These are engineering design drawings for a ground bonding winch motor project at Marine Corps Air Station Cherry Point in North Carolina. The project involves electrical and concrete work for Building 3957, specifically focusing on grounding wire installation and connection. The drawings (sheets G-001, E-101, and CU01) detail the scope of work, including cutting a 1' x 1' x 6" section in existing concrete to reconnect and repair the equipotential bonding ground wire, installing a new ground wire in 1" PVC conduit along the platform structure, and ensuring proper grounding connections meet NEC requirements. The project is part of Work Order 7500764, with a final design date of 07.02.2025, and is restricted to M&R MACC (Maintenance and Repair Multiple Award Construction Contract) contractors.

GENERAL NOTES:

1. CONDUIT SHALL BE PROVIDED AND INSTALLED NOT TO INHIBIT AND/OR

OBSTRUCT THE ACCESS INTO CEILINGS AND TO SERVICE, OR REPAIR

2. CONTRACTOR SHALL SURVEY AND LOCATE ALL UNDERGROUND UTILITIES

WITHIN THE WORK AREA

3. MEET REQUIREMENTS FOR GROUND WIRE IN NEC 680.26A AND NEC

680.26B

4. PRIOR TO WELDING, CONFIRM THAT THE BONDING GRID OR COPPER

WIRE IS CONDUCTIVE AND ELECTRICALLY CONTINUOUS WITH A

RESISTANCE OF LESS THAN 100 MILLI OHMS.

5. TEST GROUNDING SYSTEM TO ENSURE CONTINUITY, AND THAT

RESISTANCE TO GROUND IS NOT EXCESSIVE. TEST EACH GROUND ROD

FOR RESISTANCE TO GROUND BEFORE MAKING CONNECTIONS TO ROD;

TIE GROUNDING SYSTEM TOGETHER AND TEST FOR RESISTANCE TO

GROUND. MAKE RESISTANCE MEASUREMENTS IN DRY WEATHER, NOT

EARLIER THAN 48 HOURS AFTER RAINFALL. SUBMIT WRITTEN RESULTS

OF EACH TEST TO CONTRACTING OFFICER, AND INDICATE LOCATION OF

ROADS AS WELL AS RESISTANCE AND SOIL CONDITIONS AT TIME

MEASUREMENTS WERE MADE.
