About this detail

Added reinforcement layout required around non-grouped openings in a concrete slab. Top and bottom reinforcing bars are placed around the perimeter of the opening, alongside diagonal corner bars for crack control. Specific sizes such as number 6 top and bottom bars, number 5 top and bottom bars, and number 4 bars at twelve inches spacing are called out for different conditions. Dimensions dictate minimum clearances, maximum opening sizes, and bar extension lengths. Where these conditions cannot be met, the installation must be submitted to the structural engineer for review.
