Work activities were paused again at 10:30pm of night shift on 4/11/2012 and <br />resumed at 9:30am of day shift on 4/12/2012. This was due to a snowstorm and slick haul routes. <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) Earthworks <br />A) Topsoil <br />No work performed during the week. <br />B) Clear and Grub <br />Seedmasters were onsite to remove trees and shrubs from the remaining clear and grub areas. A <br />John Deere 240 excavator was used to clear and grub accessible areas as the fill progressed. <br />The removed trees and shrubs were hauled to the topsoil stockpile designated by CC &V in order <br />to be chipped. <br />C) Subgrade Preparation <br />Subgrade preparation was performed prior to overburden 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 CAT 773 water <br />truck. Compaction was performed using a 10 -ton vibratory smooth drum compactor passing over <br />the entire subgrade surface at least four times. The subgrade was inspected and approved by an <br />AMEC field representative, prior to fill placement. <br />In most areas, excluding flat areas where fills have started, the subgrade is keyed into as the fill <br />progresses. This is due to steep slopes that are adjacent to most fill areas. In these instances, the <br />subgrade is inspected for organics and debris by an AMEC field representative prior to fill <br />placement (keying into the subgrade). <br />MEW Weekly Report WE 04.14.2012 <br />
