES VARY BY BUILDING SERVED. SPECIAL CONSIDERATION IS REQUIRED FOR BUILDING 137 OUTAGE IN COORDINATION WITH NAVFAC. REFER TO BUILDING 137 PHASING NOTES FOR FURTHER DETAILS.

B. RETAIN EXISTING TRANSFORMER FOR TEMPORARY POWER USE FOR OTHER BUILDINGS CONSTRUCTION

PHASING PRIOR TO DISPOSAL.

a. REMOVE 150KVA, 4160∆ /208Y EXTERIOR TRANSFORMER FROM BUILDING 11 TO UTILIZED FOR OTHER

BUILDINGS WITH 150KVA TRANSFORMERS.

b. REMOVE 750KVA, 4160∆ /208Y EXTERIOR TRANSFORMER FROM BUILDING 1 TO UTILIZED FOR OTHER

BUILDINGS WITH 300KVA TRANSFORMERS.

c. RETAIN OTHER 150KVA TRANSFORMERS FOR USE IF DESIRED TO DO MULTIPLE TRANSFORMER

REPLACEMENTS SIMULTANEOUSLY.

C. SEQUENCE OF TRANSFORMER REPLACEMENT (SEQUENCE REQUIRED FOR EXISTING TRANSFORMERS THAT

WILL BE REMOVED TO BE UTILIZED FOR TEMPORARY FEED TO ANOTHER BUILDING SERVICE):

a. BUILDING 1 AND 3.

b. BUILDING 187.

c. ALL OTHER BUILDINGS REQUIRING TEMPORARY TRANSFORMER FEEDS.

SHEET NOTES:

1. REPLACE EXISTING TRANSFORMER IN-PLACE. DISCONNECT EXISTING PRIMARY AND SECONDARY FEEDERS

AND RECONNECT TO NEW.

2. REPLACE EXISTING SWITCHBOARD MDP 137 IN-PLACE. DISCONNECT EXISTING LINE AND LOAD FEEDERS AND

RECONNECT TO NEW.

3. CONTRACTOR TO LOCATE AND MARK EXISTING UNDERGROUND UTILITIES AROUND LOCATION OF BOLLARDS TO BE ADDED. IF UTILITY LINES INTERFERE WITH BOLLARD LOCATION, COORDINATE MODIFIED LOCATION WITH COR AND ENSURE NO GREATER THAN 6' GAP IN BETWEEN BOLLARDS ON THE FRONT SIDE OR 5' ON THE

SIDES WHILE MAINTAINING WORKING CLEARANCE AROUND THE FENCE.

REPLACE EXISTING TRANSFORMER AND SWITCHBOARD IN-PLACE. COORDINATE OUTAGE DATE, TIMING, AND DURATION WITH BOTH THE VA AND NAVFAC UTILITIES PRIOR TO SHUTDOWNS. OUTAGES TO BE EVENINGS AND WEEKENDS. BUILDING 137 PROVIDES PUMPING TO BOTH THE VA CAMPUS WATER DISTRIBUTION AND NAVAL CAMPUS WATER DISTRIBUTION AND ELECTRICAL SERVICE TO BUILDINGS 137 (PUMP HOUSE), 138 (WAREHOUSE), AND BUILDING 139 (GARAGE AND 4160V SWITCHGEAR). OUTAGES SHALL BE KEPT TO A MINIMUM. OUTAGES SHALL BE COORDINATED WITH THE VA AND NAVFAC AT LEAST TEN (10) BUSINESS DAYS PRIOR TO PLANNED OUTAGE.

• BUILDING 137 CAN SUSTAIN A MULTIDAY POWER OUTAGE TO FACILITATE REPLACING THE SWITCHGEAR

THAT FEEDS B137, B138 AND B139.

• THE WAREHOUSE (B138) SHALL BE RESTRICTED TO A WEEKEND OUTAGE.

A. OVER A WEEKEND, REMOVE EXISTING 'MDP 137' AND REPLACE IN-PLACE.

B. DE-ENERGIZE THE EXISTING EQUIPMENT.

C. DISCONNECT EXISTING FEEDERS TO BUILDINGS 137, 138, 139, AND PUMPS WITHIN 137.

D. REMOVE EXISTING 'MDP 137'.

E. INSTALL NEW 'MDP 137'.

F. RECONNECT EXISTING FEEDERS TO BUILDINGS 137, 138, 139, AND PUMPS WITHIN 137.

G. AFTER COMPLETION OF MDP REPLACEMENT, REPLACE TRANSFORMER IN-PLACE A FUTURE WEEKEND.

H. DE-ENERGIZE THE EXISTING TRANSFORMER.

I. DISCONNECT EXISTING PRIMARY AND SECONDARY CONDUCTORS.

J. PROTECT EXISTING CONCRETE PAD, CONDUITS, AND CONDUCTORS.

K. REMOVE EXISTING TRANSFORMER.

L. INSTALL NEW TRANSFORMER.

M. RE-TERMINATE EXISTING CONDUCTORS ONTO THE NEW TRANSFORMER.
