Newmont-Cripple Creek&Victor Gold Mine ■ <br /> Technical Specification No.02200-Earthworks ■ <br /> Concentrate Shipping <br /> Project No.475.0106.015 <br /> June 2,2017 <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, <br /> pockets, streaks, or layers of material differing substantially in texture or gradation <br /> from the surrounding material. The material of a fill shall be as described in Part 2.1 <br /> of this Section. <br /> 5. Unless otherwise approved by OWNER and CERTIFYING ENGINEER, the entire fill <br /> 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 <br /> the CONTRACTOR to prevent ponding of water and to allow for storm water <br /> drainage. <br /> 6. Except as otherwise specified or approved by the OWNER 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 <br /> shall be leveled prior to compaction by means of a dozer or grader, or other <br /> suitable approved equipment, to obtain a surface free from depressions. <br /> 7. Except in areas approved by OWNER and CERTIFYING ENGINEER where space is <br /> 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, <br /> hauling units shall be so routed that they do not follow in the same paths, but split <br /> their tracks evenly across the surface of the fill to enhance compaction. <br /> 8. CONTRACTOR shall apply water as required for moisture conditioning on the fill or <br /> in the borrow areas. <br /> CONTRACTOR shall maintain fill materials within the moisture content range <br /> required to permit proper compaction to the specified density with the equipment <br /> being used. The moisture content of the fill materials, prior to and during <br /> compaction, shall be uniform throughout each layer of the material. <br /> Prior to mixing of wet and dry material on the fill to obtain the proper moisture <br /> content, approval shall be obtained from the CERTIFYING ENGINEER. Mixed <br /> material shall have a uniform distribution of the moisture content prior to <br /> placement on the subsequent lift. <br /> When materials spread on the fill are too dry for proper compaction, CONTRACTOR <br /> shall spray water on each layer of the fill and shall work the moisture into the fill by <br /> harrowing or other approved means, until a uniform distribution of moisture is <br /> obtained. Material that is too wet for proper compaction, as determined by the <br /> CERTIFYING ENGINEER, shall be removed from the fill and/or spread out and <br /> permitted to dry, assisted by disking and harrowing or mixing in dry material when <br /> permitted by the CERTIFYING ENGINEER. This work shall be done until the moisture <br /> Page 5 <br />
