such material shall be removed to the limits directed by the Geotechnical Inspector and/or the
City Inspector and the resulting excavation backfilled with pipe bedding material.
B. Backfill materials shall be brought to or maintained at an appropriate moisture content for
compaction. The appropriate moisture content range shall be established at the onset of the

C. The first length of trench backfilled shall be backfilled in the presence of the City Inspector.
Compaction shall be tested at random depths at approximate three-foot vertical intervals as
