Iron Creek and North Fork CG Water Systems Page 8 of 32

d. The number of tamper passes required may be reduced upon acceptance by the COR, if approved test method results demonstrate that the backfill compaction meets or exceeds the density of the natural ground adjacent to the trench. Any such testing shall be performed at the Contractor's expense.

4. Water compaction shall not be used.

3.02 REPAIR/RESTORATION

A. Damage to existing underground utilities.
