GENERAL NOTES:

1. NEW ACCESS FLOOR TILES SHALL BE INSTALLED FLUSH WITH ADJACENT EXISTING

TILES THAT REMAIN. PROVIDE DETAILS IN CONTRACTOR-GENERATED INSTALLATION

PLANS.

2. WALLS WILL BE PENETRATED WHERE SRG SYSTEM TIES TO OTHER SPACES. SEAL

OPENINGS TO PROPERLY MAINTAIN REQUIRED/EXISTING FIRE, SOUND AND

SECURITY RATINGS. PROVIDE DETAILS IN CONTRACTOR-GENERATED INSTALLATION

PLANS.

3. SEE "PERFORMANCE WORK STATEMENT" (PWS) AND ITS APPENDICES FOR

INFORMATION CONCERNING:

-- "RIGID GRID ACCESS FLOORING" DETAILING, INSTALLATION AND SPECIFICATIONS

(APPENDIX B). PROVIDE INSTALLATION PLANS PER REQUIREMENTS OF APPENDIX B.

-- "ENCAPSULATION OF SUB-FLOOR" (CONCRETE SEALER) INSTALLATION AND

SPECIFICATIONS (APPENDIX C).

-- "SIGNAL REFERENCE GRID FOR GROUNDING (SRG) DETAILING, INSTALLATION AND

SPECIFICATIONS (APPENDIX D). SRG SHALL BE ATTACHED TO THE ACCESS FLOOR

SYSTEM PEDESTALS, JUST BELOW THE FLOOR TILES - FOLLOW INFORMATION/

DETAILING IN SECTION "5.3.2 SECURE SRG TO FLOOR PEDESTALS (EXISTING

ACCESS-FLOOR).

-- "MIL-STD-188" FOR DETAILING, INSTALLATION AND SPECIFICATIONS FOR

GROUNDING, BONDING AND SHIELDING (APPENDIX I).

-- "ELECTRIC SAFETY PROGRAM" WHICH PERTAINS TO ALL EMPLOYEES AND

CONTRACTORS AT THE FACILITY, WHO PLAN, PERFORM, SUPERVISE, AND/OR

EXECUTE ELECTRICAL WORK, OR WORK IN THE VICINITY OF ELECTRICAL

SYSTEMS.

4. WHERE CUT-OUTS ARE REQUIRED IN FLOOR PANELS TO ALLOW FOR I.T. AND POWER

CABLING:

-- PROVIDE/INSTALL FLUSH MOUNTED GROMMETS WITH BRUSHES (TO SEAL-OFF

AIR FLOW) TO COVER CUTOUTS IN ACCESS FLOOR PANELS. GROMMETS SHALL BE

EITHER CUT IN HALF, OR BE 2-PIECE NESTING UNITS - TO ALLOW FOR EASY

REMOVAL OF FLOOR PANELS, WHILE ALLOWING CABLING TO REMAIN IN PLACE.

GROMMETS SHALL BE EITHER KOLDLOK 1010 (CUT IN HALF) OR KOLDLOCK 3030

(2-PIECE), OR APPROVED EQUAL.

-- FLOOR PANEL CUT-OUTS SHALL BE ON EDGES OF PANELS. NO CENTER HOLES

IN PANELS ARE ALLOWED FOR CABLE ACCESS. THIS WILL ALLOW FLOOR PANELS

TO BE REMOVED, WHILE ALLOWING CABLING TO REMAIN IN PLACE.

5. DEMOLISH THE EXISTING GROUNDING "X" GRID FROM THE CONCRETE SUB-FLOOR

AREAS COVERED BY THIS PROJECT (113, 113A, 117, 118, 125). THIS GRID IS RUN

CROSS CORNERS OF EACH STRUCTURAL GRID, AND CLAMPED/CONNECTED TO

FLOOR PEDESTALS.

-- A GROUNDING SURVEY SHALL BE CONDUCTED AND ALL FINDINGS SHALL BE

DOCUMENTED.

-- INSTALL NEW GROUNDING MATERIALS AS /IF REQUIRED IN ORDER TO ASSURE THE

EXISTING GROUNDING "X" GRID, WHICH REMAINS IN ADJACENT AREAS, IS STILL A

FUNCTIONAL GROUNDING SYSTEM.

-- IN THE AREA OF THIS PROJECT, IF ANY EQUIPMENT, OTHER THAN I.T. ITEMS OR

RAISED FLOORING, ARE FOUND TO BE CONNECTED TO THE EXISTING GROUNDING

"X" GRID, THEY SHALL BE PROPERLY GROUNDED AS PART OF THIS PROJECT.
