9607-047 (CSCS) Report of Testing & ObservationsREPORT OF TESTING & OBSERVATIONS DURING GRADING 111 LA QUINTA CENTER LA QUINTA, CALIFORNIA PREPARED FOR TRANSPACIFIC DEVELOPMENT COMPANY B7 -2083-P3 JUNE 18, 1992 d EARTH SYSTEMS CONSULTANTS Earth Systems Consultants WSouthern California June 18, 1992 Transpacific Development Company 2377 Crenshaw Boulevard Torrance, California 90501-3325 Project: 111 La Quinta Center La Quinta, California Buena Engineers Division 79-811 B Country Club Drive Bermuda Dunes, CA 92201 (619) 345-1588 (619) 328-9131 FAX (619) 345-7315 B7 -2083-P3 92-06-727 Subject: Report of Testing and Observations Performed During Grading Ref: Geotechnical Engineering Report by Buena Engineers, Inc. dated January 17, 1990; Report No. 90-01-788 Interim Report of Testing & Observations during Grading by Earth Systems Consultants dated April 13, 1992; Report No. 92-04-737 Submitted herewith is a report of testing and observations performed during the rough grading on the above referenced project. Grading operations were performed by James Rue Construction using conventional heavy equipment. Testing was performed as per authorization of Colm Macken. Test results are presented on the attached test report sheet with their estimated locations plotted on the accompanying. plan. Compaction tests were performed. in accordance with ASTM D 2922-81 Method A or B and ASTM D 3017- 88 Nuclear Density Test Procedures. Maximum Density -Optimum Moisture were determined in the laboratory in accordance with ASTM D 1557-78, Method A Test results are as follows: Soil Description USSCS Maximum Density -Optimum Moisture Grey brown very fine to fine sand S P 106.3 pcf 14.4° Brown slightly clayey silty very fine to fine sand SM 115.7 pcf 11.7% Brown clayey very silty very fine sand SM 118.8 pcf 11.90/0 June 18,1992 -2- B7 -2083-P3 92-06-727 DISCUSSION: I. The project is located on the north side of Highway 111 between Adams Street and Washington Street in the City of La Quinta, California. 2. Prior to grading, the site consisted of vacant land with scattered desert brush, short grass, weeds and debris. A building was removed prior to grading. 3. The proposed development will include a large commercial complex. 4. The scope of our work was based on plans and staking by Hall and Foreman. 5. The project area was cleared of vegetation and debris prior to the start of grading operations. 6. Building areas adjacent to the Whitewater channel were excavated to depth of approximately ten (10) feet below pad grade. An additional twelve (12) inches were scarified, moisture conditioned and compacted. 7. The remaining building areas were excavated to a depth of five (5) feet below pad grade. An additional twelve (12) inches were scarified, moisture conditioned and compacted. 8. Soils previously removed from the building. areas were replaced in thin lifts and compacted in place. Then fill materials consisting of onsite soils were placed in thin layers and compacted into place. 9. The pads were overexcavated a minimum of five (5) feet beyond the building limits or more in most instances. The approximate limits of the overexcavations are indicated on the plans. 10. The building locations indicated in this report are as designated on the site grading plan and may vary from those indicated on the architects master plan. 11. A total of two hundred three (203) compaction tests are reported herein. The initial three hundred seven (307) tests are reported in the referenced interim report. 12. Test results indicate that a minimum of ninety (90) percent of maximum density has been obtained in the areas tested. . 13. The test locations are approximate and were determined by pacing and sighting from prominent field features. In our work, we have relied on topographic and survey information provided by others. 14. Based upon observations and testing during the grading operations, from April 14, 1992 through May 20, 1992, on this project, it is our opinion that the intent. of the recommendations of the referenced Geotechnical Engineering Report as well as the ordinances of the City of La Quinta, California have been met. June 18, 1992 -3- B7-2083-P3 92-06-727 15. As used herein, the term 'observation' implies only that we observed the progress of work we agreed to be involved with, and performed tests on which together we based our opinion as to whether the work essentially complies with the job requirements. 16. With any manufactured product there are statistical variations in its uniformity and in the accuracy of tests used to measure its quality. As compared with other manufactured products, field construction usually presents large statistical variations in its uniformity and accuracy of test results used to measure its quality. Thus, even with very careful observation and testing, it cannot be said that all parts of the product comply with the job requirements and the degree of certainty is greater with full-time observation than it is with intermittent observations and testing. Therefore, our opinion, based on observing and testing the work means that there is only a statistically based, reasonable certainty, that the work essentially complies with the job requirements. 17. We make no warranty, express or implied, except that our services were performed in accordance with engineering principles generally accepted at this time and location. 18. It is recommended that Earth Systems Consultants be provided the opportunity for a general review of any changes to the final design and/or location of the proposed structures in order that earthwork and foundation recommendations may be properly interpreted. If Earth Systems Consultants is not accorded the privilege of making this recommended review, we can assume no responsibility for misinterpretation of our recommendations. 19. This report is issued with the understanding that it is the responsibility of the owner, or of his representative, to insure that the information and recommendations contained herein are called to the attention of the architect and engineers for the project and are incorporated into the plans and specifications for the project. It is also the owners responsibility, or his representative, to insure that the necessary steps are taken to see that the general contractor and all subcontractors carry out such recommendations in the field. It is further understood that the owner or his representative is responsible for submittal of this report to the appropriate governing agencies. If there are any questions concerning this report, please do not hesitate to contact this office. Respectfully submitted, E TH SYSTEMS CO L .NTS 0 Kurt A.
