AN <br />ame <br />material is placed. Determination of such dry or wet conditions shall be made by <br />CERTIFYING ENGINEER. <br />4. The distribution of materials shall be such that the fill is free from voids, lenses, pockets, <br />streaks, or layers of material differing substantially in texture or gradation from the <br />surrounding material. The material of a fill shall be as described in Article 2.01 of this <br />Section. <br />Unless otherwise approved by MANAGER and CERTIFYING ENGINEER, the entire <br />fill surface shall be at or near the same elevation at all times during construction. At all <br />times during construction, the surface of the fill shall be graded and maintained by the <br />CONTRACTOR to prevent ponding of water and to allow for storm water drainage. <br />6. Except as otherwise specified or approved by MANAGER and CERTIFYING <br />ENGINEER, the CONTRACTOR shall dump and spread fill in such a manner so that no <br />excessive gaps are left between successively dumped loads of materials. The fill shall be <br />leveled prior to compaction by means of a dozer or grader, or other suitable approved <br />equipment, to obtain a surface free from depressions. <br />7. Except in areas approved by MANAGER and CERTIFYING ENGINEER where space is <br />limited or otherwise specified, CONTRACTOR shall place fill by routing the hauling and <br />spreading units approximately parallel to the axis of the fill. As far as practical, hauling <br />units shall be so routed that they do not follow in the same paths, but split their tracks evenly <br />across the surface of the fill to enhance compaction. <br />8. CONTRACTOR shall apply water required for moisture conditioning on the fill or in the <br />borrow areas. <br />CONTRACTOR shall maintain fill materials within the moisture content range required to <br />permit proper compaction to the specified density with the equipment being used. The <br />moisture content of the fill materials, prior to and during compaction, shall be uniform <br />throughout each layer of the material. <br />Prior to mixing of wet and dry material on the fill to obtain the proper moisture content, <br />approval shall be obtained from CERTIFYING ENGINEER. Mixed material shall have a <br />uniform distribution of the moisture content prior to placement on the subsequent lift. <br />When materials spread on the fill are too dry for proper compaction, CONTRACTOR shall <br />spray water on each layer of the fill and shall work the moisture into the fill by harrowing or <br />other approved means, until a uniform distribution of moisture is obtained. Material that is <br />too wet for proper compaction, as determined by CERTIFYING ENGINEER, shall be <br />removed from the fill and/or spread out and permitted to dry, assisted by disking and <br />harrowing or mixing in dry material when permitted by CERTIFYING ENGINEER, if <br />necessary, until the moisture content is reduced to an amount suitable for obtaining the <br />specified degree of compaction, at no cost to CC &V. <br />After each layer of fill material has been placed, spread, and moisture - conditioned, the layer <br />shall be compacted by passing compaction equipment over the entire surface of the layer a <br />sufficient number of times to obtain the required density, as specified herein. <br />Compaction shall be accomplished with equipment and by methods approved by <br />CERTIFYING ENGINEER. If such equipment or methods are found unsatisfactory for <br />Section 02200 Page 8 of 18 September 3, 2008 <br />Earthworks Revision 1 <br />SAProjects\1125E CCV CQA \I - Tech SpecsX02200.ri.doc <br />
