Foundations shall have a minimum <br />embedment depth of 12-inches below outside adjacent grade. Continuous and isolated <br />footings should be designed in accordance with the structural engineer requirements. <br />Reinforcement of footings should be per the structural engineer’s design. <br /> <br />15.5 Foundation Construction <br /> <br />The following preliminary recommendations assume very low to low expansive soils <br />near finish pad grade. <br /> <br /> All footing excavations should be observed by the geotechnical consultant <br />prior to placement of reinforcing steel, in order to verify proper embedment <br />into suitable soils. <br /> <br /> If foundations and or slabs will adjoin any likewise existing surfaces, it is <br />recommended that the structural engineer provide details for doweling to <br />minimize cracking along the interface. Similarly, the architect should provide <br />detailing for the flooring materials (e.g. antifracture membranes) or <br />expansion joints to accommodate for any slight differential movement at <br />connections. <br /> <br /> Site soils are suitable for use as compacted fill if they are processed in <br />accordance with the recommendations in Appendix C. <br /> <br />57 of 100 <br />1327 S Grand Ave <br />12/12/2024
