Gentlemen: According to your request and signed authorization, Soil Tech, Inc. has performed field observations and in-place density testing during the post grading operations for the referenced site. Submitted, herein, are the results of the findings and the supporting field and laboratory data. 1.0 PROJECT DESCRIPTION The subject site is to be developed with the construction of two (2) single story, slab-on- grade medical office buildings and accompanying asphaltic concrete driveway and parking areas with concrete curbs and gutters. Each building will have two (2) units. Each unit will range from 2,008 to 2,870 square feet in size. Unit No. 4 will contain a "Linear Accelerator Room", which will be constructed of reinforced concrete walls, floor, and ceiling. The walls, ceiling, and floor will be 2.0 to 4.5 feet, 2.0 to 4.0 feet, and 2.0 feet in thickness, respectively. The remainder of the structures will be constructed of wood frame and stucco. 2.0 SITE DESCRIPTION 2.1 Location: The subject property comprises approximately 1.02 acres and is located on the northwest side of Winchester Road and approximately 240 feet northeast of the centerline of Ynez Road in the City of Temecula, Riverside County, California. The subject site is bounded on the northwest side by the Santa Gertrudis Creek Channel. 2.2 Topoaraphv and Surface Conditions: Prior to the time of the post grading, the site consisted of a previously rough graded building pad area for associated parking lot area l\ SOIL TECH, INC.

Project Number: T 4086.C1 April 1994 Page 3 for two (2) proposed single story, slab-on-grade medical office buildings and associated parking lot area; asphaltic concrete driveway and parking areas with concrete curbs and gutters are presented in Reference NO.2 Geotechnical Report of Rough Grading. SCOPE OF WORK Time of Post Gradina: Post grading operations were conducted from September 21, 1993, through March 14, 1994. Contractor and Eauipment: The post grading operations for the preparation of the subgrade soils and the placement of aggregate base material for the proposed asphaltic concrete driveway and parking areas and associated concrete sidewalks curbs and gutters were performed by Edmondson Construction. One (1) Ingersul Rand DD-35 vibratory roller, one (1) Ford 545 skiploader, and a water truck were used during the grading process. Post Gradina Operations: The post grading consisted of footing and foundation observations performed on September 22, 1993, for the proposed Linear Accelerator Room located within Unit No.4; interior and exterior footing observations were performed on November 10, 1993, for all the remaining foundations for the proposed building units. Compaction testing was performed for the subgrade and aggregate base grade sections for the proposed concrete sidewalk, curb and gutters areas, and asphaltic concrete parking lot and driveway areas. The sidewalk, curb, gutter, and pavement areas were generally graded to the elevations noted on the Grading Plan. However, the actual locations, dimensions, elevations, etc., were determined by others and should be verified by the project Civil Engineer. During the construction of the "Linear Accelerator Room", tests were performed on the Portland Cement Concrete used, ~ SOIL TECH, INC. I . I . I . I . . . . I I I . . . .

Project Number: T4086-C1 April 1994 Page 4 4.0 TESTING 4.1 Field TestinQ: 4.1.1 Soil and AQQreQate Base Material: Field in-place density and moisture content testing were performed during the preparation of subgrades and the placement of the aggregate base materials in general accordance with ASTM D2922-81 (90) and ASTM D3017-88 procedures for determining in-place density and moisture content respectively, using nuclear equipment. The test results are presented in Appendix I. Exhibit I. Detailed information regarding in-place density test locations are presented on the Post Grading Report Site Plan presented in Appendix III. 4.1.2 Concrete: The concrete used in the construction of the "Linear Accelerator Room" was sampled from the delivery trucks in general accordance with ASTM C172 procedures. Slump tests were performed on concrete sampled from the trucks in general accordance with ASTM C143 procedures. Specimens for strength tests were made from the concrete supplied to the project in general accordance with ASTM C31 procedures. The field test results are presented in Exhibit II In Appendix I. 4.2 Laboratorv TestinQ: The following laboratory tests were performed as part of our services during the post grading of the subject site. 4.2.1 Soil and AQQreQate Base Material: Maximum dry density - optimum moisture content relationship tests were conducted on samples of the materials used for subgrade and aggregate base for proposed parking lot and driveway areas and their associated curb I gutter and sidewalk areas. The tests were performed in general accordance with ASTM D1557-78(90) procedures. The test results are presented in Appendix II, Exhibit III. 4.2.2 Concrete: Strength tests were performed on specimens of hardened concrete used in the construction of the "Linear Accelerator Room" in general accordance with ASTM C39 (p SOIL TECH, INC.

The specimens were made and stored in general accordance with ASTM C31 procedures. The compressive strength test results are presented in Exhibit IV in Appendix II. EARTH MATERIALS The natural earth materials encountered on the site at subgrade elevations generally consisted of a brown silty sand. Import material consisted of a Class 2 Aggregate Base material. CONCLUSIONS AND RECOMMENDATIONS Based on the observations and tests performed during post grading, the subject site in the areas noted has been completed in accordance with the project plans and specifications, the Grading Code of the City of Temecula, and the Reference NO.2 Geotechnical Report.
