3.06 FILL PLACEMENT: • A. The following general guidelines shall be followed except as noted elsewhere in this Section. No fill materials shall be placed until the foundation and subgmde preparations have been completed as specified herein, in Article 3.05 of this Section. The procedures for fill placement shall be approved by MANAGER and CERTIFYING ENGINEER prior to start of fill placement. 2. No brash, roots, sod, frozen material, or other deleterious or unsuitable materials shall be incorporated in the fills. The suitability of all materials intended for use in the fill shall be subject to approval by MANAGER and CERTIFYING ENGINEER. Fill placement shall be temporarily stopped by CONTRACTOR due to weather conditions, if materials and installafion do not meet the SPECIFICATIONS, at no cost to CC&V. Fill shall not be placed upon frozen material, such as snow or ice. 3. If the surface of the prepared foundation or the surface of any layer of the fill is too dry or too smooth to bond properly with the layer of material to be placed thereon, it shall be moisture-conditioned and/or worked with harrow, scarifier, diso, or other suitable equipment to provide a satisfactory bonding surface before fill material is placed thereon. If the surface of the prepared foundation or the rolled surface of any layer is excessively wet for fill materials to be placed thereon, it shall be removed and allowed to dry or worked with a harrow, scarifier, disc, or other suitable equipment to reduce the moisture content to an acceptable level or meet project specificationsas determined by MANAGER and CERTIFYING ENGINEER. It shall then be compacted before the next layer of fill material is placed. Determination of such dry or wet conditions shall be made by CERTIFYING ENGINEER. • 4. The distribution of materials shall be such that the fill is free from voids, lenses, pockets, streaks, or layers of material differing substantially in texture or gradation from the surrounding material. The material of a fill shall be as described in Article 2.01 of this Section. 5. Unless otherwise approved by MANAGER and CERTIFYING ENGINEER, the entire fill surface shall be at or neaz the same elevation at all times during constmction. At all times daring constmction, the surface of the 511 shall be graded and maintained by the CONTRACTOR to prevent ponding of water and to allow for storm water drainage. 6. Except as otherwise specified or approved by MANAGER and CERTIFYING ENGINEER, the CONTRACTOR shall dump and spread fdl in such a manner so that no excessive gaps are left between successively-dumped loads of materials. The fill shall be leveled prior to compaction by means of a dozer or grader, or other suitable approved equipment, to obtain a surface free from depressions. 7. Except in areas approved by MANAGER and CERTIFYING ENGINEER where space is limited or otherwise specified, CONTRACTOR shall place fill by routing the hauling and spreading units approximately parallel to the axis of the fill. As faz as practical, hauling units shall be so routed that they do not follow in the same paths, but split their tracks evenly across the surface of the fill to enhance compaction. 8. CONTRACTOR shall apply water required for moisture conditioning on the fill or in the borrow areas. • CONTRACTOR shall maintain fill materials within the moisture content range required to permit proper compaction to the specified density with the equipment being Section 02200 Page 7 of 17 March 22, 2000 Earthworks Golder Associates Revision 7 I1 W~2203WOOUCFATAEP0863W PPEND541PPED2200A'IDOC
