Newmont-Cripple Creek & Victor Gold Mine <br />Technical Specification No. 02200-1 EARTHWORKS – Owner Performed Work <br />VLF2 Phase 3 <br />Project No.475.0106.049 <br />September 13, 2023 <br /> <br /> <br /> <br />Technical Specification No.02200-1 Earthworks – Owner Performed Work Page 5 <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 Section <br />2.1 of this specification. <br />5. Unless otherwise approved by MANAGER 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 MANAGER and CERTIFYING ENGINEER, <br />the CONTRACTOR shall dump and spread fill in such a manner so that no excessive <br />gaps are left between successively dumped loads of materials. The fill shall be leveled <br />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 <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 required for moisture conditioning on the fill or in <br />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 CERTIFYING ENGINEER. Mixed material <br />shall have a uniform distribution of the moisture content prior to placement on the <br />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 <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 CERTIFYING ENGINEER, if necessary, until the moisture content is <br />reduced to an amount suitable for obtaining the specified degree of compaction, at <br />no cost to CC&V.
