"M It should be noted, working No.U6263 received a concrete plug and completed with an approved cemented rock fill. In addition UG working No. 6122 was completed with three layers of Geogrid. C) Highway 67 Fill continued to be hauled to the southern portion of the Highway 67 embankment using several Cat 777 haul trucks and several Cat 740 haul trucks. The Northern portion of the embankment appears to be close to fill grade. The structural fill material was placed in an approximately 18 to 24 inch lifts by Cat D10R, John Deere 1050 and Cat D8R Dozers. The Cat CS56B vibratory, 10 -ton, smooth-drum roller completed the minimum of four passes (Method Specification Applies) over each lift surface placed. It should be noted: haul trucks, loaded and unloaded, drove over the backfill surface contributing to the overall compaction of the lift. In addition a Cat 330B excavator equipped with a jackhammer (hammer hoe) broke up the oversize material encountered. A GPS dozer was observed slope contouring the western downstream slope of the embankment and is expected to continue. It) Storm Water Management Best Management Practices (BMP) are being performed. During the reporting period due to recent rains the contractor was observed clearing roadways, draining areas of standing water and cleaning out collection sumps. Erosion control efforts took place during this reporting period.
