(TESD) has conducted grading observations and compaction testing during the street improvements at the above referenced project site. Services described herein were provided by TESD from October 13, 2006 to January 25, 2007. Street improvements were carried out on the intersection of Faraday Avenue and El Camino Real. The extent of the improvements on Faraday Avenue extended from 600 feet west of El Camino Real to Palmer Way; and on El Camino Real from Faraday Avenue to Station No. 103+54. A representative of this office observed the street improvements in accordance with the approved plans and specifications. The subgrade was scarified 8 inches moisture conditioned and recompacted. Reconstruction of the typical pavement sections consisted of 4 inches of asphalt concrete over 6 inches of aggregate base on Faraday Avenue and 6 inches thick asphalt concrete and aggregate base layers respectively on El Camino Real. Summaries of laboratory and field compaction test results are provided in Appendix A, Tables 1 and 2, respectively. On site and import materials were used for the roadway grading operations. The fill was placed, compacted, and tested for compliance with a minimum 95% relative compaction requirement. It should be noted that the precision of the field and laboratory maximum dry density test results are subject to variation inherent with testing procedures and heterogeneous material characteristics. Quantitative values of testing precision have been documented by the American Society of Testing and Materials. For example, results indicate the accuracy of the ASTM D-1557 test to be plus or minus 4 percent of the mean density. Based on this information, relative compaction results should be interpreted as approximate values subject to variations in lateral and vertical directions. Survey lines and elevations relative to grade modifications, final design grades, locations of various elements, etc., were established by others. Field Monitoring services provided by this office, consisting of visual observation of compaction operations and random in-place density tests, are intended as assistance to the owner/client in monitoring Testing Engineers San Diego, Inc.

The presence of our field representative during the work progress did not involve any direct supervision of the contractor/subcontractor. Technical advice and suggestions were provided upon request based upon the results of the tests and observations. In any case, no warranty or responsibility for the contractor's performance is intended or implied. Based on the observations and testing made during construction by TESD representatives, it is our opinion that the roadway improvements were constructed in general conformance with the approved project plans and specifications and is considered suitable for the intended use.
