Final Report
Quality Assurance Monitoring & Test Results
January 2016
Project No.: 74201125N0 Page 14
4.0 EARTHWORK CQA TESTING AND MONITORING
The following sections summarize results of the earthwork CQA testing and monitoring
performed by Amec Foster Wheeler.
Amec Foster Wheeler performed CQA testing of in-place materials used for construction
of the Project. Table 4 presents specified and observed CQA testing frequencies.
Figure 2 shows the construction and geomembrane installation limits and coordinate
system used to locate tests.
In accordance with the AMEC Earthworks CQA Plan (Section 1400.1 of the project
technical specifications in Appendix E), when an Amec Foster Wheeler monitor
observed deficiencies, the monitor determined the nature and extent of the problem and
notified Ames and/or CC&V. Amec Foster Wheeler then performed additional testing to
define the extent of the deficient area. Ames corrected deficiencies to meet the
requirements of the project technical specifications and Amec Foster Wheeler re-tested
the corrected area(s) prior to any additional related work. The following sections include
discussions of results encountered.
Discussions in Section 4.0 and subsequent subsections represent testing within the
Project boundary unless otherwise noted.
4.1 Results of Laboratory Soils Testing
Amec Foster Wheeler performed laboratory testing of soils during all earthworks aspects
of the construction at Amec Foster Wheeler’s on-site soils laboratory. To verify that the
earthwork materials used during construction met project technical specifications, Amec
Foster Wheeler performed the following tests in accordance with the American Society
for Testing and Materials (ASTM):
• Grain size distribution (ASTM D1140 for material finer than the No. 200 sieve, and
ASTM C117 and C136 for coarse material)
• Moisture content (ASTM D2216)
• Atterberg limits (ASTM D4318)
• Standard Proctor compaction (ASTM D698)
• Permeability (ASTM D5084, Method D)
• In-place density testing (ASTM D6938)
• Soil description (ASTM D2488)
The laboratory test results are summarized in Tables 5 through 10 and individual
laboratory test results are presented in Appendix H.
