Reopen improperly backfilled trenches, and trenches that show sinking within 12 months after Substantial Completion to the depth required for proper compaction, then refill and compact as specified. The meaning of "density of the adjacent soil" when the adjacent formation is rock shall be interpreted as maximum density. The surface shall be restored to its original condition as near as practicable and as hereinafter specified. Replace sidewalks, curbs, gravel, pavement, base course, and compacted subgrade disturbed by trenching operations.
