<br /> <br />ASSOCIATED SOILS ENGINEERING, INC. Project No.: 7160.23 <br />2860 Walnut Avenue, Signal Hill CA 90755 January 23, 2024 <br />Tel: (562) 426 -7990 * Fax: (562) 426 -1842 Page 17 <br />On-site soils and import materials approved for use as fill should be placed in horizontal lifts not <br />exceeding 8 inches in loose thickness, moisture conditioned to a minimum of two (2) percentage <br />points above optimum moisture content, and compacted to a minimum 90 percent relative <br />compaction. Unless otherwise stated, the measurement of relative compaction in this report <br />should always refer to ASTM D1557-12(2021) Test Method. <br /> <br /> <br />5.2.7 Tests and Observations: <br />All subgrade preparation, compaction, and backfill operations should be performed under the <br />observation of and testing by the Geotechnical Consultant's field representative. An adequate <br />number of field tests should be taken to ensure compliance with this report and local ordinances. If <br />it is determined during grading that site soils require overexcavation to greater depths for obtaining <br />proper support for the proposed structures, this additional work should be performed in <br />accordance with the recommendations of the Geotechnical Consultant. <br /> <br />5.3 Foundation Design <br />Provided that the site grading recommendations presented in Section 5.2.3a above are incorporated in <br />project planning and design, and implemented during site construction, it is ASE’s opinion that the Building <br />could be supported by conventional footing foundation. <br /> <br />5.3.1 Conventional Shallow Footing Foundation: <br />a) Minimum Footing Dimension and Reinforcement: <br />In order to mobilize sufficient soils bearing capacity supporting the new footings for the <br />Building or any ancillary improvement (i.e. site walls, trash enclosures, signs, etc.), it is <br />recommended that the following tabulated minimum footing embedments, widths and <br />reinforcements for various footing types be considered. <br />Minimum Footing Dimension & Reinforcement <br />Continuous Spread Footing/Strip Footing Isolated Pad Footing <br />Depth (1) <br />(in) <br />Width <br />(in) Reinforcement (2) Depth (1) <br />(in) <br />Width <br />(in) Reinforcement (2) <br />18 15 <br />Four #4 bars – two <br />near the top and two <br />near the bottom <br />18 24 square <br />Four #4 bars – two near <br />the top and two near the <br />bottom, applied bi-axially <br />(1) Footing embedment measured from the nearest adjacent lowest soils grade. <br />(2) Based strictly from geotechnical point of view. <br /> <br />Foundation design details such as concrete strength, reinforcements, etc. should be established <br />by the Structural Consultant.
