WATERFORD STEAM KLECTRIC STATION - UNIT NC 3 PACE: 1 0F 10 1.0 PURPOSE This procedure outlines a means to verify and record conpliance with applicable drawings, specifications, procedures, codes, regulatory requirements and documented instructions relating to soils in n ection at the construction site.
2.0 SCOPE The scope of the procedura ci ab as to safety-related items and services involving excavation and bac.:~311 operations. The soils control activities will be performed in the excavated areas, borrow-stockpile as{
areas, the plant backfill and earth structure backfill areas. In-place inspections and tests as well as laboratory tests and analyses will be h.a performed as a combined program for control of intergrated activities in au areas.
as g
The scope of inspection activities shall be divided into two types of inspection, full scale Q.C. inspection of soils operations when the E
Contractor does not have a Quality Assurance Program and Designated Inspection in order to monitor Contractor's performance when first-level Quality Control activities are performed by the Contractor.
