Section 02200 <br />Earthworks <br />2. CONTRACTOR shall condition Structural Fill to a moisture content that allows <br />compaction to the required density and that results in a firm, unyielding surface capable of <br />allowing the movement of vehicles and equipment over the surface without causing rutting <br />or other deleterious effects. <br />3. CONTRACTOR shall place Structural Fill materials with less than 30 percent rock <br />materials above 3/4 -inch size in maximum 12 -inch loose lifts, and compact to 95 percent of <br />maximum dry density (ASTM D698). <br />4. CONTRACTOR shall condition, place and compact Structural Fill containing more than <br />30 percent rock materials above 3/4 -inch size (rock fill) by a method compaction technique. <br />The compaction equipment shall consist of a minimum 10 -ton (static drum weight) <br />vibratory smooth -drum compactor. The number of passes and loose lift thickness shall be <br />subject to CERTIFYING ENGINEER's approval, at no additional cost to CC &V. The <br />method SPECIFICATIONS may be changed at any time, at the discretion of <br />CERTIFYING ENGINEER, based upon changes in material characteristics, field <br />conditions, and/or compaction equipment. <br />C. Select Structural Fill <br />1. Select Structural Fill shall be placed for miscellaneous site grading as required by the <br />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 capable of <br />allowing the movement of vehicles and equipment over the surface without causing rutting <br />or other deleterious effects. <br />3. CONTRACTOR shall place Select Structural Fill materials with less than 30 percent rock <br />materials above 3/4 -inch size in maximum 12 -inch loose lifts, and compacted to 95 percent <br />of maximum dry density (ASTM D698). <br />4. CONTRACTOR shall condition and place Select Structural Fill containing more than 30 <br />percent rock materials above 3/4 -inch size (rock fill) in maximum 12 -inch loose lifts and <br />compact by a method compaction technique. The compaction equipment shall consist of a <br />minimum ten 10 -ton (static drum weight) vibratory smooth -drum compactor. The number <br />of passes shall be subject to CERTIFYING ENGINEER's approval, at no additional cost <br />to CC &V. The method SPECIFICATIONS may be changed at any time, at the discretion <br />of CERTIFYING ENGINEER, based upon changes in material characteristics, field <br />conditions, and/or compaction equipment. <br />D. Soil Liner Fill <br />Page 8 of 14 <br />ame0 <br />Maximum rock size for rock fill shall be two- thirds of the compacted lift thickness, unless <br />otherwise approved by MANAGER, DESIGN ENGINEER, and CERTIFYING <br />ENGINEER. CONTRACTOR shall remove oversize materials from fills at no additional <br />cost to CC &V. <br />1. Soil Liner Fill shall be placed within the limits of the PSES site earthworks project as <br />shown on the DRAWINGS and shall begin only after completion of all, or MANAGER <br />and CERTIFYING ENGINEER approved portion of, excavation and Structural Fill <br />placement in the PSES site earthworks project. <br />June 19, 2012 <br />Revision 1 <br />
