Location: Cripple Creek & Victor Gold Mine Work Element: Phase 5 CQA/ VLF Project No.: 84201125EO Contractor: Ames Construction Co., Inc. Shift: Day Date: May 21, 2011 Reporting Period: 5/15/11 through 5/21/11 Days S M T WI T F S Work Shifts - D D D D D D D = Day Shift N = Night Shift Ambient Temperature Range (F): Low: 29°F to 37°F (+/-) High: 44°F to 66°F (+/-) AMEC CQA: Personnel On-site through the Reporting Period (See Attachment A). AMES: Rain and snow showers hindered work activities throughout the week. CONSTRUCTION ACTIVITIES and PROGRESS: I) EARTHWORKS A) Subgrade Preparation 1) VLF A CAT 563 vibratory smooth drum compactor was used to compact subgrade between stations J0+00 (+/-) and J7+00 (+/-). The subgrade surface was moisture conditioned (when necessary) and compacted with at least 4-passes. B) Slope Contouring 1) VLF Slope contouring performed between stations J0+00 (+/-) and J15+00 (+/-), approximately 600 feet left of centerline to 300 feet right of centerline and between stations H14+00 (+/-) and H24+00 (+/-), approximately 0 to 300 feet left and right of centerline using two CAT D-6 LGP dozers and two CAT D-8 dozers. Excess material from slope contouring was loaded into 40- ton articulating haul trucks using a CAT 950 front-end loader and was hauled to an area designated by CC&V. C) Cut to Fill 1) VLF Structural fill was placed between stations J 10+00 (+/-) and J 10+75 (+/-), approximately 200 to 250 feet left of centerline. Structural fill was placed in 18" to 24" lifts using various CAT dozes. Each lift was moisture conditioned using a tandem axle water truck (when necessary) and compacted using a 10-ton vibratory smooth drum compactor, passing over the entire fill VLF Weekly Report WE 05.21.2011
