Newmont-Cripple Creek & Victor Gold Mine <br />Technical Specification No. 02200-1 EARTHWORKS – Owner Performed Work <br />VLF2 Phase 3 <br />Project No.475.0106.049 <br />September 13, 2023 <br /> <br /> <br /> <br />Technical Specification No.02200-1 Earthworks – Owner Performed Work Page 3 <br />Acceptance of non-conforming materials: In cases where non-conformance to these material <br />specifications occur the Design Engineer in tandem with the Manager can approve the material <br />for use, if in their opinion, the specification deviation does not diminish functionality of a given <br />design element and/or compromise the design intent. If non-conforming materials are accepted <br />by the Design Engineer and Manager for use during construction, the DRMS will be contacted, <br />within a week of discovery, to alert them to the acceptance and rationale behind acceptance of <br />non-conforming materials. <br />3. PART 3: EXECUTION <br />3.1. Waste Removal <br />Waste material is defined as material too wet, too dry, frozen or containing ice or snow, <br />containing organic or other deleterious matter, having poor characteristics of grading or <br />compaction, having other characteristics that may result in undesirable settlement or other <br />movement of the fill, or within the fill, or otherwise not meeting the requirements of the <br />SPECIFICATIONS, provided that this definition permits drying, water, and any other processing or <br />reprocessing to make the material stable and suitable prior to incorporating it into the fill as <br />permitted in the SPECIFICATIONS or by the MANAGER and CERTIFYING ENGINEER. <br />A. CONTRACTOR shall excavate and remove waste in a manner that will minimize <br />contamination with other soil horizons. <br />B. CONTRACTOR shall stockpile removed waste at locations designated by MANAGER <br />3.2. Excavation <br />A. CONTRACTOR shall perform excavation to the lines and grades shown on the DRAWINGS <br />or as directed by MANAGER. No excavation shall begin until the CONTRACTOR has <br />provided construction staking for the proposed work. <br />B. CONTRACTOR shall prevent the disturbance of surrounding areas during excavation. <br />Where selective excavations are required to obtain materials for Structural Fill, the <br />material removed from the excavations shall be taken directly to the fill areas or, if <br />required, stockpiled by material types. The stockpiles shall be approved by MANAGER. <br />C. CONTRACTOR shall grade all excavations to ensure grades are maintained to provide <br />adequate drainage at all times. Work shall be suspended by CONTRACTOR when, in the <br />opinion of MANAGER and CERTIFYING ENGINEER, the site is overly wet, muddy, or <br />otherwise unsuitable for proper maintenance, until directed otherwise by MANAGER, at <br />no cost to CC&V. <br />D. In excavations where Structural Fill is to be placed on slopes steeper than 3H:1V, <br />horizontal benches shall be excavated into the slope to allow fill to be placed in
