Work activities were not performed for the remainder of the <br />week. <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) EARTHWORKS <br />A) Subgrade Preparation <br />1) VLF <br />A CAT 563 vibratory smooth drum compactor was used to compact subgrade between stations <br />J7+00 (+/-) and J13+00 (+/-). The subgrade surface was moisture conditioned (when <br />necessary) and compacted with at least 4-passes. <br />Subgrade preparation was performed between stations J 10+00 (+/-) and J10+75 (+/-), <br />approximately 200 to 250 feet left of centerline. A CAT D-8 dozer was used to rip the <br />subgrade surface to a depth of 6" to 8". The subgrade was then moisture conditioned using a <br />CAT 773 water tuck (when necessary) and compacted using a 10-ton vibratory smooth drum <br />compactor. The entire surface of the subgrade was compacted with at least 4-passes. This area <br />was inspected by an AMEC representative and accepted for structural fill placement. Soil <br />temperatures were monitored prior to structural placement and found to be acceptable. <br />B) Slope Contouring <br />1) VLF <br />Slope contouring performed between stations J0+00 (+/-) and J24+00 (+/-), approximately 600 <br />feet left of centerline to 300 feet right of centerline and between stations H8+00 (+/-) and <br />VLF Weekly Report WE 05.14.2011
