® on site, from time of sampling through completion of testing. The QA/QC Inspector must place a sample tag on the soil sample container immediately upon sampling. The tag must remain with the soil sample throughout processing. The tag contains the following information: Sample number Material type Project name and project number Sampling inspector Date sampled Test(s) to be performed 3.2.5 Soil Sample Processing The QA/QC Inspector is responsible for the timely processing of soil test samples. The QA/QC Manager determines which samples are tested on site and which are tested off site. The determination is made based on manpower available, equipment available, complexity of test, and time available for results. For expediency, samples to be tested off site should be shipped the same day as they are obtained. 3.3 Field Density Tests 3.3.1 Test Numbering ® The QA/QC Inspector is responsible for maintaining test numbers and results for field density tests performed by the nuclear moisture density method (ASTM D2922). All other testing is identified through the sample number (Section 3.2.3). The QA/QC Inspectors will maintain field books that identify soil segments, data tested, QA/QC Inspector performing the test, and sequential test number. Each soil segment will have a unique series of numbers (i.e. general earthfill 1000 —1999, clay liner 2000-2999). No test number can be repeated for a given soil segment, and re -tests of failing tests must be given a letter suffix along with the original test number (i.e., re -tests for a failing Test #1201 would be: 1201 A, 1201B, etc.). Test data and results must be filled out on the field density test form. 3.3.2 Test Locations The intent of the CQA program is to provide confidence that the earthwork materials and work conform to the technical specifications. To meet this intent, the QA/QC Inspector will perform density tests of earthfills, clay liner, and any other soil products used during construction. Density tests must be located at various elevations and uniformly dispersed throughout the entire plan dimensions of the fill. Density test locations must be chosen without bias; however, additional testing can be performed in any areas that are suspect, marginal, or appear to be of poor quality. During the progress of the work, density test locations will be plotted on a drawing by the QA/QC Inspector to verify that no significant areas are untested. The drawing becomes part of the CQA report. Page 18
