A bar bending schedule is a list that details the size, length, shape and number of reinforcement bars used in a construction project. It is prepared before the construction work starts and helps to ensure that the correct amount and type of reinforcement is used in the concrete structures, such as beams, columns, slabs, etc. The schedule serves as a guide for the steel benders and helps them to bend and cut the reinforcement bars accurately as per the construction drawings.
