of the building that enter a building, preferably to building grounds at
points where pipes enter the building. Where a separate ground is
provided, bond the pipes to the building ground at points where the pipes
are closest to the ground connections. In addition, bond pipes to any
metallic masses that are within 1830 mm 6 feet of the pipe.

Where sod has been removed, place sod as soon as possible after completing
the backfilling. Restore to original condition the areas disturbed by
trenching, storing of dirt, cable laying, and other work. Include
necessary topsoiling, fertilizing, liming, seeding, sodding, sprigging or
mulching in any restoration. Maintain disturbed surfaces and replacements
until final acceptance.

FIELD QUALITY CONTROL
3.5.1
Grounding System Test
Test the grounding system to ensure continuity and that resistance to
ground is not in excess of [10] [_____] ohms. Test the ground rod for
resistance to ground before making connections to the rod. Tie the
grounding system together and test for resistance to ground. Make
resistance measurements in dry weather, not earlier than 48 hours after
rainfall. Include in the written report: locations of ground rods,
resistance, and soil conditions at the time that measurements were made.
Submit results of each test to the Contracting Officer.
3.5.2
Make visual inspections to verify that there are no loose connections which
may result in high resistance joints, and that conductors and system
components are securely fastened to their mounting surfaces and are
protected against accidental mechanical displacement.
