AN INSPECTION TO IDENTIFY LEAD CONTAINING COATED BUILDING

COMPONENTS HAS NOT BEEN CONDUCTED BECAUSE THE BUILDING WAS

CONSTRUCTED AFTER JANUARY 1, 1985 AND THE OWNER HAS NO

KNOWLEDGE OF LEAD CONTAINING OR COATED BUILDING. IT IS THE

CONTRACTOR'S RESPONSIBILITY TO COMPLY WITH ALL VIRGINIA

GENERAL NOTES:

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

ALL CLEARANCES AND SPACES REQUIRED BY THE NEC.

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

3. SEE SPECIFICATION SECTION 260519 FOR REQUIREMENTS REGARDING OVERSIZING CONDUCTORS FOR 1-POLE 15- AND 20-AMP CIRCUITS

TO REDUCE VOLTAGE DROP. OVERSIZED CONDUCTORS FOR VOLTAGE DROP ON OTHER CIRCUITS ARE INDICATED IN THE PANEL

SCHEDULES.

4. 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.).

5. MODIFY EXISTING PANEL SCHEDULES TO ACCURATELY REFLECT ALL CHANGES MADE AS PART OF THIS CONTRACT, PROVIDE A NEW

"TYPED" PANEL SCHEDULE. PANEL SCHEDULES REVISED WITH PENCIL, PEN, OR MARKER OF ANY TYPE WILL NOT BE ACCEPTED.

6. 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 IS

MANY AREAS (PARTICULARLY ABOVE CEILINGS), AND THE CONTRACTOR SHALL BE FULLY RESPONSIBLE TO COORDINATE ALL ELECTRICAL

WORK WITH BOTH NEW AND EXISTING PIPING, DUCTWORK, ETC. NO CHANGE ORDERS WILL BE APPROVED FOR ADDITIONAL WORK DUE TO

THE CONTRACTOR NEGLECTING TO VISIT THE SITE AND GATHER ALL NECESSARY INFORMATION.

7. ALL NEW ACT CEILINGS SHALL BE INSTALLED AT THE SAME HEIGHT AS THE EXISTING ACT CEILINGS BEING REMOVED. CONTRACTOR

SHALL NOTIFY ENGINEER IMMEDIATELY IF EXISTING CEILING HEIGHTS CONFLICT WITH THE INSTALLATION OF THE NEW RECESSED LIGHT

FIXTURES EITHER DUE TO STRUCTURE ABOVE THE CEILING OR EXISTING MECHANICAL OR PLUMBING EQUIPMENT ABOVE THE CEILING.

8. ONLY DEMOLISH THE ITEMS SPECIFICALLY SHOWN WITH DASHED LINES OR NOTED TO BE DEMOLISHED ON THE DRAWINGS - ALL OTHER

EXISTING ITEMS SHALL REMAIN. COORDINATE WITH THE OWNER FOR WHICH ITEMS ARE TO BE TURNED OVER TO THE OWNER AND WHICH

ITEMS THE CONTRACTOR MAY KEEP AND REMOVE FROM THE JOB SITE.

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 CEILING MOUNTED LIGHT FIXTURES IN THE RENOVATION AREA ARE REMOVED AND REINSTALLED (DUE TO HVAC WORK)

IN AN ACCESSIBLE CEILING GRID AND THEY ARE NOT PROVIDED WITH SEPARATE STRUCTURAL SUPPORT FROM THE BUILDING

STRUCTURAL FRAMING MEMBERS ABOVE, THE CONTRACTOR SHALL PROVIDE LIGHT FIXTURE SUPPORTS FOR THESE EXISTING LIGHT

FIXTURES THAT MEET THE CODE.

11. ALL EXTERIOR WALL PENERATIONS SHALL BE WEATHER/WATER TIGHT.

12. THE CONTRACTOR IS RESPONSIBLE FOR ANY DAMAGE, PATCHING TO EXTERIOR AND INTERIOR WALLS, CEILING, CEILING TILES, FLOORS, DUCTBANKS, ETC. THAT WAS DAMAGED UNDER THIS SCOPE OF WORK.

13. THE CONTRACTOR SHALL PROVIDE FIRE STOPS PRODUCT SYSTEM WHEN PENETRATING AN FIRE RATED ASSEMBLY.

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 ALL EXISTING

ELECTRICAL SYSTEMS IN THE AREAS OF RENOVATION, EXCEPT AS NOTED OTHERWISE IN THESE NOTES AND ON THE DRAWINGS.

2. FIRE ALARM SYSTEM : THE EXISTING FIRE ALARM SYSTEM SHALL REMAIN. ALL ITEMS ASSOCIATED WITH THE EXISTING SYSTEM

(DEVICES, CONTROL PANELS, POWER SUPPLIES, WIRING, ETC.) SHALL BE REMAIN, EXCEPT WHERE SPECIFICALLY INDICATED

OTHERWISE. CONTRACTOR IS RESPONSIBLE FOR ALL TESTING AS NOTED ON THE CONTRACT DOCUMENTS COVERED UNDER THIS

SCOPE OF WORK.

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 SHALL REMAIN, NO NEW LOADS OR ADDITIONAL LOADS WITH THE REPLACEMENT IN

KIND MECHANICAL EQUIPMENT.

5. CONDUIT : WHERE EXISTING CONDUIT IS EXPOSED DUE TO DEMOLITION OF WALLS, CONDUIT SHALL BE REMOVED, UNLESS INDICATED

TO REMAIN OR NECESSARY TO MAINTAIN SERVICE TO EXISTING ITEMS TO REMAIN. WHERE CONDUIT RISES FROM FLOOR TO FEED

REMOVED ITEMS, CUT CONDUIT FLUSH WITH FLOOR AND FILL IT WITH GROUT. FINISH TO MATCH FLOOR SURFACE. 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.

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

7. 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.

8. THE CONTRACTOR SHALL VISIT THE SITE PRIOR TO SUBMITTING RED 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.

9. 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 ADDITIVE BID ITEM, AS INDICATED IN THE FLOOR PLANS. NEW WORK FLOOR PLANS MAY CONTAIN ADDITIONAL

DEMOLITION INFORMATION IN SOME LOCATIONS.
