This râ‚¬port presents a sunmary of our field observations, test rcsults, conclusions and recommendations based on our field inspoction, testing and a review of the referenced report and docurnents. Scope Of Service During the grading operation the pmvided services included: Earthwork Monitoring; In-place Field Density Testing; Correlative [aboratory Testing; Documentation Rough Grading earthworks started on March 28, 2019, and were accomplished on April 16,2019 in accordanc.e with our recommendations presented herewith. {r75 N.

Prge:2 Earthwork Monitorirg and Soil Compaction Test Report Proposed Residential Building 202 E Adams Ave, Senta Ata, CA 92707 LIMITATIONS: Between exploratory excavations and/or field testing locations, all subsurface deposits consequeflt of their anisotropic and heterogeneous characteristios csn and will vary in many important geotechnical properties. The results presented herein are based on the infomration in part fumished by others and as generated by this firm, and represent our best interpretation of that data benefitting from a combination of our earthwork related constuction experiencc, as well as our overall geotechnical knowledge. Hence, the conclusions and recommendations expressed herein are our professional opinions about perthent project geotechnical parameters which inlluence the understood site use; therefore, no other warranty is offered or implied. Test results are representative of compaction testing at the tested areas only. All the findings are subject to field modification as more subsurface exposures become available for evaluations. Before providing bids, contractors shall make thorough explorations and findings. Soil Pacific Inc. is not responsible for any financial gains or losses acsrued by persons/firms or third party from this project. In the case that contents ofthis report are not clearly understood, due in part to the usage oftechnica.l terms or wording please contact the undersigred in writing for clarification. Reguletory Compliance Earthwork described herein has been monitored by a representative ofthis firm. and has been found to be in compliance with applicable local gadine ordinances. The rough grading was started March 28,2019, and were accomplished on April 16,2Ol9 in accordance with our recommendations preseoted herewith. Documentstiotr This report documents findings, test results, conclusions and recommendations from soils and foundations orgineering standpoint. Prior to the start of grading on the site, deleterious materials were gn:bbed and rernoved from the site. Project No. A-645$2-19 202 E Adrms Ave., Srntr rtrl' CA 92707 Prge: 3 Site Grading and Soil Excevetion The gading was Derformed in accordance with proiect design and recommendations to rernove and recompact a minimum of 4 feet below the existing grade. Soil density test s were provided during the grading operation. On-site clayey sand materials was used to backfill. A limited of borrowed materials were used during the backfill. During the R& R operation stockpiled soils were mixed and controlled to have an optimum moisture conteDt. Field Testing Field density testing was performed to veri& the relative degree of compaction using the nuclear gauge P/BC 201l-28 deosity testing and sand cone tools. A total of 19 tests was conducted after grading. A surnmary oflaboratory and compaction test results is 8ttached herewith. The approximate locations offield density tess are shown on the Compaction Test l,ocation Plan (A-l-l). The fill is considered as primary and structural fill. Crading equipments were used to overexcavate the Droposed buildins area and 5 feet beyond wherever was applicable. The bottom ofthe proposed pad was scarified to a minimum of8 inches. The soil compaction tests indicated that tested fill materials where tested exhibiting more than 90olo relative compaction and therefore are competent. Lrboretory Testing The laboratory maximum dry density and optimum moishre content of each major soil encountcred during grading were daermined in accordance with ASTM Method D-I557-00 results are shown in Table l. t,?e The Table I MAXIMUM DRY DENSITY OPTIMUM MOISTURE Soil Description Cuwe Letter Maxrmum dry dens.Optrmum moishre Sandy clay A 114 17.4 Verification Based on our field and laboratory testing, the building pad and the area compacted during the rough grading appear uniformly compacted, exhibiting at least 90 percent relative compaction. On the basis of the forgoing information together with data supplied in the referencâ‚¬d repon, it is the opinion of this firm, that the observed soils have been properly compacted and are mnsidered adequate to be capable of supporting the planned improvements.
