GEOTECHNICAL STUDY SUMMARY <br />continued <br />We recommend concrete slab-on-grade floors and exterior flatwork be a minimum thickness <br />of 4 inches. The actual slab thickness must be determined by the project structural <br />engineer <br />We recommend reinforcing the concrete slab-on-grade floors with a minimum of either, 11) <br />No. 3 reinforcing bars spaced at 24 inches on center, or (2j with an alternate steel <br />reinforcement as required by the project structural engineer. In general, the steel <br />reinforcement should be supported by concrete dobies to maintain the required clearances <br />according to the latest UBC standard. The project structural engineer should determine the <br />acceptable concrete cover. Crack control joints should be located as directed by the project <br />structural engineer. <br />~Korbmacher Engineering, Inc. <br />
