Newmont-Cripple Creek&Victor Gold Mine ■ <br /> Technical Specification No.02200.DOCX ■ <br /> Squaw Gulch VLF <br /> Project No.475.0106.006 <br /> June 15,2016 <br /> C. Select Structural Fill <br /> 1. Select Structural Fill shall be placed for miscellaneous site grading as required by <br /> the MANAGER and CERTIFYING ENGINEER. <br /> 2. CONTRACTOR shall condition Select Structural Fill to a moisture content that allows <br /> compaction to the required density and that results in a firm, unyielding surface <br /> capable of allowing the movement of vehicles and equipment over the surface <br /> without causing rutting or other deleterious effects. <br /> 3. CONTRACTOR shall place Select Structural Fill materials with less than 30 percent <br /> rock materials above 3/4-inch size in maximum 12-inch loose lifts, and compacted <br /> to 95 percent of maximum dry density(ASTM D698). <br /> 4. CONTRACTOR shall condition and place Select Structural Fill containing more than <br /> 30 percent rock materials above 3/4-inch size (rock fill) in maximum 12-inch loose <br /> lifts and compact by a method compaction technique. The compaction equipment <br /> shall consist of a minimum ten 10-ton (static drum weight) vibratory smooth-drum <br /> compactor. The number of passes shall be subject to CERTIFYING ENGINEER's <br /> approval, at no additional cost to CC&V. The method SPECIFICATIONS may be <br /> changed at any time, at the discretion of CERTIFYING ENGINEER, based upon <br /> changes in material characteristics,field conditions, and/or compaction equipment. <br /> D. Underdrain Fill <br /> 1. Underdrain Fill shall be placed in the Underdrains as shown in the DRAWINGS. <br /> 2. CONTRACTOR shall condition Underdrain Fill that results in a firm, unyielding <br /> surface capable of allowing the movement of vehicles and equipment over the <br /> surface without causing rutting or other deleterious effects. <br /> 3. CONTRACTOR shall condition, place and compact Underdrain Fill by a method <br /> compaction technique. The compaction equipment shall consist of a minimum 10- <br /> ton (static drum weight) vibratory smooth-drum compactor. The number of passes <br /> and loose lift thickness shall be subject to CERTIFYING ENGINEER's approval, at no <br /> additional cost to CC&V. The method SPECIFICATIONS may be changed at any time, <br /> at the discretion of MANAGER, based upon changes in material characteristics, field <br /> conditions, and/or compaction equipment. <br /> 4. Provisions shall be made by CONTRACTOR for removal of oversize materials from <br /> fills, at no additional cost to CC&V. <br /> S. The MANAGER will minimize the amount of traffic over the Underdrain Fill. <br /> E. Leak Detection Fill <br /> 1. Leak Detection Fill shall be placed in the Leak Detection Trenches as shown on the <br /> DRAWINGS. <br /> Page 12 <br />
