Field personnel were provided for this project in orderto test and observe trench backfill operations. Our geotechnical services were performed between August 20, 1996 through February 26, 1997. Scope of Services Our observations and tests assisted us in developing professional opinions regarding whether or not the backfill operations were conducted in general accordance with the geotechnical requirements of the City of Carlsbad, as well as our geotechnical recommendations. Our services did not include supervision nor direction of the actual work of the contractor, his employees, nor agents. Our services did include the following: • Observation of trench backfill placement and compaction in order to determine whether these operations were conducted in general accordance with the geotechnical recommendations and geotechnical requirements of the City of Carlsbad. • Performing field and laboratory tests on trench backfill to support geotechnical recommendations and conclusions. 9245 Activity Rd., Ste. 103 • San Diego, Califomia 92126 Phone (858) 536-1000 • Fax (858) 536-8311 BROOKFIELD HOMES PROJECT NO. 0002-008-04 AUGUST 27, 1999 DOCUMENT NO. 9-0848 PAGE 2 Preparation of daily field reports summarizing the day's activity with regard to earthwork, and documenting hours spent in the field by our technicians. Preparation of this report summarizing backfill placement, field and laboratory test results, and the compaction operations. Fill Soils The various materials used as fill are described in Figure B-l of the appendix. The maximum densities and optimum moisture contents of the soils were determined in the laboratory in general accordance with ASTM Dl 557-91. Native soils were used to backfill the trench. The native backfill varied from sand, silty sand, and clayey sand (SP, SM and SC). Field Density Testing In-place moisture and density tests were made in general accordance with ASTM D 2922-91 and D 3017-88 (Nuclear Gauge Methods). The results of these tests are given in Appendix C, Figures C-1 through C-6. The actual test locations are shown on the Geotechnical Maps, Plates 1 through 17. The locations and elevations given for the tests are based on field survey stakes and estimates from the grading plan topography, and should be considered rough estimates. These locations and elevations should not be used for preparing cross sections showing test locations, or for after-the-fact evaluation of the sequence of fiU placement. Geotechnical Evaluation and Recommendations In our opinion, compaction of the backfill soils within the subject trenches was performed in general accordance v^th the intent of the project geotechnical recommendations, and vsdth the requirements of the City ofCarlsbad. Based upon our observations and testing, it is our professional opinion that trench backfill soils were placed in substantial accordance with the compaction criteria of 90 percent of the maximum density. The conclusions and recommendations contained herein are based on our observations and testing performed between August 20, 1996 and February 26, 1997. No representations are made as to the quality and extent of materials not observed. ———Geotechnics Incorporated BROOKFIELD HOMES AUGUST 27, 1999 PROJECT NO. 0002-008-04 DOCUMENT NO. 9-0848 PAGES 5.0 LIMITATIONS Our services were performed using the degree of care and skill ordinarily exercised, under similar circumstances, by reputable soils engineers and geologists practicing in this or similar localities. No other warranty, expressed or implied, is made as to the conclusions and professional advice included in this report. The samples taken and used for testing, the observations made, and the in-place field testing performed are believed representative of the project. However, soil and geologic conditions can vary significantly between tested or observed locations. The findings of this report are valid as of the present date. However, changes in the conditions of a property can occur with the passage of time, whether they be due to natural processes or the works of man on this or adjacent properties. In addition, changes in applicable or appropriate standards may occur, whether they result from legislation or the broadening of knowledge. Accordingly, the findings of this report may be invalidated wholly or partially by changes outside our control. Therefore, this report is subject to review and should not be relied upon after a period of three years. We appreciate this opportunity to be of professional service. Please call if you have any questions or require additional services. Sincerely, GEOTECHNICS INCORPORATED Robert A. Torres, P.E. 43077 Senior Engineer Distribution: (2) Addressee Anthony F.

The soils selected for tesfing are believed to be generally representative ofthe materials encountered during the earthwork constmcfion at the site. Laboratory testing was conducted in a manner consistent with that level of care and skill ordinarily exercised by members of the profession currently pracficing under similar condifions and in same locality. No other warranty, expressed or implied, is made as to the correctness or serviceability of the test resuhs or the conclusions derived from these tests. Where a specific laboratory test method has been referenced, such as ASTM, Caltrans, or AASHTO, the reference applies only to the specified laboratory test method and not to associated referenced test method(s) or practices, and the test method referenced has been used only as a guidance document for the general performance of the test and not as a "Test Standard." A brief descripfion of the tests perfonned follows: Classification: Soils were classified visually according to the Unified Soil Classificafion System as established by the American Society of Civil Engineers. Visual classification was supplemented by laboratory testing of selected soil samples and classification in general accordance with the laboratory soil classificafion tests oufiined in ASTM test method D 2487. Maximum Densitv Optimum Moisture: The maximum density and optimum moisture for representative soil samples were determined by using test method ASTM D1557-91, modified Proctor. The test results are summarized in Figure B-l. Geotechnics Incorporated MAXIMUM DENSITY/ OPTIMUM MOISTURE CONTENT (ASTMD1557-91) Sample No. Description Max.

For example, the American Society for Testing and Materials has recently researched the precision of ASTM Method No. Dl 557 and found the accuracy ofthe maximum dry density to be plus or minus 4 percent of the mean value and the optimum moisture content to be accurate to plus or minus 15 percent of the mean value; the Society specifically states the "acceptable range of test results expressed as a percent of mean value" is the range stated above. In effect, an indicated relafive compacfion of 90 percent has an acceptable range of 86.6 to 92.8 percent based on the maximum dry density determinafion. The precision of the field density test ASTM D1556 has not yet been determined by the American Society for Testing and Materials; however, it must be recognized that it also is subject to variations in accuracy. -The following abbreviations were used in the Figures of Appendix C: JT - Joint Trench SD - Storm Drain S - Sewer W - Water Geotechnics Incorporated Geotechnics Incorporated DENSITY TEST RESULTS Broccato Testing & Observation Project No. 0002-008-04 Document No. 9-0848 FIGURE C-1 Test Test Elevation/ Soil Max.
