The Record Drawings shall include elevations and locations for the <br />following: <br /> <br /> Underdrain plan view showing the limits of the valley leach facility. Underdrain Fill <br />and underdrain alignment, with elevations every approximately 100 feet or on every <br />break in grade <br /> Diversion channel plan and profile view along the diversion channel alignment <br /> Leak detection trench plan view showing the limits of the valley leach facility, leak <br />detection trench alignment, and leak detection sumps, with elevations every <br />approximately 100-feet <br /> Soil Liner Fill plan view showing the limits of the valley leach facility, with <br />contours of the Soil Liner Fill and Bedding Fill surface on a 10-foot contour interval, <br />including the regraded ore slopes and end berms <br /> Low Volume Solution Collection piping plan showing the limits of the composite <br />liner, double liner and single liner, and piping alignment with elevations every <br />approximately 100 feet <br /> Perimeter access roads <br /> Top of Upper geosynthetics in the Pregnant Solution Storage Area, including the <br />Vertical Riser Sump and base plates <br /> High Volume Solution Collection piping plan showing the limits of the VLF, and <br />piping alignment with elevation every approximately 100-feet <br /> <br /> In addition, the Colorado licensed surveyor will provide a surveyor's certificate to be submitted in the <br />Construction Certification Report. <br /> <br /> C. Submittal: <br /> <br /> CONTRACTOR will submit completed as-built documentation within seven (7) calendar days upon <br />completion of the work in the following manner: <br /> <br /> 1. Submit two (2) hard copies to the MANAGER. <br /> <br /> 2. Submit two (2) non-reproducible copies to the MANAGER in electronic form on <br />compact disks (CD) or DVD’s and in an AutoCAD compatible format. <br /> D. The CONTRACTOR will be responsible for performing the following survey activities associated <br />with the Construction Certification Report: <br /> <br /> 1. Provide northing, easting, and elevation for all Soil Liner Fill depth verifications. <br /> <br /> 2. Provide northing, easting, and elevation for geomembrane panel intersections and <br />destructive samples. <br />
