Our analysis consisted of sampling soils after lime slurry and water pressure injection to a depth of 7 ft and performing moisture content, pocket- penetrometer and absorption swell tests on representative samples. Sampling of the injected soils using test borings was performed on November 4, 2000. A total of 18 test borings (Borings 35-52) were performed at the approximate locations shown on Figure 1, the Boring Location Plan, to obtain samples of the injected soils for laboratory testing. Individual test results are presented on summary data sheets attached to this report. According to the project geotechnical report (re: ALPHA Report No. 98611 dated August 25, 1998), acceptance of lime slun'y and water pressure injection should be based upon attaining an average free swell of 1 percent, or less, from soils within the injected zone. Results of current moisture content tests (Figure 2) indicate the average moisture content of the injected soils at each boring location varies from about 19 to 25. Results of absorption swell tests conducted on samples from the injected zone indicate free swells ranging from about 0.1 to 1.4 percent and averaging about 0.7 percent. Based on results of cur~nt moisture content tests and absorption swell tests, it is our opinion the present free swell within the injected, soils in Buildings 6, 7, 10, I 1 and G-2 conforms to the project criteria of 1 percent, or less. Therefore, it is recommended the lime slurry and water pressure injection at Buildings 6, 7, 10, 11 and G-2 be.accepted.
