A. Perform all earthwork to the lines and grades as shown on the Construction <br /> Drawings and/or established by the DESIGN ENGINEER. Shape, trim, and finish <br /> slopes of channels to conform with the lines, grades, and cross sections shown. <br /> Make slopes free of all exposed roots and stones exceeding 3-inch diameter that <br /> are loose and liable to fall. Round tops of banks to circular curves, in general, not <br /> less than a 6-foot radius. Rounded surfaces shall be neatly and smoothly trimmed. <br /> Neatly blend all new grading into surrounding, existing terrain, and maintain <br /> current drainage patterns or modify drainage as shown on the Construction <br /> Drawings. Overexcavating and backfilling to the proper grade will not be <br /> acceptable. Finished site grading will be reviewed by the QA/QC <br /> CONSULTANT. <br /> 3.22 TOLERANCES <br /> A. Construct material limits within tolerance specified in Section 01410, SURVEYS. <br /> 3.23 TOPOGRAPHIC SURVEYS <br /> A. Refer to Section 01410, SURVEYS, for requirements regarding preconstruction <br /> surveys. <br /> B. The OWNER will conduct detailed topographic surveys of site to document "as- <br /> built" prepared subgrade on base and slope, thickness and grade of clay liner <br /> installed, thickness of granular drainage layer installed, thickness of protective <br /> operations layer installed, dimensions of termination berms and sumps, <br /> terminations of geomembrane liner, and location of the interior crest of anchor <br /> trenches. All surveys will be performed in accordance with Section 01410, <br /> SURVEYS. <br /> 1. Measure area elevations on minimum 75-foot-grid over entire area and at all <br /> breaks in grade. <br /> 2. Establish reference grid at minimum 75-foot centers for surveying materials <br /> with a thickness requirement. <br /> 3. Measure linear dimensions a minimum of 75-feet on center. <br /> 4. Plot results of topographic surveys to scale of 1 inch equals 50 feet and <br /> provide survey information in electronic format to QA/QC CONSULTANT. <br /> 5. QA/QC CONSULTANT will check the survey. The EARTHWORK <br /> CONTRACTOR shall not construct next layer of the lining system until <br /> survey approval is provided by the QA/QCCONSULTANT. QA/QC <br /> CONSULTANT's review shall be completed within 2 working days <br /> following receipt of the as-built survey information. <br /> 3.24 ACCEPTANCE OF WORK <br /> A. Final acceptance will be based on tests made on completed Work, on samples of <br /> ® material taken from the completed layers, and the as-built surveys. Testing for <br /> final acceptance will be performed by the QA/QC CONSULTANT in accordance <br /> with the requirements of these Specifications and the CQA Manual. <br /> Forward Landfill WMU FU-13 <br /> 02300 27 EARTHWORK <br />
