When the actual column type,size <br /> and total loading has been determined,each column footing condition should be reviewed to determine the required round <br /> column pad size and thickness. Although actual concrete compressive strength(PSI)may vary,it is assumed that at a <br /> minimum,Plain Structural Concrete(2500 PSI)will be used for column footings sized herein. Soil types and bearing <br /> capacities must also be verified at each site. Consult with the local Building Code Official prior to using this table. <br /> BCSD-MH009-042503 <br />
