GENERAL ELECTRICAL NOTES

1. ALL NON-FIRE RATED SURFACES ARE TO BE PATCHED WITH LIKE MATERIAL TO

MAINTAIN ORIGINAL RATING.

2. ALL PENETRATIONS THROUGH FIRE RATED SURFACES ARE TO BE SEALED WITH FIRE

CAULK TO MAINTAIN ORIGINAL RATING.

3. CONTRACTORS SHALL VISIT THE PROJECT SITE DURING PRE-BID WALK THROUGH TO

DETERMINE THE EXACT EXTENT OF THE WORK REQUIRED BEFORE BIDDING THE

PROJECT.

4. REMOVE ALL EXISTING EXPOSED CONDUIT, WIRE, AND EQUIPMENT NOT TO BE

RE-USED WHERE WORK IS BEING DONE EXCEPT ITEMS NOTED OTHERWISE.

5. EXISTING WORK WHICH IS PRESENTLY CONCEALED AND WHICH WILL REMAIN

CONCEALED AND DOES NOT INTERFERE WITH ANY NEW WORK OF ANY TRADE NEED

NOT BE REMOVED. HOWEVER, ALL CONDUIT SHALL BE CAPPED BELOW FINISH

SURFACE AND THEN PATCHED AND PAINTED TO MATCH, OR AS NOTED.

6. WHERE BUILDING SURFACES ARE DAMAGED BY THE REMOVAL OF OLD WORK,

SURFACES SHALL BE PATCHED AND PAINTED TO MATCH ADJACENT.

7. EXISTING OPENINGS, WHICH ARE TO BE REUSED, SHALL BE MODIFIED OR ENLARGED

TO SUIT THE NEW SYSTEMS AS REQUIRED. PROVIDE ALL REQUIRED CUTTING AND

PATCHING.

8. CONTRACTOR SHALL BE RESPONSIBLE FOR PATCHING THE EXISTING WALLS TO

MATCH THE ADJACENT SURFACES BEHIND ALL SURFACE MOUNTED EQUIPMENT.

9. DRAWINGS ARE BASED ON EXISTING RECORD DOCUMENTS AND CASUAL FIELD

OBSERVATION. REPORT ANY DISCREPANCIES TO ENGINEER FOR CLARIFICATION.

10. MINIMUM RACEWAY SIZE; 3/4" TRADE SIZE. ALL FLEXIBLE CONDUIT RACEWAYS SHALL

BE LIQUID TITE, MAXIMUM 36" LENGTH. REFER TO SPECIFICATION 260533 - RACEWAY

14. ALL NEW CONDUITS AND WIRES SHALL BE INSTALLED STRAIGHT AND LEVEL AND

SHALL BE PARALLEL OR PERPENDICULAR TO THE BUILDING LINES.

15. ALL NEW CONDUITS SHALL BE FIELD ROUTED ALONG EXISTING PIPING AND

STRUCTURAL STEEL.

16. ALL LOCATIONS WHERE THE WALLS CAN'T BE FISHED SHALL BE SURFACE MOUNTED

CONDUIT FOLLOWING NOTES 10 THROUGH 12 ABOVE.

17. ALL WALLS THAT ARE ACCESSIBLE SHALL BE FISHED AND DEVICE CUT INTO WALL.

18. ALL EXTERIOR CONCEALED CONDUIT UNDERGROUND SHALL BE RNC, TYPE

EPC-40-PVC

19. ALL ELECTRICAL OUTAGES SHALL NOT LAST OVER 2-HOURS. PORTABLE GENERATORS

SHALL BE USED TO REPLACE ANY ELECTRICAL SERVICE EXCEEDING THAT DURATION.

20. IN RELATION TO RELOCATING ANY ELECTRICAL DEVICE, CONTRACTOR SHALL

COMPLETE THE RELOCATION IN ONE DAY AND VERIFY THAT ALL DEVICES RELOCATED
