The column is being broken down to a considerable depth to expose the dowel bars, which is incorrect. By the time the staircase is constructed, the column will have gained its full strength, preventing proper bonding between the two. This led to the crack in the staircase. Already The TKC has instructed to construct the staircase simultaneously with column concrete, but both construction is being done with a wide intervalof time, so lt lead to the weakening of the concrete.
