About this file

This is a set of architectural and engineering drawings for an electrical construction project at a bio-laboratory facility.

The project, titled "Balance 3 Phase Power at Bio-Lab," involves eliminating single-phase loading and restoring balanced three-phase loading at the service entrance. Key work includes: providing a new 3-phase, 4-wire, 208Y/120V panel labeled "Main-2" sized at 225 amperes; installing a new 3-pole feeder breaker in the existing "Main-1" panel; running new feeder conductors from "Main-1" to "Main-2" consisting of three phase conductors, one neutral conductor, and one equipment grounding conductor in conduit; splicing new service conductors to existing 500 KCMIL service conductors using mechanical or compression connectors; converting the existing "Main-2" enclosure to a junction/splice enclosure with removal of overcurrent devices; providing listed insulated terminal blocks for termination and splicing within the existing "Main-2" enclosure rated for 600V and 75 degrees Celsius minimum; establishing an isolated neutral bar and bonded ground bar within "Main-2"; balancing branch circuits across all three phases at the new "Main-2" panel to maximum practical extent; and bonding and grounding "Main-2" per NEC requirements. The work also requires verification of phase rotation and system voltage, updated panel schedules and circuit directories, fire-retardant treated exterior-grade plywood backboard installation where "Main-2" is located, and de-energization and lockout/tagout procedures for existing single-phase panel "Main-2" prior to work. All work is located within Building 45 unless otherwise noted, with de-energization of electrical service potentially requiring operations at existing exterior utility equipment.

TITLE SHEET

GENERAL NOTES:

1. ALL WORK SHOWN ON THESE DRAWINGS IS LOCATED WITHIN

BUILDING 45 UNLESS OTHERWISE NOTED. DE-ENERGIZATION OF THE

ELECTRICAL SERVICE MAY REQUIRE OPERATIONS AT EXISTING

EXTERIOR UTILITY EQUIPMENT, INCLUDING POLE-MOUNTED FUSE

CUTOUTS. NO NEW EXTERIOR CONSTRUCTION IS INCLUDED IN THE

SCOPE OF WORK.

2. PRIOR TO SUBMISSION OF MATERIAL SUBMITTALS, THE CONTRACTOR

SHALL FIELD-VERIFY EXISTING CONDUCTOR SIZES, MATERIALS,

INSULATION TYPES, AVAILABLE CONDUCTOR LENGTHS, AND PHASE

ROTATION. ANY DISCREPANCIES SHALL BE REPORTED TO THE

GOVERNMENT PRIOR TO PROCUREMENT OR INSTALLATION.

3. THE CONTRACTOR SHALL REMOVE THE SERVICE CONDUCTOR

TROUGH COVER AS REQUIRED TO INVESTIGATE EXISTING SPLICES,

CONDUCTOR SIZES, AND INSULATION CONDITIONS PRIOR TO

PREPARING MATERIAL SUBMITTALS. RESTORE ALL COVERS UPON

COMPLETION OF INVESTIGATION.

4. THE CONTRACTOR SHALL PROVIDE ALL REQUIRED SIGNAGE,

BARRIERS, AND PROTECTIVE MEASURES TO PREVENT UNAUTHORIZED

ACCESS TO WORK AREAS. WORK AREAS, TOOLS, AND EQUIPMENT

SHALL NOT BE LEFT UNATTENDED AND SHALL BE SECURED WHEN THE

SITE IS NOT OCCUPIED.

5. POWER OUTAGES REQUIRED FOR INVESTIGATION, TESTING, AND

INSTALLATION OF NEW EQUIPMENT SHALL BE LIMITED TO A MAXIMUM

DURATION OF EIGHT (8) HOURS. FOR OUTAGES SCHEDULED TO

EXCEED ONE (1) HOUR, THE CONTRACTOR SHALL PROVIDE TWO (2) 5

KW GENERATOR AND EXTENSION CORDS AS NEEDED TO MAINTAIN

POWER TO LABORATORY REFRIGERATORS AND FREEZERS.

6. POWER FOR HAND TOOLS AND CHARGING OF BATTERY-POWERED

TOOLS IS AVAILABLE IN THE BUILDING MAIN ELECTRICAL ROOM.

CONTRACTOR SHALL COORDINATE ACCESS AND KEYS WITH THE

GOVERNMENT.

7. WORK ON ENERGIZED ELECTRICAL EQUIPMENT IS NOT PERMITTED.

ALL ELECTRICAL WORK SHALL BE PERFORMED WITH EQUIPMENT

DE-ENERGIZED, LOCKED OUT, AND VERIFIED SAFE PRIOR TO

COMMENCING WORK.

8. THE CONTRACTOR SHALL PROVIDE ALL PERSONNEL, EQUIPMENT,

PPE, AND SPECIALTY TOOLS REQUIRED TO PERFORM SCHEDULED

POWER OUTAGES. ALL OUTAGES SHALL BE COORDINATED AND

APPROVED BY THE GOVERNMENT IN ADVANCE.

9. UNLESS OTHERWISE NOTED THE OVERHEAD UTILITY LINES AND

UNDERGROUND UTILITY LINES ARE THE PROPERTY OF THE

GOVERNMENT. PROVIDE ALL PERSONNEL AND EQUIPMENT TO

PERFORM THE REQUIRED POWER OUTAGES (ELECTRICIAN, HIGH

VOLTAGE ELECTRICIAN, BUCKET TRUCK, PPE, ETC). SCHEDULE AND

COORDINATE REQUIRED POWER SHUTDOWNS WITH GOVERNMENT.
