Post Office Box 746 Clements, CA 95227-0746 Subject: FIELD DENSITY TESTS KRC AGGREGATE BUILDING PAD LOCKEFORD, CALIFORNIA INTRODUCTION This report presents the results of compaction tests taken at the subject project. At your request, Messrs. Hal Cochran and Vern Selvage of-our firm performed tests at the site on August 19 and September 16, 1992, on an intermittent basis. According to our test records, the test results conform to the compaction requirements of the project specifications. The test results were given to your representative on the testing;dates and are shown on Table I. WORK AT THE PROJECT SITE Eight tests were taken by the nuclear probe test method at random locations on a building pad. The depth of fill was approximately 1.5 to 2.5 feet. t r LABORATORY TESTING Samples of the material tested were returned to the laboratory for determination of the maximum density-optimum moisture content. The laboratory test results are shown on Table TF LIMITATIONS Because Kleinfelder, Inc. was not involved in the original geotechnical study and did not observe the grading for the project, we cannot accept any responsibility for the quality of construction or the adequacy of design. This includes, but is not limited to, settlement of existing fill. The scope of our work was strictly limited to density testing in the areas noted. .i We have employed accepted engineering and testing procedures. However, we do not: ndertake the guarantee of construction, nor do we relieve the contractor of his primary responsibility to produce a completed project conforming to project plans and specifications. i 9 Copyright 1992 Kteinfet&r, Inc.
