GENERAL NOTES:

1. ALL VFD'S WILL BE FURNISHED BY THE MECHANICAL CONTRACTOR. THE ELECTRICAL CONTRACTOR SHALL MOUNT THE

VFD'S (UNLESS THEY ARE INTEGRAL TO THE EQUIPMENT SERVED). CONNECT THE LINE SIDE POWER WIRING AND THE

LOAD SIDE POWER WIRING FROM THE VFD'S TO THE EQUIPMENT. ALL CONTROL AND INTERLOCK WIRING FOR THE VFD'S

WILL BE BY THE CONTROL SYSTEM CONTRACTOR.

2. LOAD SIDE CONDUCTOR AND CONDUIT SIZES FROM DISCONNECT SWITCHES, STARTERS AND VFD'S TO EQUIPMENT SHALL

BE THE SAME AS LINE SIDE CONDUCTORS AND CONDUIT.

3. CAREFULLY COORDINATE ALL ELECTRICAL EQUIPMENT LOCATIONS WITH DUCTWORK, PIPING AND MECHANICAL

EQUIPMENT. MAINTAIN ALL CLEARANCES AND SPACES REQUIRED BY THE NEC.

4. WHERE MULTIPLE CIRCUITS ARE COMBINED IN A SINGLE CONDUIT, DERATE CONDUCTORS PER THE NEC.

5. WHERE RE-USE OF EXISTING CONDUIT, WIRING AND/OR OUTLET BOXES IS INDICATED, ALSO PROVIDE NEW MATERIALS IF

NECESSARY. IF NEW EXPOSED MATERIALS ARE NEEDED, USE SURFACE RACEWAY (SINGLE-CHANNEL EXCEPT WHERE

SPECIFICALLY INDICATED OTHERWISE), EXCEPT EXPOSED CONDUIT AND BOXES MAY BE USED IN UNFINISHED AREAS

(MECHANICAL/ELECTRICAL/IT ROOMS, STORAGE AND HOUSEKEEPING CLOSETS, ETC.).

6. PROVIDE ALL 120-VOLT POWER NEEDED BY THE BAS. COORDINATE WITH THE CONTROLS SPECIFICATIONS AND

CONTRACTOR.

7. MODIFY EXISTING PANEL SCHEDULES TO ACCURATELY REFLECT ALL CHANGES MADE AS PART OF THIS CONTRACT. ALL

NEW BREAKERS IN EXISTING PANELS SHALL MATCH EXISTING AIC. PROVIDE NEW "TYPED" AS-BUILT PANEL SCHEDULES, HANDWRITTEN PANEL SCHEDULES WILL NOT BE ACCEPTED.

8. THE CONTRACTOR SHALL VISIT THE SITE PRIOR TO SUBMITTING BID IN ORDER TO VERIFY ALL EXISTING CONDITIONS, TO

DETERMINE THE FULL EXTENT OF DEMOLITION WORK REQUIRED, AND TO DETERMINE THE FULL EXTENT OF RELOCATION

AND MODIFICATION WORK REQUIRED FOR ELECTRICAL WORK (DUE TO OTHER DISCIPLINES INTERFERING OR ANY OTHER

REASON). EXISTING SPACE IS TIGHT IN MANY AREAS (PARTICULARLY ABOVE CEILINGS), AND THE CONTRACTOR SHALL BE

FULLY RESPONSIBLE TO COORDINATE ALL ELECTRICAL WORK WITH BOTH NEW AND EXISTING PIPING, DUCTWORK, CONDUIT, ETC. NO CHANGE ORDERS WILL BE APPROVED FOR ADDITIONAL WORK DUE TO THE CONTRACTOR NEGLECTING

TO VISIT THE SITE AND GATHER ALL NECESSARY INFORMATION.

9. THE CONTRACTOR SHALL PROVIDE COVERPLATES ON ALL EXISTING JUNCTION BOXES ABOVE THE ACCESSIBLE CEILING

SPACES AND ANY WALL MOUNTED BOXES IN THE AREA OF RENOVATIONS WHERE EXISTING COVERPLATES ARE MISSING.

THE CONTRACTOR SHALL ALSO PROVIDE ADDITIONAL SUPPORTS FOR EXISTING CONDUIT AND JUNCTION BOXES IN THE

AREA OF RENOVATIONS THAT CURRENTLY DO NOT MEET CODE REQUIREMENTS.

10. WHERE EXISTING CIRCUITS ARE SPECIFIED TO BE REUSED FOR THE AREA OF RENOVATIONS AND THE CONTRACTOR

DISCOVERS IN THE FIELD THAT THE CIRCUITS DO NOT MEET CODE, OR THEY HAVE SHARED NEUTRALS, OR THEY ARE

MISSING A GROUND CONDUCTOR THE CONTRACTOR SHALL PROVIDE NEW CONDUIT AND WIRING FROM THE PANEL TO

THE EXISTING AND NEW ELECTRICAL EQUIPMENT. ALL NEW CIRCUITS SHALL MEET SPECIFICATIONS FOR VOLTAGE DROP

FOR SINGLE-PHASE WIRING.

GENERAL DEMOLITION NOTES:

1. SCOPE : THE SCOPE OF ELECTRICAL DEMOLITION IS DEFINED IN THE FOLLOWING NOTES AND IN LIMITED FASHION ON THE

DRAWINGS; THE DRAWINGS ARE ONLY INTENDED TO BE A PARTIAL REPRESENTATION OF THE ACTUAL DEMOLITION WORK

REQUIRED. THESE NOTES ONLY APPLY TO THE AREAS OF RENOVATION. IN GENERAL, THE DEMOLITION SCOPE IS THE

REMOVAL OF THE ELECTRICAL CONNECTIONS TO THE EXISTING CHILLER AND THE EXISTING CHILLED WATER PUMPS, EXCEPT AS NOTED OTHERWISE IN THESE NOTES AND ON THE DRAWINGS.

2. MECHANICAL EQUIPMENT : DISCONNECT EXISTING MECHANICAL EQUIPMENT THAT IS BEING REMOVED, AND REMOVE ALL

ASSOCIATED STARTERS, DISCONNECTS, ETC. CONDUIT AND CONDUCTORS TO REMOVED MECHANICAL EQUIPMENT SHALL BE

REUSED ONLY WHERE SPECIFICALLY INDICATED. SEE MECHANICAL DRAWINGS FOR MORE INFORMATION. UNLESS

SPECIFICALLY INDICATED OTHERWISE, EXISTING WIRING TO EXISTING-TO-REMAIN EQUIPMENT SHALL REMAIN.

3. ELECTRICAL SERVICE : THE EXISTING ELECTRICAL SERVICE SHALL BE RE-USED, BUT SOME DOWNTIME WILL LIKELY STILL BE

REQUIRED. ALL ELECTRICAL SERVICE DOWNTIME REQUIRED SHALL BE COORDINATED WITH OWNER AND SHALL BE AT THE

OWNER'S CONVENIENCE. DOWNTIME SHALL BE KEPT TO THE MINIMUM. ALL EXTENDED DOWNTIME REQUIRED SHALL BE

COORDINATED WITH OWNER AND SHALL BE OUTSIDE OF NORMAL SCHOOL HOURS.

4. PANELBOARDS : ALL EXISTING PANELBOARDS ARE TO REMAIN. EXISTING PANELBOARDS ARE TO BE MODIFIED AS INDICATED

ON FLOOR PLANS AND PANEL SCHEDULES. WHERE EXISTING PANELBOARDS ARE TO REMAIN UPDATE THE CIRCUIT

DIRECTORIES TO REFLECT ALL AS-BUILT/EXISTING CIRCUIT CHANGES, ALL REVISED CIRCUIT DIRECTORIES SHALL BE "TYPED"

NOT HANDWRITTEN. CIRCUIT CHANGES INCLUDE, BUT IS NOT LIMITED TO, MOVING EXITING LOADS IN EXISTING PANELS, REMOVING EXISTING LOADS FROM AN EXISTING PANELS, ADDING NEW LOADS TO EXISTING PANELS, CHANGING BREAKERS IN

EXISTING PANELS, ETC. EXISTING CIRCUITS NO LONGER BEING USED AFTER DEMOLITION WORK SHALL BE MADE "SPARES"

AND SHALL BE PLACED IN THE "OFF" POSITION. PROVIDE BLANK PLATES FOR ALL EXISTING CIRCUIT BREAKERS BEING

REMOVED.

5. CONDUIT : ALL ACCESSIBLE UNUSED CONDUIT SHALL BE REMOVED; ALL INACCESSIBLE UNUSED CONDUIT SHALL BE

ABANDONED. ALL CONDUIT TO NEW DEVICES AND EQUIPMENT SHALL BE NEW, UNLESS NOTED OTHERWISE TO BE REUSED.

6. WIRING : ALL WIRING TO DEMOLISHED DEVICES AND EQUIPMENT SHALL BE REMOVED, UNLESS NOTED OTHERWISE. ALL

EXISTING WIRING TO EXISTING-TO-REMAIN DEVICES AND EQUIPMENT SHALL REMAIN, UNLESS NOTED OTHERWISE. ALL

ACCESSIBLE UNUSED WIRING SHALL BE REMOVED; ALL INACCESSIBLE UNUSED WIRING SHALL BE ABANDONED. ALL WIRING

TO NEW DEVICES AND EQUIPMENT SHALL BE NEW, UNLESS NOTED OTHERWISE.

7. MAINTAIN CIRCUIT CONTINUITY AS NECESSARY IN ALL DEMOLITION WORK.

8. THE CONTRACTOR SHALL INFORM THE OWNER'S REPRESENTATIVE OF ELECTRICAL EQUIPMENT REMOVED FROM THE

BUILDING. IF THE OWNER DESIRES TO RETAIN EQUIPMENT, HE WILL REMOVE IT FROM THE SITE. ALL EQUIPMENT NOT

RETAINED BY THE OWNER SHALL BECOME PROPERTY OF THE CONTRACTOR AND SHALL BE REMOVED FROM THE SITE.

DISPOSAL OF ALL EQUIPMENT CONTAINING HAZARDOUS MATERIALS SHALL BE THE RESPONSIBILITY OF THE CONTRACTOR, AND THE COST OF DISPOSAL SHALL BE INCLUDED.

9. INFORMATION ON DEMOLITION DRAWINGS DOES NOT INDICATE ALL EXISTING EQUIPMENT AND DEVICES. REFER TO

ARCHITECTURAL AND MECHANICAL DEMOLITION DRAWINGS FOR ADDITIONAL INFORMATION.

10. THE CONTRACTOR SHALL VISIT THE SITE PRIOR TO SUBMITTING BID AND SHALL VERIFY ALL DEMOLITION REQUIRED.

ADDITIONAL COMPENSATION WILL NOT BE ALLOWED FOR DEMOLITION DUE TO CONTRACTOR NOT VISITING SITE AND

DETERMINING FULL SCOPE OF DEMOLITION REQUIRED.

11. SEE THE DEMOLITION FLOOR PLANS FOR ADDITIONAL DEMOLITION REQUIREMENTS. ON THE DEMOLITION FLOOR PLANS AND

RISERS, ALL DASHED ITEMS SHALL BE REMOVED AND ALL SOLID ITEMS SHALL REMAIN, UNLESS NOTED OTHERWISE. SOME

DEMOLITION ITEMS ARE AFFECTED BY ADD ALTERNATES, AS INDICATED IN THE FLOOR PLANS. NEW WORK FLOOR PLANS

MAY CONTAIN ADDITIONAL DEMOLITION INFORMATION IN SOME LOCATIONS.
