1 ' September 28, 1998 If the embankment is 'over built', the engineer should be notified for clarification. ' 3.5 COMPACTION EQUIPMENT A. General The Contractor shall provide sufficient compaction equipment of the types and sizes ' suitable as is necessary for compaction of the various fill materials. The Contractor's procedures for compaction of fill shall be subject to the approval of the Engineer. Compaction of each layer of fill shall proceed in a systematic, orderly and continuous manner approved by the Engineer, such as to ensure that all of each layer receives the compaction specified. The compaction shall be ' carried out by routing the compaction equipment parallel to the axis of the embankment or fill, except that where such routing is impractical such as in roller turning areas, in areas adjacent to foundations or at the lower elevations of the fill, in areas adjacent to pipework and where otherwise required by the Engineer, the ' compaction equipment may be routed in any direction approved by the Engineer. Special attention shall be paid to the soil synthetic liner interface. Compaction will t be achieved using the following compaction techniques in the soil synthetic liner interface area without causing damage to the synthetic liner. ' D. Special Compactors Special compactors shall be used to compact materials which, in the opinion of the Engineer, cannot be compacted properly by the Specified sheepsfoot or vibratory rollers because of location or accessibility. The Contractor shall adopt special compaction measures such as hand-held vibratory compactors or other methods approved by the Engineer to compact fill in trenches, around structures and in other confined areas which are not accessible to the larger vibratory roller or sheepsfoot roller type compactors. Such compaction ' shall consist of not less than 4 coverages of the compaction equipment ' 3.6 QUALITY CONTROL The Engineer will conduct field tests and the related laboratory tests to determine the percent compaction and other properties. The Contractor shall give the Engineer full cooperation in sample taking or making tests and shall render such assistance as is necessary to enable sampling and testing to be carried out expeditiously. The Contractor shall allow sufficient time for the Engineer to perform the required test work in order to determine the acceptability of each lift. The making of such tests or the time ' J:\5x81\$PECSFNL WPD Earthwork 02200-10
