1.0 PURPOSE This procedure outlines a means to verify and record compliance with applicable drawings, specifications, procedures, codes, regulatory requirements and documented instruccians relating to soils inspection
~
at the construction site.
2.0 SCOPE N -
The scope of the procedure applies to safety-related items and services involving . excavation and backfill operations. The soils' control so activities will be performed in the excavated areas,' borrow-stockpile j areas, the plant backfill and earth, structure backfill areas. In-place inspections and tests as well as laboratory tests and analyses will h be performed as a combined program for control of incargrated activities a in all areas.
5 The scope of inspection activities shall be divided into two types 5 of inspection, full scale Q. C. inspection of soils operations when 13 F the Contractor does not have a Quality Assarance Program and
$ Designated R Inspection in order to monitor Contractor's performance when first-level quality Control activities are performed by the Contractor.
