APPENDIX D - LABORATORY TESTING

DY-GP-KL selected samples from the borings to be tested and the tests to be performed on the selected Integrated Fixed Tower (IFT) samples. The scope of services did not include laboratory testing on soil samples obtained from the test pits. Laboratory testing was performed by Kleinfelder. A summary of the laboratory tests performed are presented in Table D1.

Laboratory data are categorized by IFT site as summarized in Table D2. Because of sample disturbance, dry density tests could not be performed on many samples.
