3, <br />6. Liner Compaction & Moisture Testing <br />Compaction and moisture content of each lift shall be verified by the use of a nuclear moisture - density meter or <br />by other methods approved by the Engineer. Obtaining consistent and correct moisture levels in the liner is very <br />important. The nuclear meter shall be calibrated prior to collecting compaction and moisture readings. <br />Compaction and moisture readings shall be collected simultaneously. <br />All compaction and moisture readings taken shall be recorded and documented as described above. Any readings <br />which fall outside the allowable tolerances shall also be documented. When the desired water content or <br />compaction of the compacted fill is not being met, the Contractor shall be notified immediately in order to correct <br />the problem. <br />All compaction and moisture readings taken shall be recorded and properly documented. Minimum information <br />required for documentation shall include: <br />a) project name <br />b) date <br />c) test method used (i.e. ASTM specification) <br />d) site name <br />e) technician name <br />f) location of reading (include sketch, if necessary) <br />g) percent of compaction <br />lh) wet density, pcf <br />i) dry density, pcf <br />D moisture content, percent <br />k) lift number <br />1) minimum compaction required <br />in) acceptable moisture tolerance <br />n) soils lab name, report number and proctor test results used to obtain field measurements <br />7. Liner Thickness & Permeability <br />The Geotechnician shall make note during the testing of the final lift the total constructed liner thickness. Liner <br />thickness measurements shall be performed on each sidewall of the reservoir as well as the floor. A minimum of <br />two (2) thickness measurements per sidewall and nine (9) thickness measurements in the floor shall be made by <br />the Geotechnician. The Geotechnician present will notify the Contractor of any deficiencies in the liner thickness <br />and the Contractor will make all necessary reparations to correct those areas. The minimum acceptable liner <br />thickness is twenty -four inches on the reservoir bottom and eighteen inches of each reservoir sidewall (as <br />indicated on the Earthwork Construction Plans). All thickness measurement shall be included in the <br />Geotechnician's final report. <br />Once the compacted liner has been constructed, the Engineer shall make a final inspection of the reservoir liner. <br />A minimum of one core sample per acre of the reservoir (two per sidewall, nine in the reservoir floor) will be <br />collected from the installed liner and each will be analyzed for permeability via a flexible wall permeameter. The <br />maximum acceptable seepage rate is 1.0 x 10 " cm/sec when applied with the constructed liner thickness, liner <br />permeability results and maximum constructed water depth. <br />SECTION 3100 00 - 5 <br />
