How do you install rebar stirrups at corners on footings?

To install rebar stirrups at corners on footings, first, cut the rebar to the required lengths for the stirrups. Bend the rebar into a U-shape, ensuring the legs are long enough to be anchored into the footing. Position the stirrups at the corners, tying them securely to the vertical rebar using wire ties to maintain proper spacing and alignment. Finally, ensure that the stirrups are placed at the correct height before pouring the concrete.
