When the actual <br /> column type,size and total loading has been determined,each column footing condition should be reviewed to determine <br /> the required square footing size and thickness. Although actual concrete compressive strength(PSI)may vary,it is <br /> assumed that at a minimum,Plain Structural Concrete(2500 PSI)will be used for column footings sized herein. Soil <br /> types and bearing capacities must also be verified at each site. Consult with the local Building Code Official prior to <br /> using this table. BCSD-MH008-042503 <br />
