APPENDIX B <br />• Guide Si:ecifications for Placement of_COmpactud Fi71 <br />GENERAL <br />A soils engineer shall be the owner's representative to observe and test <br />the earthwork placement, moisture content and compaction. T}rc soils <br />enyinaer shall review the fill materials and the method.. ui 11JCing and <br />compaction and shall give written results of observat.rons an.l tact <br />results. <br />_C LEA RI AIG AREA TO_BG FILL6: I7 <br />All vegetation, rubbish, and other deleterious matter shall 7„ cenlo vet, <br />from the area to receive fill, and disposed of. frozen mntctiJl ohall <br />be removed.

Additionally, the contractor shall not hl.a ce <br />backfill material which exceeds the maximum moisture content specifica- <br />tion, unless the material is left to aereate or blended with drier <br />material to achieve the specified moisture content.
