Tests were performed at random locations in accordance with ASTM D 2922-81, Method A or B; and ASTM D 3017-88 Nuclear Density Test Procedure. ' Tests were performed as per authorization of Mr. Dave Smoley. The estimated locations of the tests are presented on the attached plan with their results being summarized on the attached test report sheet. A total of 10 density tests were performed. Test results indicate that after reworking areas of low density, a minimum of 95% relative ' compaction has been obtained within the areas tested. The maximum density and optimum moisture were determined in the laboratory in accordance with ASTM D 1557-91, Method A or C. Test results are as follows: Soil Description USCS Maximum Density Optimum Moisture ' Brown silty Sand, fine SM 115.7 pcf 11.7% grained Base materials --- 138.0 pcf 6.5% ' DISCUSSION: ' 1. The project is located on the northeast corner of Washington Street and Highway 111 in the City of La Quinta, California. ' 2.

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 surveying information provided by others. 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 although the degree of certainty is greater with full-time observation and testing than it is with testing only. Therefore, our opinion based on testing the work means that there is only a statistically based tprobability that the densities obtained comply with the job requirements.

' Submitted herewith is a report of testing and intermittent observations performed during the grading on the above referenced project. Grading operations were performed by Earth Sculptures using conventional heavy equipment. Testing was performed as per authorization of Mr. Parin Columna. Test results are presented on the attached test report sheet with their estimated locations plotted on the accompanying plan. Compaction tests were performedin accordance with ASTM D 2922-81, Method A or B, and ASTM D 3017-88 Nuclear Density Test Procedures. Maximum Density -Optimum Moisture is determined in the laboratory in accordance with ASTM D 1557-91, Method A or C. Test results are as follows: Soil Description USCS Maximum Density Optimum Moisture ' Brown silty Sand,' fine SM 115.7 pcf 11.7% grained October 3, 2002 - 2 - File No.: 08521-04 02-10-711 DISCUSSION: 1 2 3 4 5 6 7 The project is located on the northeast corner of Washington Street and Highway 111 in the City of La Quinta. Prior to grading, the site consisted of a previously rough graded lot with sparse desert vegetation. The proposed development consists of a commercial structure of masonry and wood frame construction. The scope of our work was based on the referenced geotechnical engineering report update, and plans and staking by others. The site was cleared of any pre-existing vegetation and prewatered prior to grading operations. The building pad was over -excavated to a depth of 2 feet below pad grade. An additional 12 inches was processed by moisture conditioning and compacting. Fill materials consisting of previously removed soils were placed in relatively thin lifts and compacted into place. A total of 37 compaction tests were performed. Test results indicate that a minimum of 90% of maximum dry density has been obtained in the areas tested. 10. The test locations are approximate and are determined by pacing and sighting from prominent field features. In our work, we have relied on topographic and survey information provided by others. 11. Based upon intermittent observations and testing during the grading operations, from September 11 through September 23, 2002 on this project, it is our opinion that the grading has met the intent of the recommendations of the referenced Geotechnical Engineering Report Update, as well as the grading ordinances of the City of La Quinta. 12. As used herein, the term "observation" implies only that we observed the progress of work we agreed to be involved with, and performed test on which together we based our opinion as to whether the work essentially complies with job requirements. 13. 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 EARTH SYSTEMS SOUTHWEST October 3, 2002 - 3 - File No.: 08521-04 02-10-711 ' with intermittent observations and testing. Therefore, our opinion based on observing g p g and testing the work means that there is only a statistically -based, reasonable certainty ' that the work essentially complies with the job requirements. 14. 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. 15. It is recommended that Earth Systems Southwest (ESSW) 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 ESSW is not accorded the privilege of making this recommended review, we can assume no responsibility for misinterpretation of our recommendations. ' 16. 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 ensure 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.

Mr. Dave Smoley Project: Ross Dress for Less ' One Eleven La Quinta Center La Quinta, California I Subject: Report of Field Density Testing "V" Gutter and Parking Lot Subgrade, and Parking Lot Base t On May 6, 7, and 8, 2003, a representative of our firm performed density tests at the above referenced project. Tests were performed at random locations in accordance with ASTM D 2922-81, Method A or B; and ASTM D 3017-88 Nuclear Density Test Procedure. ' Tests were performed as per authorization of Mr. Dave Smoley. The estimated locations of the tests are presented on the attached plan with their results being summarized on the attached test report sheet. A total of 10 density tests were performed. Test results indicate that after reworking areas of low density, a minimum of 95% relative ' compaction has been obtained within the areas tested. The maximum density and optimum moisture were determined in the laboratory in accordance ' with ASTM D 1557-91, Method A or C. Test results are as follows: ' Soil Description USCS Maximum Density Optimum Moisture Brown silty Sand, fine SM 115.7 pcf 11.7% ' grained Base materials --- 138.0 pcf 6.5% ' DISCUSSION: ' 1. The project is located on the northeast corner of Washington Street and Highway 111 in the City of La Quinta, California. ' 2. Prior to our arrival on May 6, 2003, the "V" gutter subgrade had been moisture conditioned and was ready for testing. r . ' May 21, 2003 ` = 2 - File No.: 08521-04 03-05-767 ' 3. Prior to our arrival on May 7, 2003, the parking lot subgrade had been moisture conditioned and was ready for testing. ' 4. Prior to our arrival on May 8, 2003, the parking lot base had been moisture conditioned and was ready for testing. ' 5. The purpose of testing was to observe compliance with the minimum requirements of the City of La Quinta. LIMITATIONS ' The test results summarized in this report present the moisture and density only at the locations and depths tested on the specified dates. The summarized field and laboratory .tests were performed in accordance with engineering principles generally accepted at this time and location. ' No opinion is expressed as to the uniformity of the material or compaction. No guaranty or warranty of the contractor's work is made or implied. 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 surveying information provided by others. ' 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 although the degree of certainty is greater with full-time observation and testing than it is with testing only. Therefore, our opinion based on testing the work means that there is only a statistically based ' probability that the densities obtained comply with the job requirements. This report is issued with the understanding that it is the responsibility of the owner, or of ' his representative to ensure that this report is submitted to the appropriate governing agencies.

This shmdarJ has been apprq.edft,r Use by agencies of rhe Department r f Defence. I- Scope I.1 This practice covers the installation of suspension sys- tems for acoustical tile and lay -in panels. It is applicable to contractors whose services are utilized for installing acoustical ceilings and to other trades if their activities are responsible for interference with ceiling components or performance as de- fined in this recommended practice. 1.2 While the practices described in this document have equal application to rated fire -resistive suspension systems, additional requirements may have been imposed to obtain the fire endurance classification of particular floor -ceiling or roof - ceiling assemblies. These details should be obtained from the manufacturers. 1,3 Similarly, additional detailing may be necessary to meet sound attenuation requirements when ceiling plenums extend over contiguous rooms. These, too, should be obtained frorn the manufacturer of the acoustical material employed. 1.4 The values stated in inch -pound units are to be regarded as the standard. 1.5 While many of the practices descrioed in this practice have application to the installation of metal suspension systems in exterior environments, the specific design of exterior ceiling installations requires the review and approval of the architect, engineer, or both, who are responsible for the construction of the building or modifications to an existing building. While recommendations from the manufacturer should be solicited, it remains the final responsibility of the a:chitect/engineer to ensure proper application of the materials in question. 1.6 This standartl does not purport to address of the safely concerns, if any, asscwiared with its use. 1, is the responsibility of the user of this standard to establish appropriate safety and health practices and determine rhe applicability of regulatory limitations prior to use. 2.

UBC section 2501A.5.4.2 Ceiling fixtures states " All recessed or drop-in lighting fixtures and grilles shall be supported directly from the fixture housing to the structure above with a minimum of two 12 gage wires located at diagonally opposite comers—_." It appears the actual installation method; number of twists, etc., though not specified in the UBC, would be the same as the installation method for the ceiling grid itself.
