Magna Vista Ave., Arcadia, California Subject: Soils Compaction Report for Swimming Pool Backfill 222 E. Magna Vista Ave., Arcadia, California GYGC Project No.: GYGC-20-002 Gentlemen: This report presents a summary of geotechnical engineering testing services provided by G.Y. Geotech Consulting (GYGC) during the earthwork construction phase of the subject site. PURPOSE OF FILL The purpose of the earthwork was to Backfill of the Existing Swimming Pool at subject site. Based on our field density testing and the laboratory testing results, it is our opinion that the fill placed within the subject site can be classified as a non-structural fill and is expected to provide adequate support for the anticipated development. SUMMARY OF ROUGH GRADING EARTHWORK Grading operations at the proposed area were performed during February 24 2020 to March 5 2020. The fill placed is considered adequate for the anticipated development and usage. No adverse geotechnical conditions are known to exist that would preclude for the anticipated development and usage. A backhole and bobcat were used to the grading operation, import olive clayey sand (SC, Soil Type A) and olive silty sand with gravel (SM, Soil Type B) were used as fill are considered adequate for the anticipated development and usage. Two holes (20"x20") were cut at the bottom of old swimming pool. The competent soils were exposed. The top one foot concrete were shattered and taken away from the North, East and West sides of old swimming pool. All grading at the project site were completed and complies with Arcadia City Buildings and Constructions Regulations and LA County. Specific grading operations performed for the subject site included the following: Fill Placement 1. Bottom inspection was performed, two holes (20"x20") were cut at the bottom of old swimming pool. The competent soils were exposed. 2. The top one foot concrete were shattered and taken away from the North, East and-West side of old swimming pool. 3. Fill of import olive clayey sand (SC, Soil Type A) and olive silty sand with gravel (SM, Soil Type B) were placed in relatively thin lifts (8 inches), brought to near optimum moisture content, and then compacted. 4. The approximate maximum depth of fill placed within the retaining wall and swimming pool areas under the purview of this report is about 8.5 feet. FIELD DENSITY TEST 1. Field density test was performed using the Sand Cone Method (ASTM D-1556-09). The field density test results are presented in Table 2. Approximate locations of the test are shown on the enclosed Site Plan (Figure 1 ) 2. Field density tests were performed at random locations to check compaction effort provided by the contractor. The test results exceeded minimum required relative compaction of 90 percent. The test results herein are considered representative of the compacted area. 3. The fill of import olive clayey sand (SC, Soil Type A) and olive silty sand with gravel (SM, Soil Type B)were verified to match with the laboratory tested samples. 4. The compacted fill is considered adequate for its intended use. LABORATORY TESTING The laboratory maximum dry density and optimum moisture content for the onsite soils were determined according to laboratory standard ASTM D-1557-09. The following table presents the test result of representative soil samples. TABLE 1 LABORATORY TEST RESULTS 1. Maximum dry density and optimum moisture content Soil Type Maximum Dry Density Optimum Moisture (pcf) Content(%) Olive clayey sand (SC, Soil Type A)/ 128.5 9.5 Import Olive silty sand with gravel (SM, Soil Type B)/ Import 133.0 8.0 2. Corrosion'Potential Chemical laboratory tests were recommended on the filled soils to aid in evaluation of soils corrosion potential and the attack on concrete by sulfate soils. 3. Expansion Potential Due to the filled soils were clayey sand and silty sand, Expansion potential is expected to be low. However, expansion index laboratory tests were recommended to aid in evaluation expansion potential. POST-GRADING RECOMMENDATION 1. All utility backfill should be brought to near optimum moisture content and then compacted to obtain a minimum relative compaction of 90 percent of the laboratory standard. 2. All trench excavations should conform to CAL-OSHA and local safety codes. 111 STATEMENT Based on our field density testing results and grading observation, it is our opinion that the completed grading will be safe against hazard from landslide, settlement, or slippage and the completed grading will have no adverse affect on the adjacent properties. FILL CONDITION Based on our field and laboratory test results, it is our opinion that the fill placed within the swimming pool can be classified as primary structural fill and,are considered adequate to provide the support for the proposed development. REGULATORY COMPLIANCE This report presents information and data relative to the grading and placement of compacted fill at the subject site. Representative(s) of this firm conducted periodic tests during the progress of the compaction in an effort to determine whether compliance with the City of Arcadia's grading specifications was being obtained. The presence of our personnel during the work progress did not involve any direct supervision of the contractor or his work forces and does not relieve the contractor of the primary responsibility to perform all work in accordance with the project specifications and the City's Buildings and Constructions Regulations. Completed work under the purview of this report is considered suitable and adequate for the intended use from a geotechnical point of view. This opportunity to be of service is appreciated.
