' 2.0 SCOPE OF WQRK 2.1 TIME OF GRADING , This report represents geotechnical observations and testing during the construction operations from March 31, 2003 through May 9, 2003. ' 2.2 CONTRACTOR AND EQUIPMENT The grading operations were performed by Lackey Grading, Inc. through the use of one , (1) CAT D8 dozer, one (1) CAT D6 dozer, one (1) CAT D4 dozer, one (1) CAT 963 track loader, one (1) CAT 950 front end loader, one (1) motor grader, four (4) to eight (8) belly ' dump trucks, and two (2) water trucks. 2.3 GRADING OPERATIONS , Grading within the subject site consisted of an overexcavation and replacement operation, as well as an import fill operation. Grasses and weeds were removed prior to fill ' placement. Fill material was generated from off-site sources and used to bring the building pad portions of the site to finish grade elevation. Removal of afluvium, slopewash, etc., ' was performed in the driveway areas to a minimum depth of 2-feet below finish grade elevation. Overexcavated earth material was stockpiled and later used as fill. Bottoms ' were observed, probed and found to be into competent al~uvial soil by a representative of this firm. The alluvial soil is considered competent based on the removals extending to the ' elevations recommended in the Referenced No. 1 Geotechnical Study. To mitigate for potentially hydrocollapsible ailuvium and potential hazards associated with liquefaction, ' overexcavation was performed throughout the building pads, including the detached garage structures, to a minimum depth of 6-feet below finish grade elevation and to a ' minimum distance of 10-feet outside the proposed structure. The exposed bottoms were ~ ' EaGEN Corporation ~ ' A~rmed Housing Partners - Temecula, LLC Project Number: T2507-C May 2003 Page 3 ' scarified and moisture conditioned to a depth of 12-inches then compacted to 90 percent. Fill was placed in lens thicknesses of 6 to 8-inches, thoroughly moisture conditioned to ' near optimum moisture content, then compacted to a minimum of 90 percent relative compaction. Moisture conditioning of the on-site soils was performed during the compaction process through the use of a water truck. ' The pad areas were generally graded to the elevations noted on the Grading Plan. , However, the actual pad iocations, dimensions, elevations, slope locations and inclinations, etc. were surveyed and staked by others and should be verified by the Project Civil ' Engineer. 3.0 TESrtNG ' 3.1 FIELD TESTING PROCEDURES Field in-place density and moisture content testing were performed in general accordance ' with ASTM D 2922-96 and ASTM D 3017-96 procedures for determining in-place density and moisture content, respectively, using nuclear gauge equipment. Relative compaction ' test results were within the 90 percent required for all material tested, which is an indication that the remainder of the fiil placed has been properiy compacted. Test results are presented in the Appendix of this report. Fill depths and test locations were determined ' from review of the referenced grading plans. ~ 3.2 LABORATORY TESTING The following laboratory tests were performed as part of our services during the grading of , the subject site. The test results are presented in the Appendix of this report. 3.2.1 MOISTURE-DENSITY RELATIONSHIP TEST ' Maximum dry density - optimum moisture content relationship tests were conducted on samples of the materials used as fiil. The tests were performed in general accordance with ' ASTM D 1557-00 procedures. The test results are presented in the Appendix (Summary of Optimum Moisture ContenVMaximum Dry Density Relationship Test Results). ' 3.2.2 EXPANSION INDEX TEST Three (3) soil samples were obtained for expansion potential testing from the building pad ' areas upon completion of rough grading of the subject site. The expansion tests were performed in accordance with ASTM D 4829-95. The materials tested consisted of brown ' siity sands, which have Expansion Indexes of 1 through 13. These soils are classified as ~ , EnGEN Corporation ' ~ Affirmed Housing Partners - Temecula, LLC Project Number. T2507-C ' May 2003 Page 4 ' having a very low expansion potential: The results are presented in the Appendix (Summary of Expansion Index Test Results). ' 3.2.3 SOLUBLE SULFATE TEST Based on this firm's familiarity with the soils used to construct the building pad, it is our ' opinion that soluble sulfates are not a concern, and as a result, normal Type II cement can be used on concrete making contact with the native soils. ' 4.0 EARTH MATERIALS The natural and imported earth materials encountered on-site generally consisted of brown ' to dark brown silty sand. 5.Q GONCLUSIONS AND RECOMMENDATIONS ' No conditions were encountered which would cause a change in the previously provided design and construction recommendations. As a result, design and construction should ' adhere to the recommendations provided in the Referenced No. 1 Geotechnical Study. Based on the observations and tests performed during grading, the subject site, in the ' areas noted as test locations, has been completed in accordance with the Referenced No. 1 Geotechnical Study, the project plans and the Grading Code of the City of ' Temecula. The graded site, in the areas noted as graded, is determined to be adequate for the support of a typical residential development. Any subsequent grading for ' development of the subject property should be performed under engineering observation and testing performed by EnGEN Corporation. Subsequent grading includes, but is not , limited to, any additional fill placement and excavation of temporary and permanent cut and fill slopes. In addition, EnGEN Corporation should observe all foundation excavations. ' Observations should be made prior to installation of concrete forms and/or reinforcing steel so as to verify and/or modify, if necessary, the conclusions and recommendations in this ' report. Observations of overexcavation cuts, fill placement, finish grading, utility or other trench backfill, pavement subgrade and base course, retaining wall backfill; slab ' presaturation, or other earth work completed for the development of the subject site should be performed by EnGEN Corporation. If any of the observations and testing to verify site geotechnical conditions are not performed by EnGEN Corporation, liability for the safety ' and performance of the development is limited to the actual portions of the project observed and/or tested by EnGEN Corporation.
