' . - ' . .' ., . -' I In accordance with your request this report has been prepared to present the results of field observations and tests performed during the grading for the Kellas Residence Jn Carlsbad, I California Our services were performed between July 12 and July. 25, 2006 To assist in 1 determining the locations and elevations of our vi field density tests, we were proded with a Grading Plan prepared by Logan-,E ngi nee ring dated January 24, 2006, which defines the general extent of I I site grading 1 PROJECT DESCRIPTION 11 SITE PREPARATION 1.1.1..Primary Equipment I The primary equipment employed for the site mass grading operations included 1 I I I I - - I Laurie and Bill Kellas August 2 2006 I .

CLEARING AND GRUBBING Site preparation began with the clearing and grubbing of the existing vegetation and organic matter I ' at the proposed development area The material generated from the operations was exported from the site. -. • ,• '. . . . •. . I i 3 LOT GRADING 7 0 The potentially, compressible topsoil and subsoil deposits were removed 8 to 11 feet 'from'the areas I to receive fill and from beneati settlement-sensitive improvements Expansive topsoils were exported from the site The bottoms of the removal areas typically exposed dense terrace deposits The removals extendd laterally to the entire extent of the proposed structure Following the I removals the exposed surface was scarified to a depth of 12 inches, moisture conditioned and compacted until field density tests indicated a minimum of 90 percent relative compaction..Optimum I moisture and relative compaction are based on the ASTM D 1557-00 laboratory test method The excavated soils and import soils were placed as compacted fill Fill was placed in 6 to 8 inch I lifts moisture conditioned to near optimum moisture content and compacted until field density tests indicatedá minimum of 90 percent relative compaction. Compaction Was.achidved by means of a' Case 145013 with an attached sheep's foot roller. This process continued until planned elevations I were reached I i 4 DRIVEWAY The driveway preparation essentially consisted of removing the existing topsoil and subsoils to a depth of 2 feet The exposed surface was scarified, moisture conditioned and compacted Fill soils to bring the driveway to grade have not yet been placed The location is noted on plate No 1 I 2 FIELD OBSERVATIONS AND TESTS Field observations and density tests were performed by .a representative of SCS&T during the earthwork operations at the locations shown on Plate No 1 The density tests were performed I according to ASTM D 2922-01 (nuclear gauge) procedures The results of the tests are shown on Plate ,No. The accuracy of the in-situ density test locations and elevations is a function of the accuracyof the .survey control provided by others than SCS&T representatives. Unless otherwise •" noted, their locations and elevations were determined by pacing and hand level methods and should be considered accurate only to the degree implied by the method used I I Laurie and Bill Kellas August 2 2006 I : -Kellas Residence . . . 'SCS&TNo. 04.11290-4 Page3 I As used herein, the term "observation" implies only that we observed the progress of work we were involved with, and performed field density tests which, in conjunction with our observations were the base for our opinion as to whether the work was performed in substantial conformance with the I geotechnical recommendations and the requirements of the applicable agencies I 3 LABORATORY TESTS Maximum dry density determinations were performed on representative samples of the soils used in I the compacted fills according to ASTM 0 1557 The results of these tests presented on Plate No 2 were used in conjunction with the field density tests to determine the degree of relative compaction of the compacted fill - The expansion potential of thp prevailing foundation soils was determined using LJBC Test Method 18-2 The results of this test, shown on Plate No 2 indicate non-detrimentally expansive soil I conditions I 3.1. REMAINING WORK The following operations remain to be completed It is recommended that field observations and relative compaction tests be, performed during.-these operations to verify that these operations are I being performed in accordance with job requirements and local grading ordinances I . Final grading for the driveway, Subgrade preparation for hardscape areas, Preparing and placing the driveway subgrade course I . Backfilling of retaining walls, Backfilling of underground utility. trenches - 1 / 4 CONCLUSIONS I Based on our field observations and the in-place density test results, it is our opinion that the building pad, slopes, and roadway preparaton and compaction were performed substantially in accordance with the recommendations contained in the referenced geotechnial report(s),-the City of Carlsbad and the California'Building Code I 5 LIMITATIONS This report covers only the services performed between July 12 and July 25, 2006 Our opinions are based on our observations and the relative compaction test results and are limited by the scope of 1 the work that we agreed to perform Our work was performed in accordance with the currently 1 Laurie and Bill kellas August 2 2006 I Kellas Residence .' .. . . . ..
