A. THE ELECTRICAL CONTRACTOR SHALL OBTAIN ALL NECESSARY PERMITS

FROM AUTHORITY HAVING JURISDICTION AND PAY ALL ASSOCIATED FEES.

B. LOCATE JUNCTION AND PULL BOXES AS REQUIRED TO ALLOW ACCESS

AFTER EQUIPMENT AND APPURTENANCES ARE INSTALLED. COORDINATE

LOCATIONS AND ELEVATIONS OF ELECTRICAL DEVICES WITH DRAWINGS

AND OTHER TRADES PRIOR TO INSTALLATION.

C. PROTECT PERMANENT BUILDING FIXTURES FROM DAMAGE DURING

CONSTRUCTION PERIOD. PROVIDE PLYWOOD OR SIMILAR MATERIAL

UNDER EQUIPMENT OR MATERIALS STORED ON FLOORS AND IN AREAS

WHERE CONSTRUCTION MAY DAMAGE FINISHES. SURFACES OR FINISHES

DAMAGED DURING CONSTRUCTION SHALL BE REPLACED AT THE COST OF

THE CONTRACTOR.

D. BRANCH CIRCUITS OVER 75 FEET (25 METERS) IN LENGTH (TOTAL ONE

WAY) FROM THE PANEL, THE ELECTRICAL CONTRACTOR SHALL

CALCULATE THE VOLTAGE DROP AND PROVIDE AN APPROPRIATE

CONDUCTOR SIZE TO ACHIEVE NO MORE THAN 3% MAXIMUM ALLOWABLE

VOLTAGE DROP.

E. DO NOT SCALE THE DRAWINGS. BECAUSE OF THE SCALE OF THE

DRAWINGS, IT IS NOT POSSIBLE TO INDICATE ALL OFFSETS, FITTINGS OR

OTHER SIMILAR ITEMS WHICH MAY BE REQUIRED TO MAKE A COMPLETE

OPERATING SYSTEM. CAREFULLY INVESTIGATE CONDITION AFFECTING

WORK AND INSTALL WORK IN SUCH A MANNER THAT INTERFERENCES

BETWEEN PIPES, CONDUIT, DUCT, EQUIPMENT, ARCHITECTURAL AND

STRUCTURAL FEATURES SHALL BE AVOIDED.

F. PROVIDE 'SEAL-OFFS' WHEN CONDUIT PASSES THROUGH AREAS OF

DIFFERENT AMBIENT TEMPERATURES AND/OR HAZARDOUS AREAS.

G. IF MORE THAN THREE CURRENT-CARRYING CONDUCTORS ARE ROUTED

IN THE SAME CONDUIT, DERATING SHALL BE TAKEN INTO ACCOUNT.

INCREASING THE CONDUCTOR AMPACITY (BY INCREASING WIRE SIZE) TO

COMPENSATE AS FOLLOWS:

NO. OF CONDUCTORS AMPACITY INCREASE

4 THRU 6 125%

7 THRU 9 145%

10 THRU 20 (MAX) 200%

THE CONDUIT SIZE (CAPACITY) SHALL ALSO BE INCREASED TO CONFORM

TO NEC, CHAPTER 9.

H. ALL EQUIPMENT TO BE CONSIDERED 'AS-EQUAL' MUST BE SUBMITTED TO

THE ENGINEER FOR APPROVAL NO LATER THAN ONE (1) WEEK PRIOR TO

BID DATE.

I. IT IS THE CONTRACTORS RESPONSIBILITY TO COORDINATE WITH ALL

TRADES FOR SUBSTITUTED EQUIPMENT FROM THIS DESIGN.

UNCOORDINATED CHANGES THAT OCCUR FROM A SUBSTITUTION WILL BE

THE CONTRACTORS RESPONSIBILITY TO ABSORB THE COST AND NOT

PASS ONTO THE OWNER.

J. PROVIDE PROTECTION IN FIRE RATED WALL MEMBRANE PENETRATIONS.

PROTECTION SHALL WRAP THE OUTSIDE OF THE BOX OR ENCLOSURE TO

MAINTAIN WALL FIRE RATING. DO NOT USE PENETRATION PROTECTION

ON THE INTERIOR OF BOX/ENCLOSURE OR COVER PLATE TYPE

PROTECTION. REFER TO SPECIFICATIONS FOR ADDITIONAL INFORMATION.

K. LISTED OR LABELED EQUIPMENT SHALL BE INSTALLED AND USED IN

ACCORDANCE WITH ANY INSTRUCTION INCLUDED IN THE LISTING

OR LABELING. (NEC 110.3.B).

SCOPE OF WORK

REPLACE EXISTING DIESEL GENERATOR WITH NEW DIESEL GENERATOR, AS

SPECIFIED BELOW. INSTALL POWER, CONTROL, AND FUEL CONNECTIONS.

CONTROL CONNECTIONS SHALL INCLUDE START SIGNALS FROM ALL 3

EXISTING ATS'S. FUEL CONNECTIONS SHALL INCLUDE FUEL PIPING FROM

THE ADJACENT EXISTING FUEL TANK, AND CONTROL WIRING TO NEW

SUB-BASE TANK, COMPLETE WITH FUEL LEVEL FLOAT SWITCH TO SIGNAL

"LOW FUEL". TEST UNDER FULL LOAD WITH A TEMPORARY LOAD BANK.

REMOVE EXISTING GENERATOR AND DISPOSE OF THE EXISTING GENERATOR

AS DIRECTED BY OWNER.

PROVIDE A TEMPORARY GENERATOR, COMPLETE WITH CABLES AND THE

REQUIRED FUEL TO PROVIDE STANDBY BY POWER DURING GENERATOR

REPLACEMENT. GENERATOR SHALL START AND RUN DURING

INTERRUPTIONS OF NORMAL POWER.

1. THE EXISTING GENERATOR SHALL BE REMOVED AND DISPOSED

OF IN ACCORDANCE WITH THE OWNER'S INSTRUCTIONS. REMOVE

THE FOLLOWING ITEMS FROM THE GENERATOR AND INSTALL

THEM ON THE NEW GENERATOR:

a. POWER AND SIGNAL CABLES TO THE ALTERNATOR, CONTROL

PANEL, POWER TO FUEL PUMP, BATTERY CHARGER AND BLOCK

HEATER.

b. FUEL LINES, FUEL PUMP, FLOAT VALVE, AND VENT STACKS

2. ORIENT NEW GENERATOR ON THE EXISTING GENERATOR PAD AS

SHOWN.

3. LOCATION OF EXISTING GENERATOR DOCKING STATION TO

REMAIN. MAKE POWER AND SIGNAL CONNECTIONS HERE.

4. DEVIATION FROM THE BASIS OF DESIGN WILL REQUIRE THE

CONTRACTOR TO ENLARGE THE GENERATOR PAD TO

ACCOMMODATE THE NEW GENERATOR, AT NO ADDITIONAL COST

TO THE OWNER.

5. CONNECT EXISTING GENERATOR FEEDERS, RETAINED FOR

GENERATOR REMOVAL, TO NEW GENERATOR. REFER TO ONE-

LINE DIAGRAM E0.1.

6. CONNECT EXISTING FUEL TANK FUEL LINES, RETAINED FOR

GENERATOR REMOVAL, TO NEW GENERATOR. REFER TO ONE-

LINE DIAGRAM E0.1.

GENERAL NOTES

A. REFER TO DRAWING E0.0 FOR ELECTRICAL LEGEND,

ABBREVIATIONS AND GENERAL NOTES - ELECTRICAL

B. ELECTRICAL CONTRACTOR SHALL VERIFY WITH

CONSTRUCTION MANAGER, THAT A SURVEY HAS BEEN

CONDUCTED AND ALL UNDERGROUND UTILITIES HAVE BEEN

IDENTIFIED.

C. UTILITIES SHOWN ON THESE DRAWINGS ARE FOR

REFERENCE ONLY. ELECTRICAL CONTRACTOR SHALL

COORDINATE EXACT LOCATION OF ALL EXISTING UTILITIES

AND ROUTING OF ALL NEW UNDERGROUND UTILITIES WITH

RESPECTIVE TRADES (PLUMBING, CIVIL, ETC.), PRIOR TO

DIGGING. MINIMIZE DIGGING BY SHARING TRENCHES

WHENEVER POSSIBLE.

D. COORDINATE SERVICE SHUT-DOWNS WITH ALL TRADES

INVOLVED ON SITE AND OBTAIN WRITTEN AUTHORIZATION

FROM OWNER 72 HOURS PRIOR TO ANY ELECTRICAL WORK.
