1. THE WORK OUTLINED IN THESE DRAWINGS WILL BE PERFORMED IN NO MORE THAN TWO (2) POWEROUTAGES. EACH POWER OUTAGE IS LIMITED TO A MAXIMUM OF TWELVE (12) HOURS EACH BETWEENTHE TIME THAT POWER IS TURNED OFF AND POWER IS RESTORED. EACH OUTAGE SHALL BECOORDINATED WITH THE OWNER AS TO TIME AND DATE NO LESS THAN TWO (2) WEEKS IN ADVANCEAND SHALL BE PERFORMED IN TWO CONSECUTIVE DAYS. THE FIRE STATION SHALL BE OCCUPIED BYPERSONNEL EACH DAY AND SHALL BE FULLY OPERATIONAL AT THE OF EACH POWER OUTAGE.
2. POWER OUTAGE #1 WILL INCLUDE THE FOLLOWING WORK:
A. PROVIDE NEMA 3R VENTILATED PANEL "MDP" ON BUILDING EXTERIOR AND CONNECT TO "ATS". B. PROVIDE PANEL "MDP" PANELBOARD FEEDERS AND BRANCH CIRCUITS.C. PROVIDE TEMPORARY PANELBOARD FEEDER TO EXISTING PANEL "B" UNTIL POWER OUTAGE #2.D. PROVIDE NEW GROUNDING ELECTRODE CONNECTION TO METAL WATER PIPE.E. PROVIDE NEW PANEL "A" WITH TOP AND BOTTOM WIREWAYS AND RECONNECT ALL BRANCH
CIRCUITS SAVED DURING DEMOLTION.
3. POWER OUTAGE #2 WILL INCLUDE THE FOLLOWING WORK:
A. PROVIDE NEW PANEL "B" WITH TOP WIREWAY AND RECONNECT ALL BRANCH CIRCUITS SAVED DURING DEMOLITION.B. PROVIDE PERMANENT PANEL "B" FEEDER.C. PERFORM ANY REMAINING WORK REQUIRED BY BID DOCUMENTS AND PROJECT SPECIFICATIONS.

GENERAL DEMOLITION NOTES:
8.
PERFORM ALL REQUIRED DEMOLITION TO COMPLY WITH THE SCOPE AND INTENT OF THE PROJECT.REMOVE ALL WIRING ASSOCIATED WITH THE REQUIRED DEMOLITION BACK TO POINT OF ORIGIN ORLAST DEVICE TO REMAIN
VERIFY ALL CIRCUITS SAVED DURING DEMOLITION FOR REUSE AS TO WIRE SIZE AND POINT OFORIGIN.
EXERCISE CARE IN REMOVING MATERIAL AND EQUIPMENT DURING DEMOLITION. REPAIR ALLDAMAGES TO EXISTING SURFACES OR EXISTING EQUIPMENT TO REMAIN TO THE SATISFACTION OFTHE ENGINEER AND OWNER AT NO ADDITIONAL COST TO THE OWNER.
PROVIDE THE OWNER WITH FIRST RIGHT OF REFUSAL FOR ALL ELECTRICAL EQUIPMENT BEINGREMOVED AS A PART OF THIS CONTRACT AND NOT SCHEDULED FOR REINSTALLATION. ALLELECTRICAL EQUIPMENT NOT TURNED OVER TO THE OWNER SHALL BECOME THE PROPERTY OF THEELECTRICAL CONTRACTOR AND SHALL BE REMOVED FROM THE SITE.
THE ELECTRICAL CONTRACTOR IS RESPONSIBLE FOR THE REMOVAL OF EXISTING CEILING TILES ASREQUIRED TO INSTALL NEW BRANCH CIRCUITRY. REINSTALL EXISTING CEILING TILES AFTERCOMPLETION OF WORK. REPLACE ALL CEILING TILES DAMAGED DURING THIS PROJECT WITH NEWTILES TO MATCH EXISTING TO THE SATISFACTION OF THE ENGINEER AND OWNER.
PROVIDE ALL ELECTRICAL DEMOLITION WORK NECESSARY TO INSTALL NEW WORK. REROUTE ANDRECONNECT ALL CIRCUITS THAT ARE REQUIRED TO REMAIN IN USE BUT INTERFERES WITH NEWCONSTRUCTION.
CONDUITS MAY BE ABANDONED IN WALLS AND BELOW FIRST FLOOR SLABS ONLY. REMOVE ALLWIRING FROM ABANDONED CONDUITS. DISCONNECT CONDUCTORS FROM ALL POWER SOURCESAND PROVIDE BLANK COVERPLATES ON ALL ABANDONED OUTLET BOXES.
WHERE THE TERM "BRANCH CIRCUITRY" IS USED ON THESE DRAWINGS, IT IS TO BE CONSTRUED TOMEAN CONDUIT AND CONDUCTORS.
EXISTING CONDITIONS ILLUSTRATED HAVE BEEN DETERMINED FROM ORIGINAL CONSTRUCTIONDOCUMENTS AND LIMITED NON-INVASIVE FIELD INVESTIGATION. CONTRACTOR SHALL INVESTIGATEFIELD CONDITIONS PRIOR TO COMMENCEMENT OF WORK, COORDINATE AND MAKE ADJUSTMENTS ASNECESSARY.
1.
GENERAL NOTES:WHERE INDIVIDUAL 120V HOMERUN CIRCUITS ARE SHOWN ON THE DRAWINGS THEY MAY BECOMBINED AS FOLLOWS: - NO MORE THAN THREE (3) PHASE CONDUCTOR PLUS THREE NEUTRALS AND ONE (1) GROUND PER CONDUIT, EXCEPT WHERE SPECIFICALLY NOTED OTHERWISE. - NO TWO OF THE SAME PHASE CONDUCTOR PER CONDUIT. - PROVIDE 120V CIRCUIT WITH INDIVIDUAL NEUTRALS PER CIRCUIT. NEUTRALS MAY NOT BE SHARED BETWEEN PHASES.
PAINT ALL EXPOSED CONDUIT AND SURFACE METAL RACEWAY TO MATCH THE SURFACE TO WHICHATTACHED.
PROTECT BRANCH CIRCUIT WIRING FROM PAINT OVERSPRAY DURING CONSTRUCTION TO PRESERVECOLOR-CODING. CONDUCTORS PAINTED SHALL BE COMPLETELY CLEANED OF PAINT BEFORE FINALCONNECTIONS ARE MADE.
COORDINATE WIRING DEVICE OUTLET LOCATIONS WITH ELECTRICAL PLANS, ELEVATIONS AND JOBSITE DIFFERENCES PRIOR TO ROUGHING-IN CONDUITS. MAKE REQUIRED ADJUSTMENTS (WITH THEENGINEERS APPROVAL).
INSTALL DEVICES SHOWN ON DRAWINGS IN ACCORDANCE WITH MOUNTING HEIGHTS SHOWN IN THEELECTRICAL LEGEND AND/OR THE PROJECT SPECIFICATIONS. ALL MOUNTING HEIGHT DIMENSIONSARE TO THE CENTER OF THE OUTLET BOX, UNLESS OTHERWISE NOTED.
FOR RECEPTACLE LOCATIONS WITHIN 6 FEET OF A LAVATORY, SINK, WATER CLOSET, SHOWERSTALL, OR ANY WATER USING APPLIANCE, PROVIDE GROUND FAULT INTERRUPTING TYPERECEPTACLES.
CIRCUIT BREAKERS SERVING ELECTRIC WATER COOLERS SHALL BE GROUND FAULT INTERRUPTINGTYPE.
