Night shift activities were not performed Saturday (2/18/2012). <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) Earthworks <br />A) Topsoil Stripping <br />Topsoil stripping and re- location was performed within the Mill Site footprint using various CAT <br />dozers pushing the material into stockpiles. The stockpiles were loaded into CAT 40 -ton <br />articulating haul trucks using a CAT 385 excavator, a John Deere 850 excavator, a CAT 992 <br />front -end loader, and a CAT 988 front -end loader. The topsoil was placed in a stockpile area <br />designated by CC &V. The stockpile area was maintained using various CAT dozers and a CAT <br />motor - grader. <br />B) Clear and Grub <br />Clear and grub activities were performed by Seedmasters for the Mill Site Earthworks project. A <br />John Deere 135 excavator, a Volvo 160 excavator, a John Deere 850 dozer, a CAT D -6 dozer, <br />and a skid steer loader were used to remove trees and shrubs from the area. These trees and <br />shrubs will be hauled to a chipping area designated by CC &V and are chipped and mixed into the <br />topsoil as it is placed. <br />Q Subgrade Preparation <br />Subgrade preparation was performed prior to structural fill placement in the areas shown on <br />Figure 1. Various CAT dozers were used to rip the existing surface to a depth of at least 6 inches. <br />Moisture conditioning of the subgrade was performed (when necessary) using a tandem axle <br />water truck. Compaction was performed using a 10 -ton vibratory smooth drum compactor passing <br />over the entire subgrade surface at least four times. The subgrade was inspected and approved <br />by an AMEC field representative, prior to fill placement. <br />MEW Weekly Report WE 02.18.2012 <br />
