07-2250 (CSCS) Report of Observation and Testing During Rough GradingA y R Sladden Engineering 6782 Stanton Ave., Suite A, Buena Park, CA 90621 (714) 523-M2 Fax (714) 523-1369 39-725 Garand Ln., Suite G, Palm Desert, CA 92211 (760) 772-3893 Fax (760) 772-3895 November 1, 2006 Equity Directions, Inc. 77-564 Country Club Drive, Suite 100 Palm Desert, California, 92211 Project: Center Pointe Development SEC Washington Street &c Miles Avenue La Quinta, California Subject: Report of Observations and Testing During Rough Grading Project No. 522-3598 06-07-755 CITY OF LA QUINTA BUILDING & SAFETY DEPT. APPROVED BY. Ref: Geotechnical Investigation report prepared by Sladden Engineering dated January 16, 2004, Project No. 544-3598, Report No. 04-01-056 Summarized in this report are the results of in-place density tests performed at the subject site during rough grading along with pertinent observations. The project- site is located on the southeast comer of Washington Street and Miles Avenue in the City of La Quinta, California_. The project includes a hotel complex. -" The building pad areas were overexcavated to a depth of approximately 3 feet below existing grade or 4 feet below pad grade, whichever was deeper. The previously removed soils, native soils obtained from the cut areas of the=project site and import soils were placed in thin lifts at near optimum moisture content and compacted to at least 90 percent relative compaction. The rough grading was performed as recommended in the above referenced Geotechnical Investigation report. Observations and field testing was performed from January 20, 2005 through August 12, 2005. Testing indicates that a minimum of 90 percent relative compaction was attained in the areas tested. The passing test results indicate compliance with the project specifications at the tested .locations and depths but are no guarantee or warranty of the contractors work. Field Tests: In-place moisture/density tests were performed using a nuclear density gauge in accordance with test methods ASTM D 2922 and ASTM D 3017. A total of 143 density tests were performed. The test results are summarised on the attached data sheets. Laboratory Tests: The moisture -density relationships for the tested materials were determined in the laboratory in accordance with test method ASTM D 1557-91, 1 M C M � T �[ AUG 0 7 2007 November 1, 2006 -2- Project No. 522.3598 06-07-7,55 Allowable Bearing Pressures: Footings should extend at least 12 inches beneath lowest adjacent grade. Isolated square or rectangular footings, at, least 2 feet square and continuous footings should be at least 12 inches wide. Continuous footings may bee designed using an allowable bearing value of 1500 pounds per square foot and isolated pad footings may be designed using an allowable bearing pressure of 1.800 psf, The allowable bearing pressures are for dead and frequently applied live loads and may be increased by 1/3 to resist wind, seismic or other transient loading. The bearing soils are non -expansive and fall within the "very low" expansion category_ in accordance with Uniform Building Code (UBC) classification criteria.
