PROJECT TITLE: WATERFORD SES UNIT NO. 3 CONTRACT W3-NY-4 6.0 INSPECTION The assigned quality Verification Inspector (s) shall perform surveillance o

inspection as required to assure that the requirements listed below are fulfilled.

6.1 Material has been determined to be suitable by Ebasco and released to J. A. Jones.

6.2 Backfilling is accomplished in the proper sequence in accordance with Ebasco Drawing No. LOU-1564-G490.

6.3 Base to receive backfill has been properly prepared and compacted to the density required by Ebasco.

6.4 Sand for Class "A" fill is spread and leveled in layers not exceed-ing 15 inches' prior to compaction.

6.~ 5

' Clay for Class "A" backfill and material selected from the excavation for Class "B" backfill is placed in layers not exceeding ten inches prior to compaction.

6.6 Fill material is deposited uniformly over entire area being filled to a particular stage or level.

6.7 When required, fill material shall be disc-harrowed af ter spreading and before compaction to blend and aerate the material into a tex-ture that can be consolidated into a homogeneous mass by the com-paction operations.

6.8 Surface of each lift is kept reasonably smooth and free of ridges or grooves which would adversely affect proper compaction of subsequent.

Ilfts.

6.9 Hauling equipment uses paths different from each other in order to aid compaction of the entire area and to avoid overcompaction of any given area.
