amec <br />the top layer can be compacted as required. The recompacted surface shall then be scarified, as <br />needed, to provide a good bond between the foundation and fill materials. <br />3.06 FILL PLACEMENT: <br />A. The following general guidelines shall be followed except as noted elsewhere in this Section. <br />Section 02200 <br />Earthworks <br />1. No fill materials shall be placed until the foundation and subgrade preparations have been <br />completed as specified herein, in Article 3.05 of this Section. The procedures for fill <br />placement shall be approved by MANAGER and CERTIFYING ENGINEER prior to <br />start of fill placement. <br />2. No brush, roots, sod, frozen material, or other deleterious or unsuitable materials shall be <br />incorporated in the fills. The suitability of all materials intended for use in the fill shall be <br />subject to approval by MANAGER and CERTIFYING ENGINEER. Fill placement <br />shall be temporarily stopped by CONTRACTOR due to weather conditions, if materials <br />and installation do not meet the SPECIFICATIONS, at no cost to CC &V. Fill shall not be <br />placed upon frozen material, such as snow or ice. <br />3. If the surface of the prepared foundation or the surface of any layer of the fill is too dry or <br />too smooth to bond properly with the layer of material to be placed thereon, it shall be <br />moisture- conditioned and/or worked with harrow, scarifier, disc, or other suitable <br />equipment to provide a satisfactory bonding surface before fill material is placed thereon. If <br />the surface of the prepared foundation or the rolled surface of any layer is excessively wet <br />for fill materials to be placed thereon, it shall be removed and allowed to dry or worked <br />with a harrow, scarifier, disc, or other suitable equipment to reduce the moisture content to <br />an acceptable level or meet project specifications as determined by MANAGER and <br />CERTIFYING ENGINEER. It shall then be compacted before the next layer of fill <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 />5. 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 <br />is limited or otherwise specified, CONTRACTOR shall place fill by routing the hauling <br />and 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 <br />evenly across the surface of the fill to enhance compaction. <br />Page 6 of 14 <br />June 19, 2012 <br />Revision 1 <br />
