For small projects of civil engineering, we generally use various thumb rules for re-incorcement calculations. But for large projects, bar bending schedule is prepared based on standard shape codes. This helps in avoiding wastage of expensive steel material. It is also easier to cut steel bar for reinforcement as per design.
