6.0 INSPECTION The assigned Quality Verification Inspector (s) shall perform surveillance inspection as required to assure that the requi rements listed.below are ful fi l l ed.

6.1 Material has been detennined 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.

g,gl 6.4 Sand and clam shell for Class "A" fill is spread and layers not exceeding 15 inches prior to compaction.

leveled in 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 i s deposited uniformly over entire area being filled to a particular stage or level.

6.7 When required, fill material shall be disc-harrowed after spreading l and before compaction to blend and aerate the material into a tex- --

L ture that can be consolidated into a homogeneous miss by the com-paction operations. e. <

6.8 Surface of each lift is kept reasonable smooth' and f ree of ridges or groves which would adversely affect proper compaci ton of subsequent lifts.

l 6.9 Hauling equipment uses paths dif ferent from each other in order to aio compaction of the entire area and to avoid overcompaction of any given area.
