(AKA) has provided geotechnical consulting services during post- grading operations at the site. These services were provided on a part-time, as-requested basis from October 2007 through April 2009. 2.0 SCOPE OF SERVICES Albus-Keefe & Associates, Inc. has performed geotechnical consulting services as described below. I . Provided observation of footing excavations for the proposed buildings. . Provided observation of footing excavations for the retaining walls. I • Provided observation and/or density testing of retaining wall backfill. . Provided observation and/or field density testing during backfill of sewer, domestic water, storm drain, drain line and common utility trenches. I . Provided observation and field density testing for curb-and-gutter and pavement subgrade. . Provided observation and field density testing of aggregate base placed within pavement areas. I • Provided observation and field density testing of asphalt concrete placed withinpavernent areas. Provided laboratory testing of representative earth materials encountered during site post-grading operations. I . Prepared this report summarizing our observations, results of field and laboratory testing, and presenting opinions and recommendations relative to future development of the site. 1 3.0 PROJECT PLAN AND JURISDICTION I . The layout of the subject project i 's shown on the plan entitled "Grading Plan for Poinsettia Commons, City of Carlsbad", Sheets 2 through 4 of 8, at a scale of 1 inch equals 20 feet, prepared by Project Design Consultants, dated April 2, 2007. These plans are used as the base map for the I .enclosed Density Test Location Map, Plates 1, 2 and 3. The limits of this report and approximate locations of field density testing performed by this firm are shown on the Density Test Location Map. I Construction was performed under the jurisdiction of the City of Carlsbad. 7-7 Li I ALB US-KEEFE & ASSO CIA TES, INC. Trammell Craw Residential, Southern California April 8, 2009 J.N.: 1286.01 I Page 2 4.0 FIELD OBSERVATION 4.1 GENERAL Albus-Keefe & Associates, Inc. performed post-grading field observation and testing services on a part-time, as-requested basis. Requests and scheduling were made through Trammell Craw Residential's onsite superintendent. As such, our services did not include continuous observation of all trench/retaining wall backfill, subgrade preparation operations, or other work not reported herein. Periodic observations by our staff and discussions with the contractors indicate that the work was performed as discussed in the following sections. 4.2 FOUNDATION EXCAVATION FOR BUILDINGS Prior to placement of concrete, footing excavations for the proposed buildings at the subject site were observed and probed by this firm to verify that the excavations exposed competent bearing soils. Based on this firm's observations, engineered compacted fill was exposed at the bottom of footing excavations and was considered to be adequate for the intended use at the time of observation. 4.3 FOUNDATION EXCAVATION FOR RETAINING WALLS Prior to placement of concrete, footing excavations for the proposed retaining walls were observed and probed by this finn to verify that they had been excavated into competent bearing soils. Based on this firm's observation, engineered compacted fill was exposed at the bottom of footing excavation and was considered to be adequate for the intended use at the time of observations. 4.4 RETAINING WALL BACKFILL Periodic observations by our staff and discussions with the contractor indicated backfill materials were generated from excavation for construction of retaining walls. Backfill materials were placed in 6- to 8-inch loose lifts; moisture conditioned to near or slightly higher than optimum moisture content and compacted. 4.5 UTILITY TRENCHES Where observed, pipes and/or conduits installed in the storm drain, sewer, water, and common utility trenches (gas, electric, telephone and cable TV) were shaded with imported sand or gravel to at least 12 inches above the top of pipes. The remainders of the trenches and the drain line trenches were I backfilled with onsite soils. The soil backfill was brought to near or slightly above optimum moisture contents, placed in lifts up to approximately 12 inches in thickness and compacted. 4.6 SUBGRADE Subgrade soils for curb-and-gutter and pavement areas were observed and tested after preparation by the contractor. Areas found to be soft and/or yielding were removed and/or re-compacted. t7l ALBUS-KEEFE & ASSOCIATES, INC. Trammel! Craw Residential, Southern California April 8, 2009 J.N.: 1286.01 Page 3 4.7 AGGREGATE BASE Aggregate base sections for pavement areas were placed; moisture conditioned, and then compacted with steel-drum rollers. 4.8 ASPHALT CONCRETE The asphalt concrete sections were placed and then compacted with steel-drum rollers. 5.0 FIELD DENSITY TESTING Scheduling and requests for field density testing by this firm's representative were made by the client's site superintendent. The in-place density of fill materials were determined in accordance with ASTM D1556 (6-inch sand cone) and AS D2922/D3017 (nuclear gauge). When field density testing was requested, field density testing of trench and retaining wall backfill was generally performed for approximately 2 vertical feet of fill placement and at roughly 200-foot horizontal intervals. Pavement subgrade;base, and asphalt concrete were roughly tested on the basis of one test for every 6,000 square feet of pavement areas. The results of field density tests were comparedro the maximum dry density determined in accordance with ASTM D1557-02 for soil and aggregate base and ASTM D2726 for asphalt concrete to evaluate relative compaction. Where test results indicated a relative compaction less than 90% for onsite trench/retaining wall backfill and subgrade soil, or 95% for aggregate base, asphalt concrete and offsite trench backfill and pavement subgrade, the area of substandard material was either re-compacted until subsequent testing indicated compliance with the project specifications, or the substandard materials were removed and replaced with material compacted to the project specifications. The results of field density tests are presented in Appendix A, on Table A. The approximate test locations are shown on the Density Test Location Map. 6.0 LABORATORY TESTING Samples deemed representative of the onsite and imported materials were collected and tested in the laboratory to determine maximum dry density and optimum moisture content. Maximum dry density and optimum moisture content tests were performed on selected samples in general conformance with ASTM D1557-02 for soil and aggregate base, and ASTM D2726 for asphalt concrete. Pertinent test values are presented on Table B in Appendix B. 7.0 CONCLUSIONS Earthwork carried out under the observation and testing by Albus-Keefe & Associates, Inc. was performed in substantial conformance with the project plans and specifications, the grading codes of the City of Carlsbad, and applicable portions of the project geotechnical requirements. (Albus-Keefe & Associates, Inc. is not responsible for line and grade). I Post-grading work for the site has been observed and tested by this firm in a manner consistent with the standard of care currently exercised by members of the profession practicing in the same general locality under similar conditions.
