_ o LW <br />MILL SITE EARTHWORKS FIELD MONITORING SUMMARY (WEEKLY REPORT) <br />Project Title: Mill Site Earthworks <br />Owner: Cripple Creek & Victor Gold Mining Co. <br />Location: Cripple Creek & Victor Gold Mine <br />Work Element: Mill Site Earthworks <br />Date: January 14, 2012 <br />Reporting Period: 1/812012 through 1/14/2012 <br />Days <br />S <br />I M <br />T <br />I W <br />I T <br />F <br />S <br />Work Shifts <br />D <br />DID <br />D <br />D <br />F- <br />F <br />N <br />N <br />N <br />N <br />- <br />D = Day Shift <br />N = <br />Night Shift <br />Project No.: 84201125K0 <br />Contractor: Ames Construction Co., Inc. <br />Shift: Day /Night <br />Ambient Temperature Range (F): Low: 0 °F to 22 °F ( + / -) High: 41 OF to 50 °F <br />AMEC CQA: Personnel On -site through the Reporting Period (See Attachment A). <br />Ames: None <br />CONSTRUCTION ACTIVITIES and PROGRESS: <br />I) Earthworks <br />A) Topsoil Stripping <br />Topsoil stripping within the Mill Site Earthworks project was performed using various CAT dozers <br />pushing the material into temporary stockpiles. The temporary stockpiles will be hauled to a <br />stockpile designated by CC &V at a later date. <br />B) Clear and Grub <br />Clear and grub activities were performed by Seedmasters for the Mill Site Earthworks project. A <br />Hitachi 160 excavator, a John Deere 135 excavator, and a CAT D -6 dozer were used to removing <br />trees and shrubs from the area. These trees and shrubs will be hauled to the topsoil stockpile <br />area designated by CC &V and will be chipped and mixed into the topsoil as it is placed. <br />C) 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 />In most areas, excluding flat areas were fills are started, the subgrade is keyed into as the fill <br />progress. This is due to steep slopes that are adjacent to most fill areas. In this instance, 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 01.14.2012 <br />
