Cripple Creek&Victor Gold Mining Company <br /> Squaw Gulch VLF Phase 1 (9.450 foot to 9.550 foot bench) amec <br /> Final Report Addendum foster <br /> Quality Assurance Monitoring &Test Results wheeler <br /> December 1 2015 <br /> 7.0 Project Deviations <br /> 7.1 Drawing Deviations <br /> During construction several adjustments were made in the field to fit actual site <br /> conditions during construction. A list of those changes are discussed below. <br /> • Localized changes in grading occurred throughout the project during construction. <br /> These slight deviations have been recorded in the ROC drawings in Appendix A. <br /> These changes occurred to adjust to actual field conditions to better accommodate <br /> the design intent. <br /> • Localized changes in underdrain and HVSCS pipe alignments occurred throughout <br /> the project during construction. These slight deviations have been recorded in the <br /> ROC drawings in Appendix A. These changes occurred to adjust to actual field <br /> conditions to better accommodate the design intent. <br /> • Details 2 and 3 on IFC Drawing A220 indicate a fusion weld between the phased <br /> liner connections. An extrusion weld was used instead and is acceptable. <br /> • On ROC Drawing 3 in Appendix A, there are three locations shown referred to as <br /> blanket drains, a profile and section of these drawings is shown in the figure below. <br /> The blanket drains were used to capture several natural ground water springs in <br /> close proximity to one another and direct the water to the tertiary underdrain piping <br /> system. <br /> • A short portion of the SLF containment berm (not the pad) on the southwest limits <br /> was constructed at a slope slightly steeper than 2HAV; ore will remain a minimum <br /> of 20 feet from the berm as outlined in the design. The entire berm is covered with <br /> geomembrane liner to protect it from erosion. <br /> 30 <br />
