Bar Bending is the process of bending reinforcing steel into shapes required for reinforced concrete construction. Now, Bar Bending Schedule is a list of reinforcement bars that is related to a given RCC work item, and is presented in a tabular form for easy visual reference. This table summarizes all the needed particulars of bars – diameter, shape of bending, length of each bent and straight portions, angles of bending, total length of each bar, and number of each type of bar. This information is a great help in preparing an estimate of quantities.
Making Bar Bending Schedule depends on the structure one is working on. It varies with the members of the structure, i.e, beams, columns, slabs will have separate BBS. It is preferable to look at the drawing and prepare the BBS. Bar bending schedule is used to communicate the design requirement of reinforcement steel to the fabricator and execution team and to enumerate the weight of each size of steel.

When compared to common quantity take offs, preparation of bar bending schedule needs excessive time for calculation. These calculations include cutting length, deduction of bend allowance within cutting length and summary of weight of each size separately. Insertion of any omitted items or revisions in the drawing may lead to repeated calculations and consume ample time.
To overcome aforementioned difficulties and to optimize productivity, the excel sheet template is made available. It can be used in various stages of construction such as estimation, steel procurement, execution, billing and steel reconciliation. All the calculations are done automatically. The sheet even has the shapes which you can relate to the bars and as you mention the dimensions, they are displayed along the shape of the bar.
