The stockpiles were loaded into 40 -ton articulating <br />haul trucks using a CAT 385 excavator, a John Deere 850 excavator. The topsoil was placed in a <br />stockpile area designated by CC &V. The stockpile area was maintained using various CAT <br />dozers and a CAT 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 removing trees and shrubs from the area. These trees and <br />shrubs will be hauled to a chipping area designated by CC &V and are be chipped and mixed into <br />the 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 02.04.2012 <br />
