The document summarizes the design of an isolated square footing to support a 400x400mm reinforced concrete column with a vertical load of 50kN. It describes the 7 steps taken: 1) sizing the footing, 2) checking two-way shear, 3) designing flexure reinforcement, 4) checking one-way shear, 5) checking development length, 6) checking bearing stress, 7) distributing reinforcement. The final footing dimensions are 2x2m with a depth of 250mm. 12mm diameter bars are provided at 300mm spacing with 50mm clear cover and 740mm development length to satisfy design requirements.
