CG <br />amee-, <br />The contractor placed riprap materials at the culvert outlets located on the north side of the embankment. <br />Ideal Fencing installed fencing on the west side of the Highway 67 alignment during this reporting period. . <br />South MSE Wall: <br />Ames continued mat and underdrain construction on the South MSE wall. <br />Mats were constructed by placing welded wire baskets along the exterior of the wall's alignment. The baskets were <br />wire -tied together with approximately 2.5 inches of overlap. Approximately 7ft to 8ft foot lengths of Tensar UX1500 <br />and UX1100 geogrid (per specification) were joined to the 18 inch wire welded basket leg lengths to create 8.5 to <br />9.5 foot reinforcement lengths for the wall. The Tensar geogrid was pulled taught against the wire baskets and <br />secured by hand while placing reinforcing fill material. Tensar LH800 geogrid was installed on every other mat for <br />the attachment of the timber facing. Locking tail struts were placed every 16 inches on center mechanically <br />securing the geogrid to the baskets and reinforcing the front face of the basket. A tail strut was also added at the <br />2'h inch horizontal wire overlap of the basket. Face rock was placed in the wire baskets after lining the interior front <br />face of the basket with BX1120 geogrid. Reinforcing fill material and face rock was separated from each other using <br />non -woven geotextile material. The reinforcing fill material was placed in 9 inch lifts and packed with plate tampers <br />within 3 feet of the wall face and with the CS -433 vibratory roller on the areas greater than 3 feet in distance from <br />the wall face. <br />Each mat was tested for compaction and moisture content at the completion of mat prior to placement of next mat. <br />Compaction tests performed met or exceeded 95% compaction. Reinforcing fill material was moisture conditioned <br />prior to placement. <br />Ames continued placement of the underdrain at the back of the MSE wall along the face of existing rock. Non- <br />woven geotextile was placed along a trench at the back of the wall where the reinforcing fill meets the native granite <br />wall. Four inch diameter, perforated, corrugated, HDPE piping was laid out in the trench on top of the geotextile. <br />Drain rock was placed over the pipe and wrapped with geotextiie with a minimum of 18 inch overlap prior to <br />placement of reinforcing fill. Reinforcing fill was placed in 9 inch lifts and compacted using a Cat CS433E smooth <br />drum vibratory roller. <br />Approximately, 11,758 sq. ft. of wall face has been completed to date. <br />MSE wall components continue to be installed per plans and specifications. <br />11) Storm Water Management <br />Best Management Practices (BMP) is being performed. Erosion control efforts took place during this reporting <br />period following any precipitation. <br />CQA ACTIVITIES: <br />1) Field Activities: Observation of construction activities during this reporting period included: <br />topsoil stripping /Stockpiling, production drilling and blasting, Cut to Fill ADR Haul Road (HR), HWY 67 construction, <br />PSSA Toe Berm Fill placement and compaction, MSE wall construction, Underground remediation, clay (SLF) <br />processing and Drain Cover Fill (DCF) production and processing. <br />1[) Laboratory Activities: Laboratory testing continued with Permeability, Particle Size Distribution, Atterberg Limits, <br />Moisture- Density, gradations and material classification and identifications and field material sampling were performed <br />during this reporting period. <br />SLF: Sample No. 51 was obtained during this reporting period <br />DCF: Sample No. 10 and 11 were obtained during this reporting period. <br />MLE2 WE 09.14.13.doc <br />Page 3 of 7 <br />
